Objectives: The aim of this Short Communication was to present a workflow for the superimposition of intraoral scan (IOS), cone-beam computed tomography (CBCT), and extraoral face scan (EOS) creating a 3D virtual dental patient. Material and Methods: As a proof-of-principle, full arch IOS, preoperative…

OBJECTIVE: To identify nasal width changes occurring after Le Fort I osteotomy and to compare prospectively the effect of three surgical techniques for controlling postoperative nasal width. METHODS: In the study, 79 patients (22 male and 57 female, mean…
Date: March 2015. Source: JIMD Reports 2015, Springer. Abstract: There is a pattern of progressive facial dysmorphology in mucopolysaccharidosis type I (MPS I). Advances in 3D facial imaging have facilitated the development of tools, including dysmorphometrics, to objectively and precisely detect these facial phenotypes. Therefore, we investigated the application of dysmorphometrics as a noninvasive therapy-monitoring…
Date: February 2015. Source: Orthodontics & Craniofacial Research, 18(1):21-6. Objectives: Several reports have demonstrated a relationship between second to fourth digit ratio (2D:4D) and facial shape, suggesting that prenatal sex hormones play a role in the development of the craniofacial complex. Using 3D surface imaging and geometric morphometrics, we test the hypothesis that decreased digit…
Date: February 2015. Source: The European Journal of Orthodontics. Objectives: Assess facial asymmetry in subjects with unilateral cleft lip (UCL), unilateral cleft lip and alveolus (UCLA), and unilateral cleft lip, alveolus, and palate (UCLP), and to evaluate which area of the face is most asymmetrical. Methods: Standardized three-dimensional facial images of 58 patients (9 UCL,…
Date: February 2015. Source: The Cleft Palate-Craniofacial Journal. Abstract: In severe syndromic craniosynostosis, distraction osteogenesis (DO) provides superior segmental advancement and allows progressive clinical monitoring to ensure that adequate skeletal expansion is achieved. We report two cases of Crouzon syndrome involving a 3-year-old boy and a 4-year-old girl, who were both treated with monobloc Le…
Date: January 2015 Source: International Journal of Oral and Maxillofacial Surgery, 44(1):83-9. Abstract: Orthognathic surgery aims to improve both the function and facial appearance of the patient. Translation of the maxillomandibular complex for correction of malocclusion is always followed by changes to the covering soft tissues, especially the nose and lips. The purpose of this study…
Date: December 2014 Source: British Journal of Oral Maxillofacial Surgery, 52(10):922-7. Abstract: Volume changes in facial morphology can be assessed using the 3dMDface® stereo-optical 3-dimensional scanner, which uses visible light and has a short scanning time. Its reliability and validity have not to our knowledge been investigated for the assessment of facial swelling. Our aim…
Date: December 2014. Source: Journal of the Formosan Medical Association. Background/Purpose. Orthognathic surgery alters the position of maxilla and mandible, and consequently changes the nasal shape. The nasal change remains a concern to Asian patients. The aim of this study was to measure the nasal changes using a novel three-dimensional photographic imaging method. Methods. A…
Date: December 2014 Source: Journal of Healthcare Engineering, Volume 5, Number 4. Abstract. The purpose of this pilot study was to assess whether orthodontic treatment planning is reproducible when carried out using digital records compared with clinical examinations or using standard records. The study also assessed patients’ opinion of face-to-face consultations and potential use of…
