Guided Bone Regeneration is a predictable method to enhance the volume of the bone in deficient recipient sites prior to the implant placement. Crestal bone resorption is an inevitable consequence of extraction. Guided Bone Regeneration (GBR) can be done to regenerate adequate bone for successful implant placement. GBR can be performed by two different approaches: Simultaneous approach in which GBR performed simultaneously with implant placement and Staged approach in which GBR is done prior to the implant placement. Adequate blood supply plays a critical role in the regeneration
