ABSTRACT

Introduction. The Maximum Bite Force (MBF) is a functional indicator of the masticatory system that indicates the force in kilograms force (Kf), which the dental teeth apply during chewing by means of the mandibular lifting muscles that reach high forces over short distances. There is bibliographic evidence that MBF is related to facial morphology. Objective. To identify the relationship between the Mesofacial-Brachifacial-Dolichofacial Biotypes and the MBF. Methodology. Cross-sectional, descriptive, prospective, observational study 60 young adults, both sexes, who attended the Masticatory Physiology Laboratory of the Universidad Autonoma Metropolitana Unidad Xochimilco (Mexico City) and voluntarily agreed to participate in the study. They were divided into three groups of 20 subjects each: A) mesofacial, B) brachifacial and C) dolichofacial. The facial type was measured and recorded with the Truper® digital calibrator, as well as the MBF of each young person using the T-Scan® EH-2 (Research) system, since it is an instrument that allows to evaluate the entire occlusal arch, without interfering in the interoclusal distance. Results. Mean age 22 ± 3 years and percentages of women 55% and men 45%. The Kf of the three groups: A) 46.07 Kf, for group B) 36.85 Kf, and group C) 30.98 Kf. With the ANOVA test, in the statistical program SPSS version 22. Statistically significant differences were found between A and C with a p = 0.003, between group A and B the p = 0.05 and no statistically significant difference between group B and C with a p = 0.275. Conclusion. It was determined that subjects with mesofacial and brachifacial biotype have the same statistical significance of MBF, therefore the null hypothesis was accepted, in which the brachifacial biotype is not the one with the greatest force in bite Kf.
