Subperiosteal dental implantation is a dental procedure that involves the placement of dental implants beneath the periosteum, which is the dense connective tissue that covers and nourishes the bones. It is an alternative to traditional endosteal implants, which are inserted directly into the jawbone.
During subperiosteal dental implantation, a custom-made metal framework or implant is created to fit the contours of the patient's jawbone. This framework is designed to sit on top of the jawbone, just beneath the periosteum. The implant is then surgically placed on the jawbone, and the soft tissues are repositioned to cover and support the implant.
Subperiosteal dental implantation is often recommended for patients who have insufficient bone density or height to support traditional endosteal implants. It can be a suitable option for patients with bone loss due to periodontal disease, trauma, or long-term denture use.
The advantages of subperiosteal implantation include reduced surgical invasiveness and the ability to avoid bone grafting procedures. Additionally, this technique allows for the placement of implants in areas where there is limited bone volume, expanding the scope of patients who can benefit from dental implantation.
However, subperiosteal dental implantation is generally a more complex procedure compared to endosteal implantation, and it requires careful planning and customization. The success of subperiosteal implants depends on factors such as precise fit, adequate bone support, and proper integration with the surrounding tissues.
Overall, subperiosteal dental implantation offers a viable solution for patients with inadequate bone structure to support traditional implants, providing the opportunity to restore dental function and aesthetics.
