Bone Grafting

In some implant cases it may be necessary to improve the volume or quality of bone with bone grafting. This procedure is a surgical procedure that replaces missing bone with a material called a bone graft.

The graft material materials most commonly used are autogenous bone (patient’s own bone) harvested from the oral cavity and synthetic or bovine bone substitutes.

Whilst grafting procedures may sometimes be required in advance of total rehabilitation, in many cases it is possible to carry and advantageous to to perform the grafting at the same time as implant placement.

TYPES OF BONE GRAFTING

Inlay Graft

Used at the time of extraction of teeth, the graft is placed within the residual socket to preserve the shape of the jaw bone and avoid bony resorption. It is a routine procedure in cases requiring the removal of teeth.

Onlay Graft

Where bone width is lacking, this procedure can restore bone volume by laying the graft material on the surface of the jaw.

Sinus grafting

The sinus is an airspace in the upper jaw that can be utilised for bone grafting. Being a protected space, the graft is less susceptible to external influences, such as pressure from a denture, and is today regarded as part of routine implant treatment when restoring vertical bone height in the back of the upper jaw, for the simultaneous or subsequent placement of implants. A bone material called Bio-Oss is used in combination with your own bone to help develop new bone during this procedure.

Bio-Oss is a safe and effective bone graft material from specifically processed bovine sources. Because of its similarity to human bone, it is highly successful in helping new bone to form.
