Abstract

Aim: The aim of this study was to compare the improvement of pain between a digitally constructed stabilization splint (SS) and anterior repositioning splint (ARS) for patients with anterior disc displacement with reduction (DDWR).

Settings and design: The trial was a cross-over randomized control trial.

Materials and methods: Twenty patients were diagnosed using magnetic resonance imaging to have anterior disc displacement were included in the following trial. All included patients met the inclusion criteria and they were all suffering from pain and were classified as anterior DDWR. They were randomized using the sealed envelopes into two groups. Group A patients received ARS for 3 months and then SS for another 3 months after a 14-day wash out period, while in group B patients received SS for 3 months and then ARS for another 3 months after a wash out period of 14 days. All included patients received a primary impression followed by a centric relation record and a protrusive record for the fabrication of the splints. All splints were designed and then printed. Pain was evaluated using the Visual Analog Scale (VAS), an easy subjective proportion of pain intensity using a scale from 0 to 10, where 0 indicates no pain and 10 indicates high intensity.

Statistical analysis used: An independent t-test was performed for both groups at each fixed time interval.

Results: There was a statistically significant difference within absolute change in pain reduction for both groups over the 3-month follow-up period. During the 1st week, Group B showed a greater pain reduction compared to Group A (0.43 vs. 0.32, respectively; P = 0.0001). However, at the 2nd week, 1 month, 2 months, and 3 months, Group A demonstrated greater pain reduction than Group B, with the values of (0.87, 1.5, 1.54, and 1.82) for Group A and (0.81, 1.19, 1.43, and 1.78) for Group B, respectively (P = 0.0001).

Conclusion: Within the limitations of this study, both splints are considered reliable treatment options for patients with anterior disc displacement. The ARS initially demonstrated a greater improvement in pain compared to the SS. However, after the 3-month follow-up period, no significant difference was observed between the two splints.

3d打印前路复位夹板与稳定夹板治疗前盘移位复位患者:一项随机交叉临床试验
目的:本研究的目的是比较数字构建稳定夹板(SS)和前路复位夹板(ARS)对前路椎间盘移位复位(DDWR)患者疼痛的改善。设置与设计:本试验为交叉随机对照试验。材料与方法:选取20例经磁共振成像诊断为椎间盘前移位的患者。所有纳入的患者均符合纳入标准,均有疼痛,均为前路DDWR。他们使用密封的信封被随机分为两组。A组患者接受ARS治疗3个月,洗脱期14天后再接受SS治疗3个月;B组患者接受SS治疗3个月,洗脱期14天后再接受ARS治疗3个月。所有纳入的患者都接受了主要印象,然后是中心关系记录和夹板制造的突出记录。所有的夹板都是设计好然后打印出来的。使用视觉模拟量表(VAS)评估疼痛,这是一种简单主观的疼痛强度比例,使用从0到10的量表,其中0表示无疼痛,10表示高强度。采用统计学分析:在每一固定时间间隔对两组进行独立t检验。结果:在3个月的随访期间,两组疼痛减轻的绝对变化有统计学意义。第1周,B组疼痛减轻程度明显高于a组(分别为0.43比0.32;P = 0.0001)。然而,在第2周、第1个月、第2个月和第3个月,A组疼痛减轻程度明显高于B组,A组疼痛减轻程度分别为(0.87、1.5、1.54、1.82)和B组疼痛减轻程度分别为(0.81、1.19、1.43、1.78)(P = 0.0001)。结论:在本研究的局限性内,两种夹板被认为是治疗前椎间盘移位患者的可靠选择。与SS相比,ARS最初表现出更大的疼痛改善。然而,在3个月的随访期后,两种夹板之间没有观察到显著差异。
