GTR (Guided Tissue Regeneration)

GTR (Guided Tissue Regeneration) is a periodontal surgical procedure designed to encourage the regeneration of lost bone and supporting soft tissue around teeth or dental implants. The technique places a biocompatible barrier membrane between the gum tissue and the defect so that slower-growing bone and ligament cells can repopulate the area without being outcompeted by fast‑growing gum tissue; this can help restore the structural support around a tooth or implant and improve long‑term stability.

The procedure commonly involves cleaning the defect, placing a membrane (resorbable or non‑resorbable) and sometimes adding bone graft material to fill gaps and support new growth. Healing time and outcomes depend on the size of the defect, the patient’s oral hygiene and overall health, and whether the membrane is left in place or removed later; risks can include infection, membrane exposure, or partial regeneration, so follow‑up care and maintenance are important for success.
