This study included a cohort of 47 patients who were admitted to the Peking University Hospital of Stomatology between 2013 and 2020 for maxillary resection procedures, necessitated by tumours.
A non-ionizing method for facial diagnosis and orthodontic treatment planning combines 3D stereophotogrammetric facial imaging (3dMD) and 3D intra-oral scanning (3Shape).
Between September 2016 and April 2018, all 118 middle-aged Caucasian male subjects were capture with the 3dMDface.t System using a novel technique for the registration of head position during image acquisition. The 3D surface structures were assessed using 3dMDvultus software and 36 surface variables were analyzed including linear, angular measurements, and proportions.
All patients underwent 3dMD scans prior to orthodontic treatment. Then the differences in the 3D morphological parameters of the facial soft tissues were compared between different sexes and different types of malocclusion.
The study included 120 individuals, 60 each in the nasal breathing (NB) and mouth breathing (MB) groups.
Orthodontic treatment has brought changes in facial soft and hard tissues, which has a potential effect in personal identification.
3dMD records of three infants were taken before NAM(T0), after NAM(T1) and one month after surgery(T2).
This study aimed to investigate the impact of head circumference on the accuracy of three-dimensional (3D) facial scans, focusing on trueness and precision.
