| description | Additive manufacturing technology can be used for denture bases and also denture teeth. Therefore, the mechanical properties of 3D-printed resin denture teeth should be evaluated.
The purpose of this in vitro study was to compare the wear resistance of 3D-printed denture tooth resin with that of conventionally prefabricated denture teeth.
Eighty substrate specimens were prepared with 5 kinds of resin denture teeth: 3D-printed denture tooth resin (DENTCA denture tooth resin; DENTCA, Inc), Artic 6 (Kulzer GmbH), Preference (Candulor AG), Premium 6 (Kulzer GmbH), and Surpass (GC Corp). The 3D-printed denture tooth specimens were made of methacrylate-based photopolymerized resin by stereolithography 3D printing. Antagonistic surfaces were made from zirconia by milling and from cobalt-chromium (Co-Cr) alloy by 3D printing and casting. The specimens were loaded at 49 N for 30 000 cycles under thermocycling conditions in a mastication simulator. Wear resistance was measured by calculating the volume of substance lost. Wear surface characteristics were observed by using a scanning electron microscope (SEM). Two-way ANOVA was used to analyze the data (α=.05).
The influence of the resin denture teeth and the type of antagonist were both statistically significant. The wear volume loss of the 3D-printed denture tooth resin was higher than that of Artic 6 and Preference when opposing the zirconia and the metal antagonists (P |

The influence of the resin denture teeth and the type of antagonist were both statistically significant. The wear volume loss of the 3D-printed denture tooth resin was higher than that of Artic 6 and Preference when opposing the zirconia and the metal antagonists (P<.05). The 3D-printed denture tooth resin did not show a significant difference from Premium 6 with the zirconia and the metal antagonists or Surpass with the zirconia antagonist. From the SEM images, the specimens of the 3D-printed denture tooth resin showed a relatively smooth surface with the zirconia antagonist and exhibited cracks when opposed by the metal antagonist.
The results suggest that 3D-printing by using resin materials provides adequate wear resistance for denture tooth use.</description><identifier>ISSN: 0022-3913</identifier><identifier>EISSN: 1097-6841</identifier><identifier>DOI: 10.1016/j.prosdent.2019.09.004</identifier><language>eng</language><publisher>Elsevier Inc</publisher><subject>Dentistry</subject><ispartof>The Journal of prosthetic dentistry, 2020-09, Vol.124 (3), p.387-394</ispartof><rights>2019 Editorial Council for the Journal of Prosthetic Dentistry</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c411t-1034b38e524a313d37926838327c2bd179379513e6ed71099f757bddad3688bd3</citedby><cites>FETCH-LOGICAL-c411t-1034b38e524a313d37926838327c2bd179379513e6ed71099f757bddad3688bd3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://dx.doi.org/10.1016/j.prosdent.2019.09.004$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,780,784,3550,27924,27925,45995</link.rule.ids></links><search><creatorcontrib>Cha, Hyun-Suk</creatorcontrib><creatorcontrib>Park, Ji-Man</creatorcontrib><creatorcontrib>Kim, Tae-Hyung</creatorcontrib><creatorcontrib>Lee, Joo-Hee</creatorcontrib><title>Wear resistance of 3D-printed denture tooth resin opposing zirconia and metal antagonists</title><title>The Journal of prosthetic dentistry</title><description>Additive manufacturing technology can be used for denture bases and also denture teeth.
