Dental-implant supported restorations were installed in a dry mandible. Magnetic resonance scans were acquired on a 3-Tesla MRI system. Artifact suppression (SEMAC + VAT) was applied with different intensity modes (weak, moderate, strong). Artifacts assessment was performed by measuring the mandible volume increase in MRI images prior (reference dataset) and after installation of dental implant-supported prosthesis. Image quality was assessed by two examiners using a five-point scale. Inter-examiner concordance and correlation analysis was performed with Cronbach\u2019s alpha and Spearman\u2019s test with a significance level at p = 0.05. Mandible volume increased by 60.23% when no artifact suppression method was used. By applying SEMAC + VAT, the volume increase ranged from 17.13% (strong mode) to 32.77% (weak mode). Visualization of mandibular bone was positively correlated with SEMAC intensity degree. SEMAC + VAT reduced MRI artifacts caused by dental-implant supported restorations. A stronger suppression mode improved visualization of mandibular bone in detriment of the scanning time.<\/jats:p>","DOI":"10.3390\/jcm12031117","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T01:36:59Z","timestamp":1675215419000},"page":"1117","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["SEMAC + VAT for Suppression of Artifacts Induced by Dental-Implant-Supported Restorations in Magnetic Resonance Imaging"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3637-3928","authenticated-orcid":false,"given":"Lauren","family":"Bohner","sequence":"first","affiliation":[{"name":"Department of Cranio-Maxillofacial Surgery, University Hospital Muenster, 48149 Muenster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcel","family":"Hanisch","sequence":"additional","affiliation":[{"name":"Department of Cranio-Maxillofacial Surgery, University Hospital Muenster, 48149 Muenster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hian","family":"Parize","sequence":"additional","affiliation":[{"name":"Department of Cranio-Maxillofacial Surgery, University Hospital Muenster, 48149 Muenster, Germany"},{"name":"Department of Prosthodontics, School of Dentistry, University of S\u00e3o Paulo, S\u00e3o Paulo 05508-220, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Newton","family":"Sesma","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics, School of Dentistry, University of S\u00e3o Paulo, S\u00e3o Paulo 05508-220, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Kleinheinz","sequence":"additional","affiliation":[{"name":"Department of Cranio-Maxillofacial Surgery, University Hospital Muenster, 48149 Muenster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norbert","family":"Meier","sequence":"additional","affiliation":[{"name":"University Hospital Muenster, 48149 Muenster, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"529","DOI":"10.11607\/jomi.7076","article-title":"Fully Digitally Guided Implant Surgery Based on Magnetic Resonance Imaging","volume":"34","author":"Mercado","year":"2019","journal-title":"Int.
