Abstract
Objective Applicating nickel titanium flat and round wire in low fangs extraction crowding cases.Researching the influence of dental arch and the occlusion. Methods 40 cases were divided into flat and round wire groups.they were low fangs crowding cases of class Ⅰ Osseous neutronclusion,extracted four first premolars, treated by nickel titanium flat and round wire and active-wing appliance.low fangs were neaarranged.Study model were analysed before and after treatment. The measurement data had statistical analysis,the effect were observed of dental arch width and length. Results Flat wire group:widths of maxillary canines decreased,The upper second bicuspid increased,The upper molar had no change.The distance maxillary incisor and molar to palatal wrinkle had no change.round wire groups:widths of maxillary canines decreased,the upper second bicuspid and upper molar increased. The distance maxillary incisor to palatal wrinkle increased.the distance molar to palatal wrinkle had no change. Conclusion Nickel titanium flat wire and activewing appliance can treat low fangs extraction crowding cases.That can adjust the morphology of dental arch,preserve the stability of functional occlusal plane,Control the incisor protrusion.reduce the new teratogenesis,decrease the speed of orthodontic treatment,short the period of treatment,Clinical curative effect is good.关键词
