Overview
Brief Summary
Evaluation of computer guided placement of Zygomatic implants utilizing intra sinus versus extra sinus surgical approach for the reconstruction of atrophic maxilla. The expected benefit from the current study is to select the most suitable approach for Zygomatic implant placement with the least postoperative complications
Detailed Description
During the last ten years, there has been an increase in the number of edentulous patients looking for and seeking out rehabilitation. Formerly, individuals with edentulous maxilla and mandibles were rehabilitated with removable complete dentures, but it was associated with poor patients' satisfaction. Alveolar bone atrophy results from loss of bony support due to the physiological process that naturally takes place after tooth loss, especially in the upper arch. Due to its shape and structure, the maxilla is an extremely challenging arch to reconstruct with dental implants. Oral and Maxillofacial surgeons began utilizing alternative methods to replace missing teeth with osseointegrated dental implants in atrophic maxilla. As a result, different methods were developed for handling of this issue, including tilted implants, sinus elevation, the use of Pterygoid implants, the use of short implants and Zygomatic implants.
