AN APPARATUS FOR THE PHOTO-POLYMERISATION OF COMPOSITE MATERIALS, IN PARTICULAR FOR DENTAL APPLICATIONS

摘要

An apparatus for the photo-polymerisation of composite materials, in particular for dental applications, comprising emitter means (10) for generating at least one electromagnetic radiation (20) and irradiating a material to be polymerised, and a control unit (30) for regulating the power irradiated by the emitter means (10), in such a way that said irradiated power has a profile comprising a first segment (2) of polymerisation that is substantially growing or constant over time, and a second segment (3) of thermal control, subsequent in time and contiguous to the first, and having at least one portion (3a) decreasing over time with finite derivative.
