Biomaterials

Current research in biomaterials encompasses physical, chemical and biological aspects of ceramic, metal, polymer and composite materials. Recent studies have investigated the strengthening mechanisms of dental ceramics and the development of new ceramic materials, the metallurgy and structure-property relationships for high-palladium alloys, the synthesis and characterization of polymeric materials for use in composite resins and glass ionomer cements, the esthetic characteristics of restorative and natural dental materials, the formulation of direct dental composite restorative materials based on optimum clinical performance, and the interactions of fibroblasts and epithelial cells with dental materials. Studies originating in the Biomedical Engineering Center have evaluated a copolymer formulation of bone cement for orthopedic implants. Research techniques employed include analytical and descriptive spectrometry, analytical electron microscopy, cell culturing, human visual evaluation, mechanical testing, rheology, thermal analysis (including calorimetry and thermomechanical analysis), and x-ray diffractometry.
