Comparison of the correction effect of the PASS appliance and the Twin-block functional appliance combined with self-ligating bracket for Angle Class Ⅱ,Division 1 malocclusions
摘要
Abstract
Objective To compare the correction effect of the PASS appliance and the Twin-block functional appliance combined with self-ligating bracket for Angle Class Ⅱ,Division 1 malocclusions.Methods From February 2020 to May 2022,a total of 72 patients with Angle Class Ⅱ,Division 1 malocclusions in our hospital were selected.They were divided into the study group(n=36)and the control group(n=36)by the random number table method.The control group received treatment with Twin-block functional appliance combined with self-ligating bracket,and the study group was treated with the PASS appliance.The clinical efficacy,teeth alignment time,hard tissue cephalometric measurements[Upper Incisor to Sella-Nasion angle(U1-SN),Upper Incisor to Nasion-A point angle(U1-NA),A point-nasion-B point angle(ANB),Sella-Nasion to A point angle(SNA)],soft tissue cephalometric measurements[upper lip to esthetic plane distance(TUL-FP),lower lip H-line distance,lower lip to esthetic plane distance(TLL-FP),nasolabial angle],correction effect and patient satisfaction were compared between the two groups.Results The overall effective rate of the study group was higher than that of the control group(P<0.05).The maxillary and mandibular teeth alignment time in the study group were shorter than those in the control group(P<0.05).The differences of U1-SN,ANB,SNA and SNB before and after treatment were not different between the two groups(P>0.05).The difference of U1-NA before and after treatment in the study group was higher than that in the control group(P<0.05).The differences of lower lip H-line distance,TUL-FP,nasolabial angle and TLL-FP before and after treatment in the study group were higher than those in the control group(P<0.05).The difference of peer assessment rating(PAR)index before and after treatment was higher in the study group than in the control group(P<0.05).The satisfaction of the study group was higher than that of the control group(P<0.05).Conclusions Compared with the Twin-block functional appliance combined with self-ligating bracket,PASS appliance has a definite effect in the treatment of patients with Angle Class Ⅱ,Division 1 malocclusions.It can enhance the correction effect,improve facial profile aesthetics,shorten the maxillary and mandibular teeth alignment time,and achieve higher patient satisfaction.关键词
