To evaluate patients' and parents' reactions to the orthodontic treatment of open bite patients with a mandibular lingual arch and spurs (MASP) and to compare any changes in anxiety and discomfort during treatment in different age groups and sexes.
Seventy-two patients completed a baseline questionnaire to assess their levels of discomfort and reaction to this appliance. The patients were divided into two groups: Group 1 consisted of 33 patients up to 14 years of age, and group 2 comprised 39 patients 15 years of age and older. A random group of 72 parents composed a special group. Parents' reactions were assessed through analysis of data gathered from an additional questionnaire with specific questions on their children's reactions.
Ninety-eight percent of the patients accepted treatment with an MASP. The discomfort time was up to 10 days in the majority of patients. The younger group and the female group seemed to show higher tolerance to an MASP. Speech and chewing impairments were the most common functional problems associated with an MASP. Seventy-six percent of subjects did not feel a lack of confidence when wearing an MASP.
This treatment was well accepted by patients and parents. This positive result seems to be closely related to how informed they were. Speech and chewing impairments, the most common functional problems, were temporary.
评估下颌舌弓及支抗（MASP）治疗开牙合患者时患者及家长的反应，并比较不同年龄组和性别的患者在治疗期间焦虑和不适的变化。
72例患者完成了一份基线问卷，以评估他们对该矫治器的不适程度和反应。患者分为两组：第1组由33例14岁及以下的患者组成，第2组由39例15岁及以上的患者组成。随机选取的72名家长组成一个特殊组。通过分析从一份关于其子女反应的附加问卷收集的数据来评估家长的反应。
98%的患者接受了MASP治疗。大多数患者的不适时间长达10天。较年轻组和女性组似乎对MASP表现出更高的耐受性。言语和咀嚼障碍是与MASP相关的最常见功能问题。76%的受试者佩戴MASP时没有感到缺乏自信。
这种治疗方法得到了患者和家长的良好接受。这一积极结果似乎与他们了解的程度密切相关。言语和咀嚼障碍这两个最常见的功能问题是暂时的。
