Natural beauty and Hollywood-style smile are main goals of esthetic dentistry, and today achieving great results in this field is not something out of the ordinary: modern clinics and experienced dentists possess everything they need to eliminate both inborn and acquired denture defects. Chips, worn spots, unpleasant enamel colour – to eliminate all these troubles and create right shapes, veneers are used in modern esthetic dentistry.
Aesthetic dentistry has been developing latest years by leaps and bounds. Cosmetics correction of dentition, whitening, and reconstructive dentistry are in high demand. Veneers, or plates laid on the teeth surface to protect them or improve their appearance, recently became one of the main means to make your smile magnificent. Bad shape of tooth, unevenness, chips, stain or improper color – all of those defects could be covered with veneers. In any medical center in Germany, which works in field of cosmetic dentistry, you find service of placing the veneers at very reasonable prices.
What are dental veneers?
It is possible to correct an unappealing smile with the help of veneers, which are placed on the teeth, returning them their beautiful appearance. To eliminate gaps between teeth, dentists also recommend veneers.
Our professionals advise to use only ceramic or plastic materials. This is mainly due to the properties of these materials, as well as their biocompatibility and durability.
Veneers are thin shells of different shapes. These include:
- Plates on the front teeth,
- Plates on the premolar teeth,
- Partial veneers that are used to correct chips,
- Veneers used to improve the alignment of the front teeth,
- Occlusal veneers (Tabletops) on the side teeth,
- Plates requiring only a minimally invasive intervention,
- Non-Prep veneers (not requiring intervention).
In most cases, partial ceramic veneers are installed. There is no clear distinction between different types of veneers, this is why such terms as 360° veneers and ¾ dental crowns exist.
The English term "veneer" means facade. In particular, both dentists and patients associate the term veneer with the classic restoration of front teeth. Synonyms: Coating, ceramic plate. Veneers are not always made of ceramics. Unusual composite veneers are also technically possible. Direct composite restorations are not to be mistaken with veneers.
Veneers are very thin ceramic relief plates. Their width depends on the individual shape of the patient's teeth, and the thickness can vary between 0.3 and 1.2 mm. Ceramic plates less than 0.3 mm thick are hardly safe in handling, both in the laboratory and in use.
The preparation time is rarely directly related to the thickness of veneers. If no change of the shape or positional corrections is required, the dental technicians will quickly customise the veneers to get the desired shape.
The aim of the ideal preparation when performing the correction of the veneer is to achieve its even thickness. This means that, in the best case, no special preparation is required. But sometimes the minimum thickness of the veneer requires polishing of the tooth enamel.
Therefore, precise assessment of the situation based on all the requirements is needed in each case. You should always consider whether it would be easy to perform further additive modeling. This also applies to the tooth length and the possible reduction of its cutting edge.
A white denture without significant gaps - that is a desirable appearance for many people. Veneers can help. But the expensive moldings also have disadvantages.
The teeth should be as snowy as snow and string together like pearls. But the wishful thinking does not always coincide with the reality: for example, through tea or red wine, the teeth are discolored, they are not close together, or one of the front teeth is a piece broken off. It does not have to stay like this. The dentist can help with veneers, for example. They are not cheap. And they can also cause problems.
The word "Veneer" comes from the English language and translates as "blinding". Veneers are thin casings for the teeth. This can be used to change both color and shape of teeth. Veneers are made individually. "As a rule, they are made of ceramic materials," explains the dentist and university teacher Dietmar Oesterreich. He is Vice President of the Federal Dental Association in Berlin. "Veneers can also be made of plastic," adds Gregor Bornes of Independent Patient Counseling Germany (UPD).
Veneers are primarily desired for aesthetic reasons. For medical reasons, they are not always necessary. Usually the front teeth are covered with veneers. Thus, the visual impression of the tooth front can improve. Veneers should be considered especially if teeth can not be treated with bleaches due to the nature of the discoloration. "Veneers should be used when the tooth structure is not completely destroyed and a crown is not yet necessary," our experts recommend.
What speaks against veneers?
