Crestal Window Sinus Lift

93 Rating(s).

Posted on By Ahmad Hawasli In Sinus Augmentation

A healthy, non-smoking 53-year-old male patient presented with a chief
complaint of non-restorable carious roots # 12,13,15 and edentulous area # 14. Radiographic
evaluation revealed maxillary sinus pneumatization with residual alveolar bone height of 2.8-
3.2 mm. Treatment comprised extraction of remaining roots, sinus elevation and implant
placement. After roots extraction and flap elevation, a crestal bony window was outlined and
prepared using Piezosurgery. The sinus membrane with the attached bone block were elevated
by osteotomes. Freeze Dried Bone Allograft was packed into the created osteotomy and
covered with collagen membrane. Six months post operatively, the radiographic evaluation
revealed alveolar bone height of 7-8 mm. Implants were restored four months after

English please?.


In this case, what do you feel was the advantage of the crestal windo over the lateral window? Dr. Salama


Thank you for the question, the lateral sinus lift remains the basic approach, however; by this technique the advantages were avoiding superior alveolar artery injury and having autogenous bone block in the sinus instead of Xengrafts.


Nice work,well done!
