项目摘要

Temporomandibular joint (TMJ) clicking is the commonest sign of mandibular dysfunction and is considered by some to be pathologic or potentially harmful. Correction of occlusal problems is sometimes considered important in helping to re-establish a proper condyle-disc relationship and orthodontic therapy is sometimes recommended. Conversely TMJ clicking may arise during or after orthodontic therapy possibly due to occlusal changes or the effects of mechanics of the TMJ. TMJ clicking in approximately 50 pre-orthodontic patients will be recorded on paper tape for in depth analysis of the character of the sound. Simultaneous videotape recording of jaw movements will permit analysis of the timing of the sound. The static occlusion will be analysed on study models and the functional occlusion will be assessed clinically. Another group of 50 pre-orthodontic patients without clicking will be evaluated longitudinally in a similar way. The data wil be recorded prior to, after 6 months and 12 months of treatment in both the clicking and non-clicking groups. A cross-sectional study on approximately 30 patients with clicking and 30 without clicking will be done at the end of active orthodontic treatment and two years post-treatment to complement the longitudinal pilot study. Associations between various malocclusion characteristics and orthodontic mechanotherapy, with the presence, onset or resolution of various types of TMJ sounds will be explored using appropriate statistical analyses.

颞下颌关节（TMJ）喀喇音是下颌骨最常见的症状，一些人认为是病理性的或潜在的有害咬合问题的矫正有时被认为是重要的帮助重建正确的髁突-椎间盘关系，有时推荐正畸治疗。相反地，颞下颌关节敲击可能可能由于咬合变化而在正畸治疗期间或之后出现或者是颞下颌关节的力学效应。颞下颌关节在大约50 矫正前的病人将被记录在纸带上，分析声音的特征。同步录像将允许分析声音的时间。的将在研究模型上分析静态咬合，将对闭塞进行临床评估。另一组50名正畸前没有喀喇音的患者将在类似的路上了数据将在植入前、植入后6个月和植入后12个月进行记录。在点击和非点击组中的治疗。的截面对约30名有喀喇音和30名无喀喇音患者的研究将在积极的正畸治疗结束时和两年后处理，以补充纵向试点研究。协会各种错牙合特征与正畸机械疗法，与存在，发病或解决各种类型的将使用适当的统计分析探索TMJ声音。