Those who grit their teeth at night should refrain from veneers. The same applies to those who tend to bite or bite on pencils when biting. With such behavior, there is a risk that veneers can easily be reversed. Anyone who does not want to do without veneers despite gritting his teeth must wear a rail at night.
Attachment of veneers
The thin formwork with a circumference of often only half a millimeter are attached to the teeth with a special adhesive technique. Before that, the affected tooth usually has to be ground down. Veneers should not apply too thick and look like applied fingernails.
Difference between veneers and light veneers
There are two types of veneers. With the ceramic veneer treatment, the teeth are lightly ground. This means that a small part of the enamel is removed under local anesthesia. This ensures that the wafer-thin veneer fits the tooth perfectly. Because if the teeth are very close together, a little space has to be created for the veneer. However, there are also cases in which no hard tooth substance has to be removed, e.g. there is enough space between your teeth. Then the veneer can be glued on without preparing the tooth. These are the so-called light veneers or lumineers.
Important recommendation for every type of ceramic veneer restoration:
We recommend that you have professional teeth cleaning done before veneer treatment. Likewise, any caries therapy must be carried out at your home dentist, as well as leaky fillings replaced.
Veneers can only be glued over composite fillings, not over amalgam. Here, however, the size of the defect or the extent of the filling is decisive.
In order to prevent damage to the veneers or even detachment of the veneers, all intraoral piercings must be removed.
The veneers must be cleaned at least twice a year efficiently by a PZR (professional tooth cleaning) to ensure adequate care, especially of the adhesive edges.
We generally recommend a dental splint for the night for all veneer patients. In particular, if you tend to crunch or press or have CMD symptoms, you must wear a PROTECTIVE RAIL to protect the veneers at night. This must be made individually for you after veneer restoration. In rare cases, depending on the natural tooth structure and the ceramic used, the adhesive used can lead to slight differences in color perception.
Veneers cannot change color. However, the first changes in color begin to appear on the edges of the adhesive after five years at the latest. This depends on your lifestyle. Enjoying acidic foods, certain medications, tea, coffee and red wine can cause the edges of the adhesive to discolour more quickly.
Use dental floss and, if possible, interdental brushes to maintain the adhesive edges efficiently and to avoid excessive plaque deposits.
When can veneers be installed?
Veneers are mainly used for aesthetic purposes to solve visual dental problems and in case of dispositions. They mask optical defects and any signs of wear, especially in the frontal teeth area. Veneers compensate the difference in size and shape of the teeth and thus create an aesthetically pleasing dental arcade. If the unwanted shade of teeth cannot be removed by bleaching, veneers are the most suitable option of its correction. Thin ceramic shells also cover large gaps between the teeth ("diastema") and chipped teeth. Fragile, curved, extremely short or very narrow teeth can be covered using special cladding technique.
With the help of veneers it is also possible to mask the deformation and structural anomalies of teeth, as well as violations of their structure (dysplasia). Veneers also cover damaged tooth enamel with sites of fluorosis or which was exposed to the tetracycline antibiotics, as well as in the increased consumption of fruit juice.
Veneers: durable beauty, beautiful durability
Veneers are suitable for everyday use. Veneers are used for the long-term beautification of teeth. They are a true all-rounder, their range of indications is broad, whether it concerns the shape, function or color of teeth, for example:
- Wish for a lighter tooth color
- Gaps between teeth
- Shape improvement for teeth that are too small or too short
- Irregularities of teeth
- Spotty teeth
- unfavorable tooth position, open bite
- set back teeth
It is estimated that about half of all dental treatments with crowns can be better solved with ceramic veneers. Dental veneers offer a number of advantages over crowns and other conventional restoration techniques:
- Unsurpassed aesthetics: better to reach other people,
- Body compatible, closest to nature,
- High-performance ceramics: aesthetic, stable, bite-proof, hygienic,
- Durable, also available with an extended warranty,
- gentle on tissue (minimally invasive),
- Can also be used in difficult bite situations (deep bite, cover bite),
- Economical, The perfect anti-aging
In terms of material, veneers are pure ceramic veneers that are firmly glued to the teeth. Because of their special aesthetic qualities, they are mainly used on anterior teeth. But veneers are also suitable for building up worn molars, where they can withstand high functional forces. Caries defects can also be treated excellently with veneers.
