Abstract:
Photo-curable compositions for artificial teeth and denture base and a method for manufacturing denture by a three-dimensional printing system are provided. The compositions include photo-curable organic compounds, surface modified nano-sized inorganic filler, photo-initiator, colorant, and stabilizer. The composition is in a viscous liquid state having 1500-5000 cps at ambient temperature and has a low viscosity of 50-500 cps at jetting temperature or dispensing temperature. The composition also has an excellent curing rate for three-dimensional printing. Using the compositions, denture having a distinctive denture base and a set of artificial teeth can be manufactured via an inkjet type or digital light process type three-dimensional printing according to Computer Aided Design (CAD) data.
