Biomaterials research programmes
Glass-ceramics for medicine and dentistry
Glass ceramics have great potential due to their toughness. Recent research at Sheffield has been focussed on overcomming solubility and biocompatibility problems that have limited their use as biomaterials.
Glass-ionomer cements (GICs) for bone repair
GIC bone cements are tough and easy to use, but, if used incorrectly, ions released during setting can result in neurotoxicity, and prevent bone growth. Researchers at Sheffield have been developing new GIC's with improved biocompatibility for bone repair.
Nano-features and nano-particles in restorative dentistry
Two technologies are currently under investigation, nano-fibre coatings to encourage linear cellular growth and mineral nano-particles in a colloidal suspension to interact with the damaged tooth.
High impact acrylics
Poly Methyl Methacrylate (PMMA) has been the standard material for making dentures since WW2, it has good aesthetics and ease of manufacture, but poor strength. Research is focussed on improving the service life while retaining ease of manufacture.
Optical properties of restorations
Analysis of the optical properties of ceramics to enable the prediction of light transmission and reflection from composite ceramic restorations.