Dental ceramics - next to nature
Veneers are preferably made from special dental ceramics. These materials come closest to nature and are physically similar to tooth enamel. This applies to hardness, abrasion resistance, acid resistance, hygienic ability, optical behavior and enables good looks with functionality and durability. White tone and light transmission can be selected individually. The hand of an expert is able to form perfect tooth restorations that surpass natural beauty.
When are veneers not suitable?
Jaw diseases such as bruxism affect the stability of veneers. Patients with such diseases of the dental system are recommended to resort to alternative methods. If the teeth are strongly chipped, veneers cannot be installed, and also we do not recommend to install veneers on teeth with old large seals.
In cases like this only a dental crown can provide the necessary external support. Patients with large areas of caries or with "jagged" teeth edges are recommended to use other methods of smile correction. For the successful aesthetic dental treatment you need to strictly follow the rules of oral hygiene.
How are veneers installed?
Talk to your dentist about all your individual (color) wishes. After the preliminary fitting and preparation of veneers, the dentist conducts professional dental cleaning to be able to tightly fix the veneers.
The dentist also takes an X-ray to make sure that the teeth are healthy inside. If the teeth have lost their healthy shade, the color of the veneer must first be compared to the adjacent teeth to obtain the appropriate color palette of the teeth.
Installation of veneers. How are veneers installed?
About 2 weeks later, ceramic veneers produced in a laboratory are attached to the outer surface of the teeth with a special plastic cement. Before that our experts pick up an adequate color and form of the ceramic plate. Prior to the installation the veneer is cleaned with water vapor, its internal surface is treated with acid, then washed with water and covered with a special cement.
Special braces are put on teeth ensuring that no saliva gets on the treated area during the procedure. The teeth are treated with phosphoric acid for a few seconds and then washed with water. The outer surface of the tooth is also covered with a thin layer of cement after the cleaning.
Adjacent teeth are protected from the contact with composite cement by a thin strip. The cement hardens only under the light of a special lamp, that is why the veneer can be set very precisely.
Usually veneers are glued one by one. First of all, residues of the composite cement should be removed from the gaps between adjacent teeth, in order not to allow the veneers to get glued together and cause tension. The veneers are cleaned and then polished. Finally, it is checked whether the patient can easily squeeze the upper and lower jaw and whether they feel any tightness.
The installation of veneers takes approximately 30 minutes. 1-2 weeks later the dentist checks the final result.
Is it possible to remove veneers in the future?
In order to securely fix the veneers, a small amount of tooth enamel has to be removed. Although it is completely safe, your teeth should be regularly inspected.
If after a few years your veneers have lost their original appearance, they can be replaced at any time.
The most innovative type of veneers are the ones that are glued to a slightly rough tooth surface. This method is called "no-prep method", as there is no need to heavily grind the teeth. A slightly rough tooth enamel is enough for the installation of a veneer.
However, this is not a long-term method of teeth restoration and does not fit all patients.
What should I choose? Types of dental veneers
Overlay veneers are divided by the way they are manufactured and the materials used, as well as by the way they are installed. It is impossible to say which veneers are better. The price, service life, difficulty of installation, or maintenance: the choice is individual.
Classification of veneers by material
Ceramic veneers are made of medical porcelain, or ceramics with high transparency. To install such a unit, the surface of the tooth must be grinded. The plate is only about 0.5 mm thick (to compare and understand the values: the thickness of a good contact lens is 0.8 mm).
The peculiarities of ceramic veneer fixation make them an effective tool not only for changing the teeth color and protecting them against the subsequent damage, but also for changing their shape and correction of gaps between them.
The ceramic veneers are expensive, and the feedback about them can vary depending on how well they were installed. It is important to know that the process of ceramic veneer installation cannot be reversed and errors in their installation are unacceptable.
The success and the future of the patient's dazzling smile depends largely on the teeth health (it is important to ensure they are healthy before the operation), the quality of the installation, doctor's qualification and the materials applied.
