Sinus floor elevation is widely considered as one of the most reliable and predictable procedures for augmenting posterior maxillary bone volume before implant placement. The lateral window technique is often described as the gold standard, especially when dealing with limited residual bone height. Traditionally, severe vertical defects in the posterior maxilla required a two-stage approach: first elevating the sinus membrane with biomaterial, followed by a second surgery for implant placement. This article introduces an innovative approach to the lateral sinus lift procedure, enabling simultaneous implant placement in sites with less than 5 mm of remaining bone height. This original one-stage surgical approach is interesting because it does not involve grafting of any biomaterial into the sinus. Its main objectives are to enhance safety and predictability while reducing the risk of post-operative infections. However, it's essential to emphasize that achieving an ideal implant position with adequate primary stability is crucial for its viability.
