Abstract
A fineable dental blank assembly. The assembly can include a blank and a support coupled to the blank to facilitate machining of the blank. The blank can be adapted to be machined to form at least a portion of dental appliance, and can be formed of at least one of a glass, a glass-ceramic, a porcelain, and a ceramic. The support can be formed of at least one of a high melting point metal (or metal alloy) and a ceramic, wherein the blank and the support are separately formed. The assembly can further include a bonding composition positioned between the blank and the support. Other means for coupling the blank and the support can include a direct bond and/or mechanical inter-engagement. The assembly can be configured to withstand temperatures necessary to fire at least a portion of the assembly in a downstream firing process.
