Abstract: Incorporating Hexagonal Boron Nitride (HBN) and Boron Nitride Nanotubes (BNNTs) into Formlabs Dental Resin presents a strategic approach to engineering composite materials with enhanced mechanical properties. This study investigates the synergistic effects of HBN and BNNTs when integrated into the resin matrix. HBN, at a concentration of 1 wt.%, was uniformly dispersed within the dental resin, while BNNTs, dispersed in Dimethylformamide (DMF) at 0.1 wt.%, underwent thorough dispersion within the resin matrix. Subsequent compression testing was performed on three distinct composite formulations: pristine resin, HBN-modified resin, and BNNT-enhanced resin. Results revealed substantial enhancements in mechanical strength, with pristine resin exhibiting a strength of 12 MPa, HBN-modified resin achieving 22 MPa, and BNNT-enhanced resin demonstrating an impressive strength of 31 MPa. Scanning Electron Microscopy (SEM) analysis elucidated the morphological characteristics and interfacial interactions between HBN particles, BNNTs, and the dental polymer, highlighting their reinforcement mechanisms within the composite structure. These findings underscore the potential of HBN and BNNTs as effective reinforcing agents in dental resin composites, offering avenues for further optimization and development in composite material design.
