The study aimed at assessing the effectiveness of the RA.DI.CA. splint in the management of temporomandibular joint disc displacement without reduction (ADDwoR) and jaw functional limitation. The authors developed a retrospective clinical study. A total of 2739 medical records were screened. One hundred and forty-one patients with chronic unilateral disc displacement without reduction and jaw limitation, treated with a multifunctional RA.DI.CA. splint, were enrolled. Temporomandibular pain, headache, familiar pain, neck pain, and emotional strain, maximum spontaneous mouth opening, and lateral excursions were evaluated at baseline (T0), after therapy (T1), and during the follow-up (T2). Descriptive statistical analysis was performed. Wilcoxon test assessed changes in symptomatology and functional aspects before and after treatment and between T1 and T2, with < 0.05. Ninety-nine patients (70%) declared themselves "healed" from jaw functional limitation with no residual painful symptoms, 31 (22%) improved their symptoms and jaw function, 11 (8%) reported no changes compared to T0 and no one worsened. As for all parameters analyzed, the comparison between the ones before and after treatment was statistically significant ( < 0.05). The RA.DI.CA. splint proved to be highly performing and promoting functional and symptomatologic recovery, also in the medium and long term, through the restoration of the functional disc-condyle relationship and the healing of joint tissues.
本研究旨在评估 RA.DI.CA. 夹板在管理不可复性颞下颌关节盘移位（ADDwoR）和颌功能受限中的效果。作者开展了一项回顾性临床研究。共筛选了 2739 份病历。共纳入 141 例慢性单侧不可复性盘前移位伴颌功能受限的患者，采用多功能 RA.DI.CA. 夹板治疗。在基线（T0）、治疗后（T1）和随访（T2）时，评估患者的颞下颌疼痛、头痛、熟悉性疼痛、颈部疼痛、情绪紧张、最大自发开口度和侧方运动。采用描述性统计分析。Wilcoxon 检验评估治疗前后和 T1 与 T2 之间症状和功能方面的变化， < 0.05。99 例（70%）患者自述颌功能受限“治愈”，无残留疼痛症状，31 例（22%）患者症状和颌功能改善，11 例（8%）与 T0 相比无变化，无恶化病例。对于所有分析参数，治疗前后的比较均具有统计学意义（ < 0.05）。RA.DI.CA. 夹板通过恢复关节盘-髁突的功能关系和关节组织的愈合，在中远期也表现出良好的性能，促进了功能和症状的恢复。
