In the past, the treatment of periodontal disease was considered to be painful and disfiguring. For many years, the best way to achieve the ultimate goal of therapy, resulting in shallow, maintainable pockets, was to do resective surgical procedures that often resulted in the exposure of sensitive root surfaces and the appearance of long teeth. Today, periodontists are often able to restore or regenerate missing bone and connective tissue attachment around teeth that are subjected to long-standing periodontal disease. In addition, if you have tooth loss due to trauma or disease, they can restore or regenerate bone prior to the placement of dental bridges or dental implants.
Learn more about these procedures below:
Guided Tissue Regeneration (GTR)
Refers to procedures that attempt to regenerate lost periodontal structures, such as bone, periodontal ligament and the connective tissue attachment that support our teeth. This is accomplished using biocompatible membranes, often in combination with bone grafts or tissue stimulating proteins.
Guided Bone Regeneration (GBR)
Refers to procedures that attempt to regenerate bone prior to the placement of bridges or, more commonly, implants. This is accomplished using bone grafts and biocompatible membranes that keep out tissue and allow the bone to grow.
Useful GTR and GBR Links
BioMend®: A resorbable collagen membrane that dissolves in eight weeks. No second oral surgery is needed to remove it. It is primarily used in GTR procedures. Treatment, Healing Steps: Also from Bio-Mend, this is a diagrammatic representation of the surgical steps and subsequent healing. Gore-Tex® Regenerative Material: Non-resorbable membranes used primarily for GBR procedures in preparation for or around dental implants.
Remember, not every case is suitable for grafting so ask your dentist. Continue below to see some examples of GTR and GBR cases:
GTR Case 1
Guided tissue regeneration (GTR) using a membrane and bone graft. Initial probing pocket depth: More than 11mm Final probing pocket depth: 4 mm at 10 months post-op
Surgery by: Dr. Ricardo Diaz
GTR Case 2
Guided tissue regeneration (GTR) using a membrane and bone graft. Beginning probing pocket depth: More than 12mm Final pocket probing depth: 4 mm at 12 months post-op.
Surgery by: Dr. Eduardo Lorenzana
GBR Case 1
Guided bone regeneration, using a biocompatible membrane and an autogenous bone graft of bone from the patient, mixed with deproteinized bovine bone mineral, from Bio-Oss®. Figure One: A careful flap reflection reveals a narrow ridge (3 to 4 mm wide), preventing implant placement at this time.
Figure Two: Seven months after the augmentation procedure, there is approximately 8 mm of ridge width available for implant placement.
Figure Three: A wide-diameter (5 mm wide by 10 mm long) implant was placed.
