Abstract
Objective:To compare the intrusion effect on the maxillary incisors,rocking chair archwire and miniscrew anchorage were used to correct the adult angle Class Ⅱdivision 2 malocclusion. Method:18 adult patients with Class Ⅱdi-vision 2 malocclusion were chosen and divided into two groups randomly:miniscrew group and rocking chair archwire group. 9 patients in the miniscrew group and 9 patients in the rocking chair archwire group were analyzed for maxillary incisors in-trusion. The upper 1st molars displacement and the relative skeletal changes were analyzed in the horizontal and vertical di-rections in both groups. Result:In average,the treatment period was 7.2 weeks in miniscrew group and rocking chair arch-wire group was 12.8 weeks.Significant changes of overjet,overbite,U1-PP,U1-SN,U1-Stms were observed in two groups before and after treatment.However,there were significant greater changes in U1-PP (P <0.01),U1-Stms (P <0.01) in the miniscrew group than in the rocking chair archwire group and there were significant reductions in overjet (P<0.05),U1-SN (P <0.05).There was no significant difference in U6-PP and U6-SN. Conclusion:There were significant intrusion effect on the maxillary incisors by using miniscrew anchorage and rocking chair archwire in treatment adult angle Class Ⅱdivision 2 malocclusion. However,in intruding the upper incisors,improving the lip-teeth relationship and shorting the course of treat-ment ,miniscrew anchorage was better than rocking chair archwire.关键词
