摘　　要：目的:探究不同安氏错颌类型患者咬合关系、临床表现差异及CBCT特征。方法:选择2021.1至2023.12于北京中医医院顺义医院和首都医科大学附属北京口腔医院诊治的70例安氏错颌患者,根据不同安氏错颌类型将其分为三组。对比三组相关指标。结果:安氏Ⅲ类组二腹肌(左、右侧)、咬肌(左、右侧)、颞肌(左、右侧)、二腹肌不对称指数、咬肌不对称指数及颞肌不对称指数均高于安氏Ⅰ类组、安氏Ⅱ类组,安氏Ⅱ类组上述咬合关系均高于安氏Ⅰ类组(P<0.05)。安氏Ⅲ类组牙列拥挤>3 cm、开颌、双颌前突、上颌前突、反颌、深覆颌、下颌后缩、磨牙近中关系例数均高于安氏Ⅰ类组、安氏Ⅱ类组;安氏Ⅱ类组上述临床症状例数均高于安氏Ⅰ类组(P<0.05),安氏Ⅲ类组和安氏Ⅱ类组磨牙中性关系均低于安氏Ⅰ类组(P<0.05)。安氏Ⅲ类组SNB°、ANB°、U1-L1°、U1-PP°、L1-MP°均高于安氏Ⅰ类组、安氏Ⅱ类组,安氏Ⅱ类组上述CBCT特征均高于安氏Ⅰ类组(P<0.05);三组SNA°比较(P>0.05)。结论:安氏Ⅲ类错颌类型患者二腹肌、咬肌、颞肌、二腹肌不对称指数、咬肌不对称指数、颞肌不对称指数指标值、SNB°、U1-L1°、U1-PP°、L1-MP°较高,ANB°较低,其临床症状包括牙列拥挤>3 cm、开颌、双颌前突、上颌前突、反颌、深覆颌、下颌后缩、磨牙近中关系。Objective:To explore the occlusal relationship,clinical manifestations and CBCT features of patients with different Ambrosia malocclusion types.Methods:From 2021.1 to 2023.12,70 patients diagnosed and treated in Shunyi Hospital of Beijing Hospital of Traditional Chinese Medicine and Beijing Stomatology Hospital Affiliated to Capital Medical University were selected and divided into three groups according to different types of Angelian malocclusion.Compare three groups of relevant indicators.Results:The abdominal muscle(left and right),masseter muscle(left and right),temporal muscle(left and right),abdominal muscle asymmetry index,masseter asymmetry index and temporal muscle asymmetry index in classⅢgroup were higher than those in classⅠand classⅡgroup,and the above occlusal relationships in classⅡgroup were higher than those in classⅠgroup(P<0.05).The number of occlusal crowding>3 cm,open jaw,bimaxillary protrusion,maxillary protrusion,inverse jaw,deep overbite,mandibular retraction and molar mesial relationship in classⅢwere higher than those in classⅠand classⅡ.The number of clinical symptoms in classⅡgroup was higher than that in classⅠgroup(P<0.05),and the molar neutrality in classⅢgroup and classⅡgroup was lower than that in classⅠgroup(P<0.05).SNB°,ANB°,U1-L1°,U1-PP°,and L1-MP°in classⅢgroup were higher than those in classⅠand classⅡgroups,and the CBCT features in classⅡgroup were higher than those in classⅠgroup(P<0.05).SNA°was compared among the three groups(P>0.05).Conclusion:In patients with ClassⅢmalocclusion,the values of SNB°,U1-L1°,U1-PP°and L1-MP°were higher in the abdominal muscles,masseter muscles,temporal muscles,asymmetry index of the digastric muscles,masseter asymmetry index and temporal muscle asymmetry index,while the values of ANB°were lower.The clinical symptoms include dental crowding>3 cm,open jaw,bimaxillary protrusion,maxillary protrusion,invergnathic,deep overbite,mandibular retraction,molar mesial relationship.
