Dental lab light curing unit is an oral equipment for repairing teeth. Curing light for teeth is related to the rapid curing of dental repair resin material under the action of radiation energy by using the principle of light radiation.
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 of dental lab light curing unit is generally the same, respectively: light guide rod, light curable shield, LED lamp, electronic controller, battery and power supply.
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.
The dental curing light makes use of a light source with high intensity, a fluorescent bulb containing plasma to cure the resin-based composite, and is able to cure resin composite material within just 3 seconds. Over exposure to blue light cure without protection measurements may increase ocular inflammation and eye dryness. So safety measures should be used when the dentists use dental light curing unit in the operation or treatment.
Dental curing light can make use of the light source with high intensity, namely a fluorescent bulb containing plasma, to cure the resin matrix composite material, which is claimed to be able to cure the resin composite material in 3 seconds. Usually, when a trigger or button is pressed, the denture curing unit for sale stays on until the timer expires. When the dental curing light for sale is on, place it directly on the tooth containing the material until it is cured.
The dental curing light delivers ultraviolet (UV) light for photopolymerization in the operation or treatment. Studies have shown that exposure to UV radiation may cause damage to your skin, especially if you're exposed for a long time. It can lead to premature wrinkles, age spots, and even skin cancer. Therefore safety measures should be used when dentists use light curing units in dentistry in the operation or treatment.
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, curing light for teeth duration, and check whether the dental lab light curing unit 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 curing light wavelength and illumination time are different. Therefore, the corresponding wavelength, light intensity and illumination time of dental lab light curing unit need to be selected according to the operation instructions provided by the dental lab light curing unit manufacturer.
The effect on the photocurable material itself is minimal, but the heat generation of the dental lab light curing unit is too high and can irritate the pulp and soft tissue.
Curable light of dental lab light curing unit has very little attenuation, but we still recommend to test the light intensity of dental light curing units 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.
