Light hardening apparatus for effecting the light hardening of dental restoration pieces

Abstract

A light hardening apparatus for effecting the photopolymerization of a light hardenable dental restoration material is provided and includes a plurality of light sources supported on semi-conductor bases, which are mounted on a substrate. The light sources are arranged in at least two light source groups such that one group of light sources is disposed for irradiating a region of the dental restoration material and another group of light sources is arranged for irradiating a different region of the dental restoration material. The two groups of light sources are controllable to irradiate their respective associated regions of the dental restoration material independently of one another.
