This cross-sectional study aimed to explore the level of knowledge and expectations people deciding on a future orthodontic treatment have about post-orthodontic retention and to investigate the influence of sociocultural characteristics.
A total of 227 consecutive people involved as legal decision maker (as patient, parent, or legal guardian) for a prospective orthodontic treatment (mean age 37.1 years; 37.3 per cent male) received before their first appointment a questionnaire to assess their knowledge and expectations about post-orthodontic retention. Data were analysed descriptively, whereas predictors were identified with logistic regressions at P value of less than or equal to 0.05.
Among the 220 responders, 46.3 per cent (n = 99) knew that retention appliances are used after orthodontic treatment and 52.8 per cent (n = 113) believed perfect results can guarantee stability, whereas at the same time, 77.8 per cent (n = 168) knew that teeth can move on their own without any orthodontic appliances. The majority considered stability of the orthodontic result important or extremely important (94.5 per cent; n = 206), preferred bonded over removable retainers (67.2 per cent; n = 133), believed the orthodontist to be primarily responsible for a stable result (73.2 per cent; n = 158), and found it appropriate to charge for recall visits (72.9 per cent; n = 153). Participants' gender, age, education, nationality, and past orthodontic experiences within the close family significantly influenced answers.
The setting of a single-centred survey conducted in one university moderates the generalizability of the portrayed results.
Although stability of orthodontic treatment results is very important to people deciding about a prospective orthodontic treatment, knowledge regarding the need for post-orthodontic retention varies and may at times be contradictious. Sociocultural factors seem to influence the level of knowledge and the expectations on post-orthodontic retention.
本横断面研究旨在探讨决定未来正畸治疗的人群对正畸后保持的知识水平和期望，并调查社会文化特征的影响。
共纳入 227 名作为前瞻性正畸治疗的法定决策者（患者、家长或法定监护人）（平均年龄 37.1 岁；37.3%为男性），在首次就诊前接受问卷调查，以评估他们对正畸后保持的知识和期望。数据进行描述性分析，采用逻辑回归识别有统计学意义的预测因子（P 值小于或等于 0.05）。
在 220 名应答者中，46.3%（n=99）知道正畸治疗后使用保持器，52.8%（n=113）认为完美的结果可以保证稳定性，而同时 77.8%（n=168）知道牙齿在没有任何正畸器械的情况下也可以自行移动。大多数人认为正畸结果的稳定性很重要或极其重要（94.5%；n=206），更喜欢黏结式保持器而不是可摘式保持器（67.2%；n=133），认为正畸医生对稳定的结果负有主要责任（73.2%；n=158），并认为收取复诊费用是合理的（72.9%；n=153）。参与者的性别、年龄、教育程度、国籍以及在近亲中接受过的正畸经历显著影响了他们的回答。
单中心调查的设置以及在一所大学进行调查限制了所呈现结果的普遍性。
尽管决定进行前瞻性正畸治疗的人群非常重视正畸治疗结果的稳定性，但他们对正畸后保持的必要性的知识各不相同，有时甚至相互矛盾。社会文化因素似乎影响了人们对正畸后保持的知识水平和期望。
