Autogenous bone ring augmentation and simultaneous implant placement in the atrophic posterior maxilla: A case report.

Introduction And Importance: Restoring lost teeth in the posterior atrophic maxilla presents a significant challenge due to insufficient bone volume for implant placement. Simultaneous implant placement during lateral sinus lift is often considered, but the decision is typically based on the amount of existing bone. The aim of this study was to investigate the feasibility of simultaneous implant placement and maxillary sinus floor augmentation in the atrophic posterior maxilla using autogenous bone ring.
