Asociación entre el biotipo facial y la clase esqueletal en pacientes entre 11 y 30 años atendidos en la Clínica de especialidades de ortodoncia UDD entre los años 2015 y 2020

Abstract

Introduction: In orthodontics, concordance between skeletal class and facial biotype is important to establish a good diagnosis and treatment, in order to correct problems of esthetics, mandibular dynamics and malocclusions. Objectives: To evaluate the association between facial biotype and skeletal class in Chilean patients aged 11 to 30 years who were seen at the orthodontic specialty clinic of the UDD. Methodology: A cross-sectional study was carried out analyzing the association between facial biotype and skeletal class of patients seen at the CESP. A descriptive analysis of the absolute and relative frequencies of the different categories and their combinations was performed. The statistical association was determined through the X2 test. Results: 290 participants were included, 55.5% female, with a mean age of 19.6 years. The most prevalent biotype was dolichofacial and the skeletal class was class II. As for the association 67 patients were class II and dolichofacial, being the most frequent association. A 57.24 % did not present concordance. Discussion: Normality based on facial biotype and skeletal class was not predominant, this is related to malocclusion, esthetic and TMD problems. Interceptive therapy and orthognathic surgery are options to treat dentomaxillary anomalies depending on factors such as age and severity of the condition. Conclusion: 57.24% of the population does not present a concordance between facial biotype and skeletal class, so a correct diagnosis, planning and treatment plan are essential to obtain favorable results.
