Advances in the field of periodontics have led to the development of materials and techniques to regenerate bone and tissue lost from disease. These procedures require an experienced surgeon and good oral hygiene by the patient. It can only be used in certain types of defects, and your periodontist will discuss with you if regeneration may be achievable.

The figure above shows a simple diagram of guided bone and tissue regeneration. In A, a bone defect is present. In B, materials such as bone graft and growth factors are placed in the defect. C – A membrane is used to cover the defect to prevent gum tissue from growing in, allowing slower-growing tissues like bone to mature in the space. D – With good oral hygiene and post-operative care, a blood clot forms and your body starts to regrow the lost tissue. E – After 3-6 months, new tissue and bone is formed and the defect is repaired.

In certain cases of deep pockets, usually 6mm and greater, your periodontist may recommend surgery to correct the pockets. Deep pockets are more difficult to clean and home and by the hygienist. Bone defects may be preventing adequate maintenance allowing the disease to progress. The goal of the procedure is to reshape the bone and lower the pocket to allow for a cleansable, maintainable environment to help the gums return to a healthy state.

The procedure is performed under local anesthesia, and you may request sedation for the procedure. It will last about an hour per quadrant, and you will be asked to return for 1 week and 3 week follow up visits. A 3 months, you will receive a maintenance cleaning, and assess your hygiene. At 6 months your periodontist will again assess your hygiene and healing, and re-measure the pockets. A successful treatment will return the pockets to healthy, normal depth, and allow for easier home care. Afterward, you will be recommended a maintenance program to prevent the disease from recurring.

What is LANAP®?

LANAP®, or the Laser Assisted New Attachment Procedure, is one of the newest and most advanced procedures for the treatment of periodontal disease. It is a FDA-approved treatment for chronic inflammatory gum disease. The laser works initially in the space between the gum and the tooth (periodontal pockets) to kill bacteria inside of the pocket, which was the source of the problem. The laser can see the difference between healthy and diseased tissue and selectively destroys diseased tissue, and can see where the bacteria is and specifically kills it as well. The laser seals the gum up against the tooth, creating a clean, disinfected, closed and stable environment for the body to kick in its own natural defenses and healing capacity.

The procedure is exceptionally selective and safe. There are no incisions or stitches involved in the procedure.

While in some cases of Periodontal disease, traditional gum surgery might still be the treatment modality of choice, LANAP® is generally a viable alternative for most patients. Dr. Liu will give you advice of treatment options after a thorough evaluation of your periodontal and dental condition.
