Various materials such as zirconia and polyetheretherketone (PEEK) are developed for subtractive manufacturing. As for additive manufacturing, dental professionals have begun to use selective laser melting (SLM) techniques for fabricating metallic RPD frameworks. This report demonstrates a case rehabilitated with a maxillary telescopic crown-retained combining PEEK and zirconia material denture and a mandibular Kennedy Class I RPD fabricated with SLM techniques. First, a conventional impression was performed and the master cast was mounted with a centric relation record. Digital models were obtained using tabletop scanners and then the telescopic primary zirconia crowns were designed and milled. After transferring the intraoral distribution of primary crowns using pick-up impression, secondary PEEK crowns and framework were designed, milled, and veneered with composite resin. Mandibular framework was designed and constructed using SLM technique with Ti-6Al-4V. Definitive prostheses for both jaws were finished and delivered. Delivered prostheses functioned well for a one-year period. The was patient satisfied with the improvements in chewing function and esthetics. Both substrative and additive manufacturing techniques are suitable for framework fabrication. Further investigation is needed for improving the mechanical performance and long-term prognosis of digitally made prostheses.<\/jats:p>","DOI":"10.3390\/ijerph19053021","type":"journal-article","created":{"date-parts":[[2022,3,6]],"date-time":"2022-03-06T20:38:16Z","timestamp":1646599096000},"page":"3021","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Digitally Fabricated Dentures for Full Mouth Rehabilitation with Zirconia, Polyetheretherketone and Selective Laser Melted Ti-6Al-4V Material"],"prefix":"10.3390","volume":"19","author":[{"given":"Wei-Ting","family":"Lee","sequence":"first","affiliation":[{"name":"Division of Prosthodontics, Department of Stomatology, National Cheng Kung University Hospital, Tainan 704, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3942-2484","authenticated-orcid":false,"given":"Yung-Chung","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Prosthodontics, Department of Stomatology, National Cheng Kung University Hospital, Tainan 704, Taiwan"},{"name":"School of Dentistry & Institute of Oral Medicine, Medical College, National Chen Kung University, Tainan 704, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"316","DOI":"10.1016\/j.prosdent.2018.11.010","article-title":"Adaptation of removable partial denture frameworks fabricated by selective laser melting","volume":"122","author":"Chen","year":"2019","journal-title":"J.
