To compare the level of satisfaction in the use of wraparound Hawley and thermoplastic maxillary retainers.
The study sample included 70 orthodontic patients (24 males and 46 females), who were in the retention stage (mean age = 20.80 years). All patients wore the two types of maxillary retainer for 1 month each, along with a 3×3 fixed mandibular retainer. After the use of each retainer, the patients responded to a questionnaire evaluating the level of satisfaction with their use of the maxillary retainer. Intergroup comparison was performed by independent tests. Chi-square test was used to evaluate preference for the type of retainer by gender.
The thermoplastic retainer was better for swallowing and the wraparound Hawley appliance was better for hygiene and durability. The other factors evaluated (adaptation, speech, comfort, esthetics, satisfaction, and fitting) did not show significant differences between the retainers. There was also no significant difference in preference for the appliances.
Regarding the overall satisfaction and the preference, there was no difference between the wraparound Hawley and thermoplastic retainers. The wraparound Hawley appliance was better in hygiene and resistance than the thermoplastic retainer; and the thermoplastic appliance was better than the wraparound Hawley for swallowing fluids and saliva.
比较使用环绕式 Hawley 保持器和热塑型上颌保持器的满意度水平。
研究样本包括 70 名正畸患者（24 名男性和 46 名女性），他们处于保持阶段（平均年龄=20.80 岁）。所有患者均佩戴两种类型的上颌保持器各 1 个月，同时佩戴 3×3 固定下颌保持器。使用每种保持器后，患者会对评估使用上颌保持器满意度的问卷做出回应。通过独立 t 检验进行组间比较。使用卡方检验评估性别对保持器类型的偏好。
热塑型保持器在吞咽方面更好，而环绕式 Hawley 保持器在卫生和耐用性方面更好。评估的其他因素（适应性、言语、舒适度、美观、满意度和适配性）在保持器之间没有显示出显著差异。对保持器的偏好也没有显著差异。
就整体满意度和偏好而言，环绕式 Hawley 保持器和热塑型保持器之间没有差异。环绕式 Hawley 保持器在卫生和耐抗性方面优于热塑型保持器；而热塑型保持器在吞咽液体和唾液方面优于环绕式 Hawley 保持器。
