Description
Technical Field
The invention relates to the technical field of oral cavity restoration equipment, in particular to a veneering restoration colorimetric board system and a manufacturing method thereof.
Background
The matching of the color of veneered restorations to natural teeth is one of the main criteria for the success of restorations. At present, when clinical veneering restoration colorimetry is carried out, a restoration colorimetric plate (mainly comprising a Vita 3D Master colorimetric plate) is used for comparing colors of natural teeth, a target color of a veneering restoration is selected, and effective information is not provided for doctors or technicians on how to select porcelain materials and abutment colors. The existing patent technology is continuously improved for the problem, for example, the ceramic veneering of the lithium disilicate enhanced glass ceramic material (IPSe.maxPress) manufactured by the hot-press casting process with the thickness of 0.1-1.0mm is designed for clinical colorimetry, or the cut lithium disilicate enhanced glass ceramic material (IPSe.max CAD) is designed to be shell-shaped, or a dentin color resin substitute material is selected to simulate the color of an abutment (Yijia dentin colorimetric plate), or different color card abutments are manufactured.
