Background Modern clinical orthodontics' functional appliances, a well-established modality of treatment, exhibit an amazing diversity of design. Clinical findings show that people have difficulty adjusting to these devices due to their size and unfixed positioning inside the mouth and that patient adaptation may vary based on the type of orthodontic functional appliance employed. Despite the fact that they appear to inflict more pain and soreness than, for example, removable plates, the effects of various orthodontic functional appliances on patients' acclimation have not yet been researched. Aim The current study's goal was to assess how different functional appliances' shapes and designs affected patients' willingness to accept them. Materials and methods About 20 adult volunteers (10 males and 10 females, age 18-32 years) with marked Class II division 1 malocclusion and not familiar with orthodontic appliances were selected as test subjects. Impressions for working casts were taken, and construction bites were prepared for the fabrication of eight functional appliances of various designs for each individual test subject. These appliances had eight design variations. There were three tests: one for speech effects, one for initial acceptance, and one for final acceptance after wearing different scales. Results Overall, the correlation between the quality of speech and pronunciation after wearing the appliance and the type of functional appliance was statistically significant. The quality of speech and pronunciation after wearing the appliance was maximum in frequency range 1 (FR1), while it was minimum in the medium-size activator. The difference was statistically significant (p=0.001). Overall, the correlation between the comfort and acceptability of functional appliances after wearing them and the type of functional appliance was statistically significant. The acceptance of functional appliances after wearing was maximum in FR1, while it was minimum in the medium-size activator. The difference was statistically significant (p=0.001). Overall, the correlation between the type of functional appliance and initial acceptance was significant statistically, with the maximum initial acceptance in medium-sized activators and the minimum initial acceptance in small bionators (p=0.001). Conclusion The study's findings show that patient acceptance of various kinds of functional appliances varies significantly.
背景 现代临床正畸学中的功能性矫治器是一种成熟的治疗方式，其设计呈现出惊人的多样性。临床研究结果表明，由于这些矫治器的尺寸以及在口腔内未固定的位置，人们在适应它们时存在困难，并且患者的适应情况可能因所使用的正畸功能性矫治器类型而异。尽管它们似乎比例如可摘义齿带来更多的疼痛和酸痛，但各种正畸功能性矫治器对患者适应情况的影响尚未得到研究。
目的 本研究的目的是评估不同功能性矫治器的形状和设计如何影响患者接受它们的意愿。
材料和方法 选择约20名患有明显安氏II类1分类错牙合且不熟悉正畸矫治器的成年志愿者（10名男性和10名女性，年龄18 - 32岁）作为测试对象。制取工作模型的印模，并为每个测试对象制作八个不同设计的功能性矫治器准备咬合记录。这些矫治器有八种设计变体。进行了三项测试：一项用于语音效果测试，一项用于初始接受度测试，一项用于佩戴不同时长后的最终接受度测试。
结果 总体而言，佩戴矫治器后语音和发音质量与功能性矫治器类型之间的相关性具有统计学意义。佩戴矫治器后的语音和发音质量在频率范围1（FR1）中最高，而在中型肌激动器中最低。差异具有统计学意义（p = 0.001）。总体而言，佩戴功能性矫治器后的舒适度和可接受性与功能性矫治器类型之间的相关性具有统计学意义。佩戴后功能性矫治器的接受度在FR1中最高，而在中型肌激动器中最低。差异具有统计学意义（p = 0.001）。总体而言，功能性矫治器类型与初始接受度之间的相关性具有统计学意义，中型肌激动器的初始接受度最高，小型生物调节器的初始接受度最低（p = 0.001）。
结论 该研究结果表明患者对各种功能性矫治器的接受程度存在显著差异。