We advise you to choose the proven products from European manufacturers: Procera, Lava Filtek, Supreme, Gradia, Zirconzahn, Ceramage.
IPS Empress veneers (leucite glass-ceramic, also known as metal-free ceramics) are similar to the ceramic veneers, but due to a number of features can be allocated in a separate group. They are developed by IPS Empress, specializing in the production of high-tech materials and pastry dyes. The key advantage of the inserts by the IPS Empress company: there is no need to prepare the teeth. The main drawbacks are the cost and the need for regular maintenance of the material.
Lumineers, also called Hollywood veneers, are made of ultra thin ceramics with a thickness not exceeding 0.3 mm (in German clinics ultra thin Hollywood veneers with the thickness of 0.2 mm are installed). Lumineers do not change color over time and are easily removed if necessary. It is important to know that despite their small thickness, the Lumineers are extremely resilient, and their visible fragility is only an illusion.
Key advantages of Lumineers: the tooth enamel does not need to be removed, the procedure is fast (in Germany the installation process of Hollywood veneers is split into two sessions), painlessness procedure (not requiring anesthesia), no adaptive period: Lumineers are invisible on teeth (they cannot be seen even on the well-illuminated front teeth), the highest quality and safety of modern materials for the Lumineers.
It is possible to hide color defects, chips and deformations, abrasions and displacements of teeth, wedge-shaped defects, enamel fluorosis and other visible troubles using aesthetic Hollywood veneers. It is an effective and reliable way of teeth alignment, the only drawback being the price of the materials. But this drawback can be compensated by high service life of Lumineers: up to 15 years.
Zirconium veneers are rightfully considered to have the best quality among their class. Their use can guarantee the smile that will not tarnish, safety and full biocompatibility. Zirconium dioxide is safe and durable, but is difficult to process, which significantly affect the installation price of the dental veneers: creation of a three-dimensional model of a tooth, processing of zirconium on a milling machine, grinding of tooth enamel and the subsequent jeweller work: all of this is a complex and technological process.
Advantages of zirconium veneers: teeth look naturally in any light, drinks and tobacco do not stain zirconium, the material is anallergic, zirconium dioxide has the highest durability despite its low weight, temperature differences do not influence the material. It is important to know that their installation requires the use expensive equipment, and any error will cause the plate breakage and mechanical trauma to the mouth cavity.
A good German clinic with highly qualified doctors and positive feedback from its patients can be a good guarantee of a successful operation.
Composite veneers are made of the same moldable materials used for dental filling. They are formed inside the patient's mouth cavity (as opposed to all the mentioned above methods).
Composite veneers do not require teeth preparation and can be installed in one visit to the dentist. Unlike ceramic veneers, and other types of overlays, the composite veneers are less damage resistant, they can hardly conceal serious defects, and the material has an average light-resistance.
Classification of dental veneers by the installation method
Types of veneers can also be divided by the way they are installed. Direct veneers are installed and formed in the mouth of the patient, while indirect are made separately in laboratory conditions. The direct (therapeutic) way of veneer manufacturing is used when composite veneers are installed. For different kinds of ceramic or zirconia veneers the indirect (laboratory) way of their installation is used.
If you still have doubts about veneers, you can try to wear sample ceramic plates. Already on the first exploitation day of the wear you will feel the difference. You will see that your teeth are not the same as before. Everything will change: your articulation, smile and even the way you eat. Anyone who agrees to test the veneers before installing the final version, later avoids any unwanted surprises. Dentists also refer to samples of veneers, as to the test models, when choosing their final shape. The term comes from the English language and stands for the façade. However, test veneers are fully functional at least for some time. You can eat normal food and speak without worrying about the ceramic (or trial plastic) plates on the teeth. But they cannot bear high mechanical loads. We are sure that if you try to wear trial veneers for a few days, you will not be able to live without them. Sample plastic veneers are made by a dental technician and are based on wax casts of your teeth. The latter are made individually in the dentist's office. The technician then adjusts their shape using the model at hand, and then fully adapts the plastic veneers to the size. Step by step individually produced veneers are created, their color and shape can be optimized at any time during the "trial period".
