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...
