In spite the fact that conventional slip-cast crowns are still largely used in everyday practice, and these techniques had shown their efficiency, selective laser sintering is a new technology which arouse more and more interest in prosthetic dentistry. One of the key factor which determines clinical success is the marginal and internal fit of fixed dental prostheses who influences the long-ter...

STATEMENT OF PROBLEM Metal-ceramic crowns are most commonly used as the complete coverage restorations in clinical daily use. Disadvantages of conventional hand-made wax-patterns introduce some alternative ways by means of CAD/CAM technologies. PURPOSE This study compares the marginal and internal fit of copings cast from CAD/CAM and conventional fabricated wax-patterns. MATERIALS AND METHO...

I N B R I E F We are used to thinking of intelligence as largely a matter of genetic inheritance, but that is not the whole picture. What we do aff ects our mental wellbeing: staying physically and mentally active helps us stay sharp as we age. Nevertheless, our personal eff orts to bolster cognitive enhancement cannot forestall all declines in our cognitive performance. What is especially surp...

The study was designed to estimate the psychometric properties of Hastings and Brown's (2002a) Difficult Behavior Self-efficacy Scale. Participants were two samples of physical educators teaching in Korea (n=229) and the United States (U.S.; n=139). An initial translation of the questionnaire to Korean and pilot study were conducted along with the larger study using a confirmatory factor analys...

OBJECTIVE To study the psychometric characteristics of German version of the Hospital Survey on Patient Safety Culture and to compare its dimensionality to other language versions in order to understand the instrument's potential for cross-national studies. DESIGN Cross-sectional multicentre study to establish psychometric properties of German version of the survey instrument. SETTING 73 un...

PURPOSE The purpose of this study was to evaluate the effect of the span length on the fit of zirconia framework fabricated using CAD/CAM system. MATERIALS AND METHODS Abutments for single, 4-unit and 6-unit fixed partial prostheses were fabricated. Ten zirconia frameworks were fabricated for each group. The marginal and internal gap were presented by means of replica technique and measured b...
