Teaching model for tuition of treatment of caries

摘要

The bodies (1, 1') have plastic layers with degrees of hardness based on a natural tooth. Receiving recesses (11, 11') are approximal- and/or occlusal-formed in the plastic layers. A fusion lesion body (12) is inserted into the receiving recesses. Form and size of the lesion body are adapted to caries infestation of the natural tooth. The lesion body is firmly connected with the receiving recesses. The lesion body is made of open-pore inorganic-ceramic material. The lesion body is filled with capillary-common plastic monomer doped with fluorescent dye.
