INTRODUCTION Ever since the introduction of the minimal preparation fixed partial dentures, the major concern of the clinicians has been its longevity. AIMS AND OBJECTIVE The objective of the present study was to compare the clinical performance of resin bonded cantilever bridges with conventional cantilever bridges for a period of 1 year and to evaluate the periodontal changes of abutment te...

Background: Myocardial bridging is recognized as an anatomical variation of the human coronary circulation in which an epicardial artery lies in the myocardium for part of its course. Thus, the vessel is ‘bridged’ by myocardium. The possible clinical implications of myocardial bridging may vary from protection against atherosclerosis to systolic vessel compression and resultant myocardial ische...

Intestinal epithelia have a brush border membrane of numerous microvilli each comprised of a cross-linked core bundle of 15-20 actin filaments attached to the surrounding membrane by lateral cross-bridges; the cross-bridges are tilted with respect to the core bundle. Isolated microvillar cores contain actin (42 kD) and three other major proteins: fimbrin (68 kD), villin (95 kD), and the 110K-ca...

An experimental apparatus to study the breaking process of axisymmetric liquid bridges has been developed, and the breaking sequences of a large number of liquid bridge configurations at minimum-volume stability limit have been analyzed. Experimental results show that very close to the breaking moment the neck radius of the liquid bridge varies as t, where t is the time to breakage, irrespectiv...

This article reviews the literature on planning the support of bounded saddles of removable partial dentures or fixed bridges. Three-dimensional photoelastic analysis was used to examine stresses on removable partial dentures of different designs, and possible model structure changes raised for further investigation.

The present article introduces a new technique for chairside provisional fixed partial dentures fabrication. The described direct technique is suitable for a fast and relatively easy fabrication of provisional single crowns or small bridges. It does not necessitate any preliminary laboratory stages (such as wax-up e.g.) but rather tends to adapt the teeth morphology of a selected model to the s...

Introduction: The aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. Methods: Three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. Results: Larger nodules and poros...
