The Ivoclar Vivadent Bluephase G4 curing light features an automated assistance system called Polyvision technology that detects if the handpiece is moved during the exposure process and if the restoration no longer can be cured reliably.
If the handpiece moves, the light emits a vibration alert to inform the operator of the error and, if necessary, automatically extends the exposure time by 10%. If the handpiece moves too much—for example, if the light guide slips out of the oral cavity—the light automatically switches off so the curing procedure can be repeated correctly.
According to Ivoclar Vivadent, the Bluephase G4 offers easy handling, discreet assistance, reliable curing results, and satisfied patients. It offers a light output of 1200 mW/cm2, polywave LED technology in a broadband spectrum of 385 to 515 nm, and a 10-mm wide light guide with a homogenous beam profile for high-quality results in a short time frame, the company reports.
