Abstract

BELLUZZO, Regina Helena Lourenço; FALTIN JUNIOR, Kurt; LASCALA, Cícero Ermínio  and  VIANNA, Lucas Bacci Renno. Maxillary constriction: are there differences between anterior and posterior regions?. Dental Press J. Orthod. [online]. 2012, vol.17, n.4, pp. 1-6. ISSN 2176-9451.  http://dx.doi.org/10.1590/S2176-94512012000400009.

OBJECTIVE: To evaluate the transverse constriction of the maxilla in both anterior and posterior regions, using Korkhaus analysis and to check whether there were any statistically significant differences within its values. METHOD: The sample comprised 341 study models. The study models were randomly selected from previous cases, without gender, age and malocclusion restrictions. The models were submitted to Korkhaus analysis. Data from these models were subjected to statistical analyzes in order to evaluate differences in anterior and posterior regions. RESULTS: The transverse discrepancies were statistically significant (p<0.001) with a greater constriction in the anterior region (mean -2.84 mm). CONCLUSION: The results showed that the differential diagnosis is very important and the treatment plan may be adapted to specific therapy focusing in a greater expansion in the anterior region.
