BACKGROUND/AIM: Luxation is a common traumatic dental injury treated with a wire composite (WC) splint. However, bulk-fill flowable composite and conventional packable composite have not been compared for retaining these splints. Therefore, the objectives of this randomized controlled trial were (1) to compare retention of WC splints, and (2) to compare adhesive point dimension, application and removal time, and effect on tooth mobility between the two WC splints.
In this parallel group, non-inferiority double blind randomized controlled trial, a total of 90 patients, aged 16-50 years participated. They were randomly allocated into two groups, the packable composite group (PC) n = 45 and the bulk-fill flowable composite group (BF-FC) n = 45 by lottery method. Following measurements were taken at the splint application appointment. Horizontal tooth mobility measured via Periotest, splint application time, and frontal images of splinted teeth to measure the percentage composite adhesive point area. After 2 weeks, splints were visually inspected for retention, whereas mobility and removal times were also recorded. Statistically, comparisons were made using independent samples sample T-test, Fisher's exact test, and Mann-Whitney U at p ≤ .05.
A total of 88 patients with 156 luxated teeth completed the trial, as two patients were lost to follow-up. Two patients in the PC group reported with completely de-bonded splints while none de-bonded in the BF-FC group. Both groups were similar in terms of splint retention (p = .352), reduction of mobility (p = .426), and splint removal times (p = .372). The BF-FC group performed significantly better in adhesive point dimension percentages (p < .001) and splint application time (p < .001).
Both groups were comparable in most parameters of the study. However, for BF-FC group application time and adhesive point dimension were significantly less.
背景/目的：脱位是一种常见的外伤性牙损伤，采用钢丝复合（WC）夹板治疗。然而，尚未比较过用于保留这些夹板的块状填充可流动复合材料和传统可填充复合材料。因此，本随机对照试验的目的是：（1）比较 WC 夹板的保留情况，以及（2）比较两种 WC 夹板的粘合点尺寸、应用和去除时间以及对牙齿活动性的影响。
在这项平行组、非劣效性双盲随机对照试验中，共有 90 名年龄在 16-50 岁的患者参与。他们通过抽签法被随机分为两组，可填充复合材料组（PC）n=45 例和块状填充可流动复合材料组（BF-FC）n=45 例。在夹板应用预约时进行以下测量。使用 Periotest 测量水平牙齿活动性，记录夹板应用时间和夹板牙齿的正面图像以测量复合粘合点面积的百分比。2 周后，对夹板的保留情况进行视觉检查，同时记录活动性和去除时间。统计分析采用独立样本 t 检验、Fisher 确切检验和 Mann-Whitney U 检验，p 值≤0.05。
共有 88 名患者的 156 颗脱位牙完成了试验，有 2 名患者失访。PC 组有 2 名患者报告夹板完全脱胶，而 BF-FC 组则没有。两组在夹板保留情况（p=0.352）、活动性降低（p=0.426）和夹板去除时间（p=0.372）方面相似。BF-FC 组在粘合点尺寸百分比（p<0.001）和夹板应用时间（p<0.001）方面表现明显更好。
两组在研究的大多数参数方面相似。然而，BF-FC 组的应用时间和粘合点尺寸明显更小。
