Bone grafting will be needed when patients have gone a long time without teeth and the bone has eroded significantly. This erosion happens over time as nature finding no use for the jawbone gradually starts resorption of the bone and gum causing them to shrink.
Advanced bone grafting allows the bone to be rebuilt. After the jawbone has been rebuilt through grafting implants can be placed.
Grafts are mainly of 4 types:
Autografts: Grafts for this technique are taken from person’s own body. It is harvested from either the hip or the mouth of the patient and grafted on to the site of the implant or where the bone depth and width is very low. As the bone taken is the patient’s own the compatibility is high and risk of rejection is low. Best results with the greatest bone regeneration occurs through this method.
Allografts: If for some reason you are suitable candidate for Autografts then Allografts are done. In this technique bone is harvested from other human donors and grafted into your mouth. For this a lots of tests are run to match for compatibility and also, the donor does not have any transmittable diseases. *
Xenografts: In this technique bone is harvested from animals. The animal bone goes through several processes to make it compatible for humans and grafted onto the implant site. Over time your body will replace this with natural bone.
Alloplastic grafts: These are man-made bone. Inert and synthetic materials are used to create artificial bone. This bone over time becomes the framework for natural bone to build over. Sometimes the artificial absorb-able bone is places which over time gets absorbed and body’s own natural bone replaces it.
These bone grafting techniques are gifts of modern science to man as its allows for them to regain many of the bodies lost functions. Using these grafting techniques dental implants are placed in patients of any age group and they enjoy a better quality of life as a result.
