The maxillary (‘upper jaw’) sinuses are large air spaces which occupy the molar regions of your upper jaw. Often, the roots of your molars and even premolar teeth protrude into the sinus spaces. Following the loss of these teeth, the bottom of the sinus may descend, reducing the amount of bone to anchor implants. Such patients would often have to rely on wearing loose dentures, unless a sinus lift (also called augmentation or grafting) is carried out.
Bone height can be regained by means of elevating the floor of the sinus and allowing bone to grow in the space created. There are various ways of doing this. One technique involves making an incision, then raising a gum flap to allow us to make a small, oval shaped outline on the bone. This oval shaped bony piece is gently lifted inwards, to act like a trap-door. This creates a space that allows us to place some bone graft material. Simultaneous implant placement is sometimes possible, but more commonly they are then placed at a later date when the bone has regrown.
Another technique incorporates a small additional step, during the preparation of the channel for the implant. The bone channel is prepared until the thinnest layer of bone that is adjacent to the sinus floor is reached. Special instruments are carefully passed into the channel and gently tapped to elevate the small area of the sinus. Bone graft material is then gradually introduced through this channel. Implant placement can be placed simultaneously, if there is sufficient sound bone to stabilise the implant. Otherwise, after six months, when bone regeneration has occurred, implantation can be carried out.
Reduced need for invasive procedures
Materials And Science
Thanks to mushrooming scientific research in biomaterials from the 80s onwards, we are able to utilise clinically proven bio-materials and techniques for bone grafting.
This means that most patients can undergo implant treatment with little need for invasive procedures that require bone harvesting from extra-oral sites like the hip and ribs.
Furthermore, hospitalisation and general anaesthesia are usually not required.
Our Implant Treatment Philosophy
The continuous growth in the demand for implant replacements can be attributed to their high success rates. This is supported by human clinical research, dating back 50 years, which demonstrates success rates in excess of 95%. Our own positive experience with patients over the last 20 years, confirms this.
