Volumetric Changes and Graft Stability in Lateral Window Sinus Augmentation: A Prospective Clinical Trial

University of Oklahoma19 enrolled

Overview

The purpose of this study is to evaluate the stability and volumetric changes of the grafting materials used for lateral window sinus augmentation. In addition, different variables known to affect bone stability and remodeling with regard to the augmentation procedure will be evaluated. Similarly, implant placement will be performed and results will be evaluated after a period of six months.

This will be a prospective clinical study evaluating the stability and volumetric change of two grafting materials used in lateral window sinus augmentation procedure (anorganic bovine bone xenograft alone compared to a mixture of allograft and anorganic bovine bone xenograft). Participants will have the same surgical treatment of the lateral window sinus augmentation procedure. Participants will have a simultaneous implant placement at the time of sinus augmentation procedure or a delayed implant placement based on the stability of the implant evaluation. Cone beam computed tomography (CBCT) will be used to evaluate the volumetric changes between two groups of graft material in sinus augmentation procedure at three time points: pre-operatively, two weeks post-operation and six months post-operation. Biopsies will be harvested after six months for histological and histomorphometric analysis.

Outcomes

Primary Outcomes

Graft volumetric stability change

CBCT will be the primary tool to evaluate the volumetric stability of the graft material used in the sinus augmentation procedure

Time frame: CBCT taken at 2 weeks after the procedure and 6 months after the procedure of sinus augmentation to assess the volumetric changes of the graft material

Secondary Outcomes

Histomorphometric analysis

Identify histological differences between two groups of graft material in sinus augmentation procedure

Time frame: After 6 months of sinus augmentation procedure when the implant is placed
