The morphology of the craniofacial skeleton is influenced by the bite force, which is the most influencing factor in the determination of the facial biotype. Thus, the objective of this research was to obtain the maximum bite force (MBF) of molar and incisor teeth, and to connect them to four anthropometric indexes according to sex, and occlusal relationship. This study included a sample of 101 young people, between the ages of 18 and 25, with type I, II and III molar and incisor skeletal profiles. A portable force measuring device was used. The individuals were seated in orthostatic position and instructed to bite as hard as possible in normal maximum occlusion position. A caliper ruler and compass were used to measure. There were significant differences between both sexes, only in the molar region (p= 0,004). The values of the averages of all the class II individuals were higher. When connecting the MBF with the anthropometric indexes, there were only differences at the incisor tooth level with the mandibular ramus (IR) and the ziggo mandibular indexes (ICM) (p= 0,000, respectively). Furthermore, there were no significant differences (p= 0,486; 0,097; 0,154; 0,601; 0,196; 0,269, respectively) when connecting the MBF of the molar and incisor teeth and the anthropometric indexes, according to the occlusal relationship. We can conclude that according to sex, there were significant differences in the molar region. The subjects with a class II occlusal relationship presented higher values of MBF and higher values of anthropometric indexes. Significant differences were observed when connecting the MBF of the anterior tooth region with the IR and the ICM and there were no significant differences identified when connecting the MBF of the molar and incisor teeth, with the indexes studied according to the occlusal relationship.
