Coated dental articles and related methods of manufacture
Provided are dental articles, and methods of making articles, having an aesthetic inorganic coating based on zirconia at least partially stabilized with yttrium oxide, calcium oxide, cerium oxide, or magnesium oxide. Stabilized zirconia coatings were found to provide a smooth, low friction surface having high abrasion resistance. These coatings are particularly applicable to orthodontic appliances. While virgin stabilized zirconia coatings can often have an undesirable color cast, it was discovered that this color cast can be substantially eliminated by heat treating the coated appliance in an oxygenated environment. The combination of depositing a stabilized zirconia coating and subsequently heat treating to decolorize the coating provides a surprisingly robust, stable, low-friction coating that is also aesthetic.
