Abstract
dc.description.abstract
In orthodontics and maxillofacial surgery, dentoeskeletal diagnosis is essential for treatment planning.
Traditionally, this diagnosis is carried out using cephalometric analysis based on the comparison of distances and angle
measurements. While this method successfully discriminates within group extreme types of malocclusions, it usually does
not distinguish the intermediate ones, which leads to different diagnoses for the same phenotype. Moreover, the linear
nature of cephalometric data does not allow to partition shape and size components. In order to study the variation of
dentoskeletal pattern in Chilean population, in the present study standard methods of geometric morphometrics to a sample
of 150 lateral telerradiographs of classes I, II division 1 and III were applied. We found that classes I, II and III show
statistically significant differences associated, to a greater degree, with a sagittal maxillo-mandibular relationship, and to a
lesser degree with a vertical growth pattern, allowing positive discrimination of intermediate phenotypes. We conclude that
tools of geometric morphometrics constitute a complementary and effective approach to address unresolved problems
associated with conventional cephalometric analysis.
