| Abstract | ||||
| Aim: To evaluate the osteogenic potential of allogenic bone block grafts for horizontal alveolar ridge augmentation in the bounded anterior maxillary region, both radiologically and histologically. Materials & Methods: Study was conducted as a case series on 10 Medically free patients, which were selected from the outpatient clinics of the Oral and Maxillofacial surgery departments, faculty of dentistry, Ain Shams University, and Future University. These patients had horizontal defects in the alveolar ridge. These defects were located in the anterior maxillary region. The residual ridge width was ≤ 4mm and they were seeking implant treatment for the restoration of missing teeth. Allogenic bone blocks were used for augmentation of the bone defect in the maxillary region. The results of bone augmentation were assessed radiographically using cone beam computerized tomography (CBCT) by comparing bone width preoperatively and postoperatively after 6 months of follow up at crestal, middle and apical regions. The volume of bone gain was assessed by superimposition of 3D bone models obtained from CBCT. Histologic analysis was done on bone biopsies obtained by trephination drilling at the site of gained bone at the time of implant placement. Results: This study results showed significant increases in bone width and bone volume after 6 months of follow up. Histologic analysis revealed new bone formation with minimal fibrous tissue formation. Conclusion: Allogenic bone blocks used for bone augmentation produced a significant increase in bone width and bone volume and can be used as effective grafting material for bone augmentation in maxillary region. | ||||
