Abstract
Current research is carried out for newly developed of Bio-CPNC biomaterial nanocomposite for dentistry applications. The developed Bio-CPNC is invented of clay-based polymer CPNC and palm-tree micro-fibers, where CPNC is composed by nanotechnology of HDPE and MMT nanoclay. The research contains the methodology of design, processing, testing and characterization mainly focusing on mechanical and fracture properties, microstructure morphology and testing of thermal effect changes due to surrounding temperature changes. The necessity for finding new biomaterials and new techniques for dental materials for restoration and orthodontics with high biocompatibility with human bones and tissue are the aim for developing this natural bio-nanocomposites to be instead of using ceramics and metals like titanium. The new developed bio-CPNC dental material have special mechanical, thermal and fracture properties to resist the effects of occlusal loads of mastication with sustainability without expecting bad effects with orofacial esthetics and normal lingual ability because it is green. It can be applied for different types of orthodontics like crowns, bridges and dental implants. The study included processing, design, testing and characterization of different properties. The testing included detailed fundamental experimental work for investigation of the changes of mechanical and fracture properties based on fracture mechanics science. The results and comparison are promising where they are showing large enhancement of the mechanical, fracture and thermal properties of Bio-CPNC in comparison to the polymer material which encourage the researchers, dentists, and dental-companies for extra research to stabilize these natural green Bio-CPNC nanocomposite for dental applications with reducing the cost where all materials components are available locally in comparison to use of conventional ceramics materials or expensive zirconia composites.
