Some Properties of 3D Printed Acrylic Resin Modified by Antifungal Vitis Vinifera Oil

Objective: The aim of the study was to study the consequences of different ratio of Vitis vinifera oil on the surface hardness, surface roughness and color change of 3D printed resin material. Material and Methods: 80 samples have been intended according to ADA specification 40 samples for hardness and roughness test and 40 samples for color change test, these two groups subdivided into four groups based on Vitis vinifera oil concentration 1%, 2%, 3% and control group without adding oil (0%). For each group, 10 specimens were prepared from 3D printer acrylic resin denture base, hardness was tested by shore D tester, Roughness test was done by TR 200 portable tester and color change test by spectrophotometer. Results: The control group recorded the maximum mean value for hardness and 3% Vitis vinifera recorded the lowest value, while for roughness and color test the minimum value recorded by control and 3% Vitis vinifera oil showed the maximum value for them, for all test the differences between control and 1% were not significant, but there were significant differences with 2% and 3%. Conclusion: The addition of 1% Vitis vinifera oil (antifungal oil) showed no adverse effect in hardness, roughness and color change value of 3D printer acrylic resin in comparison to control group.
