<p><a href="https://www.dentalchairpart.com/dental-led-curing-light" rel="noopener noreferrer" target="_blank"><strong>Dental led curing light</strong></a> (dental photosensitive resin curing machine) is a machine used to cure photosensitive resin materials when dentists help patients repair their teeth. Dental led curing light is composed of light source part and control circuit. Scope of product: curing resin materials for the restoration of teeth in the middle cavity department.</p><p><br></p><p>Compared with the halogen lamp, the LED used in the light curing machine has a much smaller calorific value, and the light is almost blue light, so it is cold light.</p><p><br></p><p>The light intensity of <a href="https://www.dentalchairpart.com/dental-led-curing-light" rel="noopener noreferrer" target="_blank">Dental led curing light</a> is not as high as possible. Expert research shows that the mechanical strength of the light-cured photosensitive resin is related to the number of cross-linked long-chain macromolecules in the resin. The greater the number, the better the mechanical properties. If too high light intensity is used, the molecules in the resin have no time to flow and have been cured, which will generate a large number of short-chain molecules, causing the resin to generate higher internal shrinkage stress and reduced mechanical properties. At the same time, the joint between the resin and the cavity Easy to produce cracks. The recommended method is to use weak light guidance. The initial low light intensity is conducive to the movement of molecules in the resin and the formation of long-chain macromolecules. Later, it is quickly cured with high light intensity to achieve a better curing effect. Extensive testing has shown that the light intensity of the <a href="https://www.dentalchairpart.com/dental-led-curing-light" rel="noopener noreferrer" target="_blank">Dental led curing light </a>is more than 200 mW/cm 2 for the ultra-bright LED type and more than 500 mW/cm 2 for the high-power LED, which can achieve a curing effect superior to that of the ordinary halogen lamp curing machine.</p>
