Bone Grafting | Shoreline & Seattle WA
In nature, form follows function. Over time, the bone associated with missing teeth shrinks away. This process is called resorption or “disuse atrophy.” Sometimes, resorption takes away the bone needed to anchor a properly sized dental implant. When necessary, missing bone can be reconstructed to provide a foundation for a dental implant. Grafting provides the quality and quantity of bone necessary for the placement of properly sized dental implants. Grafting can also help restore the esthetic appearance of the lips and cheeks. Bone for grafting procedures can be easily obtained from other areas of the jaw. In many instances, pre-packaged bone graft mineral can be used. Some of the grafting techniques performed at North Sound Oral Surgery include:
When a tooth is removed, the bone at the extraction site tends to collapse inward and shrink over time. However, bone can be maintained and even improved in terms of its volume and density by the addition of bone mineral to the extraction site. The bone mineral is pre-packaged as granules similar to coarse sand. It is gently packed into extraction socket and covered with a dissolving collagen sponge. Over three to four months, surrounding natural bone replaces this matrix, resulting in the formation of dense, high quality bone for future implant placement.
The maxillary sinuses are behind your cheeks and above of your upper back teeth. The cheek sinuses are like empty rooms, and not much goes on inside of them. Sometimes after an upper back tooth is removed and the socket heals, only a thin layer of bone will remain under the sinus. When the sinus floor is thin, grafting to the area may be necessary before implants can be placed. Sinus lift grafting is a simple procedure and has an excellent success rate. Sinus grafting and implant placement can often be performed as a single procedure. However, if the bone level is very thin, the sinus graft will have to be completed and allowed to heal for several months before implants can be placed.
In some cases, when teeth have been missing for extended periods of time, the bone remaining in the area may become too narrow and/or too short for implant placement. In these instances, small, carefully prepared and fitted grafts can be placed at the implant sites to provide adequate bone thickness and/or height.
These grafting procedures may be performed separately or at the same time your implants are placed, depending upon the individual’s condition. In many instances, a bone substitute can be used which will turn into solid living bone as your body heals. In other instances, small sections of bone taken from the area of the chin or the back part of the jaw will be the best solution. In rare and extensive situations, a greater quantity of bone can be attained from the hip or the outer aspect of the shin bone below the knee. When extensive grafting is necessary, using the patient’s own bone usually gives the best results. North Sound Oral Surgery also utilizes advanced regenerative techniques to accelerate and promote bone formation in deficient areas. One method utilizes concentrated growth factors obtained from your own blood. Another technique uses a laboratory synthesized growth factor produced with the latest biogenetic techniques.
These surgeries are performed in our office surgical suite, usually using IV anesthesia to maximize your comfort.
