Combined orthodontic surgical treatments
If an element does not want to break through, it can be surgically released by the surgeon. Upper cuspidates in particular are often retired. After making a mucoperiostal fold, bone is removed until the element is visible. A bracket is then cemented onto the glaze. A wire or rubber band can then be attached to this and the cuspidate can be guided in the dental arch in this way (see figure below).

If a grown-up patient wants to have an abnormal jaw position corrected, this is no longer possible with orthodontic equipment only. The growth of the body (and with that a possible correction of the jaw position) has ended. A combined orthodontic-surgical approach is then the only option.
A class III jaw relation is also difficult to treat orthodontically. Sometimes an attempt is made to improve the situation with a cleat, which is attached to the back of the head with an elastic band. However, surgery is usually performed later in life.
These combined orthodontic-surgical treatments take place in a multidisciplinary collaboration between orthodontist and surgeon. The orthodontist sets the elements with orthodontic equipment prior to surgery in such a way that the surgeon can place the jaws on top of each other as much as possible during the operation. After the operation and healing phase, the orthodontist continues the treatment to arrive at the final state of the elements.
An upper and lower jaw and / or chin can be placed forwards, backwards, upwards or downwards. The jaws can also be widened. Thanks to these options, all jaw position deviations can be corrected.
An upper jaw displacement is called a Le-Fort operation. This is, depending on the extent of the part of the upper jaw being moved, a lefort I, II or III operation. You can find an explanation of Le-Fort operations in chapter '' Fractures - Oral diseases, dental and facial surgery ''.
