AI Technical Summary
Existing 3D printing resin compositions for temporary crowns and bridges exhibit low curing reaction completion rates, insufficient hardness, and poor abrasion resistance, leading to issues such as monomer residue and limited mechanical properties.
A photothermal-curing resin composition comprising specific proportions of prepolymer, monomer, photoinitiator, thermal initiator, fumed silica, and glass powder, which enhances curing completion and mechanical properties through combined photo and thermal initiation, along with the addition of inorganic fillers for improved hardness and abrasion resistance.
The resin composition achieves higher curing reaction completion, reduced monomer residue, and enhanced hardness and abrasion resistance, meeting the requirements for oral restorative materials.
