On average, the lateral cephalometric radiographs might provide an adequate representation of the facial profile, but when individual patients are considered, there is often a clinically significant error. Thus, lateral cephalograms should be used with caution to evaluate the facial soft-tissue profile.
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).
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.
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.
The 3D geometric morphometry in OAVS patients could be a useful tool for objective facial asymmetry assessment in patients with OAVS.
To establish and validate a novel method to orient a 3-dimensional (3D) facial model to natural head position (NHP) in a stereophotogrammetric system using a 2-dimensional frontal full-face photograph of NHP.
Preoperative and 9-month follow-up cone-beam computed tomography (CBCT) and 3dMD images were obtained, superimposed, and quantified for skeletal movements and soft tissue changes in six facial regions.
