Polyvinyl siloxane (PVS), also called poly-vinyl siloxane, vinyl polysiloxane (VPS), or vinylpolysiloxane, is an addition-reaction silicone elastomer (an addition silicone).

What is dental putty?
Lab putty is the dental material’s version of baseball’s utility player. In the lab, it can be used for a variety of applications like restorative space analysis, as a matrix for provisional fabrication or as a guide for the fabrication of definitive restorations.
What is polyvinyl siloxane used for?
Polyvinyl siloxanes have applications in fixed prosthodontics, operative dentistry, removable prosthodontics and implant dentistry.
How can I make my dental putty soft again?
Knead your putty in a bowl of hot water to get a very soft consistency. Fill a large bowl halfway with hot water so you can soak your putty. Place your putty in the water and begin folding and squeezing it with your hands. Continue kneading it in the water until it feels softer and easier to play with.
What is dental impression material made of?
In order to make a dental impression, a thick liquid material, such as alginate or polyvinylsiloxane, is dispensed into an impression tray that is shaped like a U in order to properly fit into a mouth. Alginate is found within the cell walls of brown seaweeds.
How long does it take for dental putty to harden?
Step 5: watch the clock. The putty should harden a bit before you remove your teeth, and that takes time. Remove the trays too early, and you won’t have a firm impression. Leave the putty on too long, and it’s hard to remove. Set a timer for 3.5 minutes.
Is siloxane toxic?
Generally, siloxanes (silicones) are well tolerated by the human organism, and therefore they are an integral part of innovative methods of treatment, health care and nursing. They are commonly regarded as non-toxic to humans and the environment, or toxic to a very small extend.
What is siloxane polymer?
Siloxanes are polymeric organic silicones that comprise a backbone of alternating silicon-oxygen [Si-O] units with organic side chains attached to each silicon atom.
What dissolves polyvinyl siloxane?
Polysiloxanes (if linear!) can be dissolved in non-polar solvents as hetane, toluene, benzene, chlorforom etc. If it is a rubber, however, it will only swell bot will not dissolve. Low moelcularr siloxanes can de dissolved even form rubbers.
Why does Silly Putty get sticky?
Silly Putty’s unusual flow characteristics are due to the ingredient polydimethylsiloxane (PDMS), a viscoelastic substance. Viscoelasticity is a type of non-Newtonian flow, characterizing material that acts as a viscous liquid over a long time period but as an elastic solid over a short time period.
Can you reuse Putty?
Microwave the Putty until it is soft and pliable. Allow Putty to come to a comfortable handling temperature, then press the putty onto the object you wish to mold, or push the object into the putty. Allow the Reuse- a-Mold to cool back to room temperature.
What is silicone dentistry?
Silicone, being a more elastic material, allows for more uses for dentists than alginate. Other uses for silicones include: reproductions of fractured teeth, through impression taking procedures, it also serves as a recording material for occlusal relationships due to its precision and dimensional stability.
What is putty wash?
The putty-wash technique is commonly used in making impressions with silicone elastomers. A technique is presented ensuring exact reseating of the putty impression tray and creation of a uniform wash space, which are essential for accurate results.
