PURPOSE:To prepare a fitting article in which the deformation due to the polymerization contraction is little, by carrying out polymerization by means of partially irradiating light successively towards from the outer edge part of a prescribed shape of the resin in working to the center part when the photo-polymerization type dental resin is prepared. CONSTITUTION:A plaster model is prepared as working model, and parallel lines are drawn at 5mm intervals on the model by using a pencil, and a mold separating agent is applied, and the photo-polymerization type dental resin is padded slightly less than the working model, and the dental resin at the irradiation port top-edge tip is light-irradiated by a dental light projector. Irradiation is carried out in the order from the outer edge part to the center part in each strip-shaped region divided by the lines of pencil. In the light irradiation, one strip is light-irradiated, and other parts are shielded from light. Irradiation is performed through the slow reciprocating movement for the irradiated position in each strip-shaped region. |
