Abstract

Some embodiments relate to a photothermal-curing resin composition, and a preparation method therefor and the use thereof. The resin composition includes a combination of specific parts of a prepolymer, a monomer, a photoinitiator, a thermal initiator, fumed silica and a glass powder. By means of adding specific parts of the photoinitiator in conjunction with the thermal initiator, the completion rate of a curing reaction is increased, the resin composition is more thoroughly cured, and the residual monomer rate after curing is lower, and specific parts of the fumed silica and barium-containing glass powder are further added as fillers, such that the hardness, strength and wear resistance of the resin composition are effectively enhanced; therefore, a product resulting from the 3D printing of the finally obtained resin composition completely meets the requirements for being used as temporary crowns and bridges.

Abstract

Disclosed are a dental gradient color-resin ceramic restoration material and a preparation method thereof. The method includes: preparing at least two paste materials with different colors, respectively dispersing the paste materials with different colors at a certain speed and under a vacuum of -0.01-0.1 MPa to obtain at least two granular materials with different colors having an average size of 0.1 mm to 5 mm; spreading the at least two granular materials with different colors to be flat in a mould in sequence to obtain at least two layers, and then tightly combining the at least two layers at a pressure of 0.5-5 MPa to obtain a semi-finished product of a gradient color-resin ceramic restoration material; polymerizing and curing the semi-finished product at 60-200° C. and 2-50 MPa to obtain a multilayer gradient color-resin ceramic restoration material.

Abstract

Provided in the present invention are a photothermal-curing resin composition, and a preparation method therefor and the use thereof. The resin composition comprises a combination of specific parts of a prepolymer, a monomer, a photoinitiator, a thermal initiator, fumed silica and a glass powder. By means of adding specific parts of the photoinitiator in conjunction with the thermal initiator, the completion rate of a curing reaction is increased, the resin composition is more thoroughly cured, and the residual monomer rate after curing is lower; and specific parts of the fumed silica and barium-containing glass powder are further added as fillers, such that the hardness, strength and wear resistance of the resin composition are effectively enhanced; therefore, a product resulting from the 3D printing of the finally obtained resin composition completely meets the requirements for being used as temporary crowns and bridges.

Abstract

The present invention provides a high-strength and high-transmittance lithium disilicate glass ceramic, and a preparation method therefor and an application thereof. According to the present invention, a lithium disilicate glass ceramic with lithium disilicate as a main crystal phase and with lithium metasilicate, lithium phosphate, or quartz as an impurity phase is prepared by optimizing a raw material ratio and regulating and controlling heat treatment conditions, wherein the lithium disilicate crystal has a size greater than 700 nm and an aspect ratio not less than 3. According to the lithium disilicate glass ceramic, the three-point bending strength is 450-750 MPa, the fracture toughness is higher than 3.5 MPa·m1/2, and the optical transmittance at 550 nm of a 1 mm thick sample is adjustable within 10%-80%. The lithium disilicate glass ceramic has excellent properties of high strength and high transmittance, effectively reduces the risk of the chipping of a restoration, well simulates the toughness and light transmittance of a natural tooth, and has good application prospects.

Abstract

Provided in the present invention are a polymerizable monomer composition for dental restoration, a preparation method therefor and the use thereof. The polymerizable monomer composition comprises a combination of a polymerizable monomer, an initiator and a cross-linking agent. By adding the cross-linking agent, the double-bond conversion rate of the polymerizable monomer is improved, and the residual rate thereof is reduced. The addition of the polymerizable monomer composition to a resin ceramic restorative material can make the prepared resin ceramic restorative material have higher strength and toughness, so that when applied to dental restoration, the resin ceramic restorative material can maintain a good form whether during processing or when being worn and used by a patient. In addition, due to the reduction of the water absorption value and the dissolution value of the resin ceramic restorative material and the increase of the mechanical strength thereof, the service life thereof is prolonged, and market requirements are met.
