Book Description
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

Book Description
Introduction: Anchorage and vertical control are some of the limiting factors in orthodontics, and their control is essential for successful orthodontic treatment. The purpose of this retrospective cephalometric study was to quantify the anchorage and vertical control capabilities of the double TPA by comparing Class II patients treated with full fixed appliances (Roth prescription - GAC 022x028 Slot), extraction of maxillary first bicuspid and utilizing double TPAs on first and second molars to a control sample of matched untreated Class II patients. Methods: Pretreatment and post treatment lateral cephalograms were analyzed of 20 patients (10 male and 10 female) from the same orthodontic practice with skeletal Class II malocclusions, characterized by hyperdivergent growth patterns. All of the 20 patients had maxillary first premolar extractions and double TPAs on the maxillary first and second molars. Space closure was done without headgear, utilizing only double key-hole closing loop archwires. The experimental sample was matched to controls from the Michigan and Bolton Brush growth studies. 12 cephalometric variables were identified to evaluate the effect of double TPAs on various skeletal and dental parameters including anchorage and vertical control. Results: Upper first molar horizontal movement in TPA experimental group: U6-PT Vertical=0.9mm, 6-PTV UMKC=1.2mm and H Perp to mestal U6-0.6mm, moved less forward compared to controls. Upper first molar vertical movement in TPA experimental group: U6-PP measurement in the TPA group was 1.9mm less compared to controls. U6-SN measurement was statistically insignificant between the two groups. Conclusions: Double TPAs were shown to effectively hold the anchorage and control the vertical in the treatment of skeletal Class II hyperdivergent patients.
