وصف الابستركت (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.

الوصف الكامل (Full 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.
