Abstract Objective The aim of this study was to evaluate the trueness 3D-printed dental inlays fabricated using different permanent resins and subjected distinct postcuring times. Materials methods A total 180 inlay specimens were divided into nine groups 20 each. first designed 3D design software (Ansys SpaceClaim) then transferred a printer. Using LCD technology, 60 from Senertek P-CrownV3 Ceramic (Senertek) resin, another VarseoSmile Crown Plus (Bego) resin final Saremco Print Crowntec (Crowntec) resin. Each these three equally sized subgroups ( n = 20) cured with 2,000, 4,000 6,000 flashes, respectively, Otoflash G171 device (NK Optik, Germany). Then, scanned digitised an intraoral digital scanner, their evaluated by superimposing measurements on reference calculating root mean squares (RMSs) overlap ratios (TORs). MANOVA used compare measurements, Tukey’s test utilised for post hoc analysis. Results Significant differences in observed among types p < 0.001). had lowest RMS (0.08 ± 0.018 mm) highest TOR (94.59 2.49%), indicating best trueness, while (0.114 0.017 (80.15 5.95%), reflecting trueness. time also significantly affected inlays. 6,000-flashes group (0.095 0.02 mm), 4000-flashes (89.81 0.5%). interaction between type significant 0.01), suggesting that improvements are material dependent. Conclusion Both influenced restorations. consistently exhibited superior demonstrated optimal varied material, but flashes generally provided favourable outcomes. These findings highlight importance selecting appropriate optimising parameters enhance inlays, potentially improving clinical fit longevity. Clinical relevance Appropriate selection adherence optimised protocols essential achieving clinically true restorations, ultimately adaptations applications.
