The MRI data and virtual dental models derived from either optical model scans or intraoral scans were imported to a virtual implant planning software (coDiagnostiX, Dental Wings, Montreal, Canada). Virtual prosthetic planning and implant planning were performed regarding the hard and soft tissue anatomy. A drill guide was designed on the virtual dental model using computer\u2010aided design (CAD) and manufactured in\u2010house, using a 3D printer (Eden 260V, Stratasys, Eden Prairie, MN, USA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The MRI displayed all relevant anatomical structures for dental implant planning such as cortical and cancellous bone, floor of the nasal and maxillary sinus, inferior alveolar nerve and neighboring teeth. The manual alignment of virtual dental models with the MRI was possible using anatomical landmarks. Dental implant planning, CAD\/CAM of a drill guide and fully guided implant placement were successfully performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Guided implant surgery is feasible with MRI without ionizing radiation. Further studies will have to be conducted to study the accuracy of the presented protocol and compare it to the current workflow of guided surgery using CBCT.<\/jats:p><\/jats:sec>","DOI":"10.1111\/clr.13592","type":"journal-article","created":{"date-parts":[[2020,2,27]],"date-time":"2020-02-27T15:03:02Z","timestamp":1582815782000},"page":"575-583","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Virtual implant planning and fully guided implant surgery using magnetic resonance imaging\u2014Proof of principle"],"prefix":"10.1111","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1288-8452","authenticated-orcid":false,"given":"Tabea","family":"Fl\u00fcgge","sequence":"first","affiliation":[{"name":"Charit\u00e9 \u2013 Universit\u00e4tsmedizin Berlin Corporate Member of Freie Universit\u00e4t Berlin Humboldt\u2010Universit\u00e4t zu Berlin and Berlin Institute of Health Department of Oral and Maxillofacial Surgery Berlin Germany"},{"name":"Department of Oral and Maxillofacial Surgery Faculty of Medicine Translational Implantology Medical Center \u2013 University of Freiburg University of Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0526-5935","authenticated-orcid":false,"given":"Ute","family":"Ludwig","sequence":"additional","affiliation":[{"name":"Medical Physics Department of Radiology Faculty of Medicine Medical Center \u2013 University of Freiburg University of Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan\u2010Bernd","family":"H\u00f6vener","sequence":"additional","affiliation":[{"name":"Medical Physics Department of Radiology Faculty of Medicine Medical Center \u2013 University of Freiburg University of Freiburg Freiburg Germany"},{"name":"Section for Biomedical Imaging and MOIN CC Clinic for Radiology University Medical Center Schleswig\u2010Holstein Kiel Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7095-4190","authenticated-orcid":false,"given":"Ralf","family":"Kohal","sequence":"additional","affiliation":[{"name":"Department of Prosthetic Dentistry Faculty of Medicine Medical Center \u2013 University of Freiburg University of Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6736-1941","authenticated-orcid":false,"given":"Daniel","family":"Wismeijer","sequence":"additional","affiliation":[{"name":"Department of Oral Implantology Academisch Centrum Tandheelkunde Amsterdam (ACTA) Amsterdam Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katja","family":"Nelson","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery Faculty of Medicine Translational Implantology Medical Center \u2013 University of Freiburg University of Freiburg Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,3,12]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.11607\/jomi.2014suppl.g1.4"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/mrm.22828"},{"issue":"7","key":"e_1_2_9_4_1","first-page":"43","article-title":"Optimizing esthetics for implant restorations in the anterior maxilla: Anatomic and surgical considerations","volume":"19","author":"Buser D.","year":"2004","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"issue":"11","key":"e_1_2_9_5_1","first-page":"ZC105","article-title":"Imaging of temporomandibular joint: Approach by direct volume rendering","volume":"8","author":"Cuccia A.
