Embodiment 1

[0055] refer to Figure 1 to Figure 4 , the present invention provides a molding method of a resin veneer, wherein the resin veneer is attached to the tooth surface of a patient, the method comprising:

[0056] S100, in the rigid outer layer transparent guide plate 11, the elastic inner layer transparent silicone rubber female mold 12 for forming a resin veneered tooth model on the patient's teeth 4 is turned over, thereby forming the outer layer transparent guide plate 11 and The molding die 1 of the inner layer transparent silicone rubber female mold 12; at the position corresponding to the transparent silicone rubber female mold 12 for forming the resin veneer, the molding device has a transparent The injection hole 13 of the guide plate 11 and the inner transparent silicone rubber female mold 12; the inner contour of the injection hole 13 matches the outer contour of the injection head 2 so that the injection hole 13 accommodates the injection head 2; Preferably, the inje...

Embodiment 2

[0072] refer to Figure 1 to Figure 4 , the present invention provides a resin veneer molding device, the resin veneer molding device includes an outer thermoplastic film guide plate 11, an inner transparent silicone rubber female mold 12 and a high-fill fluid resin injection hole 13.

[0073] According to the above technical scheme, the diameter of the outer thermoplastic film guide plate 11 is 1.5mm, the diameter of the cavity in the direction of the inner transparent silicone rubber female mold 12 is 1.5mm, the side wall of the cavity is retracted downward at 3°, and the high-filler resin injection head 2 It is an injection device with a diameter of 1.5mm, an adduction angle of 3°, and a hole inside. Because the internal transparent silicone rubber has a certain elasticity, when the injection head 2 is inserted into the guide plate 11, the outer hard guide plate 11 has a "lock" for the injection head 2. The inner layer of soft guide plate 11 has the function of squeezing an...

Embodiment 3

[0084] refer to Figure 1 to Figure 4 , the present invention provides a resin veneer molding device, the resin veneer molding device includes an outer thermoplastic film guide plate 11, an inner transparent silicone rubber female mold 12 and a high-fill fluid resin injection hole 13.

[0085] According to the above technical scheme, the diameter of the outer thermoplastic film guide plate 11 is 1.5mm, the diameter of the cavity in the direction of the inner transparent silicone rubber female mold 12 is 1.5mm, the side wall of the cavity is retracted downward at 3°, and the high-filler resin injection head 2 It is an injection device with a diameter of 1.5mm, an adduction angle of 3°, and a hole inside. Because the internal transparent silicone rubber has a certain elasticity, when the injection head 2 is inserted into the guide plate 11, the outer hard guide plate 11 has a "lock" for the injection head 2. The inner layer of soft guide plate 11 has the function of squeezing an...

Abstract

The invention discloses a molding device for a resin veneer for dental cosmetics, and a method for preparing the resin veneer by using the molding device. The molding device for the resin veneer comprises an outer-layer thermoplastic membrane guide plate, an inner-layer transparent silicon rubber female mold and a high-filler fluid resin injection hole. When the molding device is operated inside a mouth of a patient, an improved molding injection technique is implemented according to an atmospheric pressure principle, so that bubbles can be reduced to the maximum extent, and in addition, the resin veneer can be relatively efficiently molded.
