Mordida abierta anterior y deglución atípica en niños de 4-9 años. Clínica UCSG Semestre A-2018.

Abstract

Introduction: Anterior open bite frequently presents aesthetic and functional alterations in mastication, phonation and swallowing. The deficient function of the masticatory system and the irregularities of facial growth have multifactorial origin, among them the presence of oral habits. Variations in swallowing occur especially in the anterior region, regardless of the dentoskeletal configuration of the individual. There is controversy between if they are related to each other or not. Objective: To determine the relationship between atypical swallowing and anterior open bite in patients from 4 to 9 years attended in the dental clinic of the UCSG in the semester A-2018.Materials and Methods: A descriptive and transversal study, in which manual cephalometric tracings were performed from 69 pediatric patients who attended the orthodontic clinic of the Catholic University of Santiago de Guayaquil and met the inclusion and exclusion criteria. The studies that were used for the cephalometric analysis were Björk, Ricketts and McNamara. Results: 60% of the patients presented tongue thrust swallowing and didn´t have anterior open bite. In this patient, the gonial angle and the mandibular plane angle were mostly normal. However, there was a percentage of increased values. The anterior and inferior facial height showed decreased. Anterior open bite values were irrelevant. Conclusion: It can be concluded that, for this study group, anterior open bite had no relation to the tongue thrust swallowing. Anterior open bite subject didn´t show skeleta anomalies.
