The Impact of Adding Carbon Nanotubes to 3D Printed Denture Base Resin on Denture, Diametral Compression, and Tensile Strength.

Denture performance and quality depend on 3D-printed denture base polymers' mechanical characteristics, including tensile strength and diametral compression strength, when determining material suitability. This study evaluates the performance of a resin used in denture base 3D printing, focusing on its adaptation properties, diametral compression, and tensile strength with the addition of carbon nanotubes (CNTs). Ninety specimens were printed: thirty denture bases for denture adaptation test, thirty diskshaped specimens for diametral compression test and thirty dumbull-shape specimens for tensile strength test. Each test has three groups (n = 10). Every test had unreinforced 3D-printed denture base resin as the control group; the other groups were reinforced with 0.5% and 0.7% by wt. CNTs. Exocad software was used to assess denture adaptation, and a universal testing machine was used to assess diametral compression and tensile strength. There was a substantial change in the denture adaption, diametral compression, and tensile strength of the 3D-printed denture base resin when CNTs were added. The mean values of tensile strength and diametral compression increased with 0.5% and 0.7% of CNTs, respectively, as denture adaptation increased. CNTs can enhance the mechanical and adaptability qualities of the base resin used in 3Dprinted dentures. [ABSTRACT FROM AUTHOR]
