A retrospective questionnaire survey of 111 retention-period adult patients was performed to examine discomfort that may be caused by bonded lingual orthodontic appliances. Despite instructions to avoid or relieve the discomfort, 57% to 76% of patients complained of tongue soreness, difficulty in chewing fibrous food, difficulty in pronouncing the s and t sounds, and difficulty in tooth brushing after the bonding of lingual appliances; the levels were significantly higher than those undergoing edgewise labial treatment. Twenty percent to 44% of patients experienced high levels of the aforementioned discomfort. Although this discomfort decreased gradually with time, 20% to 46% of patients felt discomfort until after the removal of the lingual appliances. The ratio of tongue soreness and speech difficulty caused by upper lingual bracket application to lower lingual bracket application was almost equal. Rank correlation analyses revealed two things: the deeper the bite, the greater the level of tongue soreness, teeth pain and difficulty in chewing tough food; and the larger the overjet, the greater the level of tongue soreness.
对111名处于矫治保持期的成年患者进行了回顾性问卷调查，以调查舌侧固定正畸矫治器可能引起的不适。尽管已告知患者避免或缓解不适，但57%至76%的患者在舌侧矫治器粘结后抱怨有舌部酸痛、咀嚼纤维性食物困难、发/s/和/t/音困难以及刷牙困难；这些情况的发生率显著高于接受唇侧方丝弓矫治的患者。20%至44%的患者经历了上述高水平的不适。尽管这种不适会随着时间逐渐减轻，但20%至46%的患者在舌侧矫治器拆除后仍感到不适。上舌侧托槽应用引起的舌部酸痛和言语困难与下舌侧托槽应用的比例几乎相等。等级相关分析揭示了两点：覆合越深，舌部酸痛、牙齿疼痛和咀嚼硬质食物困难的程度越高；覆盖越大，舌部酸痛的程度越高。
