During restoration work in which a photopolymerizable dental restorative member is applied to the damaged denture base surface and polymerized and cured, the restorative member made of the applied photopolymerizable resin prepolymer is irradiated with light to polymerize and cure it. Is widely practiced. Recently, visible light has been used as irradiation light instead of ultraviolet light, which is harmful to the human body. At the time of implementation, a light emitting lamp with a spherical reflecting mirror is installed downward at the uppermost position just above the turntable for mounting the visible light polymerizable dental restorative member, and an infrared ray removing filter is placed below it. The visible light polymerizable dental restorative member arranged at the lowermost position is irradiated with visible light. However, the visible light polymerizable dental restoration member on the upper surface of the turntable is completely irradiated with visible light from above, but it is difficult to irradiate the side portion of the dental restoration member with visible light from above. Polymerization and curing by irradiation with visible light were not achieved. Further, the light emitted from the above-mentioned light-emitting lamp cannot sufficiently remove the infrared rays even if a filter is interposed, and the light distribution becomes non-uniform, causing local heat generation and unevenness in the polymerization and curing of the visible light-polymerizable resin. Occurs, and the molding accuracy of the product
The material characteristics were deteriorated. Further, the emitted light from the light emitting lamp is not a uniform parallel light beam, and there is a problem that uneven irradiation light occurs unless the distance from the light emitting lamp to the photopolymerizable resin of the dental restorative member is precisely adjusted.

定性も十分に確保できる。In the device of the present invention, the visible light emitted from the upper side to the lower side, particularly the visible light of the outer peripheral portion of the turntable 8, is
The semicircular visible light-reflecting ring body 17 disposed near the outer circumference of the turntable 8 hits the tapered surface and is laterally refracted to irradiate the side of the visible light polymerizable dental restoration member 8 on the surface of the turntable 8. To be done. As a result, the dental restorative member 8 on the turntable surface is irradiated with vertical light rays from above and laterally from the lateral side at the lower portion, and is irradiated with visible light as a whole. It is polymerized and cured.

It can be polymerized and cured evenly by irradiation with light. Convex lens 6
Since the light beam passing downward from the photocuring member is a uniform parallel light beam, even if the height of the photopolymerizable dental restorative member 8 on the turntable 7 is at any position, the photopolymerizable dental restorative member is uniformly illuminated. Since the visible light is applied, it is not necessary to precisely adjust the height of the dental restoration member as in the prior art. Further, since the light emitting lamps are arranged in the lateral direction by using the tilted reflecting mirror, the height of the device can be reduced, and the device is compact and sufficient installation stability can be secured.

A dental restoration member 7 made of a visible light-polymerizable resin prepolymer placed on the surface of the turntable 8 is arranged in the lower portion of the housing of the device 1 of the present embodiment, and in the vicinity of the outer periphery of the turntable 8. A visible light-reflecting semi-circular ring body 17 having a tapered inner surface whose inner diameter is reduced downward is fixed.

ものとしてよい。In the upper part of the apparatus 1, a plane reflecting mirror 4 of infrared transmitting / visible ray reflecting type is installed above the turntable 8 and inclined forward and downward at an angle of 45 °. A heat radiating plate 5 is attached to the back surface of the plane reflecting mirror 4 to avoid heat generation due to light irradiation from the light emitting lamp 2. Further, a convex lens 6 is disposed horizontally below the tilted plane reflecting mirror 4. Further, on the side of the plane reflecting mirror 4, a light emitting lamp 2 having a spherical reflecting mirror 2a as an emission light source is arranged toward the plane reflecting mirror 4 surface. Since the light emitting lamp 2 is a light source for polymerizing and curing the visible light-polymerizable resin prepolymer, a lamp having a large amount of light, for example, a halogen lamp is used. The back surface of the light emitting lamp 2 is covered by a spherical reflecting mirror 2a, and most of the emitted light rays emitted from the light emitting lamp 2 to each direction are focused forward. Instead of the light emitting lamp 2 having the spherical reflecting mirror 2a, a spherical reflecting film may be formed in the light emitting lamp 2 by metal vapor deposition.

る。In the photopolymerization device having the above structure, since the light emitting point of the light emitting lamp 2 is set outside the focal point of the spherical reflecting mirror 2a and inside the spherical center thereof, the reflected light rays are along the optical axis in the lateral direction. And the light is condensed by the plane reflecting mirror 4 inclined at 45 °.
Is condensed and reflected on the mirror surface of. Infrared rays are transmitted through the reflecting mirror 4 and are removed by the infrared radiation plate 5 on the back surface.
Visible rays are refracted and reflected, and become divergent rays, which are projected onto the convex lens 6 below. Further, the divergent light beam from the reflecting mirror 4 passes through the convex lens 6 to be converted into a parallel light beam and is irradiated downward. The emitted light beam directly emitted from the light emitting lamp 2 without passing through the spherical mirror 2a is refracted and reflected by the flat reflecting mirror 4, projected onto the convex lens 6 below the installation position, passes through,
The parallel light rays are applied to the visible light-curable dental restoration member 7 below. As described above, since the passing light rays that have passed through the convex lens 6 are emitted downward as uniform parallel light rays,
Regardless of the height position of the lower photopolymerizable dental restorative member, uniform visible light is irradiated at each height position.

いる。Reference numeral 9 is an air supply / exhaust device, 9a is an exhaust device, and 9b is an air supply device. First, outside air is introduced into the housing of the device by the air supply device 9b through the dust removing filter 15. The air becomes an air flow indicated by an arrow to cool the visible light polymerizable dental restorative member on the turntable 8, and then passes through the gap 30 between the convex lens 6 and the front lid 12 to rise and to radiate infrared rays. 5 is cooled, and further passes through the ventilation holes 3a, 3a formed in the upper separating plate 3,
The light-emitting lamp 2 is cooled, and then is sucked to the outside by the exhaust device 9a to become hot air and is discharged to the outside. At this time, the inside of the housing is roughly divided into two chambers, the upper chamber and the lower chamber, by the separator plate 3 and the convex lens 6 and the like. The temperature of the photopolymerizable dental restorative member does not rise and does not flow into the lower chamber, which requires relatively low temperature retention. Furthermore, by extending the inclined plate 3b for adjusting the supply airflow obliquely downward from the end of the separator 3, the airflow introduced into the room by the air supply device 9b is concentrated on the visible light polymerizable dental restoration member 7. Can be sent to. In addition, turntable 8

くなる。According to the photopolymerization apparatus for a visible light polymerizable dental restorative member of the present invention, the visible light in the vertical direction and the visible light in the lateral direction from the lower side are visible light polymerizable dental on the turntable. The restoration member is irradiated and the cooling by ventilation is secured, so that it can be uniformly polymerized and cured as a whole. Also,
In the invention in the case of irradiating the downward passing light beam as a uniform parallel light beam, the photopolymerizable dental restorative member on the turntable may be photopolymerizable at any height position. The dental restorative member can be uniformly illuminated with visible light, eliminating the need to precisely adjust the height of the dental restorative member.
