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.

摘要:
The invention describes a dental article comprising zirconium oxide and at least two different coloring substances A and B, substance A showing a light emission in the range of about 470 nm to about 510 nm and substance B showing a light absorption in the range from about 520 nm to about 750 nm. The invention also relates to different processes of producing the dental article e.g. by a process comprising a casting step, a pressing step, or an infiltration step and to the use of certain compositions containing either substance A or substance B for producing such a dental article.

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.
摘要:
Systems and methods for making a monolithic gel body. Some systems can include a substrate, a sol, an ammonia atmosphere. Some methods can include applying a first quantity of the sol to the substrate to form a first coated substrate, and positioning the first coated substrate in the ammonia atmosphere to cure the first quantity of sol to form a first supported gel comprising a first gel supported by the substrate. Such methods can further include applying a second quantity of the sol to the first supported gel to form a second coated substrate comprising the second quantity of sol and the first supported gel. Some methods can include positioning the substrate in the ammonia atmosphere while applying the sol onto the substrate to form a monolithic gel body by a layering process.

Methods for making a layered dental appliance. Some methods of the present disclosure can include providing a solid structure (e.g., a die or a dental core, such as a fully sintered ceramic dental core) having a desired outer shape, and applying a slurry to the solid structure to form a first free form layer on the solid structure. The slurry can include at least one of a glass and a glass ceramic. The method can further include firing the first free form layer on the solid structure, and machining the fired first free form layer to a desired shape to form a first article comprising the solid structure and a first shaped layer. Some methods can further include additional applying, firing, and machining steps to achieve a resulting dental appliance having a desired number of layers. Some methods can include removing the solid structure.
