Fifteen patients in need of any type of treatment whose execution considered a pre- and post-CBCT assessment consented and were enrolled. CBCTs were taken with the following settings: 90 kV, 8 mA, field of view (FOV) 140 by 100 mm (height and diameter), Voxel size 0.25 mm (high resolution). The pre-CBCT was executed in the maximum mandibular opening (MO), while the post-CBCT was in the maximum intercuspation (MI). A thermoplastic stent with radiopaque fiducial markers (steel ball bearings) was fabricated for each patient. Measurements were made using radiographic markers between contralateral canines and contralateral first molars and between ipsilateral canines and first molars on both sides. Paired t-tests were performed to evaluate the difference between open and closed positions on these four measurements. In the MO position were registered a significative tightening of the mandible at the canine (\u22120.49 mm, SD 0.54 mm; p &lt; 0.001) and molar points (\u22120.81 mm, SD 0.63 mm; p &lt; 0.001) and a significative shortening of the mandible on the right (\u22120.84 mm, SD 0.80 mm; p &lt; 0.001) and left sides (\u22120.87 mm, SD 0.49 mm; p &lt; 0.001). Within the study limitations, mandibular flexure determined a significant shortening and tightening between maximum intercuspation to maximum opening positions. Mandibular dimensional changes should be considered in light of other patient factors in the treatment planning of implant positioning and long-span complete arch implant-supported fixed prostheses in order to avoid technical complications.<\/jats:p>","DOI":"10.3390\/jcm12124149","type":"journal-article","created":{"date-parts":[[2023,6,21]],"date-time":"2023-06-21T02:01:33Z","timestamp":1687312893000},"page":"4149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Mandibular Flexure and Its Significance: An In Vivo Cone Beam-Computed Tomography Proof-of-Concept Study"],"prefix":"10.3390","volume":"12","author":[{"given":"Jimmy","family":"Londono","sequence":"first","affiliation":[{"name":"Ronald Goldstein Center for Esthetic and Implant Dentistry, Department of Restorative Sciences, Dental College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2738-5778","authenticated-orcid":false,"given":"Todd","family":"Schoenbaum","sequence":"additional","affiliation":[{"name":"Department of Restorative Sciences, Dental College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alma","family":"Varilla Ortiz","sequence":"additional","affiliation":[{"name":"Independent Researcher, Puebla 72000, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guillermo","family":"Franco-Romero","sequence":"additional","affiliation":[{"name":"Stomatology and Oral Rehabilitation Residency Program, Benemerita Universidad Autonoma de Puebla, Puebla 72000, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vanessa","family":"Villalobos","sequence":"additional","affiliation":[{"name":"Department of Restorative Sciences, Dental College of Georgia, Augusta, GA 30912, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2442-1091","authenticated-orcid":false,"given":"Paolo","family":"Carosi","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Translational Medicine, School of Dentistry, University of Tor Vergata, 00133 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1661-7529","authenticated-orcid":false,"given":"Eitan","family":"Mijiritsky","sequence":"additional","affiliation":[{"name":"The Maurice and Gabriela Goldschleger School of Dental Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"},{"name":"Head and Neck Maxillofacial Surgery, Tel Aviv Sourasky Medical Center, Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6139001, Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3052-8186","authenticated-orcid":false,"given":"Alessandro","family":"Pozzi","sequence":"additional","affiliation":[{"name":"Ronald Goldstein Center for Esthetic and Implant Dentistry, Department of Restorative Sciences, Dental College of Georgia, Augusta, GA 30912, USA"},{"name":"Department of Clinical Sciences and Translational Medicine, School of Dentistry, University of Tor Vergata, 00133 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1015","DOI":"10.1016\/j.joms.2006.03.009","article-title":"Biomechanics of the Mandible Part I: Measurement of Mandibular Functional Deformation Using Custom-Fabricated Displacement Transducers","volume":"64","author":"Helenius","year":"2006","journal-title":"J.
