ABSTRACT

The use of nano-hydroxyapatite (n-HAp) has gained wide acceptance for nonremovable partial and complete dentures as one of the most biocompatible and bioactive materials in dentistry. This work is focused on the development of in-house, low cost, nonremovable partial and complete dentures, comprising of biocompatible polymer composites (reinforced with n-HAp particles). Initially, n-HAp particles were prepared from eggshells and blended with acrylonitrile-butadiene-styrene (ABS) granules for preparing fused deposition modelling (FDM) filament wire via a continuous extrusion process. Afterwards, dentures (partial/complete) have been prepared on a fused deposition modelling (FDM) setup by using this alternative filament wire. The final polymer composite dentures prepared to have better biocompatibility (resulting from the active participation of the n-HAp particles) and have properties of advanced/patented high cost material used in four-dimensional (4D) printing.
