What does “Guided bone regeneration” mean?
Guided bone regeneration (GBR) uses a barrier membrane or other measures to maintain space for bone growth and encourage regeneration of deficient bone. It may be used with bone graft material around implants or in alveolar ridge defects.
Original spelling: GBR
The principle of maintaining space and stability
A barrier membrane prevents other soft tissues from entering the bone defect first, and stabilizing the clot and graft site is important. Graft material can maintain space and provide a scaffold for bone formation. Placing a membrane and material does not guarantee that the desired amount of bone will form.
Simultaneous or staged implant placement
The location, shape, and extent of deficient bone, soft tissues, and the ability to stabilize an implant are assessed. Depending on conditions, implant placement may be simultaneous or planned after bone reconstruction. Infection control and stable wound coverage are also considered.
Distinguishing its purpose from GTR
GBR centers on bone reconstruction, while GTR also aims to regenerate supporting tissues such as the periodontal ligament and cementum around natural teeth. Even with similar barrier principles, sites and assessment criteria differ. Membrane exposure or wound opening after surgery may require reassessment of the plan.
Frequently Asked Questions
Is it the same as bone grafting?
Bone grafting supplements an area by transferring material, while GBR manages regeneration space using a barrier membrane or other measures. They may be combined but are not identical terms.
Can I chew immediately after regeneration treatment?
It depends on wound and graft stability and the implant plan. Do not assume bone healing is complete just because the gum feels healed; follow eating and prosthetic instructions.
