The sinus lift procedure aims to create increased bone volume in the maxillary sinus in order to enable installation of dental implants in the. The basic approach to the sinus (Caldwell-Luc operation) involves an osteotomy performed on the lateral maxillary wall, elevation of the sinus membrane, and placement of bone graft material. For more than 30 years the maxillary sinus augmentation graft has been a mainstay of The primary indication for sinus graft surgery is the planned implant.
