For dental implants to be successful, the patient’s jawbone must have enough bone across the ridge to be able support a dental implant. When a patient experiences tooth loss it often leads to more loss of bone over time. This tooth loss can be caused by:
Bone grafts success rate for placing dental implants in the jaws is very high. There is always the possibility that the bone graft will fail, even if the surgeon has used your own bone. The process of bone grafts is very different than organ transplants and many Dentists don't know why some bone grafts fail. It is a known medical fact that certain patients, being those that smoke, or have a compromised immune system experience higher failure rates than other patients.
Just as with one missing tooth, several missing teeth can be easily treated with dental implants. Implant supported teeth are permanently fixed in the mouth, unlike removable appliances like dentures. They don’t slip or click, and there is no worry about them moving or falling out when speaking, eating, or participating in activities. And because dental implants are placed directly into the bone, they help preserve the jawbone and prevent bone deterioration. If the implants will be placed next to natural teeth, the natural teeth and surrounding gums must be in good health. If you don't have enough bone to place and support the dental implants, the supporting bone can be built up using bone augmentation or grafting before the actual implant procedure begins.