During the installation of the trial veneer the tooth remains untouched. But if the front teeth are to be supplied with long-term ceramic veneers, they must be pre-treated. Depending on the situation, the front surface of the teeth is sanded so that the veneers could have sufficient support. This is done very carefully. With the help of X-ray image the dentist will assesses the condition of the teeth, that would be covered with ceramic plates. These teeth should be completely healthy, otherwise the installation of veneers is impossible.
Ceramic veneers are the final option for the teeth restoration. By the way, the same applies to unfastened veneers. They differ from the classical veneers in that the teeth are not yet prepared (sanding is not performed). If it is not possible to grind the right amount of tooth enamel, the dentist chooses thinner veneers so that the tooth does not look too large.
Trial veneers allow you to see the preview of the desired result and test it in everyday life. They provide information on existing types of veneers in terms of their color, shape and appearance. What is already fixed or precisely adjusted on the test veneers is ultimately used during the installation of permanent veneers, making their service more reliable.
How long do veneers serve?
If veneers are not damaged and chipped, they can serve from ten to fifteen years. But "long-term" service does not mean it is "eternal". At some point even the strongest of the veneers should be replaced.
If a veneer fell out, is broken or if you noticed a crack in it, you must first contact your dentist and agree on a reception time. If possible, contact the dentist who installed your veneers and remembers the features of your teeth.
There are several reasons why veneers crack or fall out. In order for veneers to serve long, the dentist should carefully perform his work without neglecting even the most minor manipulations. The intensive preparation is the key to durability of quality ceramic veneers. If the veneer falls out even after a scrupulous preparation, it may happen because the dentist had not glued it correctly or the tooth was under strong pressure or damaged. It is possible that the tooth itself is damaged, and maybe the veneer has served its lifetime.
Any injury can also lead to the detachment of the veneer from the tooth surface, for example, if you have accidentally bitten a metal or glass object. A stiff toothbrush or excessive acidity of toothpaste can also shorten the lifespan of your veneers. Therefore, we recommend choosing a soft toothbrush and a pH-neutral toothpaste.
Try not to lose the pieces of chipped veneer or the whole plate. The dentist may be able to glue the veneer back to the tooth if it is not damaged. Thus saving the patient's finances. If the integrity of the veneer cannot be restored or it is impossible to glue it back, a new one must be installed. The dentist can also recommend another method of color and shape restoration of the tooth.
There are two ways to perform the procedure:
1. One-step procedure:
The dentist removes the old veneers with the help of a digital scan (Cerec 3d) under local anesthesia. If the patient suffers from dental phobia, they are offered a short-term nitrous oxide anesthesia.
During the installation of veneers the dentist creates the ideal shape of the veneers. After the fitting of a veneer and approval of the patient, the tooth enamel is grinded and the dentist fixes the veneer on the tooth.
When the individual color of the tooth and the shape of the veneer are selected, it takes only 15 minutes to adjust the veneer to the tooth on the milling machine. The next step is to fit and adjust the veneer again.
If the patient feels uncomfortable, the dentist immediately changes the shape and color of the veneer.
Cement fixation. This is one of the most important steps! The ceramic plate is firmly glued to the tooth enamel after the preliminary grinding. Only this procedure guarantees stability and long-term success.
2. Two-step procedure
When the old veneer is removed, the dentist installs a temporary replacement before fixing a new veneer.
The tooth is temporary covered with a plastic plate, while the dental technician creates an individual veneer which the patient will try in 14 days. If everything is in order, the veneer is glued to the tooth enamel.
To avoid the fall out of veneers, you need to seek help only from a professional dentist, and not to neglect preventive examinations. Your dentist will carefully check the condition of your teeth and the fixation of the veneers. The patient will enjoy their veneers and beautiful smile for a long period of time with the proper care, good quality of ceramics and its professional use on a pre-treated tooth.
Veneers that do not require preparation (Non-Prep veneers)
Non-Prep veneers or veneers that do not require preparation (also known as Prepless veneers or Additionals veneers) are a proven method of teeth recovery used in the United States and gaining popularity in the field of aesthetic dentistry in Europe.
