ttu项目的目的是确定儿童功能性后牙反牙合是否影响下颌髁突的位置，并评估反牙合矫正对髁突位置的影响。本文报告十位年龄介于四至九岁的功能性后牙反牙合儿童，以上颌骨扩大术来治疗。在治疗前和反牙合矫正后拍摄标准化的经颅颞下颌关节X线片。治疗前的X光片拍摄时，儿童的牙齿处于反牙合关系。治疗后拍摄牙齿正中咬合的X线片。治疗前，反牙合和非反牙合侧的水平和垂直关节间隙测量值存在显著差异。在反牙合矫正后，两侧之间没有显著差异。
The purpose of ttu's project was to determine whether functional posterior crossbites in children influence the position of the mandibular condyle and assess the effect of crossbite correction on condylar position. Ten children from four to nine years of age with functional posterior crossbites were treated by maxillary expansion. Standardized transcranial temporomandibularjoint radiographs were taken prior to treatment and following crossbite correction. Pretreatment radiographs were taken with the child's teeth occluded in the crossbite relationship. Post treatment radiographs were made with the teeth in centric occlusion. Prior to treatment, there were significant differences in the horizontal and vertical joint space measurements between the crossbite and noncrossbite sides. There were no significant differences between the two sides following crossbite correction.
