Effects of preparation techniques on the porosity of acrylic cements.
We investigated four acrylic cement preparation techniques for their effects on cement porosity: hand mixing, pressurization in a pneumatic pistol, centrifugation, and vacuum mixing. All the techniques were tested on three types of cement with different viscosity characteristics. The best results were obtained with vacuum mixing using a newly designed experimental system, yielding porosity redu...
متن کاملDental cements: an overview.
pulpal health, waiting for gingival healing from periodontal and oral surgery, waiting for implants to integrate, and evaluating aesthetic and functional changes, to name a few. Some of the clinical requirements of provisional cements are: (1) good retention – it is desirable to have enough retention for long-term provisional cementation, yet not be so retentive that is difficult to remove the ...
متن کاملSurface roughness, porosity and wettability of gentamicin-loaded bone cements and their antibiotic release.
In this study, the release of gentamicin as a function of time was measured for six different gentamicin-loaded bone cements and related with the surface roughness, porosity and wettability of the cements. Initial release rates varied little between the six bone cements (CMW1, CMW3, CMW Endurance, CMW 2000, Palacos, and Palamed) and ranged from 8.6 to 14.1 microg/cm2/h. The total amounts of gen...
متن کاملPorosity prediction of calcium phosphate cements based on chemical composition.
The porosity of calcium phosphate cements has an impact on several important parameters, such as strength, resorbability and bioactivity. A model to predict the porosity for biomedical cements would hence be a useful tool. At the moment such a model only exists for Portland cements. The aim of this study was to develop and validate a first porosity prediction model for calcium phosphate cements...
متن کاملPorosity of resin cements and resin-modified glass-ionomers.
PURPOSE To quantify the internal free surface in various resin cements and glass-ionomer-based materials. MATERIALS AND METHODS Materials tested were Nexus fluid (NXF) and viscous (NXV), Vitremer (VTM), Fuji II LC (FII), Vitremer Luting Cement (VLC), Dyract (DYR) and Compoglass (COM). Samples (n=5) were made of each material between two microscopic glass slides under same weight. With a trans...
