Dentofacial aesthetics and quality of life
2007
This article reviews, from the socio-psychological perspective on physical attractiveness, recent research on the psychosocial impacts of dental aesthetics. Research on personal impression forming suggests that visual perceptions of detrimental dental conditions might lead to conclusions about social impairments of the target person. Consumers conform considerably with professional assessment of dental aesthetics. Psychosocial impacts of dental appearance in childhood include teasing by peers. Existing research suggests that dental aesthetics contributes to psychosocial well-being of both children and adults. The concept of public self-consciousness is introduced for explaining differences …
Über den Wert ästhetischer Normen im Rahmen der Profilbeurteilung
1984
In der vorliegenden Arbeit wurde untersucht, ob die bei verschiedenen Analysen des Weichteilprofils angegebenen Normen dem entsprechen, was Laien als schon beurteilen und inwieweit das jeweilige Kriterium geeignet ist, zwischen schon und haslich zu differenzieren. Zwei Untersuchungsmaterialien standen zur Verfugung. Im ersten Teil hatte eine Beurteilergruppe 27 konstruierte Strichzeichnungen von Profilverlaufen auf Ratingskalen zu beurteilen. Im zweiten Teil wurden in ahnlicher Weise 70 Schattenris-Profile beurteilt. Als Ergebnis stellten wir fest, das die untersuchten Beurteilungsverfahren fur das Weichteilprofil nur einen geringen Wert haben, weil jedes fur sich nur wenig geeignet ist, zw…
Gait Symmetry Analysis in Patients after Treatment of Pilon Fractures by the Ilizarov Method
2021
The aim of this study was to comprehensively assess the gait parameters in patients who had undergone treatment of pilon fractures by the Ilizarov method. We analyzed gait parameters in patients who had undergone treatment for pilon fractures by the Ilizarov method
Holographische Untersuchung zur Darstellung initialer Verformungen eines mazerierten menschlichen Schädels unter der Einwirkung einer orthopädischen …
1995
Das Phanomen der Oberkieferverformung und der resultierenden Wachstumsveranderungen unter der orthopadischen Wirkung des Headgears ist sehr komplex und wenig erforscht. Ziel der vorliegenden Arbeit war es, mit Hilfe der holographischen Interferometrie die initiale Knochenverformung des Oberkieferkomplexes nach der Einwirkung verschiedener Zugrichtungen eines Headgears zu untersuchen. Ein oberhalb, unterhalb und durch das Widerstandszentrum der ersten bleibenden Molaren gerichteter okzipitaler, zervikaler und Kombinationszug wurde mit 560 g an einem mazerierten menschlichen Schadel simuliert. Die Registrierung der dabei stattfindenden knochernen Veranderungen fand mit Hilfe der Laserholograp…
Stiff landings are associated with increased ACL injury risk in young female basketball and floorball players
2016
Background: Few prospective studies have investigated the biomechanical risk factors of anterior cruciate ligament (ACL) injury. Purpose: To investigate the relationship between biomechanical characteristics of vertical drop jump (VDJ) performance and the risk of ACL injury in young female basketball and floorball players. Study Design: Cohort study; Level of evidence, 3. Methods: At baseline, a total of 171 female basketball and floorball players (age range, 12-21 years) participated in a VDJ test using 3-dimensional motion analysis. The following biomechanical variables were analyzed: (1) knee valgus angle at initial contact (IC), (2) peak knee abduction moment, (3) knee flexion angle at …
Prevalence of maxillary canine impaction in skeletal Class III malocclusions compared to Class I malocclusions
2019
Background The aim of the present investigation was to evaluate if an orthodontic population of Class III malocclusion patients shows a different prevalence of maxillary canine impaction than Class I subjects. Material and methods Fifty-eight subjects were retrospectively selected and assigned to the Class I group (n= 32) or the Class III group (n= 26), depending on the ANB and WITS values. Lateral cephalograms were used to collect angular and linear measurements that described the skeletal and dental maxillary features of the subjects, while orthopantomography was used to assess the impaction or the correct eruption of the maxillary canines. An independent samples T-test or a Mann-Whitney …
Detecting Ankle Instability With an Instrumented Ankle Arthrometer: An Experimental Study.
2019
A new instrumented device was developed to quantify ankle joint stability during an anterior talar drawer test. The aim of the present study was to validate this device comparing bone kinematics with arthrometer measurement outcomes. An anterior talar drawer test was performed with 14 cadaver legs using a custom instrumented ankle arthrometer. Using clusters of bone-pin markers, the relative three-dimensional movement of calcaneus, talus, and fibula was simultaneously measured. Anterior drawer test was applied on the intact foot and after sequentially sectioning the anterior talofibular ligament, the calcaneofibular ligament, and the posterior talofibular ligament. Cutting the anterior talo…
Predictive validity of the GOSLON Yardstick index in patients with unilateral cleft lip and palate: A systematic review
2017
Among the various indices developed for measuring the results of treatment in patients born with unilateral cleft lip and palate (UCLP), the GOSLON Yardstick index is the most widely used to assess the efficacy of treatment and treatment outcomes, which in UCLP cases are closely linked to jaw growth. The aim of this study was to conduct a systematic review to validate the predictability of growth using the GOSLON Yardstick in patients born with UCLP. A systematic literature review was conducted in four Internet databases: Medline, Cochrane Library, Scopus and Embase, complemented by a manual search and a further search in the databases of the leading journals that focus on this topic. An el…
Presurgical Preparation of Infants With Unilateral Cleft Lip and Palate: The SAC-PP-MR Innovative Technique
2018
In this article, we demonstrate an effective, cheap, and fast way to shape the nasal alar cartilage in patients with unilateral cleft lip and palate. This technique straightens the vomer and brings the philtrum, columella, premaxilla, and the maxillary frenum to the midsagittal plane, while the alveolar ridges are shaped and positioned. This reduces the lip and palatal cleft to zero even in a 4-week period.
Thermographic Analysis of Tooth Vascularization Using Thermal Stimulation
2018
Objective: The current pulp diagnostic techniques based on subjective patient response to electrical or thermal stimuli are unable to assess tooth vascularization, which is a true indicator of pulp vitality. The present study evaluates thermography as a pulp vitality test, assessing tooth recovery following thermal stimulation. Methods: A model simulating intrapulpal circulation was developed. Superficial thermographic measurements were obtained from teeth with and without elevation of the intracoronal temperature before and after applying thermal stress with cold. The data were analyzed using analysis of variance (ANOVA), and the level of significance was set at P<0.05. Results: The model …
