Effect of repair and thermal cycling on the flexural strength of denture base materials fabricated from different methods

Objective: The aim of this study was to evaluate the flexural strength denture base materials produced by different methods after repair and effect thermal aging.
 Materials Methods: A total 120 specimens were fabricated conventional, CAD/CAM milled, 3D-printed for in vitro study. Specimens divided into four groups; non-repaired groups (N), repaired (R), non-repaired-aged (N-aged), repaired-aged (R-aged) groups. In N groups, stored water bath 24 h before test. N-aged samples subjected aging 5000 cycles, then tested. For R with auto-polymerized acrylic resin storage R-aged resin, aged performed a three-point loading test using universal testing machine. Data analyzed Wilcoxon Kruskal-Wallis tests.
 Results: When compared each other, difference between all found be statistically significant (p
