In our study, we aimed to design and manufacture subperiosteal dental implants with a minimum volume to facilitate surgical maneuvers and metal coverage by mucosa while ensuring maximal long-term implant strength and functionality. With cone-beam CT-scan data obtained from an edentulous patient, a maxilla and mandible recreation were created, and subperiosteal implants were designed and analyzed with FEA (250 MPa infinite-life limit stress). We redesigned them until they stood the infinite-life limit loads mentioned above. Then, they were manufactured with Ti6Al4V alloy and laser-powder bed fusion technology. All implants withstood mechanical tests (450 N static and 150 N loads for five-million cycle 150 N fatigue tests) with no failures. The first design resulted in maxillary and mandibular implant failures. Through the redesign process, the implant volume was reduced, and the number and placement of bone fixation screws were optimized while maintaining resistance to chewing. Once manufactured, these new implants withstood the loads mentioned above without failure. Our subperiosteal dental implants are an option for edentulous patients with severe maxilla and mandibular bone resorption. Manufactured with Ti6Al4V alloy and laser-powder bed fusion technology, they withstood the above-mentioned mechanical tests without failure.<\/jats:p>","DOI":"10.3390\/ma18030622","type":"journal-article","created":{"date-parts":[[2025,1,29]],"date-time":"2025-01-29T10:36:28Z","timestamp":1738146988000},"page":"622","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["New Subperiosteal Dental Implant Design with Finite Element Analysis and Mechanical Validation: A Design Validation Study"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4909-5886","authenticated-orcid":false,"given":"Vicente","family":"Vanaclocha","sequence":"first","affiliation":[{"name":"Department of Surgery, Medical School, University of Valencia, 46010 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"Atienza","sequence":"additional","affiliation":[{"name":"Instituto de Biomec\u00e1nica (IBV), Universitat Polit\u00e8cnica de Valencia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amparo","family":"Vanaclocha","sequence":"additional","affiliation":[{"name":"Instituto de Biomec\u00e1nica (IBV), Universitat Polit\u00e8cnica de Valencia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s","family":"Pe\u00f1uelas","sequence":"additional","affiliation":[{"name":"Instituto de Biomec\u00e1nica (IBV), Universitat Polit\u00e8cnica de Valencia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"G\u00f3mez-Herrero","sequence":"additional","affiliation":[{"name":"Instituto de Biomec\u00e1nica (IBV), Universitat Polit\u00e8cnica de Valencia, 46022 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francisco","family":"P\u00e9rez-Carri\u00f3","sequence":"additional","affiliation":[{"name":"Fresmedical Custom Digital Health, 03750 Pedreguer, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-3536-4084","authenticated-orcid":false,"given":"Jos\u00e9 Antonio","family":"Diego-Leyda","sequence":"additional","affiliation":[{"name":"Fresmedical Custom Digital Health, 03750 Pedreguer, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7816-3617","authenticated-orcid":false,"given":"Nieves","family":"S\u00e1iz-Sapena","sequence":"additional","affiliation":[{"name":"Hospital General Universitario de Valencia, 46014 Valencia, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leyre","family":"Vanaclocha","sequence":"additional","affiliation":[{"name":"Medius Klinik, Ostfildern-Ruit Klinik f\u00fcr Urologie, 73760 Ostfildern, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100","DOI":"10.3390\/prosthesis2020011","article-title":"Titanium alloys for dental implants: A review","volume":"2","author":"Nicholson","year":"2020","journal-title":"Prosthesis"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"e8135","DOI":"10.1002\/ccr3.8135","article-title":"Additively custom-made 3D-printed subperiosteal implants for the rehabilitation of the severely atrophic maxilla (a case report)","volume":"11","author":"Arshad","year":"2023","journal-title":"Clin.
