ABSTRACT Background Body pain widespreadness may be related to biopsychosocial impact in TMD (temporomandibular disorders) patients. Objectives The aim was assess, by using drawings (PDs), the whole‐body locations/widespreadness and their association with pain‐related intensity/interference clinical Axis I diagnoses among Finnish tertiary care patients DC/TMD‐FIN (Diagnostic Criteria for TMD‐FIN). Methods Based on PDs, 197 were divided into PD profile subgroups: PD‐1 (local head/face pain),...

Posterior cranial vault distraction (PCVD) is a technique widely used in surgical treatment of craniosynostosis when expansion required. It has proven to be safe and allow significant increase intracranial volume.To evaluate increases volume as result PCVD performed Oulu Craniofacial center using 2 different methods based on 3-dimensional (3-D) photogrammetric imaging or plain skull radiographs.All children less than 16 yr age who were treated by (n = 31) from 2009 2015 at the Center...

To examine the prevalence of sagittal relationships, asymmetries and midline shift, their associations with temporomandibular disorders (TMD) in Northern Finland Birth Cohort 1966 (NFBC1966).1845 subjects participated a clinical examination at age 46. Occlusal measurements were performed using 3D models. Symptoms TMD screened validated questions, signs diagnoses assessed modified protocol Diagnostic Criteria for (DC/TMD) questionnaires. Associations between variables occlusion evaluated...

Objective To evaluate the prevalence of temporomandibular disorders (TMD) and their association with sociodemographic psychosocial factors among 33- to 35-year-old Finnish adults in Northern Finland Birth Cohort 1986 (NFBC1986).

The aim of this study was to compare facial 3D analysis DNA testing in twin zygosity determinations. Facial images 106 pairs young adult Lithuanian twins were taken with a stereophotogrammetric device (3dMD, Atlanta, Georgia) and determined according similarity form. Statistical pattern recognition methodology used for classification. results showed that 75% 90% the cases, determinations similar DNA-based results. There 81 different classification scenarios, including 3 groups, features,...

Objective To resolve how the preferred chewing side (PCS) affects facial asymmetry in twins, whether there are differences between monozygotic (MZ) and dizygotic (DZ) twins with PCS have more asymmetric faces compared to symmetrically twins.Material methods The study included 106 Lithuanian twin pairs of same sex, 59 MZ 47 DZ pairs. data were analysed from 3D images manually added landmarks. by Rapidform2006 software statistical analyses done using R environment version 4.1.0.Results...

The aim of this study was to assess the stability Natural Head Position (NHP) over time using 3dMDface System.This an experimental study. Three-dimensional facial images 40 students were captured on two different occasions, with interval at least weeks.The taken a stereophotogrammetric device (3dMD). mirror positioned NHP obtained in standing position and then replicated sitting for capturing. self-balanced position. Rapidform 3D software used angle calculations. changes between positions...

Infant skull deformation is analyzed using the distribution of head normal vector directions computed from a 3D image. Severity flatness and asymmetry are quantified by functionals kernel estimate direction density. Using image data 99 infants clinical ratings made experts, our approach compared with some recently suggested methods. The results show that proposed method performs competitively.

Facial aesthetics have become one of the most important objectives orthodontic treatment. The correction dental arches should be performed in accordance with face. This study explored association between occlusal and facial asymmetries adolescents, particularly emphasizing a Class II subdivision.Eighty-one adolescents (43 males, 38 females) median age 15.9 (interquartile range, 15.17-16.33) years were enrolled. Of these patients, 30 had subdivision (right side, n = 12; left 18)....

Summary Objectives This prospective, population-based cohort study aimed to investigate the development of facial asymmetry up 6 years age using a three-dimensional (3D) soft tissue imaging method in normal population. In addition, sought identify potential predisposing factors asymmetry. Methods A total 102 newborns were enrolled at birth. 3D stereophotogrammetric images head and face analysed ages 12 months (T1), 3 (T2), (T3). The surface-based analysis involved calculation average...

Deformational plagiocephaly (DP) is considered a risk factor for facial asymmetry. This cohort-based, prospective, follow-up study used three-dimensional (3D) stereophotogrammetry to assess the development of asymmetry in normal birth cohort and investigate impact DP on age range one three years. The sample consisted 75 children: 35 girls (47%) 40 (53%) boys recruited from Oulu University Hospital. A total 23 (31%) subjects had history infancy. 3D images were obtained at mean (SD) 1.01...

Objective: The aim of this study was to find out how the preferred chewing side (PCS) affects facial asymmetry, what kind factors affect PCS, and whether there are differences in asymmetry between symmetrical asymmetrical masticators. Material Methods: included 748 subjects (females n=452, males n=296) born 1985–1986 Northern Finland (Northern Birth Cohort 1986, NFBC 1986). Subjects’ faces were captured 3D images with stereophotogrammetry technology, they filled a questionnaire concerning...

Preterm infants are at higher risk for both symmetrical and asymmetrical head molding. This study involved 3D stereophotogrammetry to assess the cranial growth, molding, incidence of deformational plagiocephaly (DP) in preterm children compared term born children. Thirty-four 34 controls were enrolled this from Oulu University Hospital, Finland. Three-dimensional images obtained age 2-4 months (T1), 5-7 (T2), 11-13 (T3), 2.5-3 years (T4) equivalent (TEA). There was no statistically...

Abstract Purpose The aim of this study was to investigate the craniofacial and aesthetic characteristics adult metopic sagittal craniosynostosis patients operated on in early childhood compared controls. goal find objective measurements that would correlate with patient’s subjective self-evaluation their own cosmetic appearance.

A novel scale space approach, SphereSiZer, is proposed for exploring structure in spherical data, that is, directional data on the unit sphere of three-dimensional Euclidean space. The method finds statistically significant gradients smooths probability density function underlying observed data. Bootstrap used to establish significance and inference summarized with planar maps contour plots overlaid arrows indicate directions magnitudes gradients. An effective way explore such a movie where...

To study, whether there are associations between chewing side preference and other lateralities, is a genetic origin for preferred (PCS), relations to sex, birth order orthodontic treatment.
