Mechanical Properties of Denture-base Resins Processed by Conventional and 3D Printing Methods

Abstract

Limited research has been published evaluating the mechanical properties of new 3D-printed denture-base materials. Objective: The purpose of this study was to evaluate the mechanical properties (flexural strength, flexural modulus, nanoindentation hardness, nanoindentation modulus, and diametral tensile strength) of three new denture-base materials processed via 3D printing (Denture Base LP Resin1L, Form labs; Next Dent Denture 3D+, NextDent; Dentca Denture Base II, Whip mix) and compare them with a conventionally processed denture-base material (Lucitone 199, Dentsply Sirona). Methods: Flexural strength (FS) and flexural modulus (FM) were measured using a 3-point bend test with rectangular beams (n=12). Nanoindentation Hardness (NH) and nanoindentation modulus of elasticity (NM) were tested using nanoindentation with the fragmented specimens from the flexural strength test (n=6).
