Biomaterials for Guided Bone Regeneration: Science and Rationale

Dental implant placement requires adequate bone volume. There are multiple techniques employed to augment the lost volume, using a plethora of biomaterials available. Many authors have written on the properties of a biomaterial when used in a specific indication and its behavior over time. This review puts together the basics of bone biomaterials along with a critical analysis with respect to their biologic potential, turnover and stability. It also presents a plausible recommendation of which biomaterial to use in a particular clinical presentation with a classification of biomaterials according to type, form and processing.
