Guided tissue regeneration (GTR)

Guided tissue regeneration (GTR) is a type of therapy used to regenerate damaged periodontal tissue.
In cases in which the alveolar bone and periodontal ligament supporting the tooth have been damaged due to gum disease, etc., if left untreated, the periodontal tissue becomes thinner instead of regenerating. GTR is a method of regenerating damaged periodontal tissue to a condition as close to the original as possible.
Cleaning between the tooth and gum is performed to place an artificial special membrane between the residual periodontal ligament and gum or other tissue without mixing the both. This facilitates regeneration of the target periodontal ligament, and the periodontal tissue then becomes capable of supporting the tooth within several months.
Regeneration of periodontal tissue with this method may allow the placement of implants even in patients who cannot undergo implant treatment due to poor periodontal tissue incapable for supporting implants.

Procedures

1.The gum is lifted away from the tooth root to remove any attached plaque and clean thoroughly or resect the affected region.

2.The region of breakdown of the alveolar bone and periodontal ligament is covered by an artificial membrane, over which the gum is replaced.
* The reason for covering with an artificial membrane is to separate the region to be regenerated from other tissue.

3.If the space necessary for regeneration of the alveolar bone and periodontal ligament is secured, they will be regenerated without several months.

4.Absorbable and non-absorbable type artificial membranes are available. Those of the absorbable type are absorbed into the body over time, while non-absorbable membranes require surgery for removal.
