A three-dimensional FE model of the maxillary and mandibular cortical bone, cancellous bone, and gingiva was constructed based on edentulous cone-beam-computed tomography data. Dental computer-aided design software was used to design the denture base and artificial teeth to produce a complete denture. Mesh convergence was performed to derive the optimal mesh size, and validation was conducted through comparison with mechanical test results. The mandible was rotated step-by-step to induce movements similar to actual mastication. Results showed that there was less than a 6% difference between the mechanical test and the alveolar bone-complete denture. It opened 10\u00b0 as set in the first stage, confirming that the mouth closed 7\u00b0 in the second stage. Occlusal contact occurred between the upper and lower artificial teeth as the mouth closed the remaining angle of 3\u00b0 in the third stage while activating the masseter muscle. These results indicate that the FE model and masticatory loading conditions developed in this study can be applied to analyze biomechanical effects according to the wearing of dentures with various design elements applied.<\/jats:p>","DOI":"10.3390\/bioengineering11040336","type":"journal-article","created":{"date-parts":[[2024,3,29]],"date-time":"2024-03-29T06:33:16Z","timestamp":1711693996000},"page":"336","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Finite Element Analysis Study of Edentulous Model with Complete Denture to Simulate Masticatory Movement"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-5519-8345","authenticated-orcid":false,"given":"Jeong-Hyeon","family":"Lee","sequence":"first","affiliation":[{"name":"Medical Device Research and Development Center, DENTIS Co., Ltd., Daegu 41065, Republic of Korea"},{"name":"Department of Biomedical Engineering, Inje University, Gimhae-si 50834, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6702-1960","authenticated-orcid":false,"given":"Jeong-Hee","family":"Seo","sequence":"additional","affiliation":[{"name":"Medical Device Research and Development Center, DENTIS Co., Ltd., Daegu 41065, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin-Wook","family":"Park","sequence":"additional","affiliation":[{"name":"Medical Device Research and Development Center, DENTIS Co., Ltd., Daegu 41065, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Won-Gi","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Dental Technology, Daegu Health College, Daegu 41453, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4793-9125","authenticated-orcid":false,"given":"Tae-Gon","family":"Jung","sequence":"additional","affiliation":[{"name":"Medical Device Development Center, Osong Medical Innovation Foundation, Cheongju-si 28160, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Jae","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Inje University, Gimhae-si 50834, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"296","DOI":"10.4047\/jkap.2019.57.3.296","article-title":"Fabrication of complete dentures by conventional method and CAD\/CAM milling: A case report","volume":"57","author":"Jung","year":"2019","journal-title":"J.
