BONE GRAFTING

Major and Minor Bone Grafting

Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.

We now have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and esthetic appearance.

THE BONE GRAFT PROCEDURES ARE REFERRED TO AS:

Sinus Lift Procedure

This procedure involves elevating the sinus membrane and placing the bone graft onto the sinus floor, allowing implants to be placed in the back part of the upper jaw. Often times, this can be performed at the same time as implant placement.

Ridge-Augmentation

In severe cases the ridge has been reabsorbed and a bone graft is placed to increase the ridge width and/or height. Bone is either taken from another part of the jaw to graft the deficient site, or bone granules are used from banked bone.

Distraction Osteogenesis

Using a tiny mechanical device, the height of the bony ridge can be lengthened to allow for placement of an implant of sufficient length to support a missing tooth.

These 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 third molar region or in the upper jaw behind the last tooth. In more extensive situations, a greater quantity of bone can be attained from the hip.

These surgeries are performed in the out-patient surgical suite under IV sedation or general anesthesia. After discharge, bed rest is recommended for one day and limited physical activity for one week.
