Abstract

The invention belongs to the field of dentistry, and particularly relates to a dlp type 3d printing photocuring material for a clinical dental temporary crown, which takes nano organic-inorganic hybrid UV resin, high-strength aliphatic urethane acrylate, high-toughness aliphatic urethane acrylate and a free radical acrylate monomer diluent as main bodies and is matched with an inorganic silver antibacterial agent and a pigment, the dLp type 3D printing photocuring material for the clinical dental temporary crown is prepared from a 385nm wavelength free radical system composed of a photoinitiator, and the problems of poor material performance stability, poor size stability, poor toughness, poor mechanical property, medical risk and the like are effectively solved by using a special printingprocess and a post-treatment process.

Description

technical field

[0001] The invention belongs to the field of dentistry, and in particular relates to a dlp type 3D printing light-curing material for clinical dental temporary crowns. Background technique

[0002] A temporary crown, also known as a temporary crown, is a temporary full crown that is temporarily bonded in the patient's mouth after the preparation of the tooth for crown restoration and before the completion of the final crown restoration, and the patient cannot freely wear it. Currently, the temporary crown (bridge) technology used in the clinical dental market mainly uses plastic resin crowns, gun-mixed temporary crown and bridge resins, hand-mixed temporary crown and bridge resins, and self-curing temporary crown and bridge resins. Commonly used materials for crown restoration include zirconia, stainless steel, and polycarbonate. However, the traditional process has the disadvantages of high initial investment cost, long production cycle, high labor cost, lo...
