Gnathia comes from the Greek word gnathos, and means jaw. By dysgnathia we mean malformations of the jaw or masticatory system. These changes affect the positioning of teeth, occlusion, the bite as well as the formation of the jaws, and thus their position with relation to each other and within the whole skull. Jaw deformities can be either genetic or due to certain habits. This can cause functional problems and often aesthetic deficits as well. The major characteristics are dental malpositioning, with the chewing function incorrectly carried out, and teeth that are too closely positioned, leading to difficulties when cleaning teeth or overloading, leading to tooth loss. If the lips cannot be closed, this can cause a dry mouth, breathing through the mouth resulting in speech problems and a high susceptibility to colds.
Should mandibulary pain, insufficiently closed lips, incorrect chewing, neck and back ache, snoring or dysfunctional speech occur, treatment is indicated. These problems can occur at a later date with some patients. In this case you can get in touch with us at any time. Some patients are dissatisfied with their aesthetic appearance. To deal with these flaws, relocation surgery to the upper and lower jaw, and to the chin, is carried out. A concept is developed in close collaboration with the orthodontist and individually tailored to each patient. Concepts are worked out using clinical examinations, x-ray pictures, profile analysis, computer simulation and plaster models, in order to achieve a perfectly functional and aesthetic result.
Detailed planning increases the patient’s safety. Early treatment is carried out by the orthodontist, who ensures that the teeth are so placed that they can be ideally put into position in an operation. This phase lasts several months. In our clinic, preparatory measures for the operation are taken, after extensive advisory talks. During the operation itself, which is carried out under general anaesthetic, the jaw bones and/or chin are loosened, correctly positioned and refixed with titanium plates. After surgery a stay in hospital is necessary, the length of which depends on the extent of surgery. Dental care and oral hygiene are slightly restricted during this time. After the operation the orthodontist plays an important role again. He carries out the precise adjustment of the teeth, and thus the occlusive correction. In the case of pronounced muscular disbalance the consultation of a physiotherapist can prove useful. We recommend the removal of the titanium plates, which can be carried out in a relatively simple and small operation after at least 6 months.
Pictures show the development with a patient with inferior retrognathia (Angle class II).
Interested and/or affected patients can address themselves to the clinic at any time (Langerstraße 3, 81675 München); Dysgnathia surgery Thurs. 14.00 – 16.00; Tel. 089 41402929, private patients should report to the secretariat of Univ.-Prof. Dr. Dr. K.-D. Wolff, Tel. 089 41402921). You will be attended to and advised by competent staff in our clinic.
Picture 1: Patient with Angle class II (inferior retrognathia) after orthodontic treatment before surgery. Pictures show the position of jaw and teeth before the operation. The lower teeth are too far behind the upper teeth.
Picture 2: Same patient as in picture series 1, now with Angle class I (normal jaw relation) 4 weeks after surgery (lower jaw osteotomy). The correct relation between upper and lower jaw has been achieved.
