In children, as well as in adults, removable prostheses are used, both partial and complete, but elements of orthodontic technology are often added to the basis of a removable prosthesis.
Factors that determine the correct formation of the dentoalveolar apparatus are as follows:
► biological potency to growth;
► the function of chewing;
► tooth eruption.
Proper development of the digestive tract is an important factor in the formation of the chewing apparatus of a child.
The preservation of deciduous teeth is very important for the growing body of a child, as they affect the formation of the bite, the formation of the muscular apparatus and elements of the temporomandibular joint.
Disturbance of occlusion in childhood is a determining factor in the development of pathological changes in the temporomandibular joint, in the facial skeleton, adjacent tissues and organs, since all these formations are closely related to each other in their development. The severity of pathological changes will depend on the time of developing occlusive disorders. The earlier disturbances develop, the more serious the changes caused by them will be since the dental system of a child does not yet have the stability that is present in adults.
S.V. Dmitrienko et al. (1994), proposed a clinical and radiological classification for the systematization of dentition defects, their diagnosis and choice of treatment method, taking into consideration the topography, extent and localization of defects. All defects of dentition in children are divided into five classes with divisions.
Class I - Defects in the anterior part, limited (restricted):
► division 1 - of deciduous (primary) teeth;
► division 2 - permanent teeth with unformed roots;
