牵引钩可隐藏式球形颊面管与方形颊面管的临床性能对比研究
Comparative study on the clinical performance of concealable traction hook spherical buccal tubes versus conven-tional rectangular buccal tubes
摘要
Abstract
Objective This study comprehensively compares the differences between concealable traction hook spherical buccal tubes(concealable spherical tubes)and conventional rectangular buccal tubes in terms of patient com-fort,incidence of buccal mucosal injury,periodontal health indices,and clinical bond failure rate to provide evidence for clinical application.Methods Thirty subjects were enrolled and treated using a split-mouth design,where the two sides of each patient's oral cavity were randomly as-signed to receive either conventional rectangular buccal tubes(group A)or concealable spherical buccal tubes(group B).During treatment,pain scores,ulcer occur-rence,and bond failure of the first molar buccal tubes were recorded.Periodontal indices,including plaque in-dex(PLI),gingival index(GI),and sulcus bleeding in-dex(SBI)of the first molars,were assessed before treatment(T0)and 30 days after tube bonding(T1).Results The pain scores in group A were significantly higher than those in group B(Z=-5.231,P<0.001).Moderate or higher pain was reported by 86.7%of patients in group A,whereas 90.0%of patients in group B reported mild pain only.The inci-dence of ulcers in group A(76.7%)was significantly higher than that in group B(3.3%,Z=-4.508,P<0.001).After treatment,the periodontal indices in both groups increased significantly compared to pre-treatment levels(P<0.05);however,the increases in PLI,GI,and SBI were significantly greater in group A than in group B(P<0.001).The bond failure rate in group A(26.7%)was significantly higher than that in group B(8.3%,P<0.001).Conclusion The clini-cal performance of concealable spherical buccal tubes is significantly superior to that of conventional rectangular buc-cal tubes in improving patient comfort,reducing the incidence of mucosal injury and clinical bond failure,and maintain-ing periodontal health.This design offers patients a more comfortable and healthier orthodontic treatment experience.关键词
