Secured sinus augmentation with piezosurgical techniques A report of 3 cases

The sinus graft procedure has become a standard treatment modality in augmenting pneumatized sinuses for implant therapy in the posterior maxillae. Perforation of the Schneiderian membrane is one of the major complications during sinus lift procedures resulting in unfavourable graft remodelling and secondary complications such as bleeding and sinus infections . In the present case series, piezo surgical techniques were applied for sinus augmentation in three patients: Case 1 and 2 received a sinus graft with simultaneous implant placement while Case 3 received sinus graft alone for future implant placement. The immediate post surgical review showed minimal inflammatory reaction and 6 weeks review showed excellent wound healing and optimal patient comfort. 6 month post-operative review revealed favourable bone fill and successful osseointegration in the implant sites.
