摘要
目的:记录颞下颌关节盘移位患者和正常人下颌运动时髁突运动轨迹,分析关节盘移位对髁突运动的影响。方法:选取双侧不可复性关节盘移位(DDwoR)和可复性关节盘移位(DDwR)患者各18例,健康对照(HC)10例。电子髁突运动轨迹描记仪记录受试者下颌开闭口、前伸后退时髁突铰链轴运动轨迹,计算髁突最大位移(Smax)、髁突位移为5 mm时矢状面髁道斜度(SCI5)、髁突最大位移时矢状面髁道斜度(SCI),矢状面上髁突往返运动重合性(R)。采用方差分析比较3组间差异。结果:开闭口运动,DDwoR组Smax、SCI5显著小于DDwR组和HC组;DDwR组SCI显著小于DDwoR组和HC组;DDwR组R显著大于DDwoR组和HC组。前伸后退运动,DDwoR组SCI5、SCI显著小于DDwR组和HC组;DDwR和DDwoR组R明显大于HC组。结论:不同类型颞下颌关节盘移位患者的髁突运动轨迹具有不同特征,为颞下颌关节盘移位临床诊治提供参考。
Objective:To explore the effect of disc displacement on condylar movements in patients with temporomandibular joint disc displacement.Methods:Eighteen patients with bilateral disc displacement without reduction(DDwoR),18 patients with bilateral disc displacement with reduction(DDwR),and 10 healthy controls(HC)were included.The trajectories of the condylar hinge axis when doing opening-closing and protrusive-retrusive movements were recorded by computer aided diagnosis axiograph,respectively.The maximum displacement of condyle(Smax),the sagittal condylar track inclination when condylar displacement was 5mm(SCI5),the sagittal condylar track inclination when condylar displacement was maximum(SCI),and reproducibility of condylar movement on the sagittal plane(R)were calculated.Variance analysis was used to compare the differences among the three groups.Results:During opening-closing movement,Smax and SCI5 in DDwoR group were significantly lower than those in DDwR group and HC group.SCI of DDwR group was lower than that of DDwoR group and HC group while R of DDwR group was significantly greater than that of DDwoR group and HC group.When doing protrusive-retrusive movement,the SCI5 and SCI in DDwoR group were significantly lower than those in DDwR group and HC group.The R of DDwR and DDwoR group was significantly higher than that of HC group.Conclusion:The condylar movement trajectories of patients with different types of disc displacement have different characteristics,providing reference for clinical diagnosis and treatment of temporomandibular joint disc displacement.
