Discuss the difference between guided tissue regeneration and guided bone regeneration

What will be an ideal response?

Guided bone regeneration (GBR) is a surgical procedure performed to increase the amount of alveolar bone available for the proper placement of a dental implant. The terms guided tissue regeneration and guided bone regeneration are often used interchangeably in literature but are really two different terms; however, they are based on the same basic principles. Guided bone regeneration describes the formation of only bone, not any other tissue, whereas guided tissue regeneration involves the formation of bone, cementum, and periodontal ligament around teeth. Guided bone regeneration surgery is indicated when there is a volume, height, or width deficiency of the residual ridge that prohibits implantation or optimal implant installation for esthetic and functional needs. Bone grafting and use of an absorbable (or nonabsorbable) membrane, which is placed over the bone defect site, is used to stimulate the patient's osteoblasts (bone-producing cells) to develop additional alveolar bone mass. This procedure is done about 6 months prior to placement of dental implants; however, it can be done in conjunction with dental implant placement surgery.
