ABSTRACT Background: For single‐tooth implant replacement in the posterior maxilla, it is often necessary to do an augmentation of the alveolar process because of post‐extraction resorption and include part of the maxillary sinus. Purpose: The purpose of this study is to present a technique for a local sinus lift with autogenous bone in a one‐stage procedure. Additionally, volume changes of the grafted area were evaluated radiographically up to 2 years. Materials and Methods: Twenty patients, 12 female and 8 males, were included in the study. Single‐tooth replacement was made in the second premolar area in 7 cases and in the molar area in 13 cases. Local sinus lift and implant installation were made simultaneously. Abutment connection was made after 6 months of healing. Results: Two years of clinical and radiographic follow‐ups have been made in all patients. The survival rate was 100%. The residual bone volume in the actual area was 2–5 mm preoperatively, after sinus lifting in mean 13 mm, after 1 year in mean 11.4 mm, and 2 years postoperatively in mean 10.6 mm. Conclusions: Local sinus lift with simultaneous bone augmentation and single‐tooth replacement in the posterior maxilla is a predictable method although a certain bone volume reduction around the implant was evident at the 2‐year follow‐up.
