Eighty-five (45 male and 40 female) skeletal Class II untreated subjects with low (< 27 degrees ), average (27 degrees - 36 degrees ), and high (> 36 degrees ) mandibular plane angles (MP-SN) were selected from the Bolton-Brush and the Burlington Growth Studies. Cephalograms of each subject at ages 9 and 18 were traced, and 28 parameters were measured. The(More)
Sixty-eight (36 male and 32 female) untreated skeletal Class I subjects with low (< or = 27 degrees ), average (>27 degrees - <37 degrees ), and high (> or = 37 degrees ) mandibular plane (MP-SN) angles were selected from the Bolton-Brush and Burlington Growth Studies. Cephalograms of each subject at ages 9 and 18 were traced, and 28 parameters were(More)
The objectives of this study were to investigate if a relationship exists between dental arch width and the vertical facial pattern determined by the steepness of the mandibular plane, and to examine the differences in dental arch widths between male and female untreated adults. Lateral cephalograms and dental casts were obtained from 185 untreated(More)
ooth anomalies in the permanent dentition are rare and often incidental findings in routine orthodontic care. Occasionally, however, an anomaly may have a considerable impact on orthodontic treatment planning. In such a patient, advanced three-dimensional imaging modalities such as cone-beam computed tomography (CBCT) can provide critical assistance, as the(More)
