Guided Tissue Regeneration – What does it mean?
Written by: Dr. Clifford Melnick, DMD
Periodontal Bone Loss- What causes it?
In areas of the mouth where the bone loss is more vertical in nature (imagine a “V”) whereby bone granules can be contained, we routinely pack the area with bone grafting…in our office we utilize bovine (cow) bone. It is extremely safe and has been successfully used on thousands of patients.
In a surgical site, there is always a race between the gum cells and the bone cells to fill a void. The gum cells always win the race because they migrate much faster than the bone cells ( 1mm/day). Guided tissue regeneration is a way to exclude the gum cells thereby allowing the bone cells to have a chance to migrate into the site and take root…no pun intended! So, what we do during surgery is pack the bone graft into the bone defect after thoroughly cleaning it out and then we drape the site with a specialized collagen membrane which prevents the downgrowth of the gum cells (epithelium). Then we suture the gum closed and the body does the rest. The collagen GTR membrane bio-resorbs or disintegrates in approximately 6 weeks after the procedure so there is no need to go back in to remove it as was needed in first generation membranes years ago.
Approximately 6 months after guided tissue regeneration is performed, x-ray evidence of new bone is often seen on radiographs and the gum pockets shrink dramatically to levels that are maintainable by the patient.
At Fifth Avenue Periodontics located in midtown manhattan, we routinely perform the GTR procedure for our patients. Please call us for an appointment at (212) 355-1266.
