Guided Bone Regeneration
Guided bone regeneration (GBR) is a grafting technique that rebuilds bone at an implant site. Graft material is placed in the deficient area and covered with a barrier membrane; the membrane keeps faster-growing gum tissue out of the space so that slower-forming bone can regenerate in its place.
GBR is used for localized bone defects — for example a thin spot of bone over an implant, or a small ridge deficiency. It can often be performed at the same time the implant is placed, or beforehand when a larger volume of bone needs to be rebuilt first.
Who it's for
- Localized bone defects at or around a planned implant
- Thin bone over part of an implant that needs reinforcing
- A small ridge deficiency that can be corrected during implant surgery
- Patients who want to preserve a predictable foundation for implants
What to expect
- 1
Assessment & 3D imaging
CBCT imaging defines the size and shape of the bone defect and the right approach.
- 2
Graft & membrane
Graft material is placed in the defect and covered with a barrier membrane to direct healing.
- 3
Protected healing
New bone forms beneath the membrane over the following months while soft tissue is kept out of the space.
- 4
Implant placement
When the bone has matured — or at the same visit in suitable cases — the implant is placed into the restored bone.
Recovery & aftercare
Mild swelling and soreness for a few days are typical and managed with over-the-counter pain relief. You'll receive specific instructions to protect the membrane and graft while they heal.
When GBR is done ahead of placement, the bone matures over several months; the timing is confirmed at follow-up.
Common questions
- How is guided bone regeneration different from a bone graft?
- GBR is a specific grafting technique: it adds a barrier membrane over the graft so that gum tissue can't grow into the space and crowd out the regenerating bone. It's often used for localized defects at implant sites.
- Can it be done at the same time as the implant?
- Often, yes. Smaller defects are frequently treated with GBR during implant placement; larger ones may be rebuilt first and the implant placed once the bone has matured.
Want a second opinion first?
If you've been quoted implant, bone-grafting, or sinus-lift treatment and want to be sure it's the right plan, a specialist second opinion is a low-cost, no-pressure way to confirm your options before you commit.
