ABSTRACT:
A method of making solid die dental models is provided, comprising preparing an impression of a dental structure and fabricating a dental model using said impression by depositing therein a flowable modeling material which self-sets under ambient conditions to a substantially solid elastomeric state. The flowable modeling material preferably has an initial viscosity of less than about 30,000 cps, and preferably sets to a substantially solid state in less than about an hour to provide a solid elastomeric state having a durometer hardness of at least about 60. The resulting dental model can be employed for construction of accurate and precise composite dental restorations.
