Beschreibung
Zusammenfassung:	The invention provides a photo-thermal curing resin composition and a preparation method and application thereof. The resin composition comprises a combination of a prepolymer, a monomer, a photoinitiator, a thermal initiator, fumed silica and glass powder in specific parts, the photoinitiator in specific parts is added to be matched with the thermal initiator, the completion rate of a curing reaction is increased, the resin composition is more sufficiently cured, and the monomer residual rate after curing is lower. Specific parts of fumed silica and barium-containing glass powder are also added as fillers, so that the hardness, strength and wear resistance of the resin composition are effectively enhanced, and a product obtained by performing 3D printing on the finally obtained resin composition completely meets the requirements of serving as a temporary crown bridge. 本发明提供一种光热固化的树脂组合物及其制备方法和应用，所述树脂组合物包括特定份数的预聚物、单体、光引发剂、热引发剂、气相二氧化硅和玻璃粉的组合，通过添加特定份数的光引发剂搭配热引发剂，提高了固化反应的完成率，使所述树脂组合物固化更加充分，固化后的单体残留率更低；且还添加特定份数的气相
