Advances in facial reconstructive surgery have been associated with less morbidity and more predictable results. In this paper, \u201cconventional\u201d genioplasty and genioplasty by means of virtual surgical planning (VSP), CAD-CAM cutting guides, and patient custom-made plates are compared. Methods: A descriptive observational study was designed and implemented, and 43 patients were treated, differentiating two groups according to the technique: 18 patients were treated by conventional surgery, and 25 patients were treated through virtual surgical planning (VSP), CAD-CAM cutting guides, STL models, and titanium patient-specific plates. Results: The operation time ranged from 35 to 107 min. The mean operative time in the conventional group was 60.06 + 3.74 min.; in the custom treatment group it was 42.24 + 1.29 min (p &lt; 0.001). The difference between planned and obtained chin changes in cases of advancement or retrusion was not statistically significant (p = 0.125; p = 0.216). In cases of chin rotation due to asymmetry, guided and personalized surgery was superior to conventional surgery (p &lt; 0.01). The mean hospital stay was equal in both groups. A decrease in surgical complications was observed in the group undergoing VSP and customized treatment. Conclusions: Multi-stage implementation of VSP with CAD-CAM cutting guides, STL models, and patient-specific plates increased the accuracy of the genioplasty surgery, particularly in cases of chin asymmetry, reducing operation time and potential complications.<\/jats:p>","DOI":"10.3390\/jpm13121702","type":"journal-article","created":{"date-parts":[[2023,12,12]],"date-time":"2023-12-12T11:30:14Z","timestamp":1702380614000},"page":"1702","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Guided Genioplasty: Comparison between Conventional Technique and Customized Guided Surgery"],"prefix":"10.3390","volume":"13","author":[{"given":"Ra\u00fal","family":"Ant\u00fanez-Conde Hidalgo","sequence":"first","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Luis","family":"Silva Canal","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9869-9240","authenticated-orcid":false,"given":"Carlos","family":"Navarro Cu\u00e9llar","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital General Universitario Gregorio Mara\u00f1\u00f3n, 28007 Madrid, Spain"},{"name":"Surgery Department, Universidad Complutense de Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Celia","family":"S\u00e1nchez Gallego-Albertos","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Arias Gallo","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ignacio","family":"Navarro Cu\u00e9llar","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital General Universitario Gregorio Mara\u00f1\u00f3n, 28007 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"L\u00f3pez Davis","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gast\u00f3n","family":"Demaria Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N\u00e9stor","family":"Naranjo Aspas","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Zamorano Le\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Public Health and Maternal and Child Health, Faculty of Medicine, Universidad Complutense de Madrid, 28040 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuel","family":"Chamorro Pons","sequence":"additional","affiliation":[{"name":"Maxillofacial Surgery Department, Hospital Universitario Ruber Juan Bravo, 28006 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,12,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1016\/j.cxom.2015.10.008","article-title":"Genioplasty","volume":"24","author":"Ferretti","year":"2016","journal-title":"Atlas Oral Maxillofac.
