Date: September 2018. Source: Computational Statistics & Data Analysis, Volume 125, pp 57-69. Highlights: • A novel scale space technique for analyzing spherical data is proposed. • Distributions of normal vector directions computed from a 3dMDhead image are analyzed. • A movie is a convenient way to explore the maps included in a SphereSiZer atlas.…
Date: September 2018. Source: Journal of Prosthodontic Research. Purpose: It is essential to fabricate a best-fit three-dimensional (3D) facial prosthesis model capable of facial expressions. In order for the facial prosthesis to remain in position, especially around marginal areas subject to movement, a new method of making 3D facial expression models using time-series data allowing…
Date: September 2018 [Online Before Print]. Source: Journal of Surgical Research, Volume 233, pp 376-380. Background: o avoid the radiation exposure of CT imaging and the expense of CT or MRI studies, we sought to develop a non-radiographic severity measurement of pectus excavatum based on 3D photogrammetric imaging. Methods: Over 28 mo, ten consecutive patient…
Date: Aug 2018. Source: Journal of Neurosurgery: Pediatrics. Volume 22: Issue 2: pp 113-221. Objective: Deformational plagiocephaly and/or brachycephaly (DPB) is a cranial flattening frequently treated in pediatric craniofacial centers. The standard of care for DPB involves patient positioning or helmet therapy. Orthotic therapy successfully reduces cranial asymmetry, but there is concern over whether the…

Goals and Purpose: Rhinoplasty relies on clear patient communication and precise execution of a three-dimensional (3D) plan to achieve optimal results.1 3D printing is becoming more popularized in the medical field as an aid to technical planning, patient communication, and the…
Date: August 2018. Source: Nigerian Journal of Clinical Practice. Purpose: : This study aimed to evaluate the effect of a low‑level laser therapy (LLLT) on pain, trismus, and swelling of patients whose impacted 3rd molar tooth was extracted compared to placebo or “sham” treatment and measure volumetrically the edema with a three‑dimensional (3D) surface imaging…

Objective: A prospective cohort study with the overall objective to characterize the three-dimensional facial morphology of preterm infants over the course of the first 18 months of corrected age, participating in the Neonatal Follow-up Program of…
Date: July/August 2018. Source: American Journal of Human Biology, Volume 30, Issue 4. Objective: We compared digital 3D stereophotogrammetry to more traditional measurement methods (direct anthropometry and 2D scanning) to capture digit lengths and ratios. Methods: The length of the second and fourth digits was measured by each method and the second‐to‐fourth ratio was calculated.…

Objective: Orthognathic surgery with simultaneous condylectomy under digital guidance has been proved to be a feasible method to treat hemimandibular hyperplasia (HH). The objective of this study was to evaluate the effects and precision of correction of HH by…
Date: June 2018. Source: Clinical Oral Investigations. Objective: To assess the influence of involuntary facial expressions on 3D facial stereophotogrammetry reproducibility in children with and without unilateral cleft lip, alveolus and palate (UCLP) aged 3–18 months. Methods: Three to eight 3D facial images per time point were acquired within 10 min of 31 children with…
