The purpose of this descriptive study was to estimate retainer wear and compliance among orthodontic patients in the first 2 years after active orthodontic treatment.
A random sample of 1200 orthodontic patients was selected from 4 offices. Data were collected by a self-administered questionnaire that consisted of 6 items: type of retainer prescribed, age, sex, length of time since debond, and hours per day and nights per week that patients wore their retainers. Responses were solicited by mail or the Internet. Data were gathered on a categorical scale and analyzed.
The overall response rate was 36% during a 6-week period. In the first 3 months after debond, 60% of patients were wearing their retainers more than 10 hours during a 24-hour cycle, and 69% were wearing the retainers every night. At 19 to 24 months after debond, 19% of the patients were not wearing their retainers, and 81% wore their retainers at least 1 night per week. Compliance rates during the periods of 0 to 3, 4 to 6, 7 to 9, 10 to 12, 13 to 18, and 19 to 24 months were 69%, 76%, 55%, 62%, 45%, and 45%, respectively. Age, sex, and type of retainer did not influence the levels of compliance.
Most continued to wear their retainers at least 1 night per week, with compliance rates, as defined, tending to decrease in our sample. It was encouraging that 81% of the patients in this sample largely maintained their orthodontic result.
本描述性研究的目的是估算正畸治疗结束后 2 年内保持器的佩戴率和患者的遵嘱情况。
从 4 家诊所中抽取了 1200 名正畸患者的随机样本。通过一份包含 6 个项目的自我管理调查问卷收集数据：规定使用的保持器类型、年龄、性别、从粘结拆除到研究时的时间、每天佩戴保持器的小时数以及每周佩戴保持器的夜数。通过邮寄或互联网收集数据。数据采用分类尺度进行分析。
在 6 周的时间内，总的回复率为 36%。粘结拆除后的前 3 个月，60%的患者在 24 小时周期内佩戴保持器的时间超过 10 小时，69%的患者每天晚上都佩戴保持器。粘结拆除后 19 至 24 个月，19%的患者不佩戴保持器，81%的患者每周至少佩戴保持器 1 晚。粘结拆除后 0 至 3 个月、4 至 6 个月、7 至 9 个月、10 至 12 个月、13 至 18 个月和 19 至 24 个月期间的遵嘱率分别为 69%、76%、55%、62%、45%和 45%。年龄、性别和保持器类型并未影响遵嘱水平。
大多数患者至少每周晚上还佩戴保持器，我们的样本中，遵嘱率呈下降趋势。令人鼓舞的是，我们的样本中有 81%的患者在很大程度上保持了正畸治疗的效果。
