Objective: This case report describes a novel technique that combines a lateral window sinus lift with simultaneous lateral ridge augmentation using an autogenous block graft. Materials and methods: A patient presented with a left maxillary edentulous ridge deficient both vertically, due a pneumatized left maxillary sinus, and horizontally. A lateral window sinus lift was completed, and the window of the sinus wall was used as an autogenous block graft for simultaneous ridge augmentation. The patient was allowed to heal for six months, and the site was re-entered to place three implants. The implants were allowed to osseointegrate for three months, and were subsequently restored with screw-retained restorations. Results: An increase in ridge width from approximately 3 mm to 7 mm was achieved at the site of the autogenous block graft, and created an edentulous ridge suitable for dental implant placement in a prosthetically driven position. Conclusion: This novel technique avoids complications and patient morbidity of an additional donor site for an autogenous block graft, and should be considered when ridge augmentation is needed adjacent to a lateral window sinus lift.
