Abstract

In this study, hydroxyaptite (HA) Ca10 (PO4)6(OH)2 nano size has been synthesized from waste materials (egg shell and fish bone ) and then mixed with resin composite in order to measure the mechanical properties and linear shrinkage of composite materials designed for dental restoration. The material was composed of visible light-curing monomer (composan LCM) as a matrix and hydroxyapatite (nano particles) as a reinforcing filler at different ratios (5-10-15wt%).The results show that the mechanical properties increases with added HA powder and up to 287Hv at the rate 15% of hydroxyapatite as well as the case for the compressive strength and the depth of cure to 130 Mpa and 2.65mm respectively, while the linear shrinkage decrease to 0.097mm at 15% hydroxyapatite.
