Minimally invasive technique for transcrestal sinus floor elevation: A case report
Trombelli, Leonardo / Minenna, Pasquale / Franceschetti, Giovanni / Minenna, Luigi / Itro, Angelo / Farina, Roberto
The present report describes a minimally invasive technique for transcrestal sinus floor elevation, namely the Smart Lift technique, which is based on the controlled use of drills and osteotomes. The rationale of this technique is to provide predictable vertical bone augmentation into the sinus cavity by (1) using the existing residual bone as a viable graft and (2) limiting the incidence of membrane perforation and postsurgery morbidity. Surgical steps of the procedure are thoroughly illustrated by means of a paradigmatic case. The Smart Lift procedure was compatible with sinus floor elevation and implant stability for up to 1 year following surgery. No complications occurred during or after surgery. On periapical radiographs, a radiopaque area corresponding to the augmented sinus floor was present above the apical portion of the implant.
