50% Larger Lens
The VALO Grand curing light offers the same accessibility, durability, and power as any curing light in the VALO family, but is differentiated by a large, 12 mm lens. The VALO Grand light still has the same power output, but with a larger footprint, it is able to cure a larger area quickly and effectively.
Beam Collimation and Uniformity
The collimation of a curing light’s beam affects the amount of energy that reaches the restoration site. A beam that disperses will deliver less power than a beam that remains collimated; a dispersed beam can lead to undercured restorations and eventual failures. Unlike its competitors, the VALO Grand curing light delivers optimally and consistently collimated power. With refined optics that create excellent light collimation across a 12 mm lens, the VALO Grand light maintains intensity over a greater range of distances.
It is not easy to maintain a specific distance from the restoration, where the typical proximal box is approximately 7 mm deep and best practices call for holding the tip of the curing light 2 mm from the preparation surface.1 With a superior beam profile, the VALO Grand curing light ensures more energy is delivered to resin and significantly reduces the possibility that the practitioner will experience distance and offset issues while curing.
In addition to its collimation, a beam’s uniformity affects energy delivery across the restoration site. A beam with hot or cold spots yields inconsistent curing, which can compromise restorations and cause sensitivity. The VALO Grand light contains multiple LEDs and specialized optics produce evenly distributed energy to deliver consistent results, regardless of the restoration type, size, or location.
The distance the average adult-male mouth opens is 30 mm when working in vivo.2 This limited range, along with the posterior location of many restorations, makes properly positioning a traditional curing light with an oversized head and angled light guide almost impossible.
The VALO Grand curing light has a 5° head angle and large 12 mm glass lens to allow for easy positioning of the light and more surface area to be cured at once, saving time and effort. 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.
Complete Cure with Any Composite
When composite is exposed to light, its reaction depends on the composite’s hue, refractive properties, filler type, filler load, and translucency/opacity. Regardless of variations in composite, the VALO Grand curing light has the ability to provide a complete cure because of its power distribution and output of broad-spectrum light, which effectively penetrates layers of composite.
3 Powerful Curing Modes
- Standard Power: 1000 mW/cm2
- High Power Plus: 1600 mW/cm2
- Xtra Power: 3200 mW/cm2
Each of these three curing modes offers varying timing intervals to best meet the needs of the clinician and the procedure.
In a study,3 the energy delivered to a Class I preparation by 20 dentists with different curing lights was measured with the MARC4 system, the only device available that calculates a curing light’s actual power delivered in a truly simulated curing environment. It provides clinically relevant data to better manage the variables that determine the effective use of curing lights in clinical practice. Through this process, it has been repeatedly shown that the VALO curing light consistently delivers more energy in less time. Even with the inevitable variation in curing results among testers, the VALO light delivered more energy more consistently.
