statement of problem: the connector area is the weakest zone of an all-ceramic fixed partial denture (fpd), where most catastrophic failures of the prostheses tend to occur. purpose: the aim of the present study was to assess the effect of the convergence angle of abutments on the fracture resistance of three-unit fixed partial dentures made of ips-empress2. materials and methods: forty extract...

 Many existing bridges were designed without adequate consideration of seismic risk. The full or partial collapse of even one major bridge in a city or community would have destroying results. There has been focuses on developing fragility-based seismic vulnerability of existing usual bridges in Iran or support decision making on seismic upgrade. This article focuses on developing performance b...

The aim of this study was to find out patients' satisfaction with their bridges made of different materials (metal-ceramics, Au/resin, Ag-Pd/resin). One hundred and sixty four patients were examined at the Dental School, University of Zagreb, Croatia. They assessed their bridges--the overall quality, aesthetics, speech, chewing and the health of the gingiva by the scale from 1-5. The same categ...

Automatically detecting geographical objects such as bridges, roundabouts or road crossings on highresolution satellite images is useful for keeping up to date geographical databases, automatically locating the imaging satellite at low cost, and easily and quickly assessing the extent of damages in case of natural disasters such as flooding or earthquakes. In addition, it may help in content-ba...

Finite element analysis methods have been used to calculate the effects of trimming bridges on the first several frequencies of vibration. Violin bridges and both standard and Belgian designs of cello bridges have been investigated. Calculations of both in-plane and out-of-plane vibrating modes have been made when the feet were rigidly fixed. In one case, no motion out-of-plane was permitted. I...

In a continuing effort to provide a solution, engineers in the Construction and Technology Division (C&T) of the Michigan Department of Transportation (MDOT) are studying alternative bridge deck designs. C&T engineers are six years into a study which could eventually save Michigan motorists a considerable amount of tax dollars. The study compares the performance of isotropic bridge decks with d...

Since its first description in 1922, the incidence and pathophysiologic significance of myocardial bridges has remained controversial due to the relatively small size and retrospective design of most studies. We assessed the incidence and clinical consequence of myocardial bridges in 2547 patients undergoing coronary arteriography over a 16-month period at our medical center. Of the 511 patient...

conclusions intelligence care is a comprehensive strategy that in addition to recognizing barriers and bridges of nursing care, with predisposing and precipitating forces it can convert barriers to bridges. results intelligence care emerged as a main theme, has a broad spectrum of categories and subcategories with bridges and barriers, including equality of bridges and barriers (contingency car...

Replacement of missing dentition is one of the important needs for patients. It is common reason to attend a dental practice for individuals who wish to restore their aesthetics and function1. There are a variety of treatment modalities for the replacement of a single missing tooth i.e. a removable partial denture, a fixed partial denture or an implant supported restoration. Each of these treat...

UNLABELLED The replacement of crowns and bridges is a common procedure for many dental practitioners. When correctly planned and executed, fixed prostheses will provide predictable function, aesthetics and value for money. However, when done poorly, they are more likely to fail prematurely and lead to irreversible damage to the teeth and supporting structures beneath. Sound diagnosis, assessmen...
