目前使用的塑料调刀两头呈扁平状 ,较宽大 ,使用时材料常被粘附在调刀上。如果调制极少量的材料 ,常因粘附过多而浪费。如牙齿填充材料的衬底材料 ,每次用量极少 ,而且价格昂贵。如用传统调刀调制 ,则造成很大的浪费。在临床实践中 ,我科医护人员对现有的塑料调刀进行了改进 , At present, the plastic adjusting blades used are flat and relatively wide, and the material is often adhered to the adjusting blade when used. If you modulate a very small amount of material, it is often wasted because of excessive adhesion. Substrate materials such as dental filling materials are used in small quantities at a time and are expensive. Such as the use of traditional knife modulation, it will cause a lot of waste. In clinical practice, our medical staff improved the existing plastic knife adjustment.
