[Crystalline glass ceramics model teeth].
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.
