All surgical techniques to elevate the maxillary sinus present the possibility of perforating the Schneiderian membrane. The complication can occur during osteotomy which performed with burs. It can also occur during the elevation of Schneiderian membrane using manual elevators.
Piezoelectric bone window osteotomy cuts bone without damaging the soft tissue. Piezoelectric membrane elevation separates the Schneiderian membrane without perforations.
The elevation of Schneiderian membrane from the sinus floor is performed using both piezoelectric elevators and the force of a physiologic solution subjected to piezoelectric cavitation.
