The effect of a disinfectant on the bond strength between a disinfected wash impression and a subsequent wash application was also evaluated to simulate perfecting a disinfected final impression clinically. Vinyl polysiloxane (putty or wash) and polyether (wash only) impression materials were placed in...
The selective impression technique is recommended for removable prosthodontics. However, the viscoelastic rheological properties of impression materials, particularly the time-dependent viscoelastic changes in impression material immediately after tray seating, are unknown. The objective of this study is to cla...

SummaryDental elastomeric impression materials of different consistencies, representing addition and condensation silicones, polysulphides and a polyether, were studied to determine their mechanical properties in terms of tearing energy, tensile properties and modulus determined at high strain rates. Whilst the...
The wettability of impression material affects the number or volume of air bubbles generated during the pouring of gypsum casts. This study was done to determine the effect of various commercial disinfectant solutions on the wettability of elastomeric impression materials. The technique of measuring adva...
