Abstract

Abstract: Background: This study aimed to analyze the effectiveness of virtually designed polyether‐ether ketone (PEEK) sheets to delineate and maintains the three‐dimensional patient's maxillary alveolar ridge. Materials and methods: Fourteen patients (34 implants) with severely atrophied anterior maxillary alveolar ridges underwent rehabilitation using custom‐made CAD/CAM PEEK sheets acting as a containment system for interpositional mix of particulate autogenous and xenogeneic bone graft, fixed by mono‐cortical screws. Radiographic Assessment included measurements of linear changes in the vertical and horizontal dimensions on cross‐sectional cuts of computed tomography (CBCT) using special software. Results: Wound healing was uneventful for all the patients except one patient that showed wound break down 2 weeks postoperatively, which did not affect the outcome of the procedure. CBCT scans were interpreted to compare the quantity of both vertical and horizontal bone preoperatively and 6 months postoperatively. Statistical analyses demonstrated a significant difference between the results of both time intervals, with a mean vertical and horizontal bone gain was 3.47 mm(±1.46) and 3.42 (±1.1) with a P ‐value of (.0001). The customized sheets were removed 6 months postoperative with the successful placement of dental implants. Conclusion: The virtual planning of three‐dimensional maxillary alveolar ridge augmentation utilizing patient‐specific PEEK sheets deemed successful to restore the deficient ridge and to accommodate suitable size dental implants.
