Once our teeth are lost, the surrounding supporting bone gradually shrink. To increase the volume of bone available at the site of dental implant placement, we may require to perform a grafting procedure before, or at the same time of your implant surgery. The type of bone graft required will depend on each individual implant recipient site. In general, larger and more complex defects require block bone grafts which will require longer treatment time to allow the bone to properly unite with the underlying jaw bone. Smaller deficiencies can be augmented at the time of implant placement.
Replacing lost teeth at the back of your upper jaw may require a sinus lift procedure, which aims to increase the available bone height and/or width to support your implant. There are several ways this procedure can be done. Just like bone grafting, the method and the type of bone used will depend on how much existing bone you have at the implant site.
