摘要：
A system and method for making a layered dental appliance. The system can include a first portion comprising a negative of a first layer of a layered dental appliance, and a second portion comprising a positive shape of a second layer of the layered dental appliance. The method can include providing a mold comprising a negative of an outer shape of a layered dental appliance, and positioning a slurry in the mold, forming a first layer of the layered dental appliance. The method can further include providing a solid structure comprising a positive shape of a second layer of the layered dental appliance, and pressing the solid structure into the slurry in the mold.
