• Purpose: The aim of the present study was to evaluate the sinus membrane perforations that occurred during a sinus lift procedure using the ultrasound technique, and to evaluate the bone gain obtained. Materials and methods:

  In 21 patients, 26 sinus lifts were performed using ultrasound and filled with bone graft material. The bone height and the bone gain obtained were observed in postoperative orthopantomographs, correcting for previous distortion.

  Results: Of the 26 maxillary sinus lifts, 4 Schneiderian membrane perforations were observed. The average bone height prior to the intervention was 3.5 mm (scale 0.6- 8.7 mm ) and the average postsurgical bone height was 10.8 mm (scale 7.5- 15.6 mm). An average bone gain of 7.2 mm was observed (range 2.5- 11.7 mm). Conclusions:

  Based on the results of this study, during ultrasound sinus lift, few Schneiderian membrane perforations occurred and all were small .
