Abstract: A dental article such as a crown is fabricating by layering one or more preformed shells of SMC material onto an understructure. The understructure may be fabricated from any suitably strong material for use in replacing dentition. At the same time, a number of SMC shells may be used to provide a finished dental article having a natural-looking, multi-chromatic appearance. The SMC material(s) may be cured to provide an exterior hardness suitable for use in dental applications.
