Ninety lateral cephalograms of adult subjects were included and classified by skeletal malocclusion (class I, II and III) and facial patterns (dolicofacial, mesofacial and brachyfacial).
To further assess such differences between groups, we once again performed the analysis comparing the mesofacial versus brachyfacial and then the mesofacial versus dolichofacial groups.
TPS graphical display of shape differences between meso and brachyfacial groups revealed a decrease in lower facial dimension, but the results were not statistically significant.
Analysis and discussion of the results achieved in this study allow us to conclude that no statistically shape significant differences were found when comparing the mesofacial and brachyfacial groups.
In this sense, indigenous populations of brachyfacial biotype characterized by wider maxillary and squarer jaws, have craniofacial structure that has encouraged the development of greater bite force, compared with individuals having dolichofacial biotype (own mestizos and African descent) (Bedoya et al., 2012).
It has been reported that dolichofacial subjects need greater muscular effort during mastication as compared to meso- and brachyfacial subjects.
However, a tendency for there to be a relationship between long-faced subjects and unilateral chewing is suggested by the data, given that 50% of the dolichofacial group presented chewing side preference, as opposed to meso- and brachyfacial groups, of whom 30.8% were unilateral chewers.

The facial skeleton grows in a forward and downward direction.15 In a "mesofacial" growth pattern, there is a relative harmony in these two directions, leading to a facial profile which is described cephalometrically by a 90(3) facial axis angle.15 Brachyfacial is the term used to describe the person with a short anterior face height and a wide face, cephalometrically >93 facial axis angle.4
Nanda et al also noted that the amount of time of growth differed between different facial types.20 It was shown that brachyfacial patients exhibited a prolonged period of facial growth in contrast to dolichofacial patients.
Based on angular measurements, the subjects were classified as dolichofacial (SN.SGn > or = 70.1[degrees]), mesofacial (SN.SGn [less than or equal to] 70[degrees] and [greater than or equal to] 64.1), and brachyfacial (SN.SGn < or = 64[degrees]), using the measurements suggested by Steiner (1959), and those evaluated by Riedel (1952), namely, dolichofacial (SN.GoGn > or = 37 [+ or -] 1[degrees]), mesofacial (SN.GoGn between 27[degrees] and 37[degrees]), and brachyfacial (SN.GoGn < or = 26.9[degrees]) as seen in Figure 1.
In order to verify whether there was an association between the facial skeletal pattern (dolichofacial, mesofacial, or brachyfacial) and dental arch morphology (square, oval, or tapered), the chi-squared test was used.
