I am big fan of fast-acting vinyl polysiloxane impression (VPS) materials with exacting detail, and Voco’s V-Posil materials, with a variety of viscosities, meet my criteria for accurate, fast, and easy impressions.
More "I have it—you want it!":
When using a putty-wash technique, I will use the V-Posil Putty Fast in combination with the V-Posil X-Light for an accurate full-arch pick-up of prepared teeth. With both materials, there is a 2-minute working time and a 2-minute setting time activated once placed in the patient’s mouth (thermally activated). There is a snap-set (although still easily removed from the patient’s mouth), which minimizes distortion, and since it has a very low contact angle, it acts like a polyether’s hydrophilic capability of taking impressions in the presence of crevicular fluids such as blood and saliva to yield a highly accurate impression. V-Posil materials have excellent tear strength and elastic recovery to ensure dimensional stability. The Putty Fast is hand-mixed and the Heavy Soft Fast is available as an automix bulk cartridge. Whether for full-arch impressions for crown and bridge, implants, partial denture prostheses, or even orthodontic aligner therapy, the putty-wash technique is made simpler by using V-Posil materials.
