A guided tissue regeneration is a dental procedure which aims at covering the exposed root surface of the teeth and preventing further bone and tissue loss. The procedure is directed toward regaining lost supporting tissues surrounding the teeth. The loss of attachment may be brought about by gingival recession. A gingival recession is characterized by exposure of a portion of the root (cementum).

The gum tissues surrounding the teeth, if not properly cared for, may develop conditions like gingivitis. This is a condition wherein the gingiva (gums) become swollen and inflamed. Destruction of the bones and tissues supporting the teeth may result from improper brushing technique or poor dental hygiene bone and tissue over a period of time. Incorrect and insufficient oral care may lead to the development of plaques and tartar.

The bacterias that grow from the calcular deposits will then attack the surrounding gingiva as well as the bones and teeth structures. If the condition continues the gums will continue to swell from bacterial infection. This can result to gingival recession.

To prevent having gingival depths, it is essential that gingival and subgingival plaques be removed the earliest possible time. However, a patient who is experiencing pain from the swollen gums will immediately have them checked.

During consultation, as the dentist probes the depths of this gingival inflammation, a depth 10 mm or more is indicative of a significant loss of periodontal attachment. Usually, subgingival deposits are found. An x-ray image of the affected tooth will show darkened area on the site of bone loss. This will prolong the inflammation.



Procedure of Guided Tissue Regeneration

During the procedure calcular deposits are scaled off of the root surface. Agents such as ethylenediaminetetraacetate (EDTA)or citric acid are used to condition the root for the graft. Local antibiotics may be used as well. The defect will then be filled with powdered bone. A barrier membrane will then be used to cover the graft. The gingiva are repositioned over the bone graft and carefully protected with a surgical splint during the healing. After a few months of healing the defect area is reassessed. Normal tissue color in probing suggests that the graft has been successful. The patient will be instructed a close follow up and preventive maintenance is essential to ensure the best long-term prognosis for the grafted area.



Significance of the procedure

Guided tissue regeneration would significantly prevent massive bone and soft tissue loss. It aims at rebuilding and regaining the lost tissues by repairing them to return to its normal attachment with each other. As the teeth gains stability from the reconstruction, so is the overall health. Generally, it helps restore the normal function of the oral cavity and serves promote esthetic function to an individual.

Continuous oral health maintenance will ensure a good prognosis. Make sure to follow up with the periodontist to ensure success of the procedure. The progress must be carefully monitored to be assured of complete healing and recovery. This procedure is functionally and esthetically significant.
