When a patient's bone does not have the necessary height or thickness, implantologists use a bone graft, which is, in fact, a bone mass transplant. The application of the bone graft is performed by a minor surgery on the gums. Most of the time, its application is done at the same time as the installation of a dental implant Chicago area surgeons perform.
There are several types of bone grafts: autograft (the tissue is collected from the patient`s body), allograft (the tissue comes from another patient), xenograft (bone tissue of animal origin), or alloplastic (artificial bone tissue).
In many cases, the bone graft is in the form of granules and acts temporarily, and over time the process of osseointegration takes place (process by which bone tissue is formed around the dental implant, resulting in increased stability and integration).
Usually, the bone graft will be completely absorbed and integrated in the place where it was placed. The duration of absorption may vary from patient to patient (3-6 months).
Why does the bone retract? Most of the time, when someone starts suffering from this condition, it is about an untreated periodontal disease. Loss of natural teeth or excessive pressure exerted by the upper teeth on the lower ones during chewing can be causes of bone retraction.
