The aims of the study were to relate patient satisfaction and perceived psychosocial benefit to professional assessed treatment and long-term outcome. Questionnaires were mailed to 250 patients treated previously in a postgraduate clinic. The response rate was 79%, and the mean age was 28.3 years. Professionally defined outcome was assessed according to the Index of Orthodontic Treatment Need (IOTN) and the Peer Assessment Rating (PAR) index applied to dental casts at the start of treatment (T1), at the end of active treatment (T2) and 5 to 10 years out of retention (T3). Data from 177 cases were used in comparison analysis between patients' and orthodontists' assessments. There was high patient satisfaction with dental appearance (87.0%) and treatment results (77.4%). The aesthetic component of IOTN at T2, PAR score at T3, extraction/non-extraction, pre-treatment concern for dental appearance, sex and treatment time accounted for 33% (R2 = 0.33) of the variability of satisfaction with own dental appearance. Explanatories for self-perceived psychosocial benefit of treatment were pre-treatment concern for dental appearance, aesthetic component at T1 and T3 and PAR score at T3, (R2 = 0.22). Stepwise logistic regression analysis selected change in upper anterior segment (T3-T2) as the most important component of PAR index features for grouping satisfied and dissatisfied individuals (Odds ratio = 0.65) together with satisfaction with own dental appearance (Odds ratio = 7.28). The results indicate some discrepancies between professionally assessed outcome and patient satisfaction and perceived psychosocial benefit. The aesthetic component was a stronger indicator for patient satisfaction and perceived benefit than the PAR index.
本研究的目的是将患者满意度和感知到的心理社会效益与专业评估的治疗及长期结果联系起来。向250名曾在研究生诊所接受治疗的患者邮寄了问卷。回复率为79%，平均年龄为28.3岁。根据正畸治疗需求指数（IOTN）和用于治疗开始时（T1）、积极治疗结束时（T2）以及保持期结束5至10年后（T3）牙模的同伴评估评分（PAR）指数对专业定义的结果进行评估。177例患者的数据用于患者与正畸医生评估之间的比较分析。患者对牙齿外观（87.0%）和治疗结果（77.4%）的满意度较高。T2时IOTN的美学成分、T3时的PAR评分、拔牙/不拔牙、治疗前对牙齿外观的关注、性别和治疗时间占对自身牙齿外观满意度变异性的33%（R2 = 0.33）。治疗自我感知心理社会效益的解释因素为治疗前对牙齿外观的关注、T1和T3时的美学成分以及T3时的PAR评分（R2 = 0.22）。逐步逻辑回归分析选择上前牙段的变化（T3 - T2）作为PAR指数特征中对满意和不满意个体进行分组的最重要成分（优势比 = 0.65），同时还有对自身牙齿外观的满意度（优势比 = 7.28）。结果表明，专业评估的结果与患者满意度及感知到的心理社会效益之间存在一些差异。美学成分比PAR指数更能有力地表明患者满意度和感知到的益处。
