The objective is to compare the impact of clear aligner treatment (CAT) versus conventional fixed appliance treatment (FAT) on oral health-related quality of life (OHRQoL) among adults at five-time points: pretreatment (T0), 1 week (T1), 1 month after (T2), and 6 months after (T3) treatment initiation, and in the long-term follow-up (T4).
Search terms were based on Medical Subject Headings (MeSH) and non-MeSH. Potentially eligible studies compared OHRQoL in clear aligner (CA) and fixed appliance (FA) patients. In February 2023, Scopus, Web of Science, Cochrane, and PubMed were searched for published studies. Nine out of 94 shortlisted papers were eligible for a systematic review. Of these nine papers, five studies were considered for a meta-analysis.
At T0, CA and FA patients had similar oral health impact profile (OHIP)-14 questionnaire scores with a standard mean difference (SMD) of 0.105 (confidence interval [CI]: -1.029-1.48). The SMD of the OHRQoL related to T1, T2, and T3 was -3.119 (CI: -0.145, 0.355), -1.527 (CI: -5.597, -0.64), and - 2.331 (CI: -1.906, -1.148). T4 showed no difference between groups (SMD = 0.007, CI: CI: -4.286, -0.376). Regarding the OHIP-14 domains, functional limitations remained consistent in both groups across all time intervals. Psychological discomfort exhibited a notable difference only at T2. Throughout the treatment, CAT showed significantly lower levels of physical, psychological, and social disability, as well as handicap, though these differences did not persist beyond T4. Notably, physical pain was the sole domain that remained elevated in the FAT group up to T4.
During the 1 day of the orthodontic treatment, both the CA and FA groups had comparable OHRQoL statuses. However, as time passed, the CA group notably improved their OHRQoL compared to the FA group. Interestingly, after a year or the completion of treatment, both groups eventually reached similar OHRQoL levels. Nevertheless, it is worth noting that FA patients continued to experience more physical pain even a year later.
目的是比较成人在五个时间点（治疗前（T0）、治疗开始后1周（T1）、1个月后（T2）、6个月后（T3）以及长期随访（T4）），使用透明矫治器治疗（CAT）与传统固定矫治器治疗（FAT）对口腔健康相关生活质量（OHRQoL）的影响。
检索词基于医学主题词表（MeSH）和非MeSH。潜在符合条件的研究比较了透明矫治器（CA）和固定矫治器（FA）患者的OHRQoL。2023年2月，在Scopus、科学网、考克兰图书馆和PubMed上检索已发表的研究。94篇入围论文中有9篇符合系统评价的条件。在这9篇论文中，有5项研究被纳入荟萃分析。
在T0时，CA组和FA组的口腔健康影响概况（OHIP）-14问卷得分相似，标准平均差（SMD）为0.105（置信区间[CI]：-1.029至1.48）。与T1、T2和T3相关的OHRQoL的SMD分别为-3.119（CI：-0.145，0.355）、-1.527（CI：-5.597，-0.64）和-2.331（CI：-1.906，-1.148）。T4时两组之间无差异（SMD = 0.007，CI：CI：-4.286，-0.376）。关于OHIP-14领域，在所有时间间隔内两组的功能限制均保持一致。心理不适仅在T2时表现出显著差异。在整个治疗过程中，CAT组在身体、心理和社会残疾以及障碍方面的水平显著较低，尽管这些差异在T4之后没有持续存在。值得注意的是，直到T4，FAT组中身体疼痛是唯一仍然较高的领域。
在正畸治疗的1天内，CA组和FA组的OHRQoL状况相当。然而，随着时间的推移，与FA组相比，CA组的OHRQoL有显著改善。有趣的是，在一年或治疗完成后，两组最终达到了相似的OHRQoL水平。尽管如此，值得注意的是，即使在一年后，FA患者仍继续经历更多的身体疼痛。
