Over the past decade, dental implants and dentures have become a reliable method of restoring missing teeth. Materials used have been extensively researched and their physical and chemical properties are well understood. Today, implant materials have been improved towards being biocompatible, corrosion and break resistant. All combined with excitingly realistic aesthetics. To ensure long-term aesthetics, color stability testing against daylight has always been critical.
Color Stability Testing of Dental Materials and Artificial Gums
In the 1980’s, the original test procedure was written around a SUNTEST equipped with a water immersion unit. It was published as European standard EN 27491. The international succession version is ISO 7491.
The current SUNTEST CPS+ provides daylight at an elevated level (150 klux) and controls the immersion water temperature at 37°C. This is a quite realistic simulation of human oral conditions. The typical test duration is 24 or 48 hours, which corresponds to several years of dental materials and artificial gums in use. Use of the larger SUNTEST XLS+ offers even twice the test capacity.
