Obesity is a chronic disease whose origin is determined by genetic factors as well as environmental influences. The prevalence has rapidly increased worldwide in the recent decades. This paper evaluated the research on obesity in the period of 1900 - 2009 in the ISI "Web of Science" by Thomson Reuters. For this purpose scientometric methods were used and the results were graphically illustrated by "Density Equalizing Map Projections". From 1900 till 2009 94.987 published items are the basis for the present qualitative and quantitative data analysis. The publication rates show an exponential growth indicating a pronounced research activity. Concerning the country comparison the United States has the highest number of publications and citations, the highest modified h-index and most academic institutions. This manuscript shows the first comprehensive scientometric data on obesity. In this research area, the United States is a leader and is located at the center of global collaborations.
Completely digital workflows for the fabrication of implant-supported removable restorations are not yet common in clinical dental practice. The aim of the current case report is to illustrate a reliable and comfortable workflow that reasonably merges conventional and digital workflows for the CAD/CAM‑fabrication of implant-supported overdentures. The 53-year old patient was supplied with a digitally processed complete denture in the upper jaw and, simultaneously, with an overdenture supported by four interforaminal implants in the lower jaw. The overdenture included a completely digitally processed and manufactured alloy framework that had been fabricated by selective laser sintering. The case report indicates that digital manufacturing processes for extensive and complex removable restorations are possible. However, as it is currently not yet possible to digitally obtain functional impressions, future developments and innovations might focus on that issue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
