A series of simplified maxillary segment models varying in residual bone height (RBH) and bone quality were established. A 10\u2009mm standard implant combined with two types of maxillary sinus augmentation methods was applied with the RBH, which was less than 10\u2009mm in the maxilla. The maximal equivalent von Mises (EQV) stress in residual bone was evaluated. Bone quality had an enormous impact on the stress magnitude of supporting bone. Applying sinus augmentation combined with grafts was suitable for stress distribution, and high-stiffness graft performed better than low-stiffness one. For 7\u2009mm and 5\u2009mm atrophic maxilla, nongrafted maxillary sinus augmentation was feasible in D3 bone. Poor bone quality was a negative factor for the implant in the region of atrophic posterior maxilla, which could be improved by grafts. Meanwhile, the choice of maxillary sinus augmentation approaches should be determined by the RBH and quality.<\/jats:p>","DOI":"10.1155\/2020\/8419319","type":"journal-article","created":{"date-parts":[[2020,10,5]],"date-time":"2020-10-05T18:20:13Z","timestamp":1601922013000},"page":"1-8","source":"Crossref","is-referenced-by-count":4,"title":["Biomechanical Analysis of Grafted and Nongrafted Maxillary Sinus Augmentation in the Atrophic Posterior Maxilla with Three-Dimensional Finite Element Method"],"prefix":"10.1155","volume":"2020","author":[{"given":"Xuan","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, China"},{"name":"Department of Oral and Maxillofacial Surgery, Shandong Provincial Hospital Affiliated to Shandong University, Jinan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianqi","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enli","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiyuan","family":"Gong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongzhou","family":"Shen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8896-3869","authenticated-orcid":true,"given":"Haiwei","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1331-379X","authenticated-orcid":true,"given":"Dongsheng","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2004.01117.x"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.prosdent.2004.10.001"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.4047\/jap.2011.3.1.10"},{"issue":"6","key":"4","first-page":"1594","article-title":"Biomechanical comparison of a single short and wide implant with monocortical or bicortical engagement in the atrophic posterior maxilla and a long implant in the augmented sinus","volume":"27","author":"S.
