Résumé:
Dental arcades can have different shapes, which may relate to the
differential characteristics of each facial pattern, or even to the width of the face. The
facial analysis is extremely important in the diagnosis and orthodontic planning, since
the treatment of the malocclusions an improvement of the facial morphology.
Objective: The present study aims to evaluate the correlation between the facial
typology detected through the Vert index of Ricketts and the intra-arcos transverse
measurements. Method: The sample was composed of teleradiografias lateral and
models of studies in plaster of 90 patients above 18 years of age, belonging to the
specialization course in orthodontics of Funorte, in the city of Campina Grande. Were
divided into 3 groups, being 30 belonging to the mesofacial standard, 30 dolicofacial
and 30 braquifacial. The absence of permanent dental elements of the upper and/or
lower arcades, patients less than 18 years old and those with prior orthodontic
treatment were exclusion criteria. The registration of the Intra-arcos measures was
performed with a digital caliper of the branded Stainless (China) duly calibrated, and
the Vert index from the same radiological service. Results: Multivariate Analysis of
Variance (MANOVA) revealed no significant differences between facial types in
relation to DIC values (inter-canine distance), DIP (inter-premolar distance) and DIM
(inter-molar distance). The Pearson correlation showed that DIC values, DIP and DIM
showed each other positive significance level in all facial patterns. Conclusion: It
was concluded that there was in the sample, a direct relationship between the
transverse dimensions of the upper and lower dental arches and facial type of the
individual, but the significantly positive correlations between these measurements
indicated that its increase or decrease obeyed an independent proportion of facial
pattern, that is, when one tends to be higher, other measures also tend to increase.
