Laboratory-manufactured gold, ceramic and composite inlays were compared with the CAD/CAM produced CEREC inlay experimentally and clinically. The following systems were examined: Dicor, Optec, Hi-Ceram, Du-Ceram, Cerec, Kulzer, Coltene, SR-Isosit composite inlays, and gold inlays (Degulor C) with adhesive fixation (group I) and with zinc oxide phosphate(More)
In this prospective study, 120 teeth consisting of maxillary and mandibular canines and premolars were divided into three groups each containing 40 teeth. The teeth were assigned randomly in quadrants to three different periodontal treatment protocols. The first group was treated with professional prophylaxis only. The second group received additional deep(More)
Since the introduction of crown software for Cerec, it has been possible to produce full-ceramic crown restorations. Despite the excellent material quality of industrially made ceramic blocks and the good clinical long-term success of these ceramics in inlay- and onlay preparations, extended preparation with high loss of dental tissue is incident to crown(More)
The prosthetic treatment of CLAP patients is usually done in three phases: an interceptive treatment during two stages of orthodontics, the definitive prosthetic treatment and usually the secondary treatment. In the interceptive phase we use clasp-retained partials; the definitive treatment is achieved mostly by telescope-retained partials. There is seldom(More)
In recent years, spectacular defaults, such as Barings, as well as new requirements from the Basel Committee on Banking Supervision (Basel II) have forced banks to start measuring and managing operational risks (OpRisk) risks arising from the failure of people, processes, systems and external events. Contrary to market and credit risk, there are no standard(More)
Fluorescence spectroscopy and microscopy are powerful techniques to detect dynamic properties in artificial and natural lipid membrane systems. Unfortunately, most fluorescent dyes that sense dynamically relevant membrane parameters are UV sensitive. Their major disadvantage is a high susceptibility to fluorescence bleaching. Additionally, the risk for(More)
