Piezoelectric internal sinus elevation (PISE) technique: a new method for internal sinus elevation.

This article reports the surgical procedure of a transalveolar approach for sinus floor elevation using piezoelectric surgery without a mallet, called piezoelectric internal sinus elevation (PISE) technique. PISE is the modified technique of the osteotome-mediated sinus floor elevation. Osteotome-mediated sinus floor elevation uses a mallet to break the sinus floor and to push sinus membrane up. Using this technique might possibly bring positional vertigo to the patient. PISE technique does not use a mallet during the procedure to break the sinus floor and to elevate the sinus membrane; therefore, it can reduce the possibility of postoperative positional vertigo.
