Effect of Double Transpalatal Arch During Extraction Treatment of Class II Malocclusion

Category : Malocclusion
Languages : en
Pages : 42
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.
