Abstract:
The purposes of this study were to observe the compensation pattern of human female adults with openbite tendency and to provide the decision criteria of the diagnosis and treatment planning for those patients. Fifty patients with anterior openbite and fifty-five patients without anterior openbite patients were selected as a control and a test group. ODI of the all patients was below 66. Mean ages of the control and the test group were 23.88+/-4.53 and 24.7+/-6.20 years, respectively. Lateral cephalograms were taken and forty-one variables were measured. To identify the morphological differences between the groups, statistical analyses were performed. Statistically significant differences were found in the measured variables of lower face height, N-Me, ANS-Me, ANS-Me/N-Me ratio, Mx1-SN, Mx1-FH, Mx1-NA(mm), Mx1-APo, PP to Mx6, Mn1-NB(degree), Mn1-NB(mm). The test group showed decreased lower face height, N-Me, ANS-Me, ANS-Me/N-Me ratio, more uprighted and retruded maxillo-mandibular incisors. Overeruption of the maxillary first molar was found in the control group.
