上顎天生無犬齒案例A shy girl who has no upper canine naturally, and her lower teeth were extremely crowding. The orthodontic treatment plan was to extract the lower first premolar and align all teeth. We achieved good smile alignment (using upper first premolar to substitute upper canine), and de-crowded the lower teeth.The lateral profile was improved, and the chin was a little bit more prominent. The shy girl is not shy anymore, she is happy and smiles more! 上顎天生無犬齒案例,以第一小臼齒取代犬齒 下顎拔除第一小臼齒,騰出空間,順勢緩解前牙擁擠 治療前後骨內牙根更整齊,及咬合弧度更好 治療後,側臉弧線更美,鼻高下巴尖,巧笑倩兮!
