Abstract

GARBUI, Ivana Uglik et al. Cephalometric assessment of vertical control in the treatment of class II malocclusion with a combined maxillary splint. Braz. oral res. [online]. 2010, vol.24, n.1, pp.34-39. ISSN 1806-8324.  https://doi.org/10.1590/S1806-83242010000100006.

Vertical control is one of the primary objectives sought by orthodontists when treating malocclusions in hyperdivergent individuals. This investigation aimed at assessing vertical control, by cephalometric measurements, during the treatment of Angle Class II Division 1 malocclusion. Thirty cases, selected from the files of the São Leopoldo Mandic Dental Research Center, Brazil, of subjects with Angle Class II Division 1 malocclusion and facial hyperdivergence, were used in this study. The patients were treated using a combined extraoral appliance during a mean treatment time of 1.1 years. Pre- and posttreatment cephalometric measurements were compared to assess vertical control. The results were submitted to ANOVA (p = 5%). The ANOVA test revealed no statistically significant difference between the pretreatment and posttreatment values of OP (Occlusal plane angle) and SN.MP. While there was a decrease in Y-axis, FMA, and PP.MP, there was an increase in SN.PP, Co-Go, AFH, PFH, and FHI. It was concluded that the divergence in the facial lower third of the patients did not increase, suggesting that the combined extraoral appliance with the line of force application directed to the resistance center of the maxilla was effective in treating Angle Class II malocclusion in hyperdivergent subjects.
