To identify factors associated with patient satisfaction at least 5 years after orthodontic treatment.
A total of 209 orthodontic patients were included in the study. All subjects were treated with upper and lower fixed orthodontic appliances. Dental casts (n = 627) were examined using the Peer Assessment Rating (PAR) Index pretreatment (T1), at the end of treatment (T2) and at a long-term follow-up (mean, 8.5 years; T3). At T3, a Dental Impact on Daily Living questionnaire was used to assess the long-term effects of orthodontic treatment on daily living and satisfaction with the dentition. Multiple regression analyses were used to quantify associations between patient satisfaction and changes produced by the orthodontic treatment (PAR T2-T1), posttreatment stability (PAR T3), age at the start of treatment (T1), treatment duration (T2-T1), gender, and extraction.
Orthodontic treatment produced a significant improvement of 94.2% in the PAR Index (T2-T1), but this change was not associated with the level of satisfaction when the patient was questioned at least 5 years after treatment. Regression analysis showed that satisfaction was significantly associated only with the long-term posttreatment PAR index (r(2) = 0.125, P < .0001). No significant association was observed with the severity of malocclusion at the beginning (PAR-T1) or end of the orthodontic treatment (PAR-T2), age at T1, the amount of time taken during orthodontic treatment, gender, or extraction.
Over the long term, patient satisfaction is slightly associated with the stability of the orthodontic treatment regardless of the initial occlusal condition or the final result of the orthodontic treatment.
确定至少在正畸治疗后 5 年时与患者满意度相关的因素。
本研究共纳入 209 名正畸患者。所有患者均接受上下颌固定正畸矫治器治疗。使用正畸治疗结果评价（Peer Assessment Rating，PAR）指数，对 627 个牙模进行检查，包括治疗前（T1）、治疗结束时（T2）和长期随访时（平均 8.5 年；T3）。在 T3 时，使用口腔健康影响程度量表（Dental Impact on Daily Living，DIDL）评估正畸治疗对日常生活的长期影响和对牙齿的满意度。采用多元回归分析来量化患者满意度与正畸治疗效果（PAR T2-T1）、治疗后稳定性（PAR T3）、治疗开始时年龄（T1）、治疗时间（T2-T1）、性别和拔牙之间的关系。
正畸治疗使 PAR 指数显著改善了 94.2%（T2-T1），但在治疗结束至少 5 年后询问患者时，这种变化与满意度水平无关。回归分析显示，满意度仅与长期治疗后 PAR 指数显著相关（r²=0.125，P<.0001）。与治疗开始时（PAR-T1）或结束时（PAR-T2）的错颌严重程度、治疗开始时的年龄、正畸治疗时间、性别或拔牙均无显著相关性。
从长远来看，患者满意度与正畸治疗的稳定性略有相关，而与初始的咬合状况或正畸治疗的最终结果无关。
