All groups were subjected to mechanical testing (flexural strength, impact strength, and hardness), water sorption and solubility tests, a tooth bonding test, microbiological assessment, and accuracy of fit measurements. The performance of sample groups was\u00a0referred to ISO 20795\u20101 and ISO\/TS 19736. The data was analyzed using one\u2010way ANOVA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Samples manufactured using FDM performed within ISO specifications for mechanical testing, water sorption, and solubility tests. However, the FDM group failed to achieve the ISO requirements for the tooth bonding test. FDM samples presented a rough surface finish which could ultimately encourage an undesirable high level of microbial adhesion. For accuracy of fit, FDM samples showed a lower degree of accuracy than existing materials.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Although FDM samples were a cost\u2010effective option and were able to be quickly manufactured in a reproducible manner, the results demonstrated that current recommended testing regimes for conventionally manufactured denture\u2010based polymers are not directly applicable to additive\u2010manufactured denture base polymers. Therefore, new standards should be developed to ensure the correct implementation of additive manufacturing techniques within denture\u2010based fabrication workflow.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cre2.880","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T07:00:26Z","timestamp":1716793226000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Assessing the suitability of fused deposition modeling to produce acrylic removable denture bases"],"prefix":"10.1002","volume":"10","author":[{"given":"Khalid K.","family":"Alanazi","sequence":"first","affiliation":[{"name":"School of Clinical Dentistry University of Sheffield Sheffield UK"},{"name":"Conservative Dental Science Department, College of Dentistry Prince Sattam Bin Abdulaziz University  Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duncan","family":"Wood","sequence":"additional","affiliation":[{"name":"School of Clinical Dentistry University of Sheffield Sheffield UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanna","family":"Shepherd","sequence":"additional","affiliation":[{"name":"School of Clinical Dentistry University of Sheffield Sheffield UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher W.","family":"Stokes","sequence":"additional","affiliation":[{"name":"School of Clinical Dentistry University of Sheffield Sheffield UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2674-664X","authenticated-orcid":false,"given":"Ilida Ortega","family":"Asencio","sequence":"additional","affiliation":[{"name":"School of Clinical Dentistry University of Sheffield Sheffield UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,5,27]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1108\/13552549610732034"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2019.03.010"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/jopr.12926"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3913(05)80330-0"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.sdentj.2009.12.006"},{"key":"e_1_2_10_7_1","volume-title":"Phillips'\u00a0science of dental materials","author":"Anusavice K.J.","year":"2012"},{"issue":"6","key":"e_1_2_10_8_1","first-page":"1450","article-title":"An evaluation on effect of surface treatment and mechanical modifications on shear bond strength between acrylic denture teeth and heat cure acrylic denture base resin","volume":"6","author":"Bhochhibhoya A.","year":"2016","journal-title":"EC Dental Science"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1108\/AA-06-2013-055"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0109-5641(97)80038-3"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3913(90)90051-D"},{"issue":"1","key":"e_1_2_10_12_1","article-title":"Study of the mechanical properties of photo\u2010cured epoxy resin fabricated by stereolithography process","volume":"35","author":"Chantarapanich N.","year":"2013","journal-title":"Songklanakarin Journal of Science & Technology"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compositesb.2017.02.045"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2842.2007.01779.x"},{"key":"e_1_2_10_15_1","volume-title":"Dental materials: Properties and manipulation","author":"Craig R.
