Improvement of alveolar bone height using novel graft placement

A rabbit mandible bone onlay model was used to compare the ability of implants with various bioactive surfaces to facilitate supracrestal bone augmentation without the use of any barrier membranes. Our specific aim was to determine whether dental implants with bioactive surfaces such as calcium phosphate coated or alkaline treated surfaces promoted more vertical bone formation than roughened titanium implant surfaces when used in conjunction with an osteoinductive synthetic graft material. This study demonstrated that substantially greater amount of new bone is present on calcium phosphate coated implant surfaces than on either of the alkaline treated or rough surfaced types.
