Orthodontic treatment is a common dental procedure in developed countries. However, the frequency and factors associated with treatment demand are different between countries. The aim of this study was to examine the frequency of orthodontic treatment in German children and adolescents and to analyse the influence of age, gender, and socio-economic status(More)
The purpose of this study was to evaluate the occlusion of all-ceramic onlay surfaces generated with a laboratory (LAB) and computer-aided design/computer-assisted manufacturing (COMP) system. The treatment of the mandibular left first molar was simulated on 16 casts. A minimum of three static contacts and their localization were defined beforehand (MIN3).(More)
INTRODUCTION Therapy of cleft patients aims to control bone growth and tooth development so as to ensure a secure occlusion with good function. This paper aims to uncover the potential and limits of achieving neutral occlusion in patients with clefts of lip, alveolus and palate. Two treatment approaches are presented and compared with respect to the best(More)
Based on endogenous Streptomyces plasmids we have constructed various multiple purpose vectors for cloning in streptomycetes. Since replication of the S. ghanaensis plasmid pSG5 is inherently temperature-sensitive, pGM-vectors derived from pSG5 can be used for gene disruption/replacement and mutational cloning. The 1.6-kb minimal replication region of pSG5(More)
Palatal muscle biopsies from the cleft margin of children were subjected to cytophotometrical and immunohistochemical analysis. Muscle fiber types were classified according to the enzyme activity of myofibrillic adenosine triphosphatase, glycerol-3-phosphate-dehydrogenase and succinate dehydrogenase assessed cytophotometrically. Fiber type-related(More)
OBJECTIVES This study aims to describe morphological peculiarities of maxillary and mandibular first molars in Europeans, Asians and Europeans with cleft lip and palate. MATERIAL AND METHODS Reflex microscopy was used to obtain three-dimensional morphometric landmarks from 40 models (11 Europeans and 13 Asians without cleft lip and palate, 16 Europeans(More)
The aim of this study was to examine the extent to which the ratio of the endochondral growth components cell volume increase to matrix production was subject to age-dependent and animal-specific changes per cell in the condylar cartilage of the domestic pig. In addition, it was to be investigated whether the cell distribution in the condylar cartilage and(More)
The connection of a device for the registration of mandibular movements depends on the coupling of the teeth with a paraocclusal adapter. This is normally done by individualizing a prefabricated metal support, either directly on the patient or in the dental laboratory. The goal was to create an individual paraocclusal adapter by means of additive(More)
OBJECTIVES Evidence on possible associations between facial morphology, attachment loss and gingival recession is lacking. We analysed whether the facial type, which can be described by the ratio of facial width and length (facial index), is related to periodontal loss of attachment, hypothesizing that a broad face might be associated with less gingival(More)
Today, orthodontic treatment with fixed appliances is usually carried out using preprogrammed straight-wire brackets made of metal or ceramics. OBJECTIVE The goal of this study was to determine the possibility of clinically implementing a fully digital workflow with individually designed and three-dimensionally printed (3D-printed) brackets.
