aplying k-means clustring technique on physical and mechanical properties of various pmma/silica bone cements

Various mixtures of bone cement having different quantities of solid phase (pmma, bpo, baso4), liquid phase (mma, n, n-dimethyl toluidine, hydroquinone) and nano-silica filler are prepared. the mixtures are injected into 2.5 ml plastic syringes after mixing for 30 sec. the syringes are then set in an oven for 24 hrs at 37 ° c. during polymerization, maximum polymerization temperatures are recorded using a thermovision camera the cured samples are analyzed by tga/dtg, and compressive and impact strengths are also obtained. all the results are anlysed by k-means clustring technique and it is found that the samples which are categorized according to their characteristics are devided into two groups of with filler and without filler.
