中文摘要

目的 评估治疗前关节盘形态学特征及盘髁角度对前伸再定位咬合板(ARS)治疗可复性关节盘前移位(ADDwR)效果的影响。 方法 根据纳入排除标准共纳入11例ADDwR患者,分析ARS治疗前后核磁共振成像影像资料及Helkimo指数,评估治疗前患者关节盘长度、厚度、形态分类对患者治疗后临床症状及关节盘形态学特征、盘髁角度及临床症状的影响。 结果 经ARS治疗,所有ADDwR患者主观症状指数(Ai)和临床症状指数(Di)下降,关节盘长度增加,厚度降低。其中轻微前移位者或1型关节盘者Ai降至0且Di下降最明显,轻度前移位者(至8.65 mm±1.79 mm)或5型关节盘者(至10.71 mm±2.62 mm)长度增长最明显,轻微前移位者关节盘厚度降低最明显(至3.08 mm±0.51 mm)。 结论 ARS治疗效果与关节盘移位程度及形态特征相关,为临床治疗决策提供了依据。

英文摘要

ObjectiveThis study aimed to evaluate the effect of disc morphology and disc-condyle angle on the treatment of anterior repositioning splint (ARS) for anterior disc displacement with reduction (ADDwR).MethodsOn the basis of the inclusion and exclusion criteria, a total of 11 patients diagnosed with ADDwR were included. The effects of changes in disc length, thickness, and morphology classifications on the clinical symptoms, disc morphology parameters, and disc-condyle angles after ARS treatment were evaluated using magnetic resonance imaging and the Helkimo index.ResultsAfter ARS treatment, the Ai and Di of all patients with ADDwR decreased, the disc length increased, and the thickness decreased. The Ai of patients with slight ADDwR and those with type 1 joint discs was reduced to 0, with the most significant decrease observed in Di. The disc length of mild ADDwR (increased to 8.65 mm±1.79 mm) and type 5 disc (increased to 10.71 mm±2.62 mm) significantly increased the most. The disc thickness of slight ADDwR decreased to 3.08 mm±0.51 mm significantly.ConclusionThe therapeutic effect of ARS is correlated with the displacement degree and morphological features of the disc, providing evidence for clinical treatment decisions.
