Abstract
Objective: The aim of the present study was to compare the clinical outcome and radiographic bone changes of augmented ridge utilizing synthetic Nanobone block versus allograft bone block. Investigate histologically, the success of synthetic Nanobone block versus allograft bone block for augmentation approach. Assess and compare the clinical success of the dental implants which will be inserted in the augmented localized atrophied ridges by bone grafting material versus bone substitute after one year. 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, either unilateral or bilateral with standing anterior teeth. Patients will be divided randomly in to two groups of 10 patients. Group A will be scheduled for ridge augmentation by using Nanobone block and group B will be scheduled for ridge augmentation by Fisiograft bone block. Tiologic implant system placed in both group after six months. Results: This study demonstrated that the use of Nanobone block resulted in significant increases in ridge width and height, facilitating implant placement in area previously judged to be narrow. 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 Nano bone block grafts allows the placement of implants of standard length and diameter, thereby improving long-term prognosis of the implant-supported reconstruction. Recommendation: More attention to detail and meticulous technique may prevent the progression of complications to Nanbone block graft failures.
