Bone Grafting (Onlay Bone Grafting)

When teeth are not present in the mouth, the supporting jawbone around the teeth slowly dissolves away due to lack of exercise. This also occurs with some gum problems. The result is insufficient bone to support dental implants. Bone may be grown allowing implants to be placed later. Specially treated bone from a bone bank may be placed in the area where bone is deficient.

The added bone is left to integrate with the natural jawbone before implants are placed. Depending on the amount of bone being grown implants may be placed after four to nine months. Occasionally it may be necessary to wait a little longer.

Implants are left to become firmly attached to bone for a number of months before a denture or crown and bridgework is fitted to them.
