摘　　要：目的探讨Twin-Block双期矫治与单纯直丝弓矫正技术在替牙及恒牙早期错(牙合)畸形矫正患儿中的疗效对比。方法选取我院2020年9月到2023年9月收治的60例恒牙早期错(牙合)畸形患儿作为研究对象,按照治疗方法不同分为观察组与对照组,各组均为30例。所有患儿均采取矫正治疗,对照组患儿采取直丝弓矫正技术进行治疗,观察组患儿采取Twin-Block矫治器及直丝弓矫治技术进行双期治疗。对比两组患儿临床疗效,及矫治时间,治疗前头影测量及关节改建情况,采用口腔锥形束扫描成像进行检测两组患儿关节窝宽径、关节前间隙、关节后间隙、关节上间隙、髁突前后径、髁突高度相关参数表达水平,最后对比两组患儿治疗前后上下齿槽座(ANB)角、下齿槽座(SNB)角、上齿槽座(SNA)角、下颌平面角(Mp-SN)、下颌综合长度(Ar-Po)、下颌升支高度(Ar-Go)、下颌体长(Go-Gn)、上中切牙-SN平面角(U1-SN)、下中切牙-下颌平面角(L1-Mp)、上唇审美平面距(Ls-E)、下唇审美平面距(Li-E)、鼻唇角。结果观察组治疗总有效率96.67%明显高于对照组76.67%(P<0.05);治疗后,观察组矫治时间长于对照组(P<0.05);治疗前,两组患儿关节窝宽径、关节前间隙、关节后间隙、关节上间隙、髁突前后径、髁突高度对比无明显差异(P>0.05),治疗后,两组患儿关节窝宽径对比无明显差异,关节前间隙减小,观察组(1.21±0.28)mm高于对照组,关节后间隙、关节上间隙、髁突前后径、髁突高度均增加,且观察组高于对照组(P<0.05);治疗前,两组患儿ANB角、SNB角、SNA角、Mp-SN、Ar-Po、Ar-Go、Go-Gn、U1-SN、L1-Mp、Ls-E、Li-E、鼻唇角对比无明显差异(P>0.05),治疗后,两组患儿SNB、Mp-SN、Ar-Po、Ar-Go、Go-Gn、鼻唇角均增大,ANB、U1-SN、L1-Mp、Li-E、Ls-E减小,且观察组变化大于对照组(P<0.05)。结论Twin-Block矫治器配合直丝弓矫治技术双期矫治器与单纯直丝弓矫正技�Objective To compare the efficacy and periodontal aesthetic effects of Twin Block appliance and straight wire arch correction technology in correcting malocclusion in children during mixed dentition period.Method:Sixty children with early permanent tooth malocclusion admitted to our hospital from September 2020 to September 2023 were selected as the research objects,and were divided into observation group and control group according to different treatment methods,with 30 cases in each group.All the children were treated with correction,the control group was treated with straight wire arch correction technology,and the observation group received Twin-Block appliance and straight wire arch correction technology for double-stage treatment.The observation group received two-stage treatment using Twin Block appliances and straight wire arch correction technology.Compare the clinical efficacy,aesthetic score,correction time,cephalometric measurement and joint remodeling before treatment between the two groups of children.Use oral cone beam scanning imaging to detect the expression levels of parameters related to the width of the joint fossa,anterior and posterior joint spaces,supraarticular spaces,anterior and posterior condylar diameter,and condylar height of the two groups of children.Finally,compare the angles of the upper and lower alveolar base(ANB)and lower alveolar base(SNB)before and after treatment between the two groups of children Upper teeth socket angle(SNA),mandibular plane angle(Mp-SN),mandibular comprehensive length(Ar Po),mandibular ramus height(Ar Go),mandibular body length(Go Gn),upper central incisor SN plane angle(U1-SN),lower central incisor mandibular plane angle(L1-Mp),upper lip aesthetic plane distance(Ls-E),lower lip aesthetic plane distance(Li-E),nasolabial angle.Result:The total effective rate of 96.67%in the observation group was significantly higher than 76.67%in the control group(P<0.05);After treatment,the correction time in the observation group was longer than that in the control group
