The insertion of dental implants requires sufficient bone to hold the implant in place and ensure long term success. Where teeth are missing, the jaw bone degenerates and is absorbed over time. This situation leads to depleted bone (in terms of quality and quantity) and even missing bone, so that no dental implants can be inserted.
In such cases, bone grafts are required during or before the implant procedure.
Today, we have various means of building bone at our disposal. These treatments make it possible to insert dental implants of the correct length and diameter, while also permitting optimum functional and aesthetic restoration. There is a wide range of bone grafts and techniques for implanting them.
Dr. Schwartz-Arad’s long experience means that she can help you choose the most suitable bone graft and implant technique for your particular case.
Recent technological developments combine the use of various materials that stimulate and propagate the production of bone by the patient’s own body cells. Bone substitutes can be taken from a number of sources: the patient’s own body, other animal or synthetic sources.
The sinuses are air spaces located over the upper jaw and the back teeth (to right and left). After the extraction of teeth from the upper jaw, there is a process of bone absorption, which causes the floor of the sinus to “approach” the oral cavity. This makes the insertion of dental implants more difficult because there is insufficient bone to anchor the implants. (If we try to insert an implant in this situation, it will break through the sinus floor directly into the sinus.) In order to overcome this problem, the sinus floor must be pushed upwards (further away from the oral cavity), so that bone replacement can be implanted in the extra space, giving us sufficient bone height to insert the dental implants.
Dr. Schwartz-Arad has been performing this procedure successfully for many years. The results are relatively pain-free, can be successfully predicted, and permit the insertion of dental implants in the upper mandible where previously there was insufficient bone.
In certain cases, the maxillary arch has been significantly absorbed and bone grafts are needed to restore the height and depth that have been lost. This procedure is usually done under general anesthesia, using autografts – bone taken from the patient’s own body, generally from elsewhere in the mouth (most commonly from the chin area or behind the wisdom teeth), is implanted and fixed in place.
