GBR (Guided Bone Regeneration)
Guided Bone Regeneration GBR is a specialized dental service provided by the board-certified specialists at Aloha Dental Specialty Center in Beaverton, OR. Using barrier membranes and graft materials to rebuild bone exactly where implants need it.
Directing Bone to Grow Precisely Where It Is Missing
Guided bone regeneration (GBR) is a surgical technique that uses barrier membranes to exclude fast-growing soft tissue from a bone defect, creating a protected space where slower-growing bone cells can regenerate undisturbed. Without a membrane, fibroblasts from the gum tissue colonize the defect within days — far faster than osteoblasts — filling the space with scar tissue instead of bone. GBR prevents this competitive exclusion, allowing bone to form where you need it for implant placement.
At Aloha Dental Specialty Center, GBR is one of our most frequently performed augmentation techniques. Dr. Ostovar uses GBR for horizontal ridge defects, fenestration and dehiscence defects around implants, peri-implant bone defects, and localized vertical augmentation. The procedure involves raising a flap, decorticating the deficient bone surface, placing particulate graft material (allograft, xenograft, or a mixture) mixed with PRF, covering the graft with a barrier membrane (resorbable collagen or titanium-reinforced, depending on the defect), and achieving tension-free flap closure. The membrane is the essential element — it creates the biological boundary between soft tissue and bone-forming space.
GBR can be performed simultaneously with implant placement (when the implant is stable in existing bone but the surrounding bone is thin) or as a staged procedure (when insufficient bone exists to place the implant at all). Simultaneous GBR is common for buccal dehiscence defects — where the outer bone wall is thin or absent around an implant. The graft and membrane are placed around the exposed implant threads, and everything heals together over 6-9 months. For staged GBR, the grafted site heals for 5-9 months before implant placement. CBCT confirms bone maturation before proceeding.

Recovery & Healing Timeline
Understanding the healing process helps you plan ahead and follow post-operative instructions for the best possible outcome.
First 48 Hours
Mild swelling and tenderness are normal. Apply ice packs in 20-minute intervals and take prescribed or over-the-counter anti-inflammatory medication. Eat soft foods and avoid the surgical site when chewing.
Days 3 to 7
Swelling peaks around day three and then improves. The tissue begins closing over the surgical site. Continue with soft foods and use any prescribed antimicrobial rinse. Most patients return to normal activities during this phase.
Long-Term Healing
Surface tissue heals within two to three weeks. Bone integration and deep healing continue for three to six months. Avoid smoking, follow up as scheduled, and maintain good oral hygiene throughout recovery.

The Principle of Competitive Tissue Exclusion
GBR is built on a biological principle documented in the 1950s: when a bone defect is covered with a physical barrier, bone regenerates to fill the protected space. The barrier exploits a simple timing difference — gingival fibroblasts proliferate and migrate at rates far exceeding osteoblasts. Without a membrane, fibroblasts reach the defect first and fill it with connective tissue, leaving no room for bone formation. The membrane physically excludes these faster cells, creating a sequestered space that blood fills from the native bone surface. The blood clot organizes, mesenchymal cells differentiate into osteoblasts, and new bone forms along the graft scaffold. The membrane must maintain this protective function for 4-6 months — the time required for significant bone regeneration. Resorbable collagen membranes achieve this by resorbing slowly enough to maintain barrier function during the critical healing window.
Why Choose a Specialist?
GBR outcomes are surgeon-dependent to a remarkable degree. The same materials, placed by different surgeons, produce dramatically different bone volumes. The variables are technical: Is the membrane adapted intimately to the bone surface at its margins, or are gaps allowing soft tissue ingrowth? Is the graft packed to the correct contour, or will it collapse under the weight of the flap? Is the flap closed without tension, or will a stitch pull through and expose the membrane? Dr. Ostovar's daily experience with GBR — combined with CBCT-guided planning and PRF enhancement — produces consistent, predictable bone regeneration across a wide range of defect types.

A Note from Your Dental Team
In my experience, the patients who get the best results from guided bone regeneration gbr are those who come in with realistic expectations and follow their post-treatment instructions carefully. I’d rather spend extra time explaining what to expect than have a patient be surprised later.
“Every patient I see has a different story, a different set of concerns, and a different definition of what ‘success’ looks like. That’s why I don’t believe in one-size-fits-all treatment plans. When you come in for a consultation, I’ll listen first, examine second, and recommend third.
I also won’t recommend a procedure you don’t need. If your tooth can be saved with a filling instead of a crown, I’ll tell you that. If watchful waiting is appropriate, I’ll explain why. My job isn’t to sell treatment — it’s to give you my honest clinical judgment so you can make an informed decision.
If you have questions about whether this treatment is right for you, or if you’ve been told you need this procedure by another dentist and want a second opinion, call us at (503) 822-0096. We’re happy to take the time to explain everything — no rush, no pressure.”
— Dr. Merat Ostovar & Dr. Jovan Gvozden | Aloha Dental Specialty Center, Beaverton, OR
I know many patients feel anxious about dental procedures — you’re not alone in that. What I hear most often after treatment is: “That was so much easier than I expected.” We’re here to make this as comfortable as possible for you.
Are You a Candidate for Guided Bone Regeneration GBR?
Most patients in good general health are candidates for guided bone regeneration gbr. However, certain factors may affect your eligibility or require modifications to the treatment plan:
- Medical conditions: Uncontrolled diabetes, autoimmune disorders, or blood-thinning medications may require coordination with your physician before treatment.
- Bone quality: For guided bone regeneration gbr involving the jawbone, adequate bone density is essential. A CBCT 3D scan during your consultation determines this precisely.
- Smoking: Tobacco use significantly impairs healing. We strongly recommend quitting 2-4 weeks before and after any surgical procedure.
- Age: There is generally no upper age limit. What matters is your overall health, not your age. We have successfully treated patients in their 80s and 90s.
The only way to know for certain is a consultation with our board-certified specialists. Call (503) 822-0096 to schedule your evaluation — we’ll tell you honestly whether this is the right treatment for your situation.
Typical Healing Timeline:
Days 1-3: Initial healing, mild swelling managed with ice and medication. Days 4-7: Swelling subsides, gradual return to normal diet. Weeks 2-4: Soft tissue heals completely. Months 2-6: Bone remodeling and full integration (for surgical procedures). Individual recovery varies — we provide detailed post-op instructions specific to your procedure.

