Many patients have been told that they are not candidates for dental implants due to lack of bone in the upper jaw. These patients can benefit from a new implant developed by Professor Per Ingvar Brånemark. This latest implant provides an excellent alternative to bone grafting procedures for the severely resorbed jaw bone with minimal surgical trauma and maximum oral function.
The incidence of implant loss in the severely resorbed posterior upper jaw is about 15% without the benefit of sinus grafting. Current modalities for reducing implant loss in these areas involves different types of grafting procedures. These grafts vary extensively and include everything from using allografts, alloplasts, and xenograft materials to harvesting bone from the patients chin, calvaria, tibia and hip. Although all have had various degrees of success, there is a significant lack of consensus in all aspects related to procedures of grafting for the severely resorbed posterior upper jaw.
While alternative grafting procedures were being explored worldwide, Professor Brånemark began reexamining the basics of anatomic cranio-facial and orthopaedic reconstruction. The fundamental question that needed to be answered was "How can we -in a similar, safer, and highly predictable manner - restore function to those patients who have so severely resorbed jaws that standard implants were bound to provide unacceptable results?"
Professor Brånemark then conducted extensive studies evaluating craniofacial bone and its load bearing capacity. It was found that the Os Zygomaticus, the zygomatic bone, consistently demonstrated dense quality and acceptable bone volume. If nature could provide the dense type of bone we already know offers the most predictable anchorage (osseointegration), wouldnt it be a significant improvement to use this bone compared to conducting extensive grafting procedures?
Brånemark and his team treated the first patient with zygomaticus implants in 1989. In a follow up study of implants in function up to ten years, 97 implants were evaluated. The cumulative success rates for this new implant was 96.8%.
Pi Dental Center is now pleased to provide Zygomatic implant therapy for patients with severely resorbed upper jaws. We would be very happy to evaluate any individual who has substantial bone loss and may be a candidate for the zygomaticus implant treatment. Please don't hesitate to call us with any questions you may have about the zygomaticus implant or about referring your family and friends to Pi Dental Center for consultation or treatment.
