Rehabilitation of Right Posterior Maxillary Arch with Tilted Implant Placement to Bypass Maxillary Sinus with Help of Implant Supported Fixed Prosthesis: A Case Report

Abstract

The early loss of maxillary posterior teeth leads to maxillary sinus pneumatisation, reducing the alveolar ridge height, and thus posing challenge for implant placement. Owing to mechanical and anatomic difficulties, implant treatment in the atrophic maxilla represents a cumbersome task. The maxillary sinus floor augmentation procedure is still not universally accepted because of its complexity and its unpredictability. This condition may be treated with an elevation of the maxillary sinus floor, which is usually accomplished by lateral or transcrestal approach to the antrum. As an alternative to these augmentation procedures, a more conservative treatment option would be to either place short implants or to bypass the sinus floor. This case report emphasizes on maxillary sinus by pass with tilted implants in close proximity to the sinus wall, thus, avoiding sinus floor elevation & bone grafting procedures.
