The invention relates to a polymerization and post-tempering device () for tempering, in particular post-tempering, dental restoration parts () made of polymerizable plastics. At least one light source () which emits light in the visible and/or ultraviolet wavelength range and a light chamber with a door () to the light chamber are provided. The door () comprises a window () with a window pane () which consists of at least two layers () whose layer facing the light chamber reflects at least 90%, in particular approximately 95%, of light, and whose layer facing away from the light chamber filters out UV light and/or blue light.

Polymerization and post-tempering device

The invention is directed to a light curing device, in particular for dental restoration materials, having a light source and a control device for the light curing device, which control device is capable of switching on the light source at different levels of power. The light curing device includes an actuation element which can be used to switch on the light curing device upon actuation by the user at a reduced dosage of light for pre-curing the dental restoration material. The control device in particular signalizes the reduced dosage.

Light curing device for dental restoration materials and method of curing dental restoration materials

A hand-held light curing apparatus is used with a housing (), a light source (), in particular at least one LED, which is connected to a control unit (), an energy source () and at least one energy storage unit in the form of at least one double layer capacitor (). It is provided that the light source () is fed simultaneously by the energy source () which is formed as a local energy source such as an accumulator and the double layer capacitor ().
