Stress Testing of 3D Printed VarseoSmile Crown Plus Resin
Abstract
Objective: To measure the flexural strength and flexural modulus of VarseoSmile Crown Plus Resin to evaluate suitability of the material as a permanent full-coverage dental restoration. Methods and Materials: A Formlabs 3D printer was used to fabricate 30 bars of VarseoSmile Crown Plus Resin sized 15 x 4 x 2 mm. Samples were then subjected to a three-point flexural test and the resulting stress-strain values were used to calculate flexural strength and flexural modulus. These values were compared to published values of other similar CAD/CAM milled materials and to ISO 6872:2015 to determine indications for clinical use. Results: The mean flexural strength of the 3D printed samples was measured at 106.67MPa and the mean flexural modulus was 5,376.08 MPa. Conclusions: The 3D printed samples had lower flexural strength compared to IPS Empress CAD, but greater strength when compared to Vitablocs Mark II. No difference was noted between the 3D printed samples and published values for Paradigm C in terms of flexural strength. The mean flexural modulus of the 3D printed samples was found to be significantly higher than reported by the manufacturer1 however and lower compared to IPS Empress CAD, Paradigm C, and Vitablocs Mark II.
