For children, the loss of chewing teeth is one of the main causes of the formation of dental anomalies. The age of the child at the time of premature removal of baby teeth, the timing of eruption of permanent teeth, the number of missing teeth and the intensity of the carious process, as well as the functional group of destroyed or removed temporary teeth are essential for the formation of maxillary deformities of varying severity (Gayazov A.R., 2007). Early removal of temporary and permanent teeth occurs most often due to complicated caries (Gunaeva S.A., 2006; Gayazov A.R., 2007; Ikromova G.D., 2007) and is the main cause of the development of deformity of the dentition and bite (Kurlandsky V.Yu., 1974; Vasilevskaya V.F., 1990; Bychkov V.A., 1994; Hansson O. A., 1996).
