The main reason of the deformation of the lower jaw is ankylosis - disease of the temporomandibular joint, leading to a serious restriction of movement (up to complete immobility) of the lower jaw. The causes of the disease, as a rule, are arthritis, mechanical injuries, and acute infections or birth injury. Infection can penetrate into the joint through the bloodstream (scarlet fever, diphtheria, gonorrhea, etc.) or in case of inflammatory diseases, as well as be caused by injury. The main goal of treatment that offers Oral Surgeons in North Carolina is restoration of mobility of the mandible, and normal shape of the face. If necessary, surgical treatment of ankylosis of the temporomandibular joint is accompanied by an orthopedic and orthodontic treatment to restore the normal shape of the dental arches and correct bite.
