| Abstract | ||||
| Purpose: The aim of this study was evaluating and compare the clinical outcome of bone block ridge augmentation using two flap designs approach, crestal incision and Kazanjian vestibuloplsty. Materials and Methods: 20 patients with age range 35- 55 years will be included in this study; all patients selected for this study require bone augmentation procedures because of severe alveolar ridge atrophy in posterior mandible with standing anterior teeth. Patients will be divided randomly in to two groups of 10 patients. Group A will be scheduled for ridge augmentation using Kazanjian vestibuloplasty incision approach and group B will be scheduled for ridge augmentation using crystal incision. Results: This study demonstrated that the use of Kazanjian vestibuloplasty resulted in significant increases in ridge width and height. In group A the amount of bone height gained was 2.25 ± 1.31 mm (P < 0.001) and bone width gain was 2.3 ± 1.49 mm (P < 0.002), while in group B the amount of bone height gained was 0.75 ± 0.97 mm (P < 0.001) and bone width gain was 0.45 ± 0.55 mm (P < 0.002). Conclusion: In posterior mandible reconstruction, bone grafts increase the number, length, and diameter of implants that can be placed. The use of Kazanjian vestibuloplasty is better than crestal incision as an approach during ridge augmentationn using Nanobone block. Recommendation: More attention to detail and meticulous technique may prevent the progression of complications to Nanbone block graft failures. | ||||
