3dMD Customer Research, Genetics, Medical, Plastics

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.…

Three‐dimensional facial phenotyping in obstructive sleep apnoea. RWW Lee.

3dMD Customer Research, Dental, Medical, 3dMDface, Craniofacial/Cleft, Multimodal (CT/CBCT), Oral and Maxillofacial, Orthognathic, Otolaryngology, 3dMDface System

Date: June 2018 Source: Respirology, Volume 23, Issue 6, pp 560-561. Abstract: Craniofacial structure is an important anatomical determinant of obstructive sleep apnoea (OSA). While obesity is the major attributing risk factor for OSA, it is well established that a restricted craniofacial bony skeleton also contributes to a more collapsible upper airway, which is a…

Cranial growth in infants. A longitudinal three-dimensional analysis of the first months of life. P Meyer-Marcotty, F Kunz, T Schweitzer et al.

3dMD Customer Research

Date: June 2018. Source: Journal of Cranio-Maxillofacial Surgery, Volume 46, Issue 6, pp 987-993. Objective: In the first months of life, any deviation from a physiological growth pattern can cause skull deformity. As there has not been any longitudinal three-dimensional (3D) study investigating the physiological growth of the infant skull, the aim of the present…
