Advances in technology are affecting every aspect of life in the 21st century, and dentistry is no exception. From diagnosis and treatment planning to all areas of dental treatment and global communications, technology is enhancing the level of patient care, practice efficiencies, and professional/patient education. In order to learn more about how a broad range of technologies can be implement...

screw-retained implant restorations have an advantage of predictable retention as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. screw-retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. the purpose of this study is to descr...

PURPOSE To report two new suture techniques for best esthetic skin healing. METHODS Using the pig skin slices routinely employed for surgical technique training two new types of skin sutures were performed. One defined as inverted or hidden X point suture and other as totally hidden intradermal running suture. The first were performed using 4-0 polypropilene stitch and the intradermal with 4-...

OBJECTIVES Esthetic dentistry is among the most dynamic areas of contemporary clinical dentistry. Teaching programs in dental schools have a strong effect on the practice of dentistry, not only for recent graduates, but also for established clinicians, especially with respect to new techniques and concepts. The purpose of the study reported here was to assess the frequency and extent of the tea...

objectives : anterior maxilla, known as the esthetic zone, plays an important role in facial and smile esthetics. this study assessed the frequency of implant treatments in the esthetic zone of patients presenting to dental implant department of tehran university during 2002-2012. materials and methods: this descriptive study was conducted on dental records of patients receiving implant treatme...

The latest world-championship competition for computer bridge programs was the Baron Barclay World Bridge Computer Challenge, hosted in July 1997 by the American Contract Bridge League. As reported in The New York Times and The Washington Post, the competition’s winner was a new version of Great Game Products’ Bridge Baron program. This version, Bridge Baron 8, has since gone on the market; and...

This case study describes the esthetic and functional reconstruction of a fractured maxillary central incisor. Due to the requirement for additional retention, treatment was performed using the homogenous technique of biological restoration associated with cementation of posts made from human dentin (biopins). This type of treatment is a new alternative to conventional techniques and favors the...

this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...

Temperature measurement is an important link in industrial production, also an important part of modern testing technology. The traditional single bridge circuit is already unable to meet the requirements of modern precise temperature measurement system on temperature measurement. The relation between the output voltage of general Wheatstone bridge and real strain is nonlinear. The nonlinear er...

one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...
