Guided Bone and Tissue Regeneration

Gum disease has traditionally been treated by eliminating the gum pockets by trimming away the infected gum tissue and by re-contouring the uneven bone. Although this is still an effective way of treating gum disease, new and more sophisticated procedures are routinely used today. One of these advancements is guided tissue regeneration. This procedure is used to stabilize endangered teeth that have deep bone defects around them.


As periodontal disease progresses, pockets of degenerated bone develops in the jaw. These pockets can promote the growth of bacteria and the spread of infection. To address these pockets, Dr. Yamaoka may recommend guided tissue regeneration. During this surgical procedure, the bone defect created by the bacteria is cleaned thoroughly, a bone graft is placed to fill the defect, a regenerative protein is added to enhance healing and a resorbable membrane is installed between the soft tissue and the pocket in the bone to “guide” healing. The membrane covers the bone defect so that fast-growing soft tissue is blocked and slower-growing bone can begin to grow and regenerate itself.
