SMART-LIFT: una nuova procedura minimamente invasiva per la elevazione del pavimento del seno mascellare.

Introduction. The elevation of maxillary sinus floor with a crestal approach is a clinically consolidated surgical procedure. Implants positioned in augmented sinuses show a long-term success rate similar to implants positioned in native bone. Clinical aspects. Unfortunately conventional surgical techniques are affected by important limitations, such as poor control of the working depth of surgical instruments and excessive trauma of residual osseous crest. These limitations could increase the risk of perforating the sinus membrane or increasing post-surgical adverse events affecting ear and vestibule. Aim of work. The aim of this study is to describe a new method for sinus floor elevation with a crestal approach, developed in order to overcome the limitations of conventional techniques. Case report. The operative steps and a case report are illustrated in details.
