The feeling of hardness, stickiness and the rate of cutting during the preparation of a tooth were compared using an extracted tooth, melamine resin and crystalline glass ceramics model tooth (Bioram M) which are used in dental education and practice. Diamond burs were used with an air-turbine handpiece in this experiment. The results indicated that Bioram M had the desirable characteristics of a model tooth and there was a strong resemblance feeling of cutting between Bioram M and a natural vital tooth.
使用牙科教育和实践中使用的离体牙、三聚氰胺树脂和结晶玻璃陶瓷模型牙（Bioram M），比较了牙齿预备过程中的硬度、粘性和切割速率。本实验使用气动涡轮手机和金刚石车针。结果表明，Bioram M具有模型牙所需的特性，并且Bioram M与天然活牙之间在切割感觉上有很强的相似性。
