Abstract:
1 5 cases,5 males and 1 0 females,aged 1 6-26 years,with ClassⅡdivision maxillary mild to moderate protrusion were includ-ed.Damon III appliance was used to arrange the upper and lower dentition.Stainless steel micro-screw implants were implanted in zygomatic crest to provide the best bone anchorage,stainless steel rectangular wire was used for maxillary complete dentition continuous ligation and maxillary teeth distal movement.X-ray cephalometry study showed that U1-NA(°)reduced by 2.51 ±1 .52(P<0.01 ),U1-NA(mm)re-duced by 4.56 ±1 .25,UL-EP(mm)reduced by 2.21 ±1 .83,U6E-PTV(mm)reduced by 2.93 ±1 .1 7,U6A-PTV(mm)reduced by 1 .56 ±0.95,SNA(°)and the mandibular parameters were not significantly changed(P>0.05),centric jaw relation of bilateral molar was obtained.
