Sinus Lift Procedures in Implantology

Sinus lift surgery is a dental procedure used to increase bone height in the upper jaw (posterior maxilla) by placing bone graft material into the maxillary sinus. It is mainly performed when bone loss and sinus expansion (pneumatization) make dental implant placement difficult.There are two main techniques: the lateral window (external) approach, which is more invasive but allows greater bone augmentation, and the transalveolar (internal) approach, which is less invasive and used for smaller bone gains. The procedure can be done either with immediate implant placement or delayed implant placement after bone formation.Sinus lift improves implant success in the atrophic maxilla, but requires careful treatment planning and modern techniques help achieve predictable functional and aesthetic outcomes in implant dentistry.
