Guided bone regeneration is a dental procedure that is used for increasing bone mass in cases where vertical and/or horizontal defects in the jawbone exist. It is a reliable method for re-establishing hard tissue volume in areas of bone loss, which has taken place in the upper or lower jaw as the result of periodontal disease, trauma, cyst or tumor surgery, or subsequent to a dental extraction.
During a guided bone regeneration procedure a special membrane is positioned to cover a newly placed bone graft in the area of a bony defect. This membrane facilitates new growth of bone, while preventing any growth of unwanted soft tissue into the area.
Guided bone regeneration can enable the placement of dental implants for cases in which implants would otherwise not be possible
Guided Bone Regeneration (GBR) is a surgical dental procedure that increases bone mass in the jaw where defects exist. A bone graft is placed and covered with a special barrier membrane to direct new bone growth while preventing soft tissue from interfering.
If you lack sufficient jawbone volume for a stable dental implant, GBR builds up bone so implants can be placed securely. It’s commonly recommended when bone loss is due to periodontal disease, trauma, cysts, or prior tooth loss.
During the procedure, the surgeon places bone graft material in the defect area and covers it with a membrane. This membrane supports new bone growth while healing.
Healing time varies, but bone regeneration typically takes several months (often 6–9 months) before enough bone is formed for implant placement or full restoration.
Most patients feel minimal pain during the procedure due to local anesthesia. Some discomfort, swelling, and mild bruising are normal afterward, and are managed with medication and aftercare instructions.
Following GBR, patients are usually advised to follow a soft diet, avoid hard or chewy foods, and refrain from using straws to prevent pressure on the surgical site.
Risks can include infection, membrane exposure, delayed healing, or graft failure. Following post‑operative care instructions closely reduces complications.
While GBR has a high success rate, failure can occur if there’s significant bone loss, infection, poor healing, or disruption of the membrane. Your periodontist will evaluate your case to optimize success.
A standard bone graft adds bone material, but GBR includes a barrier membrane that guides bone cells into the defect while excluding soft tissue — improving outcomes in implant sites.
Coverage varies by plan. Some insurance policies cover all or part of GBR when medically necessary, but many require pre‑authorization. Check your policy and contact Adam L. Bear, DDS, PLLC for assistance with claims.
