This study aimed to analyze the effectiveness of virtually designed polyetherâ?Âether ketone (PEEK) sheets to delineate and maintains the threeâ?Âdimensional patient's maxillary alveolar ridge.
Materials and methods: Fourteen patients (34 implants) with severely atrophied anterior maxillary alveolar ridges underwent rehabilitation using customâ?Âmade CAD/CAM PEEK sheets acting as a containment system for interpositional mix of particulate autogenous and xenogeneic bone graft, fixed by monoâ?Âcortical screws. Radiographic Assessment included measurements of linear changes in the vertical and horizontal dimensions on crossâ?Âsectional 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 Pâ?Âvalue of (.0001). The customized sheets were removed 6 months postoperative with the successful placement of dental implants.
Conclusion: The virtual planning of threeâ?Âdimensional maxillary alveolar ridge augmentation utilizing patientâ?Âspecific PEEK sheets deemed successful to restore the deficient ridge and to accommodate suitable size dental implants.
