Your bone and gum tissue should fit snugly around your teeth like a turtleneck around your neck. When you have periodontal disease, this supporting tissue and bone is destroyed and pockets develop. Eventually, if too much bone is lost, the teeth will need to be extracted.
Dr. Chang may recommend a regenerative procedure when the bone supporting your teeth has been destroyed. These procedures can reverse some of the damage by regenerating lost bone and tissue.
During this procedure, your periodontist folds back the gum tissue and removes the disease-causing bacteria. Membranes (filters), bone grafts or tissue- stimulating proteins can be used to encourage your body's natural ability to regenerate bone and tissue.
There are many options to enhance support for your teeth and to restore your bone to a healthy level. Your periodontist will discuss your best options with you.
What are the benefits of this procedure?
Eliminating existing bacteria and regenerating bone and tissue helps to reduce pocket depth and repair damage caused by the progression of periodontal disease. With a combination of daily oral hygiene and professional maintenance care, you'll increase the chances of keeping your natural teeth – and decrease the chances of serious health problems associated with periodontal disease.
What does bone grafting treatment involve?
Bone grafting is a fairly simple procedure that can be performed under local anesthetic; however, if large amounts of bone area need to be grafted, general anesthetic may be required.
Initially, the grafting material needs to either be harvested or prepared for insertion. A small incision is made in the gum tissue and then gently separated from the bone. The bone grafting material is then placed at the affected site.
The bone regeneration process may be aided by:
Gum/bone tissue regeneration – A thin barrier (membrane) is placed below the gum line over the grafting material. This barrier creates enough space for healthy tissue to grow and separates the faster growing gum tissue from the slower growing fibers. This means that bone cells can migrate to the protected area and grow naturally.
Tissue stimulating proteins – Enamel matrix proteins occur during natural tooth development. Emdogain is a matrix protein product which is usually placed on the affected site before the gum is sutured. It mediates the formation of accellular cementum on the tooth which provides a foundation to allow periodontal attachment to occur. Tissue stimulating proteins help create lost support in areas affected by periodontal defects.
Platelet-rich growth factors – A high platelet concentration liquid can be used to create a blood clot at the site of a wound. It has recently been discovered that PRGF also stimulates bone growth – meaning a denser graft in a shorter time period.
The gum is sutured in place and a follow-up appointment will need to be made to assess progress. Bone grafting is a highly successful treatment and a good base for further periodontal restorations.
