The quality of the residual posterior maxilla in the post extraction phase concurrently with the sinus antrum pneumatization most of the time require a bone augmentation procedure in order to accommodate implant-supported prosthesis. In both the maxilla and mandible, the posterior maxilla is the most frequent site where an implant placement procedure is usually accompanied by bone augmentation. This chapter presents a case that describes severe crestal bone resorption concurrent with sinus floor pneumatization. In the case, the regeneration of the defective ridge is combined concurrently with sinus floor augmentation via a lateral window approach. The chapter presents another case demonstrating an unavoidable previous socket site of the upper first molar and the sub-antral area of the maxillary sinus. This case was presented with a history of multiple failed sinus augmentation/implant placement episodes. The Schneiderian membrane perforation has been considered as the most frequent complication in sinus augmentation procedures.
