| Abstract | ||
| Background: This study was designed to evaluate bone augmentation of posterior alveolar mandibular ridge using 3D computer guided ceramic Sheets as a membrane in GBR . Methods: Seven patients were included in the present study. Preoperative clinical evaluation, and CBCT scan for ridge evaluation and planning, all patient clinically suffering from severed resorbed posterior alveolar ridge of the mandible. Measuring height and width of right and left residual alveolar ridge was performed in CBCT software viewer base on this digital model 3D zirconia sheet was designed and plan on patient CBCT then milled on CAD/ CAM 5 axis machine to the desired macroscopic shape. After surgery, clinical evaluations were done at intervals of 2 weeks, first month, 3rd and 6th month and directed toward the observation of the healing process, sings of inflammation, infection soft tissue dehiscence, Zr exposure or any complications of wound. 2nd surgical intervention to remove the screws and Zr sheet and CBCT evaluation to measuring alveolar ridge on both sides. Results: Results of the current showing that customized Zr sheet can use successfully to obtain vertical and horizontal bone augmentation well compatible with soft tissue without exposure. Conclusion: Customized Zr sheet act as a perfect barrier and space maintaining in GBR procedures with precise fit. Good soft tissue acceptance to Zirconia. Customized Zr sheet reduce chairing time and amount of graft. More predictable results can obtained by using xenograft under Zr sheet. | ||