Frequently Asked Questions
What is guided bone regeneration (GBR)?
GBR is a surgical technique that uses a barrier membrane and bone graft material to regenerate bone in areas of deficiency. The membrane prevents soft tissue from growing into the bone defect, creating a protected space where bone cells can form new bone over the graft scaffold.
When is GBR used?
GBR is used to augment narrow ridges for implant placement, to cover exposed implant threads (dehiscence and fenestration defects), to rebuild bone around failing implants, and to augment localized bone defects that are too small for major ridge augmentation but too large for the implant to be placed without additional support.
What types of membranes are used for GBR?
Two main types: resorbable collagen membranes (dissolve over 4-6 months, no second surgery needed for removal) and non-resorbable membranes (titanium-reinforced PTFE, provide rigid space maintenance, must be removed in a second minor procedure). Collagen membranes are used for most routine GBR; titanium-reinforced membranes are reserved for large defects requiring rigid support.
Can GBR be done at the same time as implant placement?
Yes. Simultaneous GBR is commonly performed when the implant is stable in existing bone but the outer bone is thin or missing (dehiscence). The graft and membrane are placed around the exposed implant, and everything heals together. This combines two procedures into one.
How long does GBR take to heal?
Soft tissue heals in 2-3 weeks. Bone regeneration takes 5-9 months depending on the defect size and membrane type. A CBCT scan confirms bone formation before implant placement or implant loading. Resorbable membranes do not need removal; non-resorbable membranes are removed in a brief second procedure.
Is GBR painful?
The procedure is performed under local anesthesia with IV sedation available. Post-operative discomfort depends on the extent of the GBR. Minor GBR around an implant produces mild swelling for 3-5 days. Larger GBR procedures with significant graft volume involve more swelling and may require prescription pain medication for a few days.
What is the success rate of GBR?
GBR has documented success rates of 90-95% for horizontal bone augmentation and implant site preparation. Success depends on membrane stability, tension-free closure, adequate blood supply to the graft, and patient compliance with post-operative instructions. Smoking significantly reduces success rates.
What happens if the membrane becomes exposed?
Membrane exposure is the most common complication of GBR. If the gum tissue opens over the membrane, bacteria colonize the surface and can compromise the underlying graft. Small exposures may be managed with chlorhexidine rinses and close monitoring. Large exposures may require membrane removal and salvage of whatever bone has formed.
What graft material is used with GBR?
Particulate allograft, xenograft, or a combination, mixed with PRF. The choice depends on the defect type and the surgeon's assessment of the biological needs. Some defects benefit from the osteoinductive properties of allograft; others need the slow resorption and space maintenance of xenograft.
What is the difference between GBR and ridge augmentation?
GBR is a technique — it uses a membrane to guide bone formation. Ridge augmentation is a goal — rebuilding a deficient ridge. GBR is one of the techniques used for ridge augmentation. Other techniques include block grafting and distraction osteogenesis. In practice, many ridge augmentations are performed using GBR principles.
How much does GBR cost?
GBR costs range from $800-3,000 depending on the defect size, materials used, and whether it is simultaneous with implant placement or staged. Minor GBR around a single implant is on the lower end; large GBR procedures with titanium-reinforced membranes are on the higher end.
What is decortication and why is it important for GBR?
Decortication creates small perforations in the cortical bone at the graft site, allowing blood and stem cells from the cancellous bone to access the graft. This is essential for GBR because the blood supply from the native bone drives the regeneration process. Without decortication, the graft relies solely on blood supply from the overlying flap.
Can GBR be repeated if the first attempt is not fully successful?
Yes. If the first GBR produces some but insufficient bone, a second GBR can be performed. The cause of the incomplete result is assessed first — membrane exposure, graft resorption, or inadequate blood supply — and the technique is adjusted for the second attempt.
What is a fenestration defect?
A fenestration is an opening in the buccal bone that exposes the implant surface. It occurs when the bone is thin and the implant threads protrude through the outer cortex. GBR covers the exposed threads with graft and membrane, allowing bone to regenerate over the implant surface.
How do I care for the GBR site during healing?
Do not chew on the site for 6-8 weeks. Do not wear a removable prosthesis over the site without modification. Gentle brushing away from the suture line. Salt water rinses starting 24 hours after surgery. No smoking. Take all prescribed medications. Report any sudden swelling, drainage, or membrane exposure immediately.
