چکیده
The results of a comparative analysis dental glass ionomer cements are compared: "AHfil +" (AHL, United Kingdom), "Ketac Molar Easymix" (3M ESPE, USA), "Fuji IX GP" (GC, Japan), "ProGlass Nine" (Silmet , Israel), "Polyacrylin" (TechnoDent, Russia), "Cemion" (VladMiVa, "Kemfil" (StomaDent, Russia) and "Glassin Rest" (Omega-Dent, in terms working time, hardening strength compression, radiopacity, microstructure chemical composition. It is shown that the main component powders these GICs crushed calcium ("Kemfil"), strontium ("AHfil +", GP"), calcium-strontium ("ProGlass Nine", Rest") lanthanum-calcium aluminofluorosilicate ("Ketac Easymix"). All them contain phosphorus. Differences powder granulometric composition indicate difference technology grinding during their production. time studied from 1 to 3.5 minutes. requirements GOST 31578-2012 ISO 9917-1:2007 do not correspond (36 ± 3 MPa), (68±6 MPa) strength, time. has highest (201 33 rest GIC - 142-169 MPa. GICs, with exception non-radiopacity have radiopacity corresponding mm aluminum. According tests, Easymix", GP", recommended for clinical use by dentists

Sintering behaviour of composite materials borosilicate glass-ZrO2 fibre composite materials
The characteristics and properties of mixtures of a borosilicate glass and ZrO2 fibres obtained from compacts isothermally sintered are presented. Three different particle sizes of glass powder and different sintering temperatures and times have been used to reveal the influence of the specific surface area and the glass matrix viscosity on sintering. The fundamental developed aspects are the s...
متن کاملRadiopacity of glass-ionomer/composite resin hybrid materials.
This study visually compared the radiopacity of seven restorative materials (3 resin-modified glass-ionomer cements, 3 polyacid-modified composite resins, and 1 conventional glass-ionomer cement) to a sound tooth structure sample, and an aluminium stepwedge. All hybrid materials were more radiopaque, except for one resin-modified glass-ionomer cement, than both the tooth structure and conventio...

This paper deals with the study of machinability of GFRP composite tubes of different fiber orientation angle vary from 30 to 90. Machining studies were carried out on an all geared lathe using three different cutting tools: namely Carbide (K-20), Cubic Boron Nitride (CBN) and Poly-Crystalline Diamond (PCD). Experiments were conducted based on the established Taguchi’s Design of Experiments (DO...
متن کاملComposite materials based on silk proteins
A number of animals have evolved to produce silk-based composite materials for a variety of task-specific applications. The review initially focuses on the composite structure of silk fibers produced naturally by silkworms and spiders, followed by the preparation and applications of man-made composite materials (including fibers, films, foams, gels and particulates) incorporating silk proteins ...
