Radiographic Changes in the Maxillary Sinus Following Closed Sinus Augmentation

The University of Texas Health Science Center at San Antonio25 enrolled

Overview

A closed sinus augmentation is performed for dental implant placement.

Patients who are diagnosed as needing sinus augmentation by a closed approach for dental implant placement will be recruited. A cone beam computed tomography (CBCT) study is the standard of care prior to dental implant placement. However, following closed sinus augmentation nothing is known as to the extent of augmentation in the medial to lateral (cross-sectional) dimension. Patients will have a low volume CBCT taken immediately postsurgically, and again at the six-month postoperative visit to determine the dimensional changes in the augmentation. These images will be compared to standard periapical radiographs at the same time points.

Time frame: Baseline immediately postoperatively and at 6 months

Dimensional Change in augmentation at 12mm

Determine the morphologic changes to maxillary sinus anatomy three dimensionally when a closed sinus augmentation is performed for dental implant placement at 12 mm from alveolar crest.

Time frame: Baseline immediately postoperatively and at 6 months
