Bone grafts will help to make your implant possible

A bone graft will increase the bone density of your jaw, creating a solid foundation in which to place a dental implant. This is a highly specialised dental procedure, which we can perform here in our clinic in Neutral Bay.

What is a dental bone graft?

A bone graft is performed when there is no longer enough bone in the jaw to support a dental implant. The treatment will vary according to the severity of bone loss that may have occurred as a result of a missing tooth or periodontal disease. If the loss is moderate, a socket graft can be used. This is where a graft material is applied to the socket of a missing tooth to stimulate growth and provide support. In cases where bone loss is more extensive a live bone graft may be necessary, taken from elsewhere in the body.

Causes of dental bone loss

Bone is maintained by the body as long as is deemed necessary, so if you don’t use it, you will lose it. A gap in your smile is not just an aesthetic issue – over time the bone that should be supporting that tooth will shrink, creating a sunken appearance and possibly leading to further tooth loss.

Tooth loss

If you have a tooth missing, your jaw will begin to lose bone density over time. Without the tooth and its roots attached, and the pressure applied by chewing, there is nothing to stimulate bone growth and the body begins to reabsorb the bone tissue.

Periodontal disease

Gums provide cover and protection for the bone around your teeth. In chronic cases of periodontal disease bacteria can gradually infect and damage bone and supporting ligaments, weakening them to the point that they can no longer support your teeth.

Bone grafting procedure

Your condition will be assessed using x-rays and 3D imaging technology. If you lack sufficient bone density and structure necessary for an implant we will explain to you what sort of bone graft and potential sinus lift (sometimes needed for bone grafts in the upper jaw) is required.

Any damaged teeth if present will be removed, and the bone graft material or bone sample will be applied. A period of approximately 4-9 months is needed before placing the implants and new teeth are attached. Your bone will develop around the titanium supports that have been placed, fusing together by a process called Osseointegration (derived from Latin osseus which means “bony”, and integrare “to make whole”) and creating a permanent and secure bond between the implant and your jaw.
