    Master of Science (Oral Health Sciences), 2022Background and objectives: With the advent of computer-aided design and computer-aided manufacturing, a novel technique for fabricating complete dentures has evolved. Digital complete denture fabrication can be accomplished by an additive or subtractive approach which minimal distortion during processing contributes to effective denture base adaption, which leads to good denture retention. The aim of this study was to compare the accuracy of milled and 3D-printed complete denture bases. Materials and Methods: The reference edentulous maxillary arch model was scanned to generate virtual denture bases using computer-aided manufacturing (CAD) software that exports as standard tessellation language (STL) files. Denture bases were constructed using a milling and printing technique called digital light processing (DLP) (10 specimens per technique). Denture bases' intaglio surfaces were scanned and superimposed on the reference model. The accuracy was quantified as root mean square error (RMSE) and evaluated statistically using independent T-test comparisons with a significance level of 0.05. Results: The measurement area was divided into three regions. Milled dentures were significantly more accurate than 3D-printed dentures in the overall intaglio area and primary bearing area of denture bases. Denture bases printed demonstrated significantly greater accuracy than milling dentures in the peripheral/posterior palatal seal area. Conclusion: According to the study's findings, milled dentures fit better in the overall and primary stress-bearing areas than 3D-printed dentures, while 3D-printed dentures appeared more accurate in the peripheral seal area.