A questionnaire sent to all U.K. hospital orthodontic consultants resulted in an 88 per cent response rate. The average waiting time for initial consultation was 31.6 weeks for routine cases and 3.6 weeks for urgent cases. The average waiting time for out patient treatment was 68.7 weeks for routine cases and 7.5 weeks for urgent cases. Nearly 33 per cent of hospitals used the Dental Health Component of the Index of Orthodontic Treatment need (IOTN) as a guide to placing patients on waiting lists. 'Urgency' and 'Complexity' were used more frequently than indices. Sixty-nine per cent of hospitals exclude some categories of malocclusion from treatment in their departments. A prospective survey reported on 2480 completed treatments over a six week period and there was an average discontinuation rate of 9.2 per cent of all cases finished during the period. Comparison of the completed and discontinued groups revealed few significant treatment-related factors. There was some evidence that the more senior and experienced the operator, the less the rate of discontinuation. A greater rate of discontinuation was seen in removable appliance cases when compared with fixed appliance cases.
向英国所有医院的正畸顾问发放了一份调查问卷，回收率为88%。常规病例初次咨询的平均等待时间为31.6周，紧急病例为3.6周。常规病例门诊治疗的平均等待时间为68.7周，紧急病例为7.5周。近33%的医院将正畸治疗需求指数（IOTN）中的牙齿健康成分作为将患者列入等候名单的指导。“紧急程度”和“复杂程度”比指数更常被使用。69%的医院在其科室治疗中排除了某些错牙合类别。一项前瞻性调查报道了六周内2480例完成的治疗，在此期间完成的所有病例的平均中断率为9.2%。对完成治疗组和中断治疗组的比较显示，几乎没有与治疗相关的显著因素。有证据表明，操作人员越资深、经验越丰富，中断率越低。与固定矫治器病例相比，活动矫治器病例的中断率更高。
