The purpose of this study was to classify and characterize facial asymmetry (FA) phenotypes in adult patients with unilateral cleft lip and palate (UCLP) and skeletal class III malocclusion. The sampl...
To explore the normal variation of asymmetry in mandibles of children in the age group of 1 to 12 years....
The study group consisted of 92 cadaveric mandibles of children with a dental age of 1 to 12 years old in possession of ACTA (Academic Centre for Dentistry Amsterdam), Faculty of Dentistry, the Nether...
No relationship was found between dental age and asymmetry of the studied parameters (P < .05). The highest degree of asymmetry was found in the ramus height, whereas the gonial angle presented the lo...
Mandibular asymmetries in children did occur (9.8% of the included mandibles presented with a relevant overall asymmetry of ≥3%) and were unrelated to age. The different segments of the mandible seem ...
To evaluate the development of the craniofacial region in healthy infants and analyze the asymmetry pattern in the first year of life....
The participants were grouped by sex and age (1, 2, 4, 6, 9, and 12 months) to receive three-dimensional (3D) photographs. Stereoscopic craniofacial photos were captured and transformed into a series ...
A total of 373 photographs from 66 infants were obtained. In both genders, the highest and lowest growth rates for all anthropometric indices were noted between 1 and 2 months and between 9 and 12 mon...
A longitudinal evaluation of the craniofacial growth of healthy infants during their first year of life was presented....
Mandibular asymmetry is among the most common facial anomalies. Traditionally, mandibular asymmetry with malocclusion has been treated with orthognathic surgery and genioplasty. However, routine genio...
Mandibular asymmetry refers to dimensional differences between the left and right sides of the mandible in terms of size, form and volume. This condition may result in problems with functionality as w...
To evaluate three of the main verbal models that have been proposed to explain the relationship between fluctuating asymmetry and fitness in humans: the "good genes," the "good development," and the "...
A formal model was generated for each verbal model following three steps. First, based on the literature, a theoretical causal model and the theoretical object of inquiry were outlined. Second, an emp...
The results suggest that the theoretical and empirical assumptions of the "good genes" hypothesis should be reformulated. The results were compatible with most of the empirical assumptions of "the goo...
Although the three hypotheses focus on different aspects of the link between asymmetry and fitness, their overlap opens the possibility of a unified theory on the subject. The results of this study ma...
Facial asymmetry is a common problem seen in orthodontic clinics that may affect patient esthetics. In some instances, severe asymmetry that affects patient esthetics may cause psychological issues. A...
We used three-dimensional (3D) facial images and landmark-based anthropometric analysis to construct a 3D facial mask to evaluate asymmetry. The landmark coordinates were transformed using a symmetric...
The preliminary results demonstrated that the asymmetry evaluation method had a similar response rate compared to diagnosis using mirror and overlap 3D images, and could therefore identify 3D asymmetr...
By using 3D facial scans and 3D anthropometric analysis, we developed a preliminary evaluation method that provides objective parameters to clinically evaluate patient facial asymmetry and aid in the ...
This study presents a novel facial asymmetry diagnostic method that has the potential to aid clinical decisions during problem identification, treatment planning, and efficacy evaluation....
To develop a novel and simplified parameter for mandible angle asymmetry (MAA) evaluation for facial countering surgeries in Chinese females....
A total of 250 craniofacial computer tomography of healthy Chinese individuals were collected in this retrospective study. Mimics 21.0 was applied for 3-dimensional anthropometry. The Frankfort and Gr...
Mandible angle asymmetry was divided into horizontal and vertical asymmetry. No significant differences were found in either horizontal or vertical orientations. The horizontal difference was 3.09±2.5...
This study provided a novel parameter for asymmetric evaluation in the mandible angle region through quantitative 3-dimensional anthropometry, arousing plastic surgeons' attention to both aesthetics a...
This study aimed to assess the correlation of social smile symmetry with facial symmetry....
In this cross-sectional study, frontal view photographs were obtained from 169 eligible patients at rest and smiling with a camera at the level of their nose tip. Several landmarks were selected for f...
Significant correlations were noted between Oc-b AI (smile) and Sn-B (rest) facial AI (P = 0.046), An-a (smile) AI and Gn-a (rest) facial AI (P = 0.002), An-b (smile) AI and Sn-b (rest) facial AI (P <...
A significant correlation exists between social smile symmetry and facial symmetry....
Facial aesthetics have become one of the most important objectives of orthodontic treatment. The correction of dental arches should be performed in accordance with the face. This study explored the as...
Eighty-one adolescents (43 males, 38 females) with a median age of 15.9 (interquartile range, 15.17-16.33) years were enrolled. Of these patients, 30 had a Class II subdivision (right side, n = 12; le...
The surface matching scores were 59.0% ± 11.3% for the whole face and 39.0% ± 19.2% for the chin. Chin volume was larger on the right side than on the left side in most patients (n = 51, 63%), and it ...
Dental asymmetry was weak but significantly correlated with facial asymmetry....
