Description

Dental photopolymerization device

The new model relates to a dental photopolymerization device, especially a dental photopolymerization device that improves curing effect, increases application range and is convenient to use.

Press, currently used for the treatment of discordant teeth in clinical dentistry, the defective part will be treated by filling (commonly known as filling), and the filling material includes silver powder, composite resin or ceramic materials, among which Silver powder has aesthetic problems due to its color, and there are concerns about mercury pollution. Therefore, at present, silver powder is not used as a filling material for teeth in the industry. Ceramic materials have the advantages of high physical strength and good adhesion, but the price is relatively high. In view of the concerns or problems derived from the aforementioned silver powder and ceramic materials, composite resins are mostly used as the main tooth filling materials at present.

The existing composite resin used for tooth filling contains a photoinitators/photocuring agent. After the existing composite resin is matched with a light source of a specific wavelength, a photopolymerization reaction is generated to cause the existing composite resin to undergo a curing reaction, so as to fill or seal the tooth. The parts of the defect that use the light source include halogen lamps, xenon lamps (plasma lamps), argon ion laser lamps and light-emitting diode (Light-emitting diode) lamps, among which halogen lamps are used. When the lamp is used, a filter needs to be set to generate the light source (blue light) required for photocuring. It is easy to generate high temperature during use and needs to be equipped with a cooling fan, and has problems such as short service life. Brightness, but complex structure and high price; although argon ion lamps can provide a stable light source, the energy ratio of input and output is too low, which does not meet the cost of use; LED lamps have low voltage and low cost Therefore, most of the existing dental photopolymerization devices use light-emitting diode lamps as light sources.

Further, although the existing dental photopolymerization device can use the light-emitting diode lamp to perform the photocuring reaction on the composite resin, but the light-emitting diode is not provided with a resonant cavity, so that the light system emitted by the light-emitting diode lamp 50 is as shown in FIG. 8 . It has a large divergence angle, that is, the light of the light-emitting diode lamp 50 will present a wide range of illumination on the object, which makes the energy of the light-emitting diode lamp 50 unable to concentrate, and secondly, it cannot accurately Light is irradiated on the position of the tooth 60 filled with the composite resin 70. Therefore, during the operation of the light-curing reaction through the light emitting diode lamp 50, when the tooth 60 filled with the composite resin 70 is irradiated as shown in FIG. The energy of the light emitted by the polar body lamp 50 is low, and the entire composite resin 70 cannot be irradiated for photocuring reaction. Only the composite resin 70 located on the outside can be photocured. Therefore, the light emitting diode lamp 50 is used as a light source. In the process of filling the composite resin 70, due to poor penetration, only a small amount of filling and multiple irradiations can be performed, which is relatively time-consuming and inconvenient to use, and the multiple filling and irradiation methods will also It affects the curing effect of the composite resin 70 and further affects the treatment effect of the teeth 60 .

Furthermore, there are quite a few types of composite resins 70 currently used as dental filling materials, including TPO (2,4,6-trimethylbenzoyl-diphenylosphine oxide), BAPO (Bisacylphosphine oxide), BP (Benzophenone), CQ (Camphorquinone), PQ(9,10-Phenanthrenequinone), PPD(1-pheneyl-1,2propanedione), TMBOPF(9-(2,4,6-trimethylbenzoyl)-9-oxytho-9-phosphafuluorene), TOPF(9-(p- toluyl)-9-oxytho-9-phosphafuluorene), BTMGe(Benzoyltrimethylgermane), DBDEGe(Dibenzoyldiethylgermane), IVO(Ivocerin-dibenzoyl germanium) and P3C-SB((7-ethoxy-4-methylcumarin-3-yl)phenyliodo-nium ) and other chemical materials, and the above-mentioned chemical materials absorb light in different wavelength ranges. Therefore, users often need to select or purchase a light source with a wavelength corresponding to the chemical material according to the method of using different chemical materials. After irradiation, the The composite resin undergoes a photopolymerization reaction. When the composite resin 70 used does not correspond to the light source, the composite resin 70 cannot be cured or the curing is incomplete, which in turn affects the treatment effect of the teeth 60. According to different composite resins Purchasing or using corresponding light sources (ie, needing to purchase multiple dental photopolymerization devices) will also cause usage costs and burdens to users. Therefore, the existing dental photopolymerization devices need to be improved.