āļ§āļąāļ•āļ–āļļāļ›āļĢāļ°āļŠāļ‡āļ„āđŒ: āļāļēāļĢāļĻāļķāļāļĐāļēāļ™āļĩāđ‰āļ—āđāļēāđ€āļžāļ·āđˆāļ­āđ€āļžāļ·āđˆāļ­āđ€āļ›āļĢāļĩāļĒāļšāđ€āļ—āļĩāļĒāļšāļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡āļ‚āļ­āļ‡āļāļēāļ™āļŸāļąāļ™āđ€āļ—āļĩāļĒāļĄāļ—āļąāđ‰āļ‡āļ›āļēāļāļœāļĨāļīāļ•āļ”āđ‰āļ§āļĒāļ§āļīāļ˜āļĩāļāļēāļĢāļāļĨāļķāļ‡āđāļĨāļ°āļāļēāļĢāļžāļīāļĄāļžāđŒāļŠāļēāļĄāļĄāļīāļ•āļī āļ§āļąāļŠāļ”āļļāđāļĨāļ°āļ§āļīāļ˜āļĩāļāļēāļĢ: āļ™āđāļēāđāļšāļšāļˆāđāļēāļĨāļ­āļ‡āļ­āđ‰āļēāļ‡āļ­āļīāļ‡āļŠāļąāļ™āđ€āļŦāļ‡āļ·āļ­āļāđ„āļĢāđ‰āļŸāļąāļ™āļšāļ™āļĄāļēāđāļ›āļĨāļ‡āļ‚āđ‰āļ­āļĄāļđāļĨāļ”āļīāļˆāļīāļ—āļąāļĨāđ‚āļ”āļĒāļŠāđāļāļ™āļ”āđ‰āļ§āļĒāđ€āļ„āļĢāļ·āđˆāļ­āļ‡āđāļŠāđāļāļ™āļ™āļ­āļāļŠāđˆāļ­āļ‡āļ›āļēāļ āļāļĨāļļāđˆāļĄāļ•āļąāļ§āļ­āļĒāđˆāļēāļ‡āļ—āļąāđ‰āļ‡āļŦāļĄāļ” 20 āļŠāļīāđ‰āļ™ āđāļšāđˆāļ‡āļ­āļ­āļāđ€āļ›āđ‡āļ™ 2 āļāļĨāļļāđˆāļĄ āđ„āļ”āđ‰āđāļāđˆ āļœāļĨāļīāļ•āļ”āđ‰āļ§āļĒāļ§āļīāļ˜āļĩāļāļēāļĢāļāļĨāļķāļ‡ āđāļĨāļ°āļœāļĨāļīāļ•āļ”āđ‰āļ§āļĒāļāļēāļĢāļžāļīāļĄāļžāđŒāļŠāļēāļĄāļĄāļīāļ•āļīāļœāļĨāļīāļ•āļ•āļēāļĄāļ„āđāļēāđāļ™āļ°āļ™āđāļēāļ‚āļ­āļ‡āļœāļđāđ‰āļœāļĨāļīāļ• āļ§āļąāļ”āļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡āļ”āđ‰āļ§āļĒāđ‚āļ›āļĢāđāļāļĢāļĄāļŠāļēāļĄāļĄāļīāļ•āļīāđ‚āļ”āļĒāļāļēāļĢāļ‹āđ‰āļ­āļ™āļ—āļąāļšāđ€āļ­āļŠāļ—āļĩāđāļ­āļĨāđ„āļŸāļĨāđŒāļĢāļ°āļŦāļ§āđˆāļēāļ‡āļ”āđ‰āļēāļ™āđ€āļ™āļ·āđ‰āļ­āđ€āļĒāļ·āđˆāļ­āļ‚āļ­āļ‡āļŸāļąāļ™āđ€āļ—āļĩāļĒāļĄāđāļĨāļ°āđāļšāļšāļˆāđāļēāļĨāļ­āļ‡āļ­āđ‰āļēāļ‡āļ­āļīāļ‡ āđ‚āļ”āļĒāđāļšāđˆāļ‡āļšāļĢāļīāđ€āļ§āļ“āļ­āļ­āļāđ€āļ›āđ‡āļ™ 3 āļšāļĢāļīāđ€āļ§āļ“ 1. āļšāļĢāļīāđ€āļ§āļ“āļ—āļąāđˆāļ§āļ—āļąāđ‰āļ‡āļāļēāļ™āļŸāļąāļ™āļ›āļĨāļ­āļĄ 105 āļˆāļļāļ” 2. āļšāļĢāļīāđ€āļ§āļ“āļ‚āļ­āļšāđ‚āļ”āļĒāļĢāļ­āļšāđāļĨāļ°āļŠāđˆāļ§āļ™āļāļąāđ‰āļ™āļ—āđ‰āļēāļĒāđ€āļžāļ”āļēāļ™ 72 āļˆāļļāļ” āđāļĨāļ° 3. āļšāļĢāļīāđ€āļ§āļ“āļŠāđˆāļ§āļ™āļĢāļ­āļ‡āļĢāļąāļšāļ›āļāļĄāļ āļđāļĄāļī140 āļˆāļļāļ” āļ§āļīāđ€āļ„āļĢāļēāļ°āļŦāđŒāļ‚āđ‰āļ­āļĄāļđāļĨāļ—āļēāļ‡āļŠāļ–āļīāļ•āļīāļ”āđ‰āļ§āļĒāļŠāļ–āļīāļ•āļīāļ—āļ”āļŠāļ­āļšāļ—āļĩ āļœāļĨāļāļēāļĢāļ—āļ”āļĨāļ­āļ‡: