GTR is a method used to repair periodontal defects so that a tooth, or set of teeth, has more support and stability. Periodontal disease (periodontitis) is a process where bacteria trapped under the gums leads to a chronic infection. This causes the hard and soft tissues that support the teeth to break down. In certain cases, this leads to gaps that form between the teeth and bone. These gaps, or bony defects, often need to be treated with a separate procedure known as a bone graft. This is where material is placed into the defect to promote new bone growth.

GTR uses a resorbable or nonresorbable artificial membrane. These keep soft tissue from growing into the gaps. The membrane blocks the fast-growing soft tissue cells from growing into the site. This lets the slower-growing bone-making cells to grow there instead. This is how GTR is done:
