The application of Dental implants for the prosthetic rehabilitation of missing teeth has provided a multitude of treatment options for patients. Loss of teeth in posterior maxillary area can lead to adverse consequences. Maxillary sinus pneumatisation is one of these that precludes placement of implants due to anatomical constraints. In this anatomical situation, it can be very difficult to obtain effective primary stability. Maxillary sinus augmentation has been shown to be a predictable method to increase posterior maxillary bone height, and allow placing dental implants when the residual alveolar ridge is deficient in bone volume. Following post extraction resorption amounting to deficient bone volume in posterior maxilla, many approaches have been described to augment the residual bone ridge by ensuring sinus membrane elevation up to 5mm without tearing it. Boyne and James first described the sinus lift technique based on a modification of the Caldwell-Luc sinus revision, involving a lateral approach to the sinus that allows a remarkable bone augumentation upto >10mm even in atrophic ridges.
