摘　　要：目的:探讨成人骨性Ⅲ类错牙合畸形患者的舌肌功能运动状况,观察舌功能运动对骨性Ⅲ类错牙合畸形骨性和牙性特征产生的影响。方法:选取2020年1月-2022年6月笔者医院口腔科的骨性Ⅲ类错牙合畸形患者89例,测量最适张口(Comfortable mouth opening,CMO)的切牙间距离、舌尖上抬至切牙乳头(Tongue tip extended to the incisive papilla,TIP)的切牙间距离、舌体吸附至腭部(Lingual-palatal suction,LPS)的切牙间距离,计算舌前部的活动度(Mobility of the anterior one-third of the tongue,TRMR-TIP=TIP/CMO),舌后部的活动度(Mobility of the posterior two-thirds of the tongue,TRMR-LPS=LPS/CMO),将舌活动度分为四级。通过头颅侧位片和模型分析测量骨性和牙性指标。比较各分级间舌功能活动度与骨性Ⅲ类错牙合畸形骨性和牙性特征的关系。结果:舌前后部活动度三级(低于平均水平)、四级(显著低于平均水平)的SNB、L1-MP比一级(显著高于平均水平)、二级(平均水平)大;舌前后部活动度一级、二级的Go-Gn-SN°比三级、四级大;舌后部活动度一级、二级的上颌尖牙间宽度、上颌磨牙间宽度、下颌尖牙间宽度比三级、四级大;舌后部活动度三级、四级的下颌磨牙间宽度比一级、二级大,差异均有统计学意义(P<0.05)。结论:舌活动度越小,下颌前突越严重,下颌骨向后下旋转趋势越小,下前牙越唇倾。随着舌后部活动度减小,下颌磨牙间宽度增大,上颌尖牙和上颌磨牙间宽度、下颌尖牙间宽度减小。Objective To explore the tongue movement of adults with skeletal ClassⅢmalocclusion.To investigate the changes of skeletal and dental characteristics.Methods 89 cases of skeletal ClassⅢpatients were selected from the Department of Stomatology in First Affiliated Hospital of Dali University.A vernier caliper was used to measure the distance between the maxillary and mandibular incisors while the mouth opened as wide as possible without pain or discomfort(CMO),the distance between the maxillary and mandibular incisors while the tongue tip is extended to the incisal papilla(TIP),and the distance between the maxillary and mandibular incisors while the tongue body is held against the palate in lingual-palatal suction(LPS).The distance of TIP divided by CMO was defined as TRMR-TIP,which assess the mobility of the anterior one-third of the tongue.The distance of LPS divided by CMO was defined as TRMR-LPS,which assess the mobility of the posterior twothirds of the tongue.Patients were classified into 4 levels groups according to their tongue mobility.Cephalometrics and models were taken.The skeletal and dental characteristics among the four groups were compared,and the correlation between tongue mobility and skeletal ClassⅢwas analyzed.Results The SNB,L1-MPof level 3 and 4 were greater than those of level 1 and 2.The Go-Gn-SN,mandibular intercanine width of level 1and 2 were greater than those of level 3 and 4.The mandibular intercanine width of level 1and 2 were greater than those of level 3 and 4.TRMR-LPS team’s maxillary intercanine,intermolar and mandibular intercanine width of level 1 and 2 were greater than level 3and 4.TRMR-LPS team's mandibular intermolar width of level 3 and 4 were greater than level 1 and 2.There were significant statistical differences(P<0.05).Conclusion As the range of tongue movement decreases,the more serious mandibular protrsuion,the less trend of mandibular clockwise rotation,lower anterior incisors flarer.The lower of posterior tongue motion,the mandibular intermolar width are la
