  • Dental composite light curing system
    Patent number: 6602074
    Abstract: A process for preparing dental restorations includes the steps of applying a composite restorative material onto a prepared tooth followed by the application of light to the composite of intensity sufficient to penetrate the composite to initiate polymerization. Light application is then suspended for a period of time sufficient to allow for the relaxation of internal stresses created by the initial polymerization of the composite. Light is subsequently applied to the composite to complete polymerization. A curing light is utilized which includes variably-adjustable, multiple power and timing settings.

  • Stereolithographic curl reduction
    Patent number: 5772947
    Abstract: An improved stereolithography system for generating a three-dimensional object by creating a cross-sectional pattern of the object to formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, information defining the object being structurally specified to reduce curl, stress and distortion in the ultimately formed object, the successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process.
