Orthodontic operations are divided into sub areas: Bone distraction and malocclusion surgery.
For jawbone deficiencies, there is a special procedure that can be used for stretching existing bone to stimulate bone formation in the resulting gaps. Natural bone growth is enabled by a tool called distractor, which has already been used for years in reconstructive surgery.
The distractor will be mounted into an opening of the jawbone, which has been surgically applied, and over a long period of time it will gently stretch the jawbone. The resulting gap between the bone and the moving bone block will be filled by bone tissue (callus) that the body creates, which later will turn into solid (hard) bone material.
This method is called distraction osteogenesis. It naturally forms new bone, so all teeth can be aligned equally next to each other. After three months the newly formed bone tissue is just as durable as the rest of the jawbone..
A change in the jawbone also has a significant impact on the outward appearance, because growth of the bone tissue also affects the muscles and blood vessels.
In a malocclusion dental arches aren’t aligning correctly, which can cause problems when eating and speaking. In addition, incisors are more susceptible to cavities and also the outward appearance may be affected.
To correct a malocclusion optimally from an aesthetic point of view, skin incisions inside the mouth are administered, so there won’t be any visible scars. The surgeon operates through those incisions, aligning the bone into an anatomically correct position in order to move the jaw forward or backwards – depending on the deformity.
After correcting the deformity, the bones will be fixated with small titanium screws and plates. In general the mouth can be opened and closed immediately after the surgery and there are also no restrictions to talking, eating and dental hygiene. In rare cases it might be necessary fixate, i.e. immobilize the jaw, in order to speed up the healing process.
