Guided Bone Regeneration


Guided bone regeneration or GBR has been used for over 40 years in implant dentistry. It is most often used when the bone is lost in width and/or when a minimal to moderate amount of bone has been lost. It is most often used when a tooth is extracted and a defect in the bone remains, leaving inadequate bone for implant placement.

The bone used in guided bone regeneration can be from 1) another part of the body (smaller pieces than with block bone regeneration), 2) bone from cadavers, 3) bone from animals, 4) bone from calcium sources (primarily coral or plaster of paris), 5) bone substitutes that are manufactured. Human and animal bone that has been processed and shaped into sand sized particles are used extensively in implant dentistry both for this and other applications. Human bone has been used for over 50 years as a bone graft in the mouth. Both human and animal bone products are treated by multiple sterilization methods to eliminate any bacteria, virus', and foreign proteins, which makes them a universal donor material. Countless research papers and clinical studies have shown them to be safe, even for people with multiple allergies and sensitivities. Multiple members of my team, my wife and my self all have had these materials used in our mouths to have dental implants placed.

These bone particles are often mixed with antibiotics and placed into the defect. Several different kinds of membranes can be used over the bone particles to help keep soft tissue from growing into the boney defect.

The bone then changes these bone particles into new bone, replacing them over the months that follow. With a medium to a large defect in the bone, the bone particles covered by the membrane are allowed to heal and integrate 5–9 months. An implant can often be placed at the same time as the guided bone regeneration procedure is performed in a small to medium sized defect as with Socket Bone Regeneration.

Once the implant is placed, the bone is allowed time to integrate with the implant before the final crownwork/bridgework is fabricated. If desired, temporary teeth can be made and fixed to the implants in many cases where guided bone regeneration is used.
