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.

A method of making a dental model, comprising the steps of:
- 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 having a durometer hardness of at least about 60.
A method of making a dental restoration, comprising:
- a) preparing an impression of a dental structure comprising a tooth prepared for implantation of a composite restoration, using an impression material which self-sets to a substantially solid state under ambient conditions;
- b) depositing into the impression a flowable modeling material which self-sets under ambient conditions to a substantially solid elastomeric state having a durometer hardness of at least about 60;
- c) depositing into substantial co-extensive contact with said flowable modeling material a deformable base material which self-sets to a substantially solid state under ambient conditions;
- d) setting said flowable modeling material and said deformable base material to provide a unitary dental model comprising a replicate tooth corresponding to said prepared tooth;
- e) removing said dental model from said impression;
- f) preparing a dental restoration by depositing a curable composite material onto said replicate tooth;
- and
- g) curing said curable composite material in situ in said replicate tooth creating the dental restoration suitable for implantation in the prepared tooth.
