Surface studies on acrylic bone cement
Bettencourt, A; Calado, A; Amaral, J; Alfaia, A; Vale, FM; Monteiro, J; Montemor, MF; Ferreira, MGS; Castro, MPoly(methyl methacrylate) (PMMA) is used to fill the gap between the prosthesis and the surrounding bone in cemented arthroplasties. Biocompatibility problems related to bone cement application limit the clinical success of these cemented arthroplasties. Being the cement surface in close connection with the living bone, it is reasonable to assume that surface properties such as, surface composition and surface ...

The effect of ethanol on acrylic bone cement
Bettencourt, A; Calado, A; Amaral, J; Vale, FM; Rico, JMT; Monteiro, J; Montemor, MF; Ferreira, MGS; Castro, MProsthesis loosening is a major problem associated with the use of poly(methyl methacrylate) (PMMA) bone cement that may be related to a peri-implant vacuolisation commonly observed at bone-cement interface. Methyl methacrylate (MMA) monomer may be one of the cement components partly responsible for the mentioned vacuolisation due to a cytotoxic effect associated to this compound. Alcoholism has been related to...
The effect of ethanol on bone cement biocompatibility

The influence of vacuum mixing on methylmethacrylate liberation from acrylic ce...
Bettencourt, A; Calado, A; Amaral, J; Vale, FM; Rico, JMT; Monteiro, J; Castro, MPolymethylmethacrylate (PMMA) bone cement is a biomaterial used to anchor prostheses during joint replacement surgery. Residual methylmethacrylate monomer (MNA) may be related with the cytotoxic effect of PM MA. The aim of the present paper was to investigate the effect of two different cement mixing methods: hand stirring at atmospheric pressure and under partial vacuum (0.330 and 0.154 bar) on residual monome...
