OBJECTIVE The aim of the present review was to evaluate the bone integration efficacy of recently developed and marketed oral implants as well as experimental surface alterations. MATERIALS AND METHODS A PubMed search was performed for animal studies, human reports and studies presenting bone-to-implant contact percentage or data regarding mechanical(More)
The prognosis of idiopathic sudden hearing loss depends on its severity; acute complete deafness, for example, has a particularly bad prognosis. The treatment of acute deafness is based on a systemic application of corticosteroids. Corticoid concentrations in the cochlea are higher after transtympanic application in comparison to systemic application. We(More)
This systematic review focused on the question, if and to what extent enamel matrix derivative (Emdogain) [EMD]) promotes the regeneration of bone. The influence of combinations with other biomaterials was additionally evaluated. Twenty histomorphometric studies were included in this systematic review. Main results of the reviewed articles were (i) guide(More)
Collagen barrier membranes are frequently used in both guided tissue regeneration (GTR) and guided bone regeneration (GBR). Collagen used for these devices is available from different species and is often processed to alter the properties of the final product. This is necessary because unprocessed collagen is rapidly resorbed in vivo and demands for barrier(More)
With the increasing number of orthodontic treatments using devices containing nickel and the growing prevalence of nickel allergy in the average population, biocompatibility studies of these devices have become a topic of major interest. The corrosion behavior of orthodontic wires is a decisive factor determining their biocompatibility. Therefore four(More)
BACKGROUND New microplasma spray (MPS) equipment to deposit calcium phosphate (CaP) ceramic coatings onto titanium substrates has been developed. With this apparatus, it is possible to spray fine particles, as well as to apply textured hydroxylapatite coatings onto titanium surfaces. Moreover, due to the low heat power of the microplasma jet, overheating of(More)
AIM The present study aimed to evaluate and compare two types of implants, i.e. grit-blasted and acid-etched implants (SLActive(®)) with nano-meter-scale hydroxyapatite surface-modified implants (NanoTite™). MATERIAL AND METHODS For histological and histomorphometrical evaluation, 22 SLActive(®) and 22 Nanotite™ implants were inserted in eleven Beagle(More)
BACKGROUND Osteoporosis is a frequent human metabolic bone disorder. Prospectively, global ageing of populations will lead to a major increase of subjects being diagnosed with osteoporosis and in need for dental rehabilitation. However, as local osteoporosis of the jaws affects bone quantity and quality of edentulous regions, osseointegration of dental(More)
Application of enamel matrix protein derivative (EMD) onto a debrided and conditioned root surface has been shown to promote periodontal regeneration in animals and humans. However, until now there is virtually no information from humans describing the expression of different matrix molecules in the newly formed periodontal tissues following treatment with(More)
The aim of the study was to investigate immunohistochemically the expression of matrix molecules associated with periodontal tissues reformed after regenerative periodontal treatment. Chronic intrabony defects were treated with guided tissue regeneration, enamel matrix proteins, the combination of both, or access flap surgery. Five months after healing, the(More)
