What is guided tissue regeneration (gums)?

Surgical aid. Gtr is a procedure used to stimulate bone and gum tissue growth when done in combination with flap surgery. A small piece of mesh-like fabric is inserted between the bone and gum tissue. This keeps the gum tissue from growing into the area where the bone should be, allowing the bone and connective tissue to regrow and restore lost bone.
GTR. When tooth required bone grafting, gtr is a process of using a membrane barrier to contain the graft and prevent the epithelial migration into the graft to allow for selectively guide the growth of bone and tooth attachment (bone, cementum, periodontal ligament). Gtr is done to enhance regeneration of bone, cementum, and pdl instead of repair (connective tissue and long junctional epithelium).
