Comparative study of thermo-mechanical and thermogravimetric characterization of hybrid dental restorative composite materials

Abstract

The purpose of the study is to create resin-based micro-nano particulates-filled dental restorative composite materials and investigate the influence of variable nano-hydroxyapatite filler concentration on their thermo-mechanical and thermogravimetric properties. Two series were created by combining silane treated nano-hydroxyapatite filler particles (wt.% of 0, 2, 4, 6, and 8) with foreign ceramic particles (alumina and titanium oxide). Each series consists of five compositions. For each dental composition, the amount of foreign ceramics (20 wt.%) remained constant. The dental composite samples were polymerized for 30 s on each side using a blue LED light. Thermo-mechanical and thermogravimetric analysis was performed at various temperatures range. At preliminary temperatures (30–40°C), the hybrid nano-hydroxyapatite-TiO2 dental composite filled with 8 wt.% nano-hydroxyapatite exhibited storage modulus (about 90 MPa) whereas nano-hydroxyapatite-Al2O3 dental composite filled with 8 wt.% nano-hydroxyapatite exhibited storage modulus (about 260 MPa). Themal stability of nano-hydroxyapatite-Al2O3 and nano-hydroxyapatite-TiO2 dental composite was 99.90% and 99.82% at 90°C, respectively. The glass phase, glass transition phase, and rubbery phase were observed at various temperatures. From the results, it revealed that Al2O3-nano-hydroxyapatite filled dental composite was observed significant than TiO2–nano-hydroxyapatite filled dental composite.

Biomaterials for dental composite applications: A comprehensive review of physical, chemical, mechanical, thermal, tribological, and biological properties

“…Highly cross‐linked and light cross‐linked chain show the strong and weak stiffness between the polymer and ceramic particulates. Yadav and Meena 1,7 investigated marble dust powder, titanium oxide, alumina, and hydroxyapatite as fillers in dental composites. The range of temperature for DMA analysis and TGA analysis was 30–200°C and 30–330°C, respectively.…”
