In the past, the treatment of periodontal (gum) disease was considered to be painful and unsatisfied. The best therapy was to do resective surgical procedures that often resulted in the exposure of sensitive root surfaces and the appearance of "long" teeth.
Today, we are often able to restore or regenerate missing bone and attachment around teeth suffering from long-standing periodontal disease. In addition, if you have lost a tooth due to trauma or disease, we can restore or regenerate bone prior to the placement of bridges or implants.
Basically, these procedures attempt to regenerate lost periodontal structures, lost bone, periodontal ligaments, and connective tissue attachment that supports your teeth; using biocompatible membranes, bone grafts and/or tissue stimulating proteins. Missing bone and tissue can be restored to create a solid foundation for your beautiful smile.
Bone grafts are done to replace the lost bone. This lost portion of bone is called a “bony defect”. As destruction caused by periodontal disease, defects after tooth extraction, generalized decrease in the quantity of jawbone if the teeth has been extracted a long back or in the young age, defects around dental implants, defects resulting from cysts or tumor surgery.
Barrier membranes- In conjunction with bone grafting, membranes are often used to help stabilize the bone graft as well as to displace the gum tissue from invading the healing bone graft before it matures. Use of barrier membrane is known as Guided tissue regeneration or GTR. Membranes place around teeth are typically designed to dissolve away, or reabsorb, after several weeks of healing have passed.
How does it works?
When do one need a bone graft and/or GTR?
- The bone loss / destruction caused by periodontal disease around the teeth,
- Bone loss following trauma,
- Bone defect in region of extraction done a long back,
- To augment bone in implant site
- During sinus lift process before implant placement,
- To enhance the fit and comfort of removable prostheses,
- To enhance esthetics of a missing tooth site in the smile zone,
- Following extraction, in case implant is planned.
What are the types of bone graft?
- Autogenous- means self. Bone harvested from one area of the patient and transplanted to another area.
- Allograft- either synthetic bone or bone from a bone bank.
- Xenograft- bovine bone.
