Minimally Invasive Transalveolar Sinus Augmentation: An Answer to Sinus Conundrum

Abstract

Dental implants have become the routine option for replacement of missing teeth, but it is challenging to place implants in the posterior maxilla due to inadequate bone dimensions and pneumatization of the maxillary sinus. Several techniques have been introduced over the years for sinus augmentation and bone grafting; both lateral and crestal approaches to sinus lift have been used with good results. In recent times, a minimally invasive technique has been used as a modification of crestal approach to sinus augmentation called minimally invasive technique sinus augmentation (MITSA). This method utilizes the calcium phosphosilicate putty for hydraulic sinus membrane elevation along with osseodensification drills. MITSA has simplified the sinus lift technique with predictable good results.
