What is orthognathic surgery?

Orthognathic surgery stipulates a series of operations, aimed at correction of occlusion and external symmetry of the face. These manipulations can lead to the results, unachievable by braces: to shorten or lengthen the jaws, to move them in the desired position, to adjust the size of a chin. It should be noted that during the osteotomies not only the bony structures, but also the soft tissues underwent transformation; in the result, facial features become correct and more attractive, and appearance is really improved.

In what cases occlusions need surgical correction?

Orthognathic surgery is used in cases, when conventional orthodontic treatment with brackets or such orthopedic devices as crowns and veneers appeared to be useless, or led to worsening of the patient's conditions. It is about notable skeletal deformations of second and third class, expressed in abnormal size of the jaws and chin. For example, orthognathic operation is indicated in case of pragmatic occlusion, i.e. small lower jaw, causing a second chin, at that some teeth do not occlude with the opposite ones. Unfortunately, many orthodontists refuse to accept that treatment of such dento-maxillary anomalies using braces only shall never release a patient from the speaker forward chin or gingival smile, apart from the fact that only orthodontic treatment in case of skeletal deformities often leads to teeth luxation or pathologies of the temporomandibular joint (TMJ). The last mentioned could cause GIT disorders, head and back pains and other unpleasant complications. .

Should a patient be specially prepared before surgical correction of occlusion?

Before the treatment starts, the doctor should define the proper maxillofacial parameters required for synchronic work of the temporomandibular joint, harmonization of face features and ensuring maximum quantity of contact between the teeth. For that the doctor is assisted by special Dolphin software for 3D-simulation. It allows you to create a template, which is then at orthognathic operation to achieve a 99% match of planned result with obtained one. This is very important because when it comes to the appearance of a person, it is necessary to plan the treatment properly and achieve the effect expected by the patient.

What are the contraindications against orthognathic surgery?

Firstly, occlusion should not be surgically corrected in patients with unformed jaws, i.e. children and adolescents. Secondly, the operation is prohibited in cases of blood coagulation disorders, cardiovascular pathologies, diseases of endocrine and skeletal systems, cancer tumors in facial and oral areas, some forms of diabetes and mental illness. In addition, we do not operate patients with correct occlusion and beautiful face features, who demand to correct a defect imagined by them. Orthognathic surgery really transforms people; they become younger and more attractive. However, we can't change the appearance of a person completely by just putting the jaw in its correct position. Unfortunately, not all potential patients understand this! .
