ABSTRACT
This in vitro study investigates the effect of different post-rinsing times and methods on trueness precision denture base resin manufactured through stereolithography.Ninety clear photopolymer specimens were fabricated divided into nine groups (n = 10) based rinsing methods. All rinsed with 99% isopropanol alcohol for 5, 10, 15 min using three methods-automated, ultrasonic cleaning, hand washing. The polymerized 30 at 40℃. For trueness, scanned intaglio surface each SLA was superimposed original standard tessellation language (STL) file best-fit alignment 10). precision, STL specimen group across 45). root mean square error (RMSE) measured, data analyzed statistically one-way ANOVA Tukey test (α < .05).The 10-min automated exhibited lowest RMSE. this significantly from 5-min hand-washed (P .05). those other .05), except 15-min groups. color map results indicated that method most uniform distribution adaptation.The optimal postprocessing achieving found to be 10 min, a time min.
