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, VALO delivers optimally and consistently collimated power. With refined optics that create excellent light collimation across the nearly 10mm lens, VALO 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 7mm deep and best practices call for holding the tip of the curing light 2mm from the preparation surface.1 With a superior beam profile, VALO 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. VALO’s multiple LEDs and specialized optics produce evenly distributed energy to deliver consistent results, regardless of the restoration type, size, or location.
VALO uses a custom, multiwavelength light-emitting diode (LED) for producing a high-intensity light at 395–480nm. This LED pack produces true broad-spectrum light, which provides uniform curing across the restoration with two significant peak wavelengths, utilizing two shades of blue and violet required for lower-level initiators. This means that VALO is capable of polymerizing all light-cured dental materials—including camphorquinone and the entire range of proprietary photoinitiators.
As the options for light-cured materials keep expanding, the composition of the materials becomes more and more varied. Aside from camphorquinone, many manufacturers have turned to other photoinitiators particularly for esthetic composites. Photoinitiators such as Lucerin and PPD require low-wavelength light for complete polymerization. With VALO’s reliable and proven performance, you can be certain you’ll get a quality cure, regardless of the material.
The distance the average adult-male mouth opens is 30mm 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.
VALO’s 5° head angle and large 9.6mm glass lens allow for easy positioning of the light and more surface area to be cured at once, saving time and effort. Because VALO’s 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, VALO’s large 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, VALO 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: 1400 mW/cm2
- Xtra Power: 3200 mW/cm2
Each of these 3 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 MARC system,4 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 VALO consistently delivers more energy in less time. Even with the inevitable variation in curing results among testers, VALO delivered more energy more consistently.
