A 3dMDface system captured 3D facial images of each patient in both the closed-mouth position and in MIP, using cheek retractors for exposure.
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).
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.
This study indicates that facial asymmetry significantly increases with age and is significantly larger in males than in females.
This study confirmed the strong correlation between facial phenotype and airway parameters in Crouzon syndrome patients.
In summary, this study will serve as evidence to guide clinicians in deciding whether to perform the T&A on patients prior to functional therapy based on a wide range of objectively and subjectively measured outcomes and provide a reference for multidisciplinary management of OSA with craniofacial alterations in growing children.
