Abstract. Background. According to medical publications, sagittal abnormalities of occlusion are found in 1.2% - 42% of patients. Even in early stages of dentition development, sagittal abnormalities of occlusion are accompanied by substantial morphological, functional and esthetic disorders. Orthodontic treatment of occlusion abnormalities is aimed at restoring the form and size of dentitions, their articulation as well as improving myodynamic muscular equilibrium.

While planning treatment, one should keep in mind an important organizational question, i.e. how does a patient treat their own face, and what is their perception of possible facial changes after the orthodontic treatment.

The study purpose was to develop the algorithm and management approach to plan and predict orthodontic treatment and rehabilitate patients with sagittal abnormalities of occlusion.

Results. Preventive examinations of primary school children showed their need in orthodontic care and rehabilitation measures on posture alignment. Data analysis after timely orthodontic treatment showed reduced gaps pg-R in 43% patients, increased gaps in 21% patients, and zero changes in 36%. However, ratio of height of lower face segment and length of submental segment remained the same despite true increase of length of underlip and chin 2.84±1.07 (p<0.05).

Conclusions. The conducted examinations of children aged 3-12 years with distal occlusion of dentitions showed that musculoskeletal disorders and dentition abnormalities are formed even in pre-school age and deteriorate along with the children’s growth. The developed organizational and functional model of rehabilitation and alignment of posture and spinal deformities in children with sagittal abnormalities of occlusion has its positive medical and social effect.

Scope of application. The obtained results could be used by the Mother and Child Division of the Moscow Healthcare Department to develop preventive programs for schoolchildren.

Keywords: posture; occlusion abnormalities; program; prevention; rehabilitation.
