Recently, the city of Samarkand has implemented a set of measures aimed at improving, diagnosing and treating vertical anomalies, namely open bite, and at the moment many scientists and practitioners have begun to study more deeply the factors leading to the development of this anomaly. In clinical practice, etiological factors, endogenous and exogenous factors, as well as the living conditions of this patient, taking into account the age of the patient, are of particular importance. We carried out preventive measures for children aged 6 to 15 in 37 patients with an open bite.[1,2]

    Taking into account all aspects of this anomaly, we set ourselves the task of diagnosing patients with open occlusion using modern methods, taking into account their age and type of anomaly.

 open bite is considered as an independent form of dental anomalies, and can be combined with other disorders in the transversal or sagittal direction.[3]

According to the literature, an open bite occurs in 62% of cases together with the mesial ratio of dentition

An open bite is a serious anomaly of the maxillary system. According to the results of a survey and observation by Nigmatova R.N., Shaamukhamedov F.A., Nigmatova I.M. (2017), open bite was 1.4% among children aged 3-6 years. According to L.P. Grigoriev (1995), 1.12% in children aged 7-16 years. 2.7% in the distribution of anomalies of the maxillary system.[5,6].

However, a number of researchers claim that by the age of 9-10, the frequency of open bite decreases, which is associated with the elimination of bad habits that contribute to the development of the anomaly, as well as with the normalization of respiratory and swallowing functions. In later adolescence, there may be a repeated increase in the prevalence of open bite due to late bone growth in the facial region of the skull [4].
