The evidence supporting the use of stabilisation splints in the treatment of temporomandibular disorders (TMD) is scarce and a need for well-controlled studies exists. The aim of this randomised, controlled trial study was to assess the efficacy of stabilisation splint treatment on TMD. The sample consisted of 80 consecutive referred patients who were randomly assigned to the splint group (n = 39) and the control group (n = 41). Subjects in the splint group were treated with a stabilisation splint, whereas subjects in the control group did not receive any treatment except counselling and instructions for masticatory muscle exercises which were given also to the subjects in the splint group. Outcomes were visual analogue scale (VAS) on facial pain intensity and clinical findings for TMD which were measured at baseline and after 1-month follow-up. The differences in change between the groups were analysed using regression models. Facial pain decreased and most of the clinical TMD findings resolved in both of the groups. The differences in changes in VAS or clinical TMD findings between the groups were not statistically significant. The findings of this study did not show that stabilisation splint treatment in combination with counselling and masticatory muscle exercises has additional benefit in relieving facial pain and increasing the mobility of the mandible than counselling and masticatory muscle exercises alone in a short time-interval.
支持在颞下颌关节紊乱病（TMD）治疗中使用稳定夹板的证据很少，需要进行良好对照的研究。本随机对照试验的目的是评估稳定夹板治疗 TMD 的疗效。该样本由 80 名连续就诊的患者组成，他们被随机分配到夹板组（n = 39）和对照组（n = 41）。夹板组的患者接受稳定夹板治疗，而对照组的患者除了接受咨询和咀嚼肌运动指导外，没有接受任何治疗，这些指导也提供给了夹板组的患者。在基线和 1 个月随访时，通过视觉模拟评分（VAS）评估面部疼痛强度和 TMD 的临床发现。使用回归模型分析组间变化的差异。两组的面部疼痛均减轻，大多数 TMD 临床发现均得到缓解。两组间 VAS 或 TMD 临床发现的变化差异无统计学意义。本研究的结果表明，在短期内，稳定夹板治疗联合咨询和咀嚼肌运动与单纯咨询和咀嚼肌运动相比，在缓解面部疼痛和增加下颌活动度方面没有额外的益处。
