摘　　要：目的比较双[牙合]垫矫治器与隐形功能矫治器治疗恒牙列早期骨性Ⅱ类错[牙合]畸形的效果。方法回顾性分析2020年1月至2021年12月萍乡市人民医院收治的80例恒牙列早期骨性Ⅱ类错[牙合]患者,根据佩戴矫治器的不同分为双[牙合]垫组(n=42)和隐形功能组(n=38)。双[牙合]垫组患者使用双[牙合]垫矫治器治疗,隐形功能组患者使用全透明隐形材料下颌功能矫治器治疗,两组患者均治疗1年,比较两组治疗前后的治疗有效率、前牙覆盖(OJ)、前牙覆[牙合](OB),比较两组治疗前后牙性[上中切牙的突度(U1-NA距)、上中切牙的倾斜度(U1-NA角)、下中切牙的突度(L1-NB距)]、骨性[鼻根点到上齿槽点连线与前颅底平面夹角(SNA角)、鼻根点到下齿槽点连线与前颅底平面夹角(SNB角)、SNA角和SNB角的差值(ANB角)],并比较两组的矫正过程满意度。结果两组治疗后的治疗有效率比较,差异无统计学意义(P>0.05);两组患者治疗后的OJ、OB、U1-NA角、U1-NA距、L1-NB距、SNA角、SNB角、ANB角比较,差异无统计学意义(P>0.05);隐形功能组治疗后的矫正满意度高于双[牙合]垫组,差异有统计学意义(P<0.05)。结论在以下颌后缩为主要临床表现的恒牙列早期骨性Ⅱ类错[牙合]患者治疗中,隐形功能矫治器和双[牙合]垫矫治器的临床疗效相当,对患者的牙列、牙性、骨性指标均有明显改善,且隐形功能矫治器患者临床治疗过程满意度更高。Objective To compare the effect of twin-block appliance and invisible functional appliance in the treatment of early skeletal classⅡmalocclusion of permanent teeth.Methods A total of 80 patients with skeletal classⅡmalocclusion in early permanent teeth admitted to the Pingxiang People's Hospital from January 2020 to December 2021 were retrospectively analyzed.According to the different appliance wearing,they were divided into twin-block group(n=42)and invisible functional group(n=38).Patients in the twin-block group were treated with twin-block appliance,and patients in the invisible functional group were treated with fully transparent and invisible mandibular appliance.Both groups were treated for 1 year.The treatment efficiency,anterior overjet(OJ)and anterior overbite(OB)were compared between the two groups before and after treatment.The dental(upper central incisor protrusion[U1-NA distance],upper central incisor inclination[U1-NA angle],lower central incisor protrusion[L1-NB distance]),bony(the angle between the nasion point to the upper alveolar point and the plane of the anterior skull base[SNA angle],the angle between the nasion point to the line of the inferior alveolar point and the plane of the anterior skull base[SNB angle],and the difference between SNA angle and SNB angle[ANB angle])between the two groups before and after treatment were compared.And the satisfaction of the correction process were compared between the two groups.Results There was no statistically significant difference in the effective rate between the two groups after treatment(P>0.05).There were no statistically significant differences in OJ,OB,U1-NA angle,U1-NA distance,L1-NB distance,SNA angle,SNB angle and ANB angle between the two groups after treatment(P>0.05).The correction satisfaction of the invisible functional group was higher than that of the twin-block group after treatment,and the difference was statistically significant(P<0.05).Conclusion In the treatment of skeletal classⅡpatients with mandibular retrusion in e
