| Abstract | ||
| Background: Alveolar bone deficiency is one of most common problems encountered with oral rehabilitation. Many bone augmentation techniques have been documented, one of them is augmentation by bone grafting and barrier membranes, ceramic membrane proved efficiency in guided bone regeneration duo to enhanced properties. Aim of this study: Evaluation of bone surface area under perforated ceramic membrane in relation to non perforated ceramic membrane. Materials and methods: 14 mongorel dogs divided in to two equal groups, study group used bone graft, cortical perforation and perforated ceramic membrane, control group used bone graft, cortical perforation and non perforated ceramic membrane, follow up for 12 weeks and scarification was done retrieving ceramic mebrane with samples of new bone which histologically prepared for histomorphometric analysis. Results: By histological evaluation more cellularity and vascularity, better trabecular arrangement and lesser granulation tissues were noted under perforated ceramic group. By histomorphometric analysis statistically significant at p ≤ 0.05 and higher bone surface area with mean value of 40.09 ± 3.50 associated with perforated group in comparison with mean value of 19.92 ± 3.63 associated with occlusive group. Conclusion: Perforated ceramic membrane is comparable to occlusive one in terms of higher bone surface area, reduced granulation tissues and favorable blood supply. | ||
