Date: July 2015 Source: Medicine Science | International Medical Journal. Abstract: The facial morphologies of identical twins were compared using the 3dMD three-dimensional (3D) photogrammetry system. 3D images of the faces of 27-year-old identical twins were acquired and then superimposed. The differences were shown in a color histogram generated using 3dMD Vultus software. The faces…

Date: June 2015. Source: Journal of Oral & Maxillofacial Surgery. Purpose: To fulfill the requirements of computer-aided orthognathic surgery, we developed a method of recording head positions in pitch and roll, and tested its accuracy and reliability. Materials and Methods: A laser level was used to project a horizontal laser line onto a volunteer’s face.…

Date: June 25, 2015. Source: European Craniofacial Congress 2015, Gothenburg, Sweden. Summary: 3D imaging is an established tool for facial measurement and documentation of craniofacial patients. To date, little data exists about the accuracy of measurements of the whole head in 3D photography, particularly where the presence of hair may impair measurements. 21 patients who…
