Take 1™ Advanced™

Impression Materials

VPS Impression Material

  • Outstanding tear strength and elongation. Strong, flexible impression material stretches around undercuts without tearing or distorting.
  • Hydrophilic dental wash material. Displaces intraoral fluids to produce impressions with great detail and no voids or gaps.
  • Excellent dimensional stability. Impression will not distort due to dimensional change or temporary deformation.
  • Widest selection of viscosities, set times and delivery methods. Helps overcome common difficulties in impression taking, and matches doctor preference.

Take 1 Advanced vinylpolysiloxane (VPS) impression material employs Kerr's long history of expertise in developing high-performance impression materials, along with recent technological advancements, to deliver a VPS impression material with the optimum combination of physical properties: strength, elasticity, dimensional stability and the ability to register detail in any environment. Furthermore, Take 1 Advanced comes in the widest selection of set times, delivery systems and consistencies available on the market today - so you always have the perfect combination of mechanical properties in a material that feels like it was designed just for your technique preferences.

Troubleshooting Guide


Evidence Cause Solution

Premature Set


  • Abrupt change from heavy to light-body material
  • Muted detail around margin
  • Set time of wash/tray material not synched
  • Exceeded working time of material
  • Begin mix of heavy and light viscosity concurrently
  • Verify set times for heavy and light viscosities match
  • Observe working time of materials

Deformation/Dimensional Change


  • Crowns too tall/short
  • Open contacts
  • Crown will not seat
  • Insufficient mix of material
  • Impression removed too early
  • Tray movement after seating
  • Insufficient material elasticity
  • Fluid absorption during disinfection process
  • Verify material is adequately mixed before seating and completely set prior to removal
  • Use passive force to maintain tray position when using open-bite technique
  • Verify no tooth contact with tray sides or impingement in closed-bite technique
  • Choose material with adequate elasticity
  • Follow disinfection protocol carefully

Tearing at Margin


  • Visible tears at margin
  • Lack of flash extending apically around entire preparation
  • Material has insufficient tear strength
  • Presence of severe undercuts
  • Insufficient sulcular expansion
  • Use material with adequate tear strength
  • Consider blocking out undercuts, especially in cases with gingival recession
  • Ensure at least .5 mm sulcular expansion

Surface Inhibition or “Non-set”


  • Unset or mottled surface around preparation
  • Lack of detail
  • Shiny/wet appearance
  • Contamination due to latex gloves; direct contact with material or residue left on teeth
  • Contamination due to temporary materials or composite
  • Expired material or exceeded material shelf life
  • Use latex-free gloves when handling VPS material
  • Rinse preparation area thoroughly after using other restorative materials
  • Use automated mixing device to minimize exposure to contaminants
  • Do not use expired material

Poor model detail


  • Small bubbles/indentations in cast
  • Powdery cusps
  • Release of hydrogen gas from VPS impression after pouring cast
  • Tooth contact with mesh lining of closed-bite impression tray
  • Follow manufacturer instructions regarding any delays for pouring models after taking impression
  • Place cotton roll on contra-lateral side when using closed-bite trays to prevent direct tooth contact with tray; this prevents water from leaching through tray after cast has been poured

Voids in wash material


  • Visible voids in wash material around tooth preparation
  • Bubbles incorporated into material during mixing or loading syringe
  • Bubbles incorporated while syringing material intraorally
  • Use automix systems
  • Syringe material intraorally in continuous stream around each preparation; do not lift syringe tip from material

Insufficient or excessive compression


  • Insufficient: wash material flows away from preparation area
  • Excessive: wash material displaced from preparation area; “burn through”
• Insufficient compression of wash material from adjacent tooth/tray or heavy-body material
• Excessive compression of wash material due to high viscosity of tray material
  • Use tray viscosity material with greater compressive force, or use custom tray
  • Use tray material with lower viscosity to avoid displacing wash material

Incomplete margin


  • Voids or “jumps” on margin
  • Inadequate tissue management
  • Contamination from intraoral fluids
  • Insufficient compression of wash material
  • Use Expasyl™ retraction paste to open sulcus and help maintain dry field
  • Use hydrophilic wash material
  • Select tray viscosity with adequate compression

Tooth contact with trayimpression_illo10-100x100

  • Visible impingement
  • Incorrect size tray
  • Tray seating not aligned with dentition
  • Verify tray has enough room for 2 mm of impression material between tooth and tray walls