Most people who seek dentist help know perfectly well what it means to have a wide slit between the incisors, which causes discomfort: articulation disorders, food compaction, inflammation of the gums. Due to a bad tooth alignment, the pressure on the front teeth increases and they quickly abrade, the chewing surface gets worn out, chips and cracks appear. It is possible to solve all these problems thanks to veneers that do not require preparation. The dentist can install them immediately on the day of the visit.
The benefits of this new treatment method speak for themselves: the installation of the ceramic material is painless and does not require the grinding of a healthy tooth or changing its shape. With the help of Non-Prep veneers it is possible to hide all teeth defects, sparing them from further negative influence of external factors.
With Non-Prep veneers it is possible to mask not only the diastema, but also the chipped corners, cracks, and gaps. This type of veneer gives its owner a new smile without the slightest pain!
How does the treatment flow in the dentist's office?
Firstly, a complete examination of the teeth is important because veneers can only be installed on healthy teeth that are not affected by caries. After the first consultation and thorough assessment of the teeth condition, a three-dimensional modeling of the jaw is performed. Based on the three-dimensional model a wax copy is built according to the patient's wishes. This so-called mock-up is primarily used familiarize the patient with the expected result. All individual wishes of the patient who gets a chance to see his new smile with the help of the model are taken into account. If the patient is satisfied, the shaping of veneers in a dental laboratory using pressing or CAD/CAM methods is performed.
What are the risks and complications of veneer installation?
You should fear no complications. All types of veneers are made of biocompatible materials. If the patient suffers from dental phobia, they are offered to have local anesthesia before the preparation of teeth for the veneers placement. The procedure of veneers installation itself is almost painless, but due to the treatment of the teeth surface, the patient may experience some discomfort. Removal of surface enamel can also lead to increased temperature sensitivity. After the installation of veneers it is important to follow some rules: try not to eat too hard food, as veneers can break or fall out from the high pressure on the tooth. In this case, the correction or installation of new veneers will be required.
Prices: How much will the installation of veneers cost?
The veneers are quite expensive. Medical insurance companies do not cover the costs of veneers installation, and private insurance companies and additional dental insurance packages can compensate only for some of the expenses.
The prices for veneers indicated on our website reflect their approximate cost. The price depends on the brand of materials and medical, laboratory and other expenses. In addition, in most cases, additional processing is required, for example: teeth whitening, professional cleaning, orthodontic and gum correction.
Complex procedures require more dentist's time, there may be additional costs for special models and temporary plastic veneers. If you need to restore several teeth, the price drops compared to the price for the restoration of one tooth.
|Cost comparison between Germany and Eastern European regions|
|Type of veneer ||Cost per piece in Germany ||Cost per piece abroad|
|Composite veneers||From € 80 ||From € 60|
|Conventional veneers||400-900 €|| 200-300 €|
|Non-prep veneers||600-1100 €||400-500 €|
|Veneers-to-go||From 350 to 400 €||150 €|
The innovative process allows to install veneers for prices that are attractive to patients. You can quickly achieve the desired result in only one visit the dentist.
How is that possible?
The new process is based on advanced developments in the modern dental industry: the ready-made plates that are available in various shapes and sizes are used. When the patient's oral cavity is prepared, the veneers can be attached directly to the teeth. Because there is no need to process the veneers to-Go in a dental laboratory, both the time of intervention and the price of such veneers is lower.
What is the difference between the veneers to-Go and the conventional veneers?
Veneers to-Go are made of ceramics or plastic and ceramics composites (more than 80 percent of such composites are nanoceramic fillers). They have the perfect color as close to the natural teeth shade as possible. The unique production process combined with the laser coated surface, give the ceramic plates their natural appearance and excellent physical properties. Most of the cosmetic and therapeutic indications for traditional ceramic veneers also apply to the innovative veneers to-Go.
When can veneers to-Go be used?
The main indications for the installation of the veneers to-Go are anatomical deformations of the teeth, such as small or heavily worn teeth. This aesthetic procedure is fast and effective.
