Cephalometric Differences In Children Treated With Two Extraction Patterns In The Mixed Dentition PDF Download

The aim of this study was to compare cephalometric changes in skeletal and dento-alveolar parameters in cases treated by these two different orthodontic techniques. This was to be established by calculating and comparing the pre- and post-treatment cephalometric variables of cases treated with these techniques by looking at the skeletal and dento-alveolar measurements. Thirty Tip-Edge and thirty edgewise treated cases that had class II malocclusion, had extraction of four premolars and were treated with Class II elastics were selected. The gender distribution between the Tip-Edge and the edgewise techniques were 47% and 60% respectively for females. For males it was 53% in Tip-Edge and 40% in the edgewise techniques. The mean ages were 17.8 for Tip-Edge and 13.8 for edgewise techniques. The pre- and post-cephalometric radiographs were collected and the landmarks used were digitized using a Dolphin 10.5 Imaging and management solutions program
