Description
Technical Field
The invention relates to preparation of an enhanced dental glass ion water valve, and belongs to the field of dental materials.
Background
The glass ion water valve is used as an excellent dental restoration material and has the characteristics of no toxicity, aesthetic property, biocompatibility, low curing shrinkage, low dental pulp irritation, long-term fluoride ion release and the like. Meanwhile, the glass ion water portal has similar thermal expansion coefficient with the teeth and can form effective chemical bonding with the teeth, so that the occurrence of micro leakage can be reduced, and secondary caries can be inhibited. At present, the glass ion water valve is widely applied to aspects of tooth defect repair, caries filling, pit and groove sealing, orthodontic and the like. However, glass ion water portal is fragile and low in mechanical strength, and cannot completely replace composite resin for filling cavities and repairing tooth bodies in a constant tooth function area, so that improvement of the mechanical strength is needed.
At present, a lot of researches on using inorganic fiber reinforced glass ion water heater, such as Hammouda, garoushi and Sharafeddin, select glass fiber reinforced glass ion water heater, and the researches show that the glass fiber can remarkably improve the mechanical strength of the glass ion water heater, because the glass fiber can transfer stress when a substrate is subjected to shearing force or pressure, and inhibit continuous expansion of cracks, thereby preventing the substrate from breaking; and the glass fibers do not cause the system to shrink or expand in volume. However, as with glass fiber, the problem of poor interfacial adhesion between the inorganic fiber and the glass ion water heater matrix is common, and the inorganic fiber may be separated from the matrix in the use process, so that potential damage is caused to important organs in human body, and meanwhile, the poor interfacial adhesion also causes unsatisfactory reinforcing effect of the inorganic fiber. Therefore, the improvement of the interfacial adhesion between the inorganic fiber and the glass ion cement is of great significance.
