PROVISIONAL AND DEFINITIVE PROSTHESES FOLLOWING SINUS LIFT AND AUGMENTATION PROCEDURES

Abstract
Sinus lift and augmentation procedures with simultaneous insertion of cylindrical root form implants can be used to treat the atrophic posterior maxilla. The long-term use of a second stage provisional prosthesis is emphasized. The recommended metal-reinforced acrylic resin provisional restoration allows treatment and/or removal of a failing implant and progressive loading before fabrication of the definitive prosthesis. Modifications in prosthesis fabrication after sinus lift surgery and augmentation procedures are discussed.
