ABSTRACT Apparatus and method for providing light curing of prostheses and other medical (including dental) object materials, the object being prefabricated of a material which is hardened, or polymerized when exposed to visible light. An array of light sources is provided relative to a rotatable platform on which the object is placed, each light source providing a substantially collimated light beam and directed to optimally intercept the rotating denture. There are preferably four such light sources, each having a visible light bandpass characteristic and directed at an angle within 25°-45° relative the platform surface, the light beams being directed at the platform surface in overlapping fashion so as to provide continuous incident light on the denture during each cycle of rotation.
