DENTAL CERAMIC FRAME, PREPARATION OF THE SAME AND DENTAL PROSTHESIS COMPRISING THE SAME

摘要

A dental ceramic frame (10, 20, 30, 50) having two or more core elements (11, 12, 13, 21, 22, 23, 31, 32, 33, 51, 52, 53) arranged in series, characterized in that adjacent core elements are bonded with each other to thereby form a single−piece construction, and bonding portions (14, 15, 26, 27, 34, 35) between the adjacent core elements contain a glass component in a content of 10 wt % or less. The dental ceramic frame (10, 20, 30, 50) is superior in mechanical strength characteristics, as compared to conventional frames such as a ceramic frame in a bridge form having a glass bonding layer and a frame comprising a porous ceramic impregnated with a glass component.
