Bone loss is not unusual for people who have periodontal disease, missing teeth or as a result of a traumatic injury. Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed creating a bone defect. This often leaves a condition in which there is poor quality and or quantity of bone suitable for placement of dental implants.
Dr. Delgado & Dr. Kuzmik now have the ability to grow bone where needed by placing a bone graft to the area. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore function and esthetic appearance. The bone graft procedures are referred to as:
Sinus lift procedure
When upper back teeth are lost the bone quantity diminishes and the sinus cavity enlarges. If there is not enough bone in the upper jaw, we can add bone to this area. This procedure involves locating and elevating the sinus lining to preserve sinus integrity and placing the bone graft below the sinus. This will restore the bone height and width to ensure that dental implants of adequate length can be placed.
In severe cases the jaw bone has been reabsorbed, a bone graft is placed to increase height and/or width.
The inferior aveolar nerve, which gives feeling to the lower lip and chin, may need to be moved in order to make room for placement of dental implants to the lower jaw.
These three procedures may be performed separately or together, depending upon the individual’s condition. There are several areas of the body which are suitable for attaining bone grafts. In the maxillofacial region, bone grafts can be taken from inside the mouth, in the area of the chin or in the wisdom tooth region in both the upper and or lower jaws. In more extensive situations, a greater quantity of bone can be attained from the patients own hip or shin bone. For some procedures laboratory sources (animal/cadaver) and/or synthetic materials are used.
These surgeries are performed in the office surgical suite under intravenous anesthesia or local anesthesia. If the surgery is required in a hospital setting, then bed rest is recommended for one day and physical activity is limited for one week following your discharge.
