Embodiment 1
[0079]
[0080] The intraoral scanner is used to scan and obtain the three-dimensional shape data of the tooth to be restored and the adjacent teeth, and the obtained three-dimensional shape data is directly imported into the CAD software, and the crown shape is designed on the CAD software platform, and the obtained crown shape data is imported into the 3D printer;
[0081] According to the formula 1 in Table 1, the components are selected, mixed evenly, put into a platinum crucible and melted at a high temperature in a muffle furnace, the melting temperature is 1250 ° C; the molten glass liquid is water quenched to form a lithium disilicate glass frit, and the obtained two Lithium silicate glass frit is pulverized by airflow to obtain particle size D 50 Lithium disilicate glass-ceramic powder of 10 μm;
[0082] The obtained particle size D 50 Lithium disilicate glass-ceramic powder with a thickness of 10 μm was put into the hopper of a 3D printer, and the 3D printer was u...
Embodiment 2
[0087]
[0088] The intraoral scanner is used to scan and obtain the three-dimensional shape data of the tooth to be restored and the adjacent teeth, and the obtained three-dimensional shape data is directly imported into the CAD software, and the crown shape is designed on the CAD software platform, and the obtained crown shape data is imported into the 3D printer;
[0089] According to the formula 2 in Table 1, the components were selected, mixed evenly, put into a platinum crucible and melted at a high temperature in a muffle furnace at a melting temperature of 1650°C; the molten glass liquid was water-quenched to form a lithium disilicate glass frit, and the resulting two Lithium silicate glass frit is crushed by air flow to obtain particle size D 50 Lithium disilicate glass-ceramic powder of 20 μm;
[0090] After comparing the tooth to be restored and the adjacent tooth with the color guide, obtain the color information, and select the colorant and fluorescent agent sho...
Embodiment 3
[0096]
[0097] Use a 3D scanner to scan to obtain the 3D shape data of the tooth to be restored and the adjacent teeth, and the obtained 3D shape data are directly imported into the CAD software, and the crown shape is designed on the CAD software platform, and the data of the crown shape is imported into the 3D printer;
[0098] According to the formula 3 in Table 1, the components were selected, mixed evenly, put into a platinum crucible and melted at a high temperature in a muffle furnace, the melting temperature was 1450°C; the molten glass liquid was water-quenched to form a lithium disilicate glass frit, and the obtained two Lithium silicate glass frit is crushed by air flow to obtain particle size D 50 Lithium disilicate glass-ceramic powder of 15 μm;
[0099] After comparing the tooth to be restored and the adjacent tooth with the shade guide, obtain color information, and select the colorant and fluorescent agent as shown in 2-3 in Table 2 according to the obtained...
