Clinical and Histological Evaluation of Healos® for Alveolar Ridge Augmentation
Study Details
Study Description
Brief Summary
The purpose of this study is to document and evaluate how a bone graft material (Healos®) can help rebuild bone width. Dental implants can only be placed when enough bone is found and this bone graft may help to rebuild bone width for dental implant placement. The ultimate goal of this study is to evaluate how this graft material can help bone healing.

Procedure: Alveolar ridge augmentation
Under local anesthesia, full-thickness mucoperiosteal flaps will be elevated, followed by degranulation, and collection of all clinical measurements. Crestal and vertical releasing cuts will be performed using diamond-coated discs on the edentulous ridge in need of augmentation. A sequence of bone chisels and osteotomes will be used to split the alveolar ridge in half until a desirable width for implant placement is achieved. Healos® will then be inserted between both osseous plates. Fixation screws will be used as needed to stabilize the expanded alveolar ridge. Collagen barrier membranes (Ossix Plus) will be used to cover the osseous wound. Flaps will be approximated to achieve primary wound closure.
