Die biomechanische Analyse des Kiefergelenks mit Hilfe eines neuen Echtzeit-MRT-Verfahrens
(2024-04-03)Aim: The traditional hinge axis theory of temporomandibular joint (TMJ) dynamics is increasingly being replaced by the theory of instantaneous centers of rotation (ICR). Typically, ICR determinations are based on theoretical ... -
Elektronische Achsiographie vor und nach Schienentherapie zur Objektivierbarkeit möglicher Veränderungen der Grenzbewegungen des Unterkiefers
(2023-10-19)Introduction. Occlusal splint therapy is widely used in the treatment of myofascial pain, but valid studies quantifying the efficacy of this therapy are rare. The aim of the present study was to investigate which quantifiable ... -
In-vitro-Untersuchung zur mikrobiellen Adhäsion von Streptococcus mutans und Candida albicans auf verschiedenen Schienenmaterialien
(2023-10-06)Aim: The aim of the present in vitro study was to investigate the effect of different manufacturing processes of oral splint resins on the microbial adhesion of Streptococcus mutans and Candida albicans. Materials/Methods: ... -
In-vitro- und In-vivo-Messungen der statischen und dynamischen Okklusion in der Totalprothetik
(2023-02-23)Introduction: In reconstructive dentistry there exists the difficulty that articulators can only approximately imitate the patient's jaw relation due to the complex biomechanics. In addition, certain dimensional changes ... -
Prävalenz von Allgemeinerkrankungen bei diagnostizierten Craniomandibulären Dysfunktionen – eine Fall-Kontroll-Studie
(2023-02-13)Symptoms of pain-associated temporomandibular disorders (TMD) are relevant in clinical practice as they affect 2,7 – 10 % of the population. Based on the biophychosocial model, the etiology is accepted as multifactorial ... -
In-vivo-Biofilmakkumulation auf implantatprothetischen Werkstoffen
(2021-07-12)AIM. The aim of this in vivo study was to investigate the biofilm formation on the surface of four different implant abutment materials (titanium, zirconia, PEEK, BioHPP). MATERIAL/METHODS. Split specimens were ... -
Untersuchung zur Reliabilität elektronischer Registriersysteme am Beispiel des ARCUSdigma II
(2021-05-27)In digital axiography relative motions of the mandible are recorded with a paraocclusal mounted writing bow and a facebow attached to the head. The attachment of the writing bow is either carried out by individualized ... -
Tageszeitabhängige Abweichungen der statischen und dynamischen Okklusion
(2021-04-20)Introduction. Occlusion, i.e. the sum of contacts between teeth of the maxilla and mandible, plays a decisive role in the pathogenesis of temporomandibular disorders (tmd) and in restorative therapy. Static and dynamic ... -
Evaluierung bestehender Prüfungsmodalitäten in der Zahnärztlichen Vorprüfung und Implementierung neuer Prüfungsstrukturen
(2019-04-01)Background: the curriculum of dental education comprises several practical examinations, which are commonly assessed by using the so called ‚glance-and-grade‘ method. Without referring to specified criteria, valid check ... -
In-vitro-Untersuchung zur initialen Biofilmbildung auf dentalen Kompositmaterialien
(2018-10-10)Objective: The aim of the present in vitro study was to investigate the effects of minimal differences in the composition of composite filling materials, i.e. different color mixtures, on the initial bacterial colonizati ... -
In-vitro-Untersuchung der antimikrobiellen und zytotoxischen Eigenschaften eines kupferhaltigen Zinkoxidphosphatzementes
(2017-11-10)AIM The aim of this in vitro study was to evaluate the biocompatibility and the antimicrobial effect of a copper-loaded zinc phosphate cement in comparison to a conventional unloaded reference cement. MATERIALS/METHODS Two ... -
In-vitro-Untersuchung zur Zytotoxizität kieferorthopädischer Kunststoffe
(2017-07-20)The aim of this study was to evaluate and to compare cytotoxicity and roughness of the autopolymerized orthodontic acrylic resin Weitur® and the photopolymerized Orthocryl® LC. Also possible relationships between cytotoxicity ... -
Die in vivo antibakterielle Wirkung von Kupfer in einem zahnärztlichen Zinkoxid-Phosphatzement
(2017-04-24)Antibacterial additives of medical biomaterials have been introduced as a promising approach to reduce the risk of infection. The aim of this study was to investigate antimicrobial effects of copper in a dental zinc phosphate ...
