Sleeping Tongue Posture and Its Relationship to Craniofacial Morphology
… and whether such posture differs among various craniofacial morphologies. Quantifiable measurements might allow for prediction of tongue-posture-related problems specific to certain facial types. Purpose: The objective of this study was to record sleeping tongue posture over time in 27 subjects …

Variation in cranial base flexion and craniofacial morphology in modern humans
… standard from which to interpret differences in craniofacial growth and morphology. Lateral cephalometric radiographs of 414 adults representing seven samples from around the world were compared for variation in cranial base and facial morphology. The samples represent Australian Aboriginal, New …

Ancestral variation in mid-craniofacial morphology in a South African sample
… unknown skeletal remains are discovered. The mid-craniofacial region is most frequently used to estimate ancestry as this region reflects the genetic and morphological ancestry of an individual. The diverse composition of the South African population makes ancestry estimation problematic, and …

Craniofacial morphology and the consequences of intentional cranial deformation among prehistoric Andean populations
This research examined the cultural practice of cranial deformation (annular and anteroposterior), and its effects on 27 craniometric measurements and biodistances among 350 prehistoric crania from the Azapa valley of northern Chile. Included among these 27 measurements were nine facial …

Influence of Outdoor Air Quality on Maxillofacial Growth and Development
… pollution with respiratory problems, as well as craniofacial morphology with respiratory problems are well established.1-19 In this study we aimed to determine if there was a correlation between ambient air pollution and maxillofacial growth and development. We also wanted to determine if further …

CRANIOMETRIC ESTIMATION OF ANCESTRY IN PEOPLES OF INDIA
… (Cox, et al., 2009; Ousley, et al., 2009). Craniofacial measurements can be used to explore human variation and craniofacial patterns among individuals that can suggest genetic ancestral ties, and allow forensic anthropologists to effectively estimate ancestry (Jantz, 1973; Howells, 1995; …

Skeletal and dental changes with the acrylic splint Herbst appliance
… These patients were matched in sex, age and craniofacial morphology. The cephalometric system described by Pancherz was used to determine the cephalometric changes. Significant differences in skeletal and dental changes were found in patients treated with the acrylic splint Herbst when …

Dentofacial morphology in Turner Syndrome karyotypes
… aim of this thesis was to study dentofacial morphology in Turner syndrome (TS) versus controls and the influence hereupon from karyotype. One hundred thirty two TS females (5-66 years of age), from Göteborg, Uppsala and Umeå were participating. Cephalometric analysis, cast model analysis …

A finite element study of the human cranium : the impact of morphological variation on biting performance
This thesis investigated the relationship between craniofacial morphology and masticatory mechanics using finite element analysis (FEA). Chapter 1 is a literature review of the relevant background: bone mechanics, jaw-elevator muscle anatomy, imaging techniques, FEA and geometric morphometrics.The …

Assessing the accuracy of the zygoma for estimating ancestry using geometric morphometrics in a South African sample
… the local, biologically heterogenous population. Craniofacial morphology is known to be ancestrally distinct and studies are yet to explore shape and size variation in the zygomatic bone of the SA population. The aim of this study was to assess ancestral variation in zygomatic shape and size in a …

Cranial Sexual Dimorphism in Hispanics Using Geometric Morphometrics
… to maximize sample size and represent overall craniofacial morphology. A MANOVA indicates no significant differences in the expression of sexual size dimorphism among the groups, however significant sex-specific differences in size among the groups were detected. Shape differences using the …

A Biological Distance Analysis of 19th -20th -Century Individuals From Myanmar
… evolutionary trends in skeletal and dental morphology from this population sample. This research is a holistic and multi-faceted study that incorporates multiple data types (metric and nonmetric data) of the cranium and dentition to compare individuals from the Duckworth Burma collection to …

Long-Term stability of the correction of the unilateral posterior crossbite
… 50% of our cases showed a skeletal Class III craniofacial morphology.<br>- The mean change was 1.1 ± 2.8 mm in the maxillary interpremolar arch width and 2.3 ± 2.1 mm in the<br>intermolar arch width in the slow expansion groups. The RME groups showed a mean change of 3.6 ±<br>2.7 mm in …

The Phylogeny of Basal Coelurosaurian Theropods (Archosauria: Dinosauria) and Patterns of Morphological Evolution during the Dinosaur-Bird Transition
… of niche partitioning due to differences in craniofacial morphology and functional behavior. Chapter 2 presents a comprehensive new phylogenetic analysis of coelurosaurian theropods, which is an updated version (and thus the latest iteration) of the long-standing Theropod Working Group (TWiG) …

Riabilitazione protesica ed implanto-protesica di pazienti in età evolutiva affetti da Displasia Ectodermica
… used to evaluate the effect of rehabilitation on craniofacial growth. Cephalometric measurements of sound patients were compared with ED patients. After two month expander screws (three-way screw in the upper denture and two-way the lower one)were inserted in each denture in order to permit the …
