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.

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:
Aerogel, calcined articles, and crystalline articles comprising ZrO2. Exemplary uses of the crystalline metal oxide articles include dental articles (e.g., restoratives, replacements, inlays, onlays, veneers, full and partial crowns, bridges, implants, implant abutments, copings, anterior fillings, posterior fillings, and cavity liner, and bridge frameworks) and orthodontic appliances (e.g., brackets, buccal tubes, cleats, and buttons).
