The light-curing materials are complex resins (composites) that are familiar in everyday Dentistry. High biocompatibility leads to the absolute respect of natural oral environment, while their mechanic attributes are the nearest in those of natural teeth. Composites are not only the Dentist's favorite material but also suitable for laboratorial manufacture of permanent restorations. The layering materials of these restorations are clearly light-curing laboratorial complex resins for restorations with or without metal, or other material, framework. The high content of this materials in organic micro-iridescent reinforcing factors provides most optimal behavior from abrasion, discoloration and surface polish. The elements of fuorescence, the ceramic elements and the numerous of shades they can cover play an important role in the natural optical behavior of restorations. These materials are ideal for implant supported hyperdentures with exceptional attributes and considerably decreased weight.
