Embodiment 1

[0029] (1) Preparation of resin system: Stir bisphenol A glycidyl methacrylate and triethylene glycol dimethacrylate for 12 hours in a ratio of 6:4, and then add 0.5% benzyl peroxide Acyl, continue to stir for 12h.

[0030] (2) Preparation of the porous barium glass-ceramic body: Weigh an equal amount of silanized barium glass-ceramic powder with an average particle size of 0.18, 0.4, 0.7 and 1.0 μm in total, 6 g, and rotate in both directions (revolution: 2000 rpm; rotation: 300 rpm ) after mixing evenly, add 2ml of 3% polyvinyl alcohol aqueous solution to infiltrate evenly, place the powder in a 60°C oven to dry, transfer the powder to a steel mold, apply a pressure of 5MPa, and press for 2Min to form a porous barium glass-ceramic body , Porosity 25±5%.

[0031] (3) Resin system permeates the porous barium glass ceramic body: the porous barium glass ceramic body prepared in step (2) is half-immersed in the resin system prepared in step (1), and the whole is placed in a vacu...

Embodiment 2

[0034] (1) Preparation of resin system: Stir bisphenol A glycidyl methacrylate and triethylene glycol dimethacrylate at a ratio of 7:3 for 12 hours and mix well, then add 0.5% benzyl peroxide Acyl, continue to stir for 12h.

[0035] Steps (2)-(4) are the same as steps (2)-(4) in Example 1.

Embodiment 3

[0037] (1) Preparation of resin system: Stir bisphenol A glycidyl methacrylate and triethylene glycol dimethacrylate for 12 hours in a ratio of 3:7, and then add 0.5% benzyl peroxide Acyl, continue to stir for 12h.

[0038] Steps (2)-(4) are the same as steps (2)-(4) in Example 1.

Abstract

The invention relates to a cutting resin permeable glass ceramic material for dental restoration and a preparation method thereof, and the technical problems that the existing material are uneven in component distribution and not ideal in cutting performance are solved. The cutting resin permeable glass ceramic material comprises a resin matrix, a reinforced inorganic filler and a toner, and the reinforced inorganic filler is the barium silanization glass ceramic powder with gradient particle size distribution, the resin matrix is an acrylic monomer, and the toner is ferric oxide and zirconiumoxide. The invention further provides a preparation method thereof. The preparation method can be applied to the field of preparation of materials for dental restoration.

Description

technical field [0001] The invention relates to the field of dental materials, in particular to a machinable resin-infiltrated glass-ceramic material for dentistry and a preparation method thereof. Background technique [0002] Computer-aided design (computer-aided design) / computer-aided manufacturing (computer-aided manufacturing) referred to as CAD / CAM is a high-tech technology widely used in the field of machinery manufacturing in the 1970s, which greatly improves production efficiency. As early as the early 1970s, the research of CAD / CAM technology in the field of oral restoration has also begun to take shape. Due to the reduction of operating steps and shortened production time, this technology can complete the production of restorations in one visit. The rapid development of the field has greatly promoted the scope of its application in stomatology. At present, the application of CAD / CAM technology in the field of oral restoration has expanded from the production of a...
