The loss of teeth in the posterior maxillary area is a real handicap for patients, which significantly affects their quality of life. This study aims to perform an exhaustive multidisciplinary analysis of bone reconstruction at this level using alloplastic osteoinductive material, followed by dental implant treatment. The results of the study show a 92.7% rate of implant integration and a 35% rate of replacement of the augmentation material with new bone after six months. The recovery of the lost functions is complete, and after a maximum length of time of 18 days, with a mean of 4.36 days, patients no longer perceive the reconstruction as a foreign body, which means a real improvement in their quality of life.
