Piezosurgical Buccal Plate Repositioning Technique for Horizontal Alveolar Ridge Augmentation

Study Overview
=================
Brief Summary
-----------------
Achieving prosthetically driven implant placement is a highly predictable treatment modality with reliable long-term results. Different surgical procedures have been used as a solution for reconstructing of the alveolar ridge with deficient volume. In the present study we demonstrate a modified alveolar ridge split technique for horizontal alveolar ridge augmentation (buccal plate repositioning technique) using the piezotome surgery. Evaluation of the effect of silica-calcium phosphate nanocomposite (SCPC) graft material versus demineralized freeze dried bone allograft (DFBA) in horizontal alveolar ridge augmentation before implant insertion will be performed.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| change in alveolar ridge width | All patients will receive a CBCT scan; immediately after surgery and at 6 months post-operatively. The images will be analyzed using OnDemand3D software (Cybermed Inc) CBCT analyzing software and compared to the pre-operative scan for alveolar ridge width evaluation. | at baseline and 6 months |
