摘要:

目的 比较经验丰富的口腔医师和初级医师使用咬合平面板确定全口义齿咬合平面的准确性。方法 15位经验丰富的医师和15位初级医师分别使用咬合平面板确定仿真头颅模型蜡堤的咬合平面,测量蜡堤上咬合平面与参考平面的夹角,分析2组测量值之间的差异。结果 经验丰富的医师和初级医师所确定的前牙区咬合平面与参考平面的夹角分别为(0.2±0.1)°和(0.6±0.2)°,差异有统计学意义(t=-4.668,P<0.001),但夹角都接近于0°,差异无临床意义。经验丰富的医师和初级医师所确定的后牙区咬合平面与参考平面的夹角分别为(0.9±0.4)°和(3.4±0.6)°,差异有统计学意义(t=-13.378,P<0.001),经验丰富的医师所确定的咬合平面与参考平面的夹角更接近0°。结论 对于经验丰富的口腔医师,使用咬合平面板确定咬合平面是一种精度较高的方法。初级医师使用咬合平面板确定前牙区咬合平面也很准确,但对后牙区咬合平面的观测能力较差,需要在这方面加强训练。

Abstract:

Objective To compare the angles of the reference plane and different occlusal plane determined by experienced dentists and primary dentists in order to study the effect of occlusal plane plate.Methods 15 experienced dentists and 15 newly-graduated dentists independently fabricated wax occlusal rims by the Fox plane-guide. The intersection angle between the reference plane and the occlusal plane was measured and compared.Results There was statistically significant differences (t=-4.668, P<0.001) between the experienced dentists (0.2±0.1) and newly-graduated dentists (0.6±0.2) in the intersection angles of anterior occlusal plane and reference plane, but there was no clinical references because both are closer to zero degrees. A significant differences (t=-13.378, P<0.001) can be detected between the experienced dentists (0.9±0.4) and newly-graduated dentists (3.4±0.6) in the intersection angles of posterior occlusal plane and reference plane, which the former was more closer to zero degrees than the latter.Conclusion Both the experienced dentist and newly-graduated dentists can make the anterior occlusal rim accurately with the help of the Fox plane-guide. But the newly-graduated dentists are less capable to observe and orient the posterior occlusal rim compared to experienced dentists, and need more training in this area.
