OBJECTIVE
To assess the effectiveness of the stabilization splint (SS) combined with the T-Scan™ III system in the treatment of temporomandibular joint disorder (TMD) with myofascial pain.
METHODS
Forty-eight enrolled patients were randomly assigned to the SS group or T-Scan™-guided SS group. Mandibular Function Impairment Questionnaire (MFIQ), Maximum Comfortable Opening (MCO), Visual Analog Scale (VAS), and Patient Health Questionnaire-9 (PHQ-9) were used as the outcome variables.
RESULTS
The occlusal contacts of patients in the SS plus T-Scan™ group showed lower Occlusal Time (OT), Disocclusion Time (DT), and Asymmetry Index of Occlusal Force (AOF) after occlusal adjustment under the guidance of the T-Scan™. Importantly, the TMD symptoms were alleviated more obviously in SS plus T-Scan™ group, with better scores for MCO and MFIQ.
CONCLUSION
T-Scan™-guided occlusal adjustment of SS can obtain better OT, DT, and AOF, which furthers improvement of the therapeutic effects on TMD with myofascial pain.
目的
评估稳定夹板（SS）联合T-Scan™ III系统治疗伴肌筋膜疼痛的颞下颌关节紊乱病（TMD）的有效性。
方法
将48例入组患者随机分为SS组或T-Scan™引导的SS组。采用下颌功能损害问卷（MFIQ）、最大舒适开口度（MCO）、视觉模拟评分（VAS）和患者健康问卷-9（PHQ-9）作为观察指标。
结果
在T-Scan™引导下进行咬合调整后，SS加T-Scan™组患者的咬合接触显示出更低的咬合时间（OT）、脱离咬合时间（DT）和咬合力不对称指数（AOF）。重要的是，SS加T-Scan™组的TMD症状缓解更明显，MCO和MFIQ评分更高。
结论
T-Scan™引导下的SS咬合调整可获得更好的OT、DT和AOF，进一步提高对伴肌筋膜疼痛的TMD的治疗效果。
