摘要:
A system and method for making a layered dental appliance. The system can include a first mold comprising a negative of a first layer of a layered dental appliance, a second mold comprising a negative of a second layer, and a dental core dimensioned to be at least partially received in the first mold and the second mold. The method can include positioning a first slurry in the first mold, and pressing the dental core into the first slurry 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 first mold, positioning a second slurry in the second mold, and pressing the first article into the second slurry to form a second article comprising the dental core, the first layer, and a second layer formed from the second slurry.
摘要:
Sintered bodies containing zirconia-based ceramic materials and partially sintered bodies that are intermediates in the preparation of the sintered bodies are described. The zirconia-based ceramic material is doped with lanthanum and yttrium. The grain size of the zirconia-based ceramic material can be controlled by the addition of lanthanum. The crystalline phase of the zirconia-based ceramic material can be influenced by the addition of yttrium.
