“…To reinforce the properties of PMMA materials, a variety of filler particles have been investigated, including ceramics and metals ( Table 7 ). It is obvious from these studies that the addition of particles resulted in no biocompatibility issues and improved various properties of the PMMA, including the mechanical properties [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ], thermal conductivity [ 23 , 24 , 31 , 254 , 255 ], dimensional stability [ 256 ], and antimicrobial activity [ 257 , 258 , 259 , 260 , 261 , 262 , 263 , 264 , 265 , 266 ], and also reduced the solubility and water sorption [ 267 , 268 ]. The beneficial outcomes resulting from the use of nanoparticles are achieved due to their characteristic features, such as their high surface area and better distribution [ 34 , 269 ].…”
