Use of Implants in the Pterygoid Region for Prosthodontic Treatment

ACP Article Screenshot ThumbnailPlacement of implants in the posterior maxilla is challenging due to the quality and quantity of available native bone and the presence of the maxillary sinus. Common methods to mitigate implant  placement in the posterior maxilla are direct sinus membrane elevation (“lateral window sinus lift”) and indirect sinus membrane elevation (“internal sinus lift”). These methods provide a good survival rate for dental implants, according to studies in the scientific literature. However, they have a number of
disadvantages that preclude some patients from being able to benefit from implant therapy. These disadvantages include higher surgical morbidity, need for bone grafting, and increased treatment cost and time. Additionally, they do not allow immediate loading/function in edentulous patients. READ STATEMENT
