is completely cured by light alone use of light polymerizable resin materials makes it possible to fabricate denture base material 18 in segments as opposed to fabricating the entire base at one time as when heat polymerized polymethylmethacrylate pmma materials are used it is preferable that the denture base be fabricated of materials having some type of reinforcement material dispersed therein including but not limited to fillers fibers or a combination thereof to increase the strength and reliability of the components base material 18 is easy to handle and bonds well to the substructure beneath it and to the denture teeth placed into it using a light polymerized resin material reduces the polymerization shrinkage of the suprastructure due to the ability of the technician to place and polymerize the material in segments during the fabrication thereof each segment compensates for the shrinkage of the previous segment addition of light polymerized low shrinkage resins to attach the substructure to the already polymerized suprastructure results in little or no prosthesis distortion prior to placement in the patient 39 s mouth in order to strongly bond the denture teeth to the denture base material the materials may be mechanically or chemically etched or abraded to provide good adhesive surfaces the denture base material may include a low viscosity component that is able to wet the treated denture tooth surface resulting in optimal micromechanical retention improved bonding between the denture teeth.
