Flexural strength and elastic modulus evaluation of structures made by conventional PMMA and PMMA reinforced with graphene
Abstract. – OBJECTIVE: The aim of this study
was to compare both the elastic modulus (EM)
and the flexural strength (FS) of two materials
used in dental prosthesis, namely polymethylmethacrylate (PMMA) and polymethylmethacrylate reinforced with graphene (G-PMMA).
MATERIALS AND METHODS: Twenty rectangular samples were manufactured by a milling machine and divided into two groups (n=
10/group): Group 1, PMMA; Group 2, G-PMMA.
The specimens were subjected to a three-point
bending test conducted in the elastic range to
