In cases where the front teeth are too far forward or backward, some sounds cannot be pronounced correctly and speech problems arise. In some cases, problems can be seen not only in the teeth but also in the skeletal system. The patient cannot fulfil chewing and speaking functions because the upper and lower jaw or both are not in the correct position. Aesthetically significant skeletal asymmetry can also be seen. In this case, in addition to orthodontic treatment, a surgical procedure covering the upper and lower jaw is performed. Thanks to this treatment called orthognathic surgery, it is ensured that individuals whose growth development is completed have the correct jaw and tooth closure and the missing functions are corrected.
