• Ensure the tray is dry when you apply the adhesive 
• Use the air water to syringe to evaporate the monomer
• Tip: Ensure you have selected the appropriate adhesive for the final impression material! 

Bleed your PVS material before putting the applicator tip onto the impression gun

Note: PVS working times are as follows:

• 2 min working time
• 5 min setting time 

Note: Check the manufacturer’s instructions as brands may vary slightly in working / setting times

• “Butter” the impression material by using a spatula to smoothen any seams in the application of the PVS
• Ideally apply 1 mm thickness of PVS to the intaglio surface of the tray
• Coat the outside of tray thinly with <1mm of PVS

• Confirm full seating and support with bimanual pressure
  • Hold in the canine area
  • You should feel the tissue rests seated
  • Apply seating pressure on anterior palatal vault area
• Clinical Notes: 
  • You may use retractors at insertion of tray (but be sure to remove quickly after tray is placed)
  • Retract the lips and rotate tray into mouth
  • Perform passive border movement after seating the tray: Have the patient move lower jaw from side to side, grasp philtrum and pull it firmly upward, manually border mold cheeks, lips, and philtrum several times
  • Continue border molding in cycles of 20-30s until the initial set of impression material

• Note: PVS will not be shiny or sticky once it is ready to be removed
• Hold in place for full setting time (according to the manufacturer’s  instructions)

• Remove by breaking peripheral seal and releasing suction

• Place adhesive to the area to be relined
• Use small yellow PVS tip 
• Apply to the small area of the void 
• Adapt to the area of concern
