To assess the current professional concept of orthodontic treatment complexity.
Cross sectional survey of practitioners' views towards recently completed orthodontic treatments.
Specialist and non-specialist practitioners in General Dental Services in North Western and Mersey regions. The sampling was carried out between 1993-95.
All practitioners undertaking orthodontic treatments in the GDS in the North Western and Mersey regions were invited to participate. Practitioners submitted consecutively started cases for scrutiny by analysis of study models and pre-treatment and post-treatment questionnaires. 280 cases were collected. Data were analysed using multiple linear regression.
The occlusal changes were assessed using the Index of Orthodontic Treatment Need and the Peer Assessment Rating. Self administered questionnaires employed 5-point Likert type scales to record practitioners' and patients' opinions.
It appears that the concept of complexity is related to the occlusal changes which occur during orthodontic treatment. Attempts to define treatment complexity identifies factors which are of questionable validity and could be easily manipulated in practice setting.
The present concepts of treatment complexity appear to be somewhat flawed. There is no occlusal index of complexity which is particularly satisfactory but as a crude interim measure 3 grades of complexity are proposed based on the PAR index.
评估当前正畸治疗复杂性的专业概念。
对从业者对近期完成的正畸治疗的看法进行横断面调查。
西北和默西地区普通牙科服务中的专科和非专科从业者。抽样于1993 - 1995年间进行。
邀请西北和默西地区普通牙科服务中所有进行正畸治疗的从业者参与。从业者提交连续开展的病例，通过研究模型分析以及治疗前和治疗后问卷进行审查。共收集了280个病例。数据采用多元线性回归分析。
使用正畸治疗需求指数和同行评估评分来评估咬合变化。自行填写的问卷采用5点李克特量表记录从业者和患者的意见。
复杂性的概念似乎与正畸治疗期间发生的咬合变化有关。试图定义治疗复杂性时所确定的因素有效性存疑，且在实际操作中可能易于操控。
目前的治疗复杂性概念似乎存在一定缺陷。没有一个特别令人满意的复杂性咬合指数，但作为一个粗略的临时措施，基于PAR指数提出了3个复杂性等级。
