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