| Summary: | The purpose of this study was to evaluate the relationship between
mandibular rotation with anterior and posterior facial height changes which were
treated with the Begg technique.
The study utilized lateral cephalograms taken from 30 female and 5 male
subjects, ranging from 17-25 years old with class II malocclusion skeletal type.
All subjects were treated by Begg technique preceded by extracting four first
premolars.
The lateral cephalograms were taken and measured pretreatment and
posttreatment. The angular measurement was used to evaluate Y-axis angle and
linear measurement to evaluate anterior and posterior facial height. Regresi and
Corelation by repeated measures analysis was used to the data analyze.
The result of the study indicated that there was positive relationship
between mandibular rotation with the anterior facial height changes (p < 0.05)
and positive relationship between mandibular rotation with posterior facial height
changes (p < 0,05). The conclusions was that each additional of Y-axis angle will
be the addition of the anterior and posterior face height. |
