Abstract
Objectives: The objective of this research was to investigate how boron nitride powder addition in percentages of 1% weight and 1.5% weight, affected the thermal conductivity, transverse strength, and surface hardness of heat cured acrylic resin denture base material. Methods: Ninety specimens were made from heat-cured acrylic resin and then divided into three groups based on the tests: a control group, a reinforced poly methyl methacrylate group with 1% weight boron nitride particles, and a reinforced poly methyl methacrylate group with 1.5% weight boron nitride particles. They investigated into the thermal conductivity, transverse strength, and surface hardness tests. Results: This research showed that 1% and 1.5% weight boron nitride particles significantly increased thermal conductivity and surface hardness in comparison to the controlled group. There was a highly significant increase in transverse strength compared to the control group; at the concentration of 1% weight boron nitride particles. Conclusion: Boron nitride particles enhance the thermal conductivity, transverse strength, and surface hardness when added to heat cure acrylic resin denture base material.
