guided tissue regeneration

regeneration of tissue directed by the physical presence and/or chemical activities of a biomaterial; often involves placement of barriers to exclude one or more cell types during healing or regeneration of tissue.

guided tissue regeneration

Abbreviation: GTR
Any of the techniques used in periodontics to reconstruct lost or diseased periodontal tissue in those with gingival recession. GTR often involves the use of absorbable barrier membranes or collagen.
