Eighteen consecutive patients were included, and preoperative virtual simulation surgery was performed using digital data. Segmental bone defects showed deviation of the mandible due to displacement of the condyle and segments, unnatural length of the mandibular body, or poorer intermaxillary relationship compared to the marginal bone defect caused by previous operations. These mandibular disharmonies could be simulated, and virtual surgery was performed on a computer with adjustment of displaced mandibular segments, length of the mandibular body, and dental arch with digital bone augmentation. TiMesh was manually pre-bent using a 3D printing model, and PCBM from the iliac crest was grafted with TiMesh. The short-term clinical results were good; reconstruction of the alveolar crest was prosthetically desirable; and minor complications were observed. In conclusion, virtual reconstruction is crucial for treating complex deviated mandibles. Accurate condylar and dental arch positions with an optimum mandibular length are important for prosthetically satisfactory mandibular reconstruction.<\/jats:p>","DOI":"10.3390\/jcm12031122","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T01:36:59Z","timestamp":1675215419000},"page":"1122","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Towards Optimum Mandibular Reconstruction for Dental Occlusal Rehabilitation: From Preoperative Virtual Surgery to Autogenous Particulate Cancellous Bone and Marrow Graft with Custom-Made Titanium Mesh\u2014A Retrospective Study"],"prefix":"10.3390","volume":"12","author":[{"given":"Kei","family":"Onodera","sequence":"first","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery, Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Dental Medicine, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4642-8611","authenticated-orcid":false,"given":"Ikuya","family":"Miyamoto","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery, Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Dental Medicine, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isao","family":"Hoshi","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery, Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Dental Medicine, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9858-7262","authenticated-orcid":false,"given":"Shinsuke","family":"Kawamata","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery, Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Dental Medicine, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noriaki","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Radiology, Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Dental Medicine, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuko","family":"Shimazaki","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics and Oral Implantology, School of Dentistry, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hisatomo","family":"Kondo","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics and Oral Implantology, School of Dentistry, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Yamada","sequence":"additional","affiliation":[{"name":"Division of Oral and Maxillofacial Surgery, Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Dental Medicine, Iwate Medical University, 19-1 Uchimaru, Morioka 020-8505, Iwate, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"394","DOI":"10.1016\/j.oraloncology.2008.05.017","article-title":"Current concepts in management of oral cancer--surgery","volume":"45","author":"Shah","year":"2009","journal-title":"Oral Oncol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1200","DOI":"10.1016\/S0278-2391(97)90165-8","article-title":"A comparison of vascularized and nonvascularized bone grafts for reconstruction of mandibular continuity defects","volume":"55","author":"Pogrel","year":"1997","journal-title":"J.
