Guided Bone Regeneration
Guided bone regeneration surgery is a dental procedure that uses the barrier membranes in a patient’s mouth to help guide and direct the growth of new bone and tissue in areas with insufficient volumes. This procedure is mainly for prosthetic restoration in patients with dental implants although esthetic restoration is sometimes used as well.
Guided bone regeneration is applied in the oral cavity to support new hard tissue growth to allow stable placement of dental implants. A very reliable and successful procedure when using bone grafting with guided bone regeneration.
The use of barrier membranes to help direct bone regeneration is not a new practice and the theoretical practices date back to 1959. By excluding unwanted cells from lining healing sites, the growth of desired tissues is much easier. Positive clinical results of regeneration led to the focus on the potential for re-building alveolar bone defects using regeneration. The theory of regeneration was challenged in the use of dentistry for awhile, but is now seeing a resurgence in positive clinical trials as a safe and effective treatment.
With the use of dental implants becoming widespread and predictable for the restoration of missing teeth and other cases, it’s clear the regenerative technique is an important step which assists the process of bone regeneration. The clinical success of implant therapy was taken from the direct anchorage of the implant in the bone tissue without the interposition of fibrous tissue. Clinical trials have been positive in proving to promote bone growth.
Guided bone regeneration has been reported as a reliable and successful means for augmenting bone regrowth in the case of vertical and horizontal defects in particularly edentulous patients. The data pulled from these implants suggests that GBR should be considered a safe technique to obtain bone formation and placing dental implants, especially in cases in which it would be otherwise impossible.
As patients with dental implants increase, so has the demand of treatment protocols that take less time and require fewer surgeries. With GBR, the patient undergoes a surgical procedure once, placed with initial stability, so the tissues regrow back without any pockets or problems that will cause the implants to uproot from there. It is clear that the use of a regenerative technique with dental implant placement is an important step which assists the process of a bone regeneration. Isolating the bone defect from the surrounding connective tissues provides bone-forming cells with access to a secluded space intended for the regeneration to take place.
The evolution of surgical techniques, awareness of tissue without the interposition of fibrous tissue, and the considerable research conducted to promote bone growth have all led to positive, safe, results.
Based on the research, GBR is not only a safe and effective technique for obtaining bone formation, but also makes dental implants available in situations where it would not otherwise be possible.
