Everything depends on severity of osteoporosis and medical therapy that’s been assigned. Osteoporosis makes bones thicker and more fragile. Besides, inner bone trabecules also lose in volume. These factors are crucial, when it comes to bone loading. Becoming fragile, bone structures destroy and form hollow spaces. These changes are also typical of jaw bones, but destruction process can take years due to demineralization.
In order to define the severity of osteoporosis, doctors use DEXA method (osteodensimetry). They measure the diameter of wrist bones. However, it should be noted that DEXA values cannot show for sure whether destructive process in jaw bones has started.
If a patient wants to go through implantation, 3D X-ray scanning should be performed. Thanks to special software, mineral contents of jaw bones can be evaluated. If moderate osteoporosis has been revealed, a dentist will use several methods allowing him to boost bone thickness around the implant.
When preparing jaw bone to implantation, a dentist will drill it accurately according to the planned length of the implant. When the channel is widened with dental borer, the dentist leaves it pretty narrow to fix the implant tightly and fix it forever. The implant is screwed in the small channel that works by screw principle – it pushes extra bone tissue out which allows increasing thickness of bone around the implant.
During preparation process, a dentist makes a small incision for the entire maximal length of implant. Using conic instruments with rounded end, a dentists pushes bone. If the instrument with the right diameter is used, a hole that’s ideal for the implant is made. In this case, bone tissue is not removed – it’s pushed outside. This method increases bone density and helps to avoid its destruction.
Mineral bone filler material can be injected into the inner wall of drilled channel and moved outside when the implant is being screwed. There are different paste-like materials that harden after being injected into the cavity. Depending on manufacturer, various forms and types of products are available. During many years, therapists and orthopedists have been using bisphosphonates to treat osteoporosis. This remedy prevents excessive loss of bone mass. Unfortunately, bisphosphonates also decrease bone regeneration, which leads to disorders in recovery and various complications after orthodontic surgeries. When bisphosphonate therapy is over, a surgeon injects products or uses them orally. The dosage is defined by dentist.
Neither light, nor severe form of metabolic osteoporosis is usually not a contraindication to dental implantation. In every individual case, dentist decides upon this method after diagnostics and examination. It’s crucial whether bisphosphonates were used for osteoporosis therapy, because use of this product can be a contraindication to implantation.
