Horizontal bone augmentation using a mixture of cortico-cancellous allograft and bovine bone mineral with a collagen membrane: a retrospective study

Aim: The study aimed to evaluate the clinical outcomes of bone augmentation with a mixture cortico-cancellous allograft and xenograft collagen membrane in horizontal knife-edge alveolar crests.
 Material Method: Patients ridge thickness less than 4 mm by preoperative tomography were included study. Twelve patients (10 Female, 2 Male) treated Cortico-Cancellous Allograft Bovine Bone Mineral membrane.
 Results: Thirty-nine implants placed twelve patients. initial is between 1 cm (mean: 3±0.89440). Nine months after augmentation, varies 4.53 9.15 4.62±1.16782). gained 1.27 7.72 (mean 3.66±1.21041).
 Conclusion: Augmentation bones crestal margins simple, successful, feasible.
