Bone grafting is used to recreate bone and soft supporting tissues lost due to gum disease. It’s also called regenerative surgery. The goal of this surgery is to coax the body into rebuilding the bone and other structures that attach a tooth to the jaw.
First, Dr. Lareau will separate the gums from your teeth to gain access to the roots and bone. The roots will be thoroughly cleaned. The holes (defects) in the bone will be filled in with a graft material (usually your own bone, cadaver bone, cow bone, or synthetic material) and covered with a physical barrier.
Barriers are used to cover the grafting material in the early stages of healing. They also prevent the gums from growing into the bony defect. Barriers are made from human skin, cow skin, or synthetic materials. After the graft is in place, the gums will be put back over the treated site and stitched into place. The site also may be covered with a bandage known as a periodontal pack or dressing. During the next six to nine months, your body fills in the area with new bone and soft tissue and reattaches the tooth to your jaw.
Sinus grafting, often referred to as sinus lifting or sinus augmentation, is an oral surgery procedure in which bone is added to the upper jaw, in the area of premolar and molar teeth. The goal of this surgery is to graft enough bone material onto the upper jaw to support the base of a dental implant. This procedure can require up to six months of healing before placing the dental implants.
Gingival grafting, often referred to as gum grafting or periodontal plastic surgery, is a generic name for any of a number of surgical periodontal procedures whose combined aim is to cover an area of exposed tooth root surface with grafted oral tissue. Dr. Lareau uses this procedure for periodontally compromised patients who need to prevent further root exposure, decrease or eliminate sensitivity, decrease susceptibility to root decay, and to improve aesthetics.
Connective Tissue Grafting
Connective tissue grafting, often referred to as a CT graft, is used to obtain root coverage for patients who have periodontal recession (receding gums). First, Dr. Lareau will make a small pouch in your gums, borrow some tissue from the roof of your mouth, place the tissue into the pouch, and close the flap back up. In essence, we are using you as your own Band-Aid. The roof of your mouth will also be sutured and the tissue will regenerate. This tissue will integrate with your gums. Usually we can cover up most, and sometimes all, of the recession that has taken place. This surgery will prevent further root exposure, decrease or eliminate sensitivity, decrease susceptibility to root decay, and improve aesthetics.
Onlay grafting may be necessary to recreate bone for a dental implant in areas where teeth have been missing for a long time, or where an infected tooth has caused destruction of the bone in the area. Most often, we will use your own bone (usually from the wisdom tooth or chin areas) and closely fit the graft to lie over the area of bone deficiency. Onlay bone grafts are then fixed to the underlying bone with special bone screws, which are removed when your dental implant is placed. Normally, several months are allowed for the bone graft to heal and fuse with the underlying jaw bone. When this healing is complete, Dr. Lareau will place the dental implant and follow your healing until your restoration is ready to be made by your family dentist.
