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.
The accuracy of movement recordings was excellent at all speeds (60, 30 and 15 fps), with variability in MAD values consistently being less than 1 mm. The reliability of the camera recordings was excellent at all recording speeds.
There was a longitudinal decrease in soft tissue volume and depth difference in extraoral soft tissues in the region of implant placement after surgery up to 6 weeks. The use of a facial scanner is a promising noninvasive method to monitor 3D morphometric changes after implant surgery.
This pilot study aimed to evaluate, for the first time, the changes in facial tissues following the placement of a single dental implant.
