Magnetically driven soft actuators are unique because they fast, remote-controlled, conformal to rigid objects, and safe interact with humans. Despite these multiple functionalities, a broader utilization of such is hindered by the high cost equipment-intensive nature currently available manufacturing processes. Herein, simple fabrication route for magneto-responsive described using cost-effect...

The aim of this study was to evaluate the effect of unilateral misfit at different levels on a crown-implantretention screw system of implant-supported crowns. Hexagon castable UCLA abutments were cast in Co-Cr alloy to fabricate 48 metallic crowns divided into four groups (n = 12). Group A: crowns did not present misfit; Groups B, C and D: crowns were fabricated with unilateral misfit of 50, 1...

1-methyl-2,4,5-trinitroimidazole (MTNI; 1) was reinvestigated and fully characterized as a promising candidate of new insensitive high explosives. Compound 1 was synthesized from the imidazole (2), via 5 step reactions. According to our preliminary sensitivity tests, 1 was almost as insensitive as TNT. The explosive performances, i.e. detonation velocity, and C-J pressure, were evaluated theore...

AIMS AND OBJECTIVES The aim of this study was to asses & compare the load transfer characteristics of Ball/O-ring and Bar/Clip attachment systems in implant supported overdentures using analog and finite element analysis models. METHODOLOGY For the analog part of the study, castable bar was used for the bar and clip attachment and a metallic housing with a rubber O-ring component was used for...

A hybrid denture is one that is fabricated over a metal framework and retained by screws threaded into the implants. The anterior part of a mandibular hybrid denture is fixed on implants while the posterior part of the denture is extended and cantilevered from implants. This article presents the fabrication of a mandibular implant retained hybrid prosthesis. A total of four implants were placed...

The purpose of the present study was to evaluate the relationships among three flexural strengths of recent dental ceramics using 3-point and 4-point bending tests and biaxial flexural test. Three brands of porcelain for veneering (d.SIGN, Supper porcelain AAA, Vintage Hallo), two injectable ceramics (Empress 2, OPC 3G), and one castable ceramic (Crys-Cera) were used. Twenty bar-shaped and 10 d...

High-quality alumina raw materials allow corundum-based brick and monolithics to perform the full potential of as a refractory material. Dense packing matrix submicron range reduction water demand castables can be facilitated by new family multimodal reactive alumina. Dispersing aluminas ensure uniform mixing dispersion setting adjustment additives. In this study, fine powder production was inv...
