The influence of lingual location of the braces with Bite Planes, in the anterior upper teeth on the elements of the dentofacial complex, remains one of the important subjects for study. The aim of this work, is to evaluate the probability of distocclusion in the frontal area of dental arches, gum recessions, roots resorptions, bone density and the balance of the masticatory muscles in the treatment of patients with distal occlusion by fixed lingual devices. Material and methods. The study included 50 patients, of which 38 were female and 12 male. We studied the effect of occlusal loading on the activity of masticatory muscles, echo-density of anterior alveolar bone and the condition of the apical and periapical tissues. Results. The presence of the Bite Planes of lingual braces, does not lead to osteoporosis in bone tissue in the anterior jawbone, due to the decrease in the overall of bioelectrical potential of the masticatory muscles and reduction of the activity of the temporal muscle and does not cause vertical disocclusion in the anterior dental arch at the finishing stage of treatment. Gum recession and roots resorptions, was observed in patients regardless of the presence of the Bite Planes on the lingual braces. Conclusion. The decrease of general electric activity of mastication and proportional activity of the temporal muscles, in cases of stabilisation of the level of occlusal load on the canines and incisors at the initial stages of orthodontic treatment, contribute to the formation of biodynamical balance and stability of the results of orthodontic treatment. Lingual location of the braces with bite plane does not cause pathological changes of the elements of the dentofacial complex.
