GUIDED TISSUE REGENERATION
 
  • Dental Codes:
    • D4266 - D4267 – Membrane (Guided Tissue) - Guided tissue regeneration – resorbable barrier, per site
  • Guided Tissue Regeneration (GTR) refers to procedures that attempt to regenerate lost periodontal structures (bone, periodontal ligament, and connective tissue attachment) that support our teeth. This is accomplished using biocompatible membranes, often in combination with bone grafts and/or tissue-stimulating proteins
 
  • How GTR Works:
    • GTR is a method for fixing periodontal issues to give a tooth or set of teeth additional stability and support. Periodontal disease, also known as periodontitis, is a condition in which bacteria under the gums become trapped, causing a chronic infection that eventually destroys the hard and soft tissues holding the teeth in place. The damage can occasionally cause gaps to develop between the teeth and bone.
    • A further, specialized treatment called a bone graft is frequently necessary to fill in these gaps or skeletal deformities. To encourage the formation of new bone, specific material is injected into the defect at this point. GTR uses artificial membranes that are either resorbable or non-resorbable to prevent soft tissue from forming in these damaged areas.
    • This membrane is important because it prevents the slower migrating bone-producing cells from populating and developing at the spot while allowing the quicker migratory soft tissue cells to do so.
 
  • How is GTR done?
    1. Surgery on gum and bone - Gum is taken out. employing a technique called a flap. All bacterial encrustations are removed out of the area under the gums. The injured bone is then covered with a membrane, either with or without bone transplant material.
    2. Separating tissues - The membrane, once positioned between bone and gum, gives the bone the time and space it needs to recover and begin to regenerate itself.
    3. After healing - The membrane and stitches either fall off or are taken out. To support the tooth or teeth, bone and new attachments will grow in about six months.
