Evaluation of Mechanical Properties of Zirconia Restorative Dental Materials Reinforced with Goat (Capra hircus) Bone

A significant issue in dental health care services is the wear and fracture of restorative dental materials. This study investigated the properties of dental restorative materials made of resin-based zirconia composite reinforced with goat (Capra hircus) bone. The bone was calcined at three different temperatures: 750oC, 850oC, and 950oC. The bone's percentage content ranged from 0% to 20% for each calcination temperature, resulting in thirteen samples that were examined for wear rate, hardness, impact, tensile strength and microstructure. The results show that it is possible to create dental restorative samples with 15% to 20% Capra hircus bone at a calcination temperature of 850 oC. The bone and teeth have similar chemical compositions, making the bone a good raw material for the creation of dental restorative materials.
