Contemporary dental implant therapy has flourished in recent years thanks in large part to advances made in bone augmentation capabilities. Bone grafts, which are often crucial to the success of implant restorations, are used mainly in three instances: at the time of extraction for delayed implant placement, when an immediate-socket implant is placed, and for ridge augmentation either laterally or vertically. Many bone grafting options are available to the surgeon depending on the site to be treated and the requirements in the area. Bone grafts and barriers come from different sources and are seen by the body's cell types in different manners. This yields a variety of biological outcomes, some of which have been published while others are in the process of being studied.
