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 p < 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 (p < 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.

“RA.DI.CA。”夹板治疗下颌功能受限：椎间盘前移未复位患者的回顾性研究


该研究旨在评估 RA.DI.CA 的有效性。夹板治疗颞下颌关节盘移位未复位（ADDwoR）和颌功能限制。作者开展了一项回顾性临床研究。共筛选病历2739份。 141 名患有慢性单侧椎间盘移位且未复位且下颌受限的患者接受多功能 RA.DI.CA 治疗。夹板，被录取。在基线（T0）、治疗后（T1）和随访期间（T2）评估颞下颌疼痛、头痛、熟悉疼痛、颈部疼痛和情绪紧张、最大自发张口度和侧向偏移。进行了描述性统计分析。 Wilcoxon 检验评估了治疗前后以及 T1 和 T2 之间症状和功能方面的变化， p < 0.05。 99 名患者 (70%) 声称自己的下颌功能限制已“治愈”，没有残留疼痛症状，31 名患者 (22%) 改善了症状和下颌功能，11 名患者 (8%) 报告与 T0 相比没有变化，没有人病情恶化。就所有分析参数而言，治疗前后的比较具有统计学意义（ p <0.05）。 RA.DI.CA。事实证明，夹板具有很高的性能，可以通过恢复功能性椎间盘-髁关系和愈合关节组织，在中长期内促进功能和症状恢复。
