Dental deviceIvoclar Vivadent AG
With this device, patented Polyvision technology is applied to curing dental materials. The curing light automatically detects movement of the handpiece during the light-curing procedure. It alerts the user of the improper operation by vibrating and automatically extends the exposure time by 10 percent, if necessary. If the movement may prevent the material from curing properly, the light will automatically interrupt the exposure cycle so that it can be repeated. Bluephase G4 comes with active anti-glare protection to prevent the light from being activated in open space.
