近年来的工作实践中,我们总结了牙体形态模型的一种制作方法,兹介绍如下: 材料: 石膏:选用西安市石膏厂生产的“人造石”石膏,这种石膏坚硬、有一定强度,收缩较小,翻出的模型光滑、细致、气泡少。 模型蜡的配制:模型蜡应有一定强度,其软点在60～55℃,溶点在57～60℃为宜,加热后要有良好的 In recent years, the work practice, we have summarized a method of making dental morphology model, it is introduced as follows: Material: Gypsum: Selection of gypsum plant in Xi'an production of “artificial stone” gypsum, the gypsum hard and have a certain intensity, Shrink smaller, pulls out the model is smooth, detailed, less bubbles. Model wax preparation: Model wax should have a certain intensity, the soft point at 60 ~ 55 ℃, the melting point is appropriate at 57 ~ 60 ℃, after heating to have a good
