Abstract
This invention relates to methods for making a three-dimensional dental prosthesis using ink-jet printing systems. An ink-jet printer is used to discharge light-curable, wax-like polymerizable material in a layer-by-layer manner to build-up the prosthesis. The methods are particularly useful for making integrated dentures containing a set of artificial teeth. The denture base and set of teeth are made of light-curable, wax-like polymerizable materials comprising a mixture of monomer, oligomer, and light sensitizer. The wax-like materials are dimensionally stable in their uncured states. The denture base and artificial teeth are later light-cured to form a polymerized denture product having high flexural modulus and flexural strength.
