[Elimination of Schneider's membrane defects arising during sinus lifting operation]

During the operation of sinus lifting and occurrence of Schneider's membrane defect in the size no more than 3 mm the technique of its elimination is offered. Anatomic features of structure of maxilla sinus and error of surgical technics can lead to intraoperative rupture of a Schneider's membrane. At the size of defect no more than 3 mm are recommended to separate a membrane on all perimeter of the bottom third of sinus and then to lift it up until edges of the damaged mucous membrane will block, <> against each other forming a fold, thereby closing defect. The offered method allows to spend successfully sinus lifting as with delayed (in 6 months), and with direct implantation.
