ABSTRACT
Facial Harmony is one of the main goals of orthodontic treatment, and it is not always correlated with the attainment of cephalometric objectives. The purpose of this study was to evaluate two groups of subjects presenting a clinically balanced soft tissue profile using cephalometric radiographs. Thirty lateral cephalometric radiographs of white females, divided in two groups, one with excellent facial profile (Group 1), and the other with good facial profile (Group 2) were used. Student's t-test (P?< .05) was used to compare the cephalometric parameters of the 2 groups. Linear regression analysis was also performed between 1.NB and SnV-Pog and between AB horizontal and SnV-Pog'. Group 2 showed higher mean values than group 1 for ANB (p = 0.002), AB horizontal (p < 0.001), 1.NB (p < 0.001), and a lower mean value for SnV-Pog (p = 0.003). The higher the SnV-Pog value, the lower the 1.NB value, no matter what group was evaluated. For each 1 mm increase in SnV-Pog, a 0.61º decrease could be expected in 1.NB (p = 0.003). The higher the SnV-Pog value, the lower the AB horizontal value, although group 2 presented greater AB horizontal values. For each 1 mm increase in SnV-Pog, a 0.24 mm decrease could be expected in AB horizontal (p = 0.019). We concluded that women with good facial profile do not necessarily present the same cephalometric values, and facial analysis should be the main reference in planning orthodontic treatments and should be considered together with cephalometric analysis in an individualized way.
