Light curing machine is an oral equipment for repairing teeth. It is related to the rapid curing of dental repair resin material under the action of radiation energy by using the principle of light radiation.
LED light curing machine is the use of the principle of light radiation, dental repair resin materials under the action of radiation energy rapid curing and involved.It can emit a strong blue light, so that the photofixation resin in a short period of time quickly and effectively polymerized curing.
Light curing machine can be divided into LED light curing machine and halogen light curing machine.
Now the market is commonly used in LED light curing machine, because the wavelength of light emitted by LED, concentrated in the 430 ~ 480nm, is the sensitive wavelength of light curing resin, because there is no other color light, so more than 90% of the energy is converted to pure blue light energy, almost no excess heat generation
LED light curable machine has a variety of appearance, but the structure is generally the same, respectively: light guide rod, light curable shield, LED lamp, electronic controller, battery and power supply
This situation shows that the material curing is not sufficient, need to pay attention to whether to operate in accordance with the instructions of the material; Note the maximum filling thickness and required light intensity, light duration, and check whether the light intensity of the light curing lamp is appropriate.
How long is the binder best illuminated?What is the exposure time of the double curing material used to bond the prosthesis?
Different materials have different triggering systems, so the required excitation wavelength and illumination time are different. Therefore, the corresponding wavelength, light intensity and illumination time need to be selected according to the operation instructions provided by the manufacturer.
The effect on the photocurable material itself is minimal, but the heat generation is too high and can irritate the pulp and soft tissue.
Curable light has very little attenuation, but we still recommend to test the light intensity before use every day to ensure the accuracy of the output light intensity.At the same time, the charging base of the light curing lamp is equipped with light intensity tester, which is very convenient to measure light intensity.
