Background: Imprelon® Biostar foils are new alternative tray material that has become increasingly popular because oftheir several advantages. Also, (Duran®) is another type of Biostar foils which is used in splint therapy. This study assessed some mechanical properties of these two types Biostar sheets in comparison with some types of acrylic resins used for construction of trays and splints. ...

background and aims. the purpose of this study was to evaluate initial force and force decay of commercially available elastomeric ligatures and elastomeric separators in active tieback state in a simulated oral environment. materials and methods. a total of 288 elastomeric ligatures and elastomeric separators from three manufacturers (dentaurum, rmo, 3m unitek) were stretched to 100% and 150% ...

objectives: this study aimed to assess the effect of storage time and temperature on dimensional stability of impressions made with cavex outline zinc oxide impression paste. materials and methods: a round stainless steel mold with five grooves (three horizontal and two vertical) was used in this in-vitro experimental study. cavex outline impression paste was prepared according to the manufactu...

Elastomeric proteins underlie the elasticity of natural adhesives, cell adhesion and muscle proteins. They also serve as structural materials with superb mechanical properties. Single molecule force spectroscopy has made it possible to directly probe the mechanical properties of elastomeric proteins at the single molecule level and revealed insights into the molecular design principles of elast...

conclusions within the limitations of this study, disinfectants were able to completely eliminate microorganisms carried by the alginate impressions. however, more efficient disinfection methods are needed to eliminate the risk of cross contamination by condensational silicone impressions. background dental impressions often carry microorganisms that may cause cross-infection from patients to d...

introdouction: infection control procedures are essential fordentists. oral and dental impressions can act as carriers of contaminants that can increase the risk of infections while being transferred from the laboratory to the dental office. therefore, the aim of this study was to evaluate the knowledge and practice of dentists regarding disinfection of impressions sent to the laboratory. mater...
