The present study aims to assess the efficacy of elastic occlusal splints on mobile posterior teeth in patients with stage III or IV periodontitis during Steps 1 and 2 of periodontal therapy.
Thirty-eight periodontitis patients, each with at least one mobile maxillary posterior tooth (mobility degree II or III), were randomly assigned to either the Splint group (n = 19), which received maxillary elastic occlusal splints, or the Control group (n = 19), without splints treatment. All patients received Steps 1 and 2 of periodontal therapy. Tooth mobility (TM), masticatory efficiency, probing depth (PD), evaluation of subjective comfort and other parameters were assessed at baseline (T0), 2 ~ 4 weeks (T1) and 6 ~ 8 weeks (T2) after the subgingival scaling. Masticatory efficiency was represented by optical density (OD). The subjective comfort score was recorded using a Visual Analogue Scale (VAS).
The value of OD in the Splint group was significantly greater than that in the Control group from T0 to T2 (0.19 ± 0.08 versus 0.09 ± 0.09, p < 0.05) and from T1 to T2 (0.11 ± 0.06 versus 0.02 ± 0.06, p < 0.05). Compared with the Control group, patients in the Splint group experienced significantly greater reduction in TM of mobile posterior teeth throughout each treatment period, as well as a more pronounced decrease in PD from T0 to T2. The score of VAS was 8.34 ± 1.10 at T1 and 8.52 ± 0.91 at T2 with elastic occlusal splints.
The use of elastic occlusal splints as adjuncts during Steps 1 and 2 of periodontal therapy resulted in additional improvement of the masticatory efficiency of periodontitis patients, as well as the reduction of TM and PD of the mobile posterior teeth.

本研究旨在评估在牙周治疗的第1步和第2步中，弹性咬合夹板对III期或IV期牙周炎患者后牙松动的疗效。
38例牙周炎患者，每人至少有一颗上颌后牙松动（松动度为II度或III度），随机分为夹板组（n = 19），接受上颌弹性咬合夹板治疗，和对照组（n = 19），不进行夹板治疗。所有患者均接受牙周治疗的第1步和第2步。在龈下刮治后的基线（T0）、2至4周（T1）和6至8周（T2）评估牙齿松动度（TM）、咀嚼效率、探诊深度（PD）、主观舒适度评估及其他参数。咀嚼效率用光密度（OD）表示。主观舒适度评分采用视觉模拟量表（VAS）记录。
从T0到T2（0.19±0.08对0.09±0.09，p < 0.05）以及从T1到T2（0.11±0.06对0.02±0.06，p < 0.05），夹板组的OD值显著高于对照组。与对照组相比，夹板组患者在整个治疗期间，活动后牙的TM降低更为显著，并且从T0到T2，PD下降更为明显。使用弹性咬合夹板时，T1时VAS评分为8.34±1.10，T2时为8.52±0.91。
在牙周治疗的第1步和第2步中使用弹性咬合夹板作为辅助手段，可额外提高牙周炎患者的咀嚼效率，并降低活动后牙的TM和PD。
