There are a variety of different types of malocclusion or misalignments of the teeth, arising from an unfavourable position of the maxilla, the mandible, or a combination of the two. The individual components of the jaw may be too long, too short, too narrow, too wide or asymmetric. This can lead to functional or aesthetic limitations that create the desire or the need for correction.
Corrective treatment requires teamwork. Since jaw malformations are usually accompanied by misalignment of the teeth, the treatment is carried out in close collaboration with an orthodontist. The specialists will analyse the situation together, based on 3-D x-rays, plaster models and images, and create an appropriate individual treatment plan. In the first phase of treatment, the necessary conditions are created using appropriate braces or other orthodontic appliances, so that the surgical correction can then be carried out. New developments mean that the appliances on offer today are very discreet or even invisible, so there is no need for any cosmetic concerns about the pre-surgical orthodontic phase.
Modern and well-established surgical techniques for the correction of jaw malformations (dysgnathia)
The surgical techniques for the correction of dysgnathia (called osteotomies, meaning procedures involving cutting through the bone) are as diverse as are jaw malformations themselves. Many of these have been in use for decades and have helped countless patients worldwide.
The Le Fort 1 osteotomy allows for the tooth-bearing area of the maxilla below the nose to be cut through and mobilised, for example. If necessary this can be further subdivided (segmented), brought into the correct position and fixed using small screws and plates.
Sagittal split osteotomy also allows for repositioning of the tooth-bearing region of the mandible, which can then be advanced or pushed back as needed to correct the malocclusion.
Using wing osteotomy of the mandibular rim, in a procedure called chin wing osteotomy which was developed at our centre, the profile can also be influenced such that, regardless of dental movement, the best possible result is achieved from both a functional and aesthetic point of view.
