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.
The aim of this study was to clarify the hard-soft tissue relationships of the lower 1/3 of the face in skeletal Class II-hyperdivergent patients compared with those in Class I-normodivergent patients using network analysis.
The 3dMDface system was used to capture the nasolabial morphology of the individuals.
We conducted this study to identify phenotypes of obstructive sleep apnea (OSA) in children based on lifestyle, sleep habits, age, obesity, sex, soft tissue facial features, and specific craniofacial abnormalities.
When the nasal tip protrusion decreased, the subjects all had the visual illusion of upper lip protrusion; and when the nasal tip protrusion was too large, the general population had the most obvious visual illusion of upper lip protrusion.
