BACKGROUND Traumatic injuries caused to anterior teeth are most common. Emergency management of fractured fragments is necessary, for preserving their vitalities and for retaining aesthetics in an economical way. Various methods are available for restoring fractured, uncomplicated teeth, such as reattachment of fractured fragments, composite restoration. But only limited data is available on ev...

OBJECTIVE To investigate the influence of location and preparation design on the survival and complication rate of metal-free polymer crowns within a prospective clinical study. METHODS After randomization, a total of 114 (68 posterior and 46 anterior) single crowns were prepared, either with a chamfer finishing line or with a shoulder combined with occlusal reduction of at least 1 mm. Build-...

Recently, various methods for 6D pose and shape estimation of objects have been proposed. Typically, these evaluate their in terms average precision reconstruction quality chamfer distance. In this work, we take a critical look at predominant evaluation protocol, including metrics datasets. We propose new set metrics, contribute annotations the Redwood dataset, state-of-the-art fair comparison....

This paper analysis heat transfer and angular velocity of micropolar ethylene-glycol nanofluid over the triangular, rectangular chamfer fins on stretching sheet. The innovation this is to investigate parameters flow passing from different surface. finite Element Method selected for solving governing equations. temperature in space warm equal surface temperature. value 30 degrees. maximum values...

Polycrystalline Diamond (PCD) Cutters are ultra-hard tools used for oil and gas drilling. These can fail in the form of spalling due to impact. In this paper, direct impact quasi-static loading investigate failure force leached PCD cutters when loaded at an angle on edge their chamfer with a striker or platen. Impact experiments were performed using impedance match system which ensures sample i...
