Analysis of Occlusal Relationship,Clinical Manifestations and CBCT Features in Patients with Different Ambrosia Malocclusion Types
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 class Ⅲ group were higher than those in class Ⅰ and classⅡ group,and the above occlusal relationships in class Ⅱ group were higher than those in class Ⅰ group(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 class Ⅲ were higher than those in class Ⅰ and class Ⅱ.The number of clinical symptoms in class Ⅱgroup was higher than that in class Ⅰ group(P＜0.05),and the molar neutrality in class Ⅲ group and class Ⅱ group was lower than that in class Ⅰ group(P＜0.05).SNB°,ANB°,U1-L1°,U1-PP°,and Ll-MP° in class Ⅲ group were higher than those in classⅠ and class Ⅱ groups,and the CBCT features in class Ⅱ group were higher than those in class Ⅰ group(P＜0.05).SNA° was compared among the three groups(P＞0.05).Conclusion:In patients with Class Ⅲ malocclusion,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.
