Abstract:
A system and method for making a layered dental appliance. The system can include a mold comprising a negative of an outer shape of a layered dental appliance, and a dental core dimensioned to be at least partially received in the mold. The method can include positioning a first slurry in the mold, and pressing the dental core into the first slurry in the mold to form a first article comprising the dental core and a first layer formed from the first slurry. The method can further include removing the first article from the mold, and firing the first article. The method can further include positioning a second slurry in the mold, and pressing the first article into the second slurry in the mold to form a second article comprising the dental core, the first layer, and a second layer formed from the second slurry.
