Abstract

Transcrestal sinus floor elevation (tSFE) is a useful method for vertical bone augmentation in the posterior maxilla at the time of implant placement. However, this is a blind surgical technique with a risk of perforating the Schneiderian membrane. In this article, we present a simple technique to perform tSFEs using ridge spreaders. With this technique, the tSFE is performed in a slow and controlled manner without the entry of instruments into the maxillary sinus. Furthermore, many clinicians may find they already have the necessary surgical tools within their armamentarium. This precludes the need for rotary drills that spin at high revolutions per minute in the sinus cavity or osteotomes which may result in an uncomfortable patient experience. In order to fully exemplify its clinical utility in performing successful tSFE without membrane perforation, we present this surgical technique in a case with limited residual bone height and a steeply oblique sinus floor.
