Three-Dimensional Facial Morphological Changes From Adolescence To Adulthood In Caucasian And African American Populations, Matthew Davis
Three-Dimensional Facial Morphological Changes From Adolescence To Adulthood In Caucasian And African American Populations, Matthew Davis
All ETDs from UAB
The purpose of this cross sectional retrospective study was to use three dimensional surface imaging to determine gender dimorphism and facial morphological changes from adolescence to adulthood in African American and Caucasian populations. Materials and Methods: Three-dimensional images were captured using a laser scanner (Minolta Vivid VI900) and a stereophotogrammatic camera system (3dMDfaceTM). The total sample size included 371 subjects, including the following: 107 African-American adolescents 10–13 years of age, 100 African-American adults 19–30 years of age, 64 Caucasian adolescents 10–13 years of age, and 100 Caucasian adults 18–30 years of age. All subjects had normal body mass index, no …
Three-Dimensional Age-Related Changes Of The Adult Male Face, Catherine Haynie Haynie
Three-Dimensional Age-Related Changes Of The Adult Male Face, Catherine Haynie Haynie
All ETDs from UAB
Objectives: The adult population is a fast growing subgroup of orthodontic practices. The facial soft tissues of adults are different from adolescents, and there is significant sexual dimorphism in the aging of facial soft tissue. It is imperative for the orthodontist to understand how aging effects the soft tissues of the face, and to know how male and females differ in this process. The objectives of this study include: 1.) Identification of trends in facial aging among a Caucasian male and African American male sample utilizing three-dimensional surface imaging technology. 2.) Comparison of the aging effects between the Caucasian and …
Volumetric Analysis Of The Lips In Aging African American And Caucasian Females, David William Bowen
Volumetric Analysis Of The Lips In Aging African American And Caucasian Females, David William Bowen
All ETDs from UAB
The objective of this study was to perform a volumetric analysis of the lips at rest and upon smiling in African American and Caucasian females distributed throughout five age groups. Materials and Methods: Three-dimensional surface facial images of 100 African American females and 100 Caucasian females were obtained using the 3dMDTMface system (3dMDface, Atlanta GA). Images were analyzed using the Aging Evaluation Analysis (AEVA) software (Eotech, Paris, France) to assess lip volume at rest and upon smile. The following linear measurements were also calculated upon smiling and non-smiling: subnasale-stomion superius, commissure-commissure, stomion inferius-labiomental sulcus. Gingival display and crown length was …
The Comparison Of 3-Dimensional Soft-Tissue Of Adult Korean, Chinese, And Houstonian Caucasian Patients With Class I Malocclusion, Jamie Youngshin Kim
The Comparison Of 3-Dimensional Soft-Tissue Of Adult Korean, Chinese, And Houstonian Caucasian Patients With Class I Malocclusion, Jamie Youngshin Kim
All ETDs from UAB
The purpose of this study is to compare the computer generated facial averages of Korean adults with Chinese and Houstonian Caucasian faces using a three-dimensional surface imaging system. Materials and Methods: Three-dimensional images of Korean adults (Seoul, Korea) with Class I malocclusion were captured using the 3dMDTMface, which combines structured light and stereo-photogrammetry techniques. The images of 138 Koreans were processed to generate average male and female facial shells using Rapidform 2006 Plus Pack 2 software. The average Korean facial shells were superimposed and compared to the average shells of Chinese adults (Xi’an, China) and Caucasian adults (Houston, Texas) from …
Three Dimensional Comparison Of Facial Morphology Of A Caucasian American Population And A Native Brazilian Population, William N. Turner
Three Dimensional Comparison Of Facial Morphology Of A Caucasian American Population And A Native Brazilian Population, William N. Turner
All ETDs from UAB
The aim of this study was to assess the use of 3-dimensional facial averages in determining facial morphologic differences in a Caucasian North American population and a native Brazilian population. Methods and Materials: Three-dimensional images were acquired through a commercially available stereo-photogrammetric camera system (The 3dMDfaceTM system). A total of 200 images from two population groups (Caucasian American and Native Brazilian) were taken. Each image was acquired as a facial mesh and orientated along a triangulated axis. All facial images were overlaid and superimposed, using Rapid Form 6 software to create a composite facial average of one man and one …
