When others say "not enough bone" we say "we have the solution".
Distraction osteogenesis is a well-known orthopedic technique that has been adapted for use in oral and maxillofacial surgery to increase the size and volume of the bone in the maxilla (upper jaw). This method allows for the placement of implants in cases where conventional dental implant procedures are not possible due to insufficient bone volume. Alveolar distraction osteogenesis is a surgical technique designed to increase bone volume in the maxilla in cases where there is not enough bone for dental implants. The method is based on the principle of bone lengthening, in which the surgeon creates a gap between two segments of bone and gradually expands them, allowing new bone to form gradually in the gap.
The surgery begins with local anesthesia. The surgeon then performs a separation of two bone segments in the maxilla and uses a specialized device called a “distractor” to gradually expand the gap between the two bone segments. In the days following the surgery, the patient operates the distractor every day manually, gradually expanding the bone and allowing new bone to form in the gap between the two segments.
The distractor device is typically made of titanium. It is a rigid device with an activation handle, and it can be fixed to the bone in the maxilla with special screws. The distractor allows for precise control of the distance between the two bone segments and the direction of bone growth, which are critical for the success of the procedure.
When the distractor is activated, the gap between the two bone segments in the maxilla widens, and new bone begins to form in the middle. This process can take several days to weeks, depending on the size of the gap. Operating the distractor daily during this period gradually increases the gap between the bone segments, and bone regeneration progresses until the newly formed bone becomes functional and strong.
Distraction osteogenesis is highly efficient for increasing bone volume in extreme cases of bone deficiency in the maxilla. It can provide a solution for patients who were previously considered unsuitable for dental implants. Unlike other bone grafting methods, this technique does not require taking bone from another area and transferring it to the maxilla, reducing the associated pain and discomfort for the patient. Additionally, there is a lower risk of infection with this technique.
Distraction osteogenesis is a highly effective surgical procedure but is considered complex and precise. If not performed correctly, it can result in damage to the maxilla, including nerve injuries or fractures. Skilled surgical expertise is required to perform this procedure safely and accurately.
