One can classify them based on many criteria, for example crystal structure (arrangement of atoms and bonds between them), or properties, or use. For most mineral reinforced dental composites, the primary interphasial linkage between the polymer matrix and the filler phase is by chemical bond formation, mediated by a dual functional organosilane, termed a silane coupling agent. Janak Sapkota is currently a research scientist at the Insitute of Polymer Processing, Montanuniversitaet Leoben (MUL), Austria. PMFs in implantology This increasing interest is attributed to not only the excellent surfaces of PMs and PMFs but also their desired mechanical and biological properties, low production cost, and ease in processing, allowing them to be tailored for a wide range of applications.
