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

摘要

The present invention provides a dental ceramic frame (10, 20, 30, 50) which is superior in terms of mechanical strength characteristics compared with conventional bridge-shaped ceramic frames that have glass joining layers or frames consisting of porous ceramics impregnated with glass.;This dental ceramic frame (10, 20, 30, 50) comprises two or more core elements (11, 12, 13, 21, 22, 23, 31, 32, 33, 51, 52, 53) disposed in series, and adjacent core elements are joined to each other to form an integral unit. This dental ceramic frame is characterized in that the content of the glass component in the joining portions (14, 15, 26, 27, 34, 35) between the core elements is 10 wt% or less.
