| Abstract | ||
| Aim: This study aimed to evaluate the efficacy of the collagen membrane versus Vascularized inter-positional Periosteal connective tissue flap (VIP-CT) in Guided bone regeneration in horizontal ridge augmentation in the aesthetic zone in terms of radiographic outcome Methodology: Twenty-four patients with horizontal bone defect were randomly allocated equally into two groups; the control group: (group I) underwent bone graft augmentation (autograft and xenograft) with collagen membrane fixed with suture or tacks, whereas the other group underwent bone graft augmentation, VIP-CT flap was performed and fixed over graft with sutures. Each patient was assessed pre operatively and 6 months post operatively radiographically using cone beam computed tomography (CBCT) to asses horizontal bone gain Results: The post operative recovery and healing phase was uneventful in all patients except in one patient in group II, where infection was observed 3 days post operatively. The horizontal bone gain was significantly higher in the control group (1.82± 0.62) than the intervention group (1.12 ± 0.59), consequently there was a significant statistical difference (P= 0.01). Conclusion: The vascularized inter-positional periosteal connective tissue flap has promising results in soft tissue and bone augmentation in the aesthetic zone as it offers a solution for type II sockets with thin soft tissue biotype in a single step. | ||