āđƒāļ™āļšāļĢāļīāđ€āļ§āļ“āļ—āļąāđˆāļ§āļ—āļąāđ‰āļ‡āļāļēāļ™āļŸāļąāļ™āđ€āļ—āļĩāļĒāļĄāļāļēāļĢāļœāļĨāļīāļ•āļ”āđ‰āļ§āļĒāļ§āļīāļ˜āļĩāļāļēāļĢāļāļĨāļķāļ‡āđƒāļŦāđ‰āļ„āđˆāļēāļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡ 0.0964 āļ‹āļķāđˆāļ‡āļ”āļĩāļāļ§āđˆāļēāļ§āļīāļ˜āļĩāļāļēāļĢāļžāļīāļĄāļžāđŒāļŠāļēāļĄāļĄāļīāļ•āļīāđƒāļŦāđ‰āļ„āđˆāļēāļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡ 0.1219 āļ—āļĩāđˆāļĢāļ°āļ”āļąāļšāļ™āļąāļĒāļŠāđāļēāļ„āļąāļāļ—āļĩāđˆ p<0.001 āđƒāļ™āļšāļĢāļīāđ€āļ§āļ“āļ‚āļ­āļšāđ‚āļ”āļĒāļĢāļ­āļšāđāļĨāļ°āļŠāđˆāļ§āļ™āļāļąāđ‰āļ™āļ—āđ‰āļēāļĒāđ€āļžāļ”āļēāļ™āļ›āļēāļāļ„āđˆāļēāļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡āļ§āļīāļ˜āļĩāļāļēāļĢāļžāļīāļĄāļžāđŒāļŠāļēāļĄāļĄāļīāļ•āļīāđ„āļ”āđ‰āļ„āđˆāļēāļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡ 0.1635 āļ‹āļķāđˆāļ‡āļ”āļĩāļāļ§āđˆāļēāļ§āļīāļ˜āļĩāļāļēāļĢāļāļĨāļķāļ‡ 0.839 āļ—āļĩāđˆāļĢāļ°āļ”āļąāļšāļ™āļąāļĒāļŠāđāļēāļ„āļąāļāļ—āļĩāđˆ p=0.009 āđāļĨāļ°āļšāļĢāļīāđ€āļ§āļ“āļĢāļ­āļ‡āļĢāļąāļšāļ›āļāļĄāļ āļđāļĄāļīāļ„āđˆāļēāļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡āļ”āđ‰āļ§āļĒāļ§āļīāļ˜āļĩāļāļēāļĢāļāļĨāļķāļ‡ 0.0207 āļ”āļĩāļāļ§āđˆāļēāļāļēāļĢāļœāļĨāļīāļ•āļ”āđ‰āļ§āļĒāļ§āļīāļ˜āļĩāļžāļīāļĄāļžāđŒāļŠāļēāļĄāļĄāļīāļ•āļī0.0498 āļ—āļĩāđˆāļĢāļ°āļ”āļąāļšāļ™āļąāļĒāļŠāđāļēāļ„āļąāļāļ—āļĩāđˆ p<0.001 āļŠāļĢāļļāļ›āļœāļĨāļāļēāļĢāļ—āļ”āļĨāļ­āļ‡: āļāļēāļĢāļŠāļĢāđ‰āļēāļ‡āļāļēāļ™āļŸāļąāļ™āđ€āļ—āļĩāļĒāļĄāļ—āļąāđ‰āļ‡āļ›āļēāļāļšāļ™āļ§āļīāļ˜āļĩāļāļēāļĢāļāļĨāļķāļ‡āļĄāļĩāļ„āđˆāļēāļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡āļ—āļĩāđˆāļ”āļĩāļāļ§āđˆāļēāļāļēāļĢāļžāļīāļĄāļžāđŒāļŠāļēāļĄāļĄāļīāļ•āļīāđƒāļ™āļšāļĢāļīāđ€āļ§āļ“āļ—āļąāđˆāļ§āļ—āļąāđ‰āļ‡āļāļēāļ™āļŸāļąāļ™āđ€āļ—āļĩāļĒāļĄāđāļĨāļ°āļšāļĢāļīāđ€āļ§āļ“āļĢāļ­āļ‡āļĢāļąāļšāļ›āļāļĄāļ āļđāļĄāļī āđƒāļ™āļ‚āļ“āļ°āļ—āļĩāđˆāļšāļĢāļīāđ€āļ§āļ“āļ‚āļ­āļšāđ‚āļ”āļĒāļĢāļ­āļšāđāļĨāļ°āļŠāđˆāļ§āļ™āļāļąāđ‰āļ™āļ—āđ‰āļēāļĒāđ€āļžāļ”āļēāļ™āļ›āļēāļāļāļēāļĢāļžāļīāļĄāļžāđŒāļŠāļēāļĄāļĄāļīāļ•āļīāđƒāļŦāđ‰āļ„āļ§āļēāļĄāļ–āļđāļāļ•āđ‰āļ­āļ‡āļ—āļĩāđˆāļ”āļĩāļāļ§āđˆ
