The average mouth opening distance of an adult male patient is 30mm1. This limited range, coupled with the posterior placement of many restorations, makes it nearly impossible to position a traditional curing light with an oversized head or angled light guide. This typically forces the operator to tilt their light to a 45-60 degree angle, making direct irradiation of light on the restoration in posterior teeth nearly impossible.
The 12mm aperture of the lens simultaneously allows for easy positioning and coverage of a larger surface area, saving time and effort. With the VALO Grand® curing light, the patient only needs to open his/her mouth a comfortable 5 degree angle to allow access for the VALO Grand® lens.
The VALO Grand® curing light head height only measures 11 mm high, allowing it to fit over posterior teeth without causing patient discomfort. Because the wand-style body is designed without the addition of a light guide, it reaches all areas of the mouth without requiring you to overstretch a patient’s TMJ and soft tissues—a common problem that can occur with other lights. In addition, the VALO Grand® light’s larger footprint can cure the entire surface of a Class II posterior preparation in just one exposure.
