The article is devoted to the definition of the terms of eruption of permanent teeth, depending on the type of bite in orthodontic patients at the age of 6 years. Cutting teeth is one of the important indicators of normal development of the tooth-jaw child’s system. A dental and orthodontic review of 144 6-year-old patients who sought treatment for orthodontic pathology was conducted. They evaluated the presence of the first permanent molars, central and lateral incisors. The examined children were divided into groups according to the available bite pathology according to the Engle classification. Studying features of permanent teeth eruption in children 6 years old with bite pathology showed that 10.3% of patients had no first permanent molars, that is, every tenth orthodontic patient had a lag behind the physiological norm of cutting the first permanent molars on the lower jaw. More than a third of children with bite disorders (34.33%) at 6 years of age do not have the first permanent molars on the upper dental artery. The first top molars are found in 1.68 times more often than the case, that is, there is an asymmetry of prorising the first permanent molars. It was established that the eruption of the first permanent molars occurs more actively with II cl. by Engle. At dentofacial anomalies I kl. аccording to Engle, the process of cutting not only the first permanent molars, but also central and lateral incisors is slower. Depending on the pathology of bite, the process of pricking central incisors in 6 years in 80% of orthodontic patients on both jaws proceeds more actively with II cl. by Engle The parity of the eruption is not disturbed only on the upper jaw at I kl. and ІІ class by Engle.
