摘　　要：对7例安氏Ⅱ类1分类错患者进行 FR-1型矫治器治疗。患者平均年龄11.6岁。下颌前伸3～5mm,(牙合)打开距离平均3.1mm。平均疗程8月。采用东芝的 LGM-2型多轨迹断层摄影,观察治疗前后髁突位置的变化。发现矫治前后髁突处于同一位置,其机理主要为髁突向后上生长所致。To treat Class Ⅱ division 1 malocclusion with Fr(?)nkel appliance(FR-1)in 7 patien-ts.The patients ranged in age from 9.3 to 14 years old,average 11.6-year-old.TheFr(?)nkel appliance was constructed wax bite on 3-5mm protrusive position.The biteopening at molars was mean 3.1mm.Standardized laminographs were taken with and without the fr(?)nkel appliance inpre-and post-treatment to observe the condylar positional changes in fossa.The resultsshowed that the condylar position has no significant difference between pre-and post-tr-eatment.The mechanism was attributed to condylar growth upward and backward.
