[The orthodontic treatment of traumatic occlusion in sagittal bite anomalies]

A total of 288 patients (100 females and 188 males) aged 25 to 60 with prognathic and progenic occlusion were examined and treated. Dentition deformations were revealed in 182 (63.1%) patients. Clinical and x-ray signs of traumatic occlusion were observed in 219 (76.04%) cases. Abnormal mobility of teeth was detected in 181 (79%) subjects with prognathic occlusion, dentogingival and osseous pouches in 164 (71.6%) subjects. Reduced height of occlusion was found in 68 (25.3%), dysfunction of the temporomandibular joint in 19 (8.2%) cases. Traumatic occlusion was observed in 38 of the 59 patients with progenic occlusion. In sagittal abnormalities of occlusion, traumatic occlusion was associated with dysfunctions of the masticatory muscles and of local circulation in the periodontium, which were recorded by electromyography and rheoparodontography. The treatment was carried out by therapists, surgeons, and orthodontists. Orthodontic treatment consisted in levelling of the occlusion surface of dentitions, orthodontic preparation of the maxillodental system, fitting with splints and prostheses. Remote results in periods from 1 to 3 years were good in 94.8% of patients.