The preparation of the veneers requires small amount time: the dentist only slightly grinds the surface of the teeth making it possible to use veneers to-Go as a temporary solution for children. In contrast to conventional veneers, the veneers to-Go are also suitable for patients with a limited budget. In addition, the veneers to-Go can be used if you want to achieve the immediate tooth transformation in just one session. Many patients need to quickly prepare for special events, such as weddings or television interviews. Even after accidents, the veneers to-Go can be used quickly and easily.
How long do veneers to-Go serve?
Veneers to-Go are strong ceramic plates, their properties are the same as of traditional veneers.
How much do veneers cost?
You can have a deal on installation of veneers, in this case the price starts from 390 euros for one veneer.
Do I need to grind my teeth to install veneers?
In most cases, if the teeth are not too small, they do not need to be carefully sanded. Please note that some veneers, such as veneers to-Go, require no prior preparation, only in exceptional cases.
- Beautiful restored tooth surface in just one visit to the dentist's office,
- Minimally invasive intervention and minor enamel grinding,
- No stress for patients, as the intervention is superficial,
- No need to make a cast,
- Requires much less time than the veneers, that are produced in a laboratory,
- Protect the teeth enamel from further damage,
- Rather budgetary restoration of the anterior surface of the teeth, compared to other methods.
The classic prep veneers require a certain amount of preprocessing of the teeth in question, during which a thin layer is ground off. About 0.3 to 1 millimeter of substance is removed from the tooth surfaces under local anesthesia.
This represents a considerable advantage over crowns, since crowns of up to 1.5 mm have to be removed. After grinding, an impression of the teeth is made. This is sent to a dental laboratory, where a dental technician produces the veneers individually. Until the final veneers are in place, temporary caps are put on to protect them. The finished veneers are then glued to the tooth surface by the dentist using a special adhesive. The installation takes about half an hour.
When using non-prep veneers, which are very thin with a material thickness of only about 0.3 millimeters, a preparation, that is, a grinding of the teeth, is not necessary.
Non-prep veneers are attached to the tooth surfaces without prior grinding and wearing protective caps. Accordingly, non-prep veneers are ideal if the tooth structure should be corrected as quickly and painlessly as possible. The very well-known Lumineers® are a form of non-prep veneers, more precisely it is a brand.
In contrast to prep veneers, "non-preps" can also be attached to existing plastic fillings, dental bridges or ceramic dental crowns.
Statistical evaluation of the results
The statistical evaluation was carried out together with several dental clinics. The durability of the veneers is examined.
The following is used as a yardstick for durability:
- the loss rate - d. H. what percentage of the veneers were still present, i.e. in situ. It does not matter whether complications such as root canal treatment, cementation, etc. had occurred. The time was defined as the period between the cementing and the last control appointment, or in the case of loss until the previous control appointment, as documented in the patient record.
- the success rate - i.e. what percentage of the veneers were still present and at the same time showed no complications (losses + possibly necessary after-treatments).
The examination time for veneer restorations averaged 38.6 months (min: 6.2 months; max: 84.7 months).
90% of all eligible patients could be included in this study. These were functionally unremarkable patients with caries-free, adequately cared for teeth.
The ceramic restorations were distributed to female and male patients. This corresponds to a share of 56.76% female and 44.24% male. The ages of the patients ranged from 20 to 73 years. The average was 49.82 years. The standard deviation in age is 11.85 years.
The patients were assigned to groups of 10 years according to their age in order to structure the distribution of the veneers at individual age levels. After that, the focus of the age distribution was on a third in the age group 40-49 years. 50 and over 50 were slightly more patients.
The analysis showed that there are two periods in which the loss rate is high in relation to the rest of the time. A total of approximately 10% losses were recorded in the examination after 36 months. There were also losses in the first 21 months occurred, another was found after about 48 months. The following waste can therefore be described:
After 13.31 months the success rate drops from 100% to 98.89%, after 15.48 months to 97.7%, after 19.51 months to 96.46%, after 20.69 months to 95.12%, to drop to 90.99% after 47.93 months. Four of the losses mentioned are due to ceramic fractures and one loss was caused by total tooth loss in the sense of an extraction.
