A novel trephine design for sinus lift lateral approach. Case report

Various techniques are described in the literature, either by crestal or lateral approach. Sinus augmentation has a high percentage of success, but presents a number of intraoperative and postoperative complications. The most frequent complication is the Schneiderian membrane perforation with a percentage of perforations between 11% and 56% according to authors. The aim of this study is to describe another membrane approach technique for the sinus lateral wall osteotomy that minimizes the risk of Schneiderian membrane perforation. We present a case of a 50 year old patient attended the University Dental Clinic (UDC) of International University of Catalonia for implant and crown treatment du…
