Abstract

The invention provides a ceramic material and a repair material for improving the surface adhesion of dental zirconia, and a preparation method and a bonding method of the ceramic material and the repair material. The ceramic material comprises SiO2, B2O3, GeO2, Al2O3, Li2O, Nb2O5, Na2O, ZrO2, P2O5 and rare earth oxide. The ceramic material provided by the invention contains GeO2, on one hand, the GeO2 can replace SiO2 in the ceramic material, the high-temperature melting temperature of glass is reduced, and the production cost is saved; on the other hand, the ratio of Si to Li can be effectively reduced, so that fine and uniform lithium disilicate crystals are formed after crystallization, and the bonding strength with a zirconium oxide matrix is improved.

Description

technical field [0001] The invention belongs to the technical field of dental materials, and relates to a ceramic material for improving the surface adhesiveness of dental zirconia, a restoration material, a preparation method and a bonding method thereof. Background technique [0002] With the development of CAD / CAM technology, all-ceramic restoration materials have gradually become one of the main restoration materials selected by patients due to their high strength, good biological properties and excellent aesthetic effects. The types of all-ceramic restoration materials mainly include yttrium stabilized zirconia (Y-TZP), lithium disilicate glass ceramics, feldspar glass ceramics and leucite glass ceramics, among which zirconia has ultra-high bending strength ( >800Mpa) and fracture toughness (>5Mpa m 1 / 2 ), are widely used in veneers, inlays, onlays, single crowns and bridges with three units or more. However, compared with other types of all-ceramic restoration ...
