A preliminary study on the reactive suspension approach to create bioactive polymer nanocomposites for dental applications

Abstract

The modified chemical particle with appropriate combination agents possesses a lesser surface and the organic matrix gives more compatibility with the unprocessed matrix, is a typical strategy for limiting agglomeration problems. The limited time processing was the main sign of the chemical modification and particle purification. The production of nanoparticles directly inside the organic matrix is an alternate technique in situ approach. The present studies focused to make a new nanocomposites matrix with powder and liquid phase PMMA and hydroxyethyl methacrylate and it is processed by in-situ method to compose the hydroxyapatite nanoparticles of (Ca10(PO4)6(OH)2. Therefore reactive suspension approach was utilized in this study. During the in-situ process, the precursors like ammonium dihydrogen and calcium nitrate tetrahydrate are used. When the combinations of HA with the influence of the HEMA agent. These precursors and the agents composed the hybrid material with even dispersion. Due to maximum phase interrelations were achieved between the dead filler and polymer matrix base. HA is an inorganic phase that is osteogenic and osteoconductive, comparable to bone-based minerals. Similarly, it promotes polymer-based composites from bioactivity to enhance bone regeneration. The structure and morphology characteristics of PMMA, hydroxyethyl methacrylate and HA processed composites are examined in this work. The mechanical characteristics of the composites are measured in the combinational mode of compression and flexural. Then the bioactivity is investigated by submerging into the simulated bodily fluid (SBF). The mixing among the HA and polymer reduces the water sorption values significantly. After soaking in simulated bodily fluid, the surface of the HA generation was verified into the bioactivity of the processes composites.
