Dental ceramics have an excellent ability to reproduce natural teeth appearance, but once the substrate has an altered coloration, it is necessary to mask this intercurrence, considering the characteristics of the ceramic and cement selected. This article aims to present a clinical case of rehabilitation with ceramic laminates to mask a darkened central incisor by planning a more opaque porcelain structure under a translucent contact lens. A female patient sought dental care complaining of dissatisfaction with smile aesthetics. It was clinically identified the presence of a Class IV darkened restoration in composite resin in element 11. In treatment planning harmony in the shape and color of elements 11 and 21 was aimed at through lithium disilicate lenses. An opaque intermediate structure was used to cover the darkening in tooth 11. The double molding technique was performed to obtain the working model. Prior to cementing, the surfaces were treated. In ceramics, conditioning with 10% hydrofluoric acid and 37% phosphoric acid, silane application and universal adhesive; in dental substrate, conditioning with 37% phosphoric acid and application of universal adhesive were performed. In laminates definitive cementation Allcem Venner cement was chosen. Patient reported satisfaction with treatment final aesthetics. Thus, cementation technique of a translucent laminate over an opaque facet is a good option for masking substrates with darkened coloration.

Due to growing demand for metal-free dental restorations, dental ceramics, especially dental zirconia, represent an increasing share of the dental implants market. They may offer mechanical performances of the same range as titanium ones. However, their use is still restricted by a lack of confidence in their durability and, in particular, in their ability to resist hydrothermal ageing. In the present study, the ageing kinetics of commercial zirconia dental implants are characterized by X-ray diffraction after accelerated ageing in an autoclave at different temperatures, enabling their extrapolation to body temperature. Measurements of the fracture loads show no effect of hydrothermal ageing even after ageing treatments simulated a 90-year implantation.
