Panasil (2017 Preferred Product)

Consultants’ Comments

  • “I like the viscosity of the light body–little to no voids, bubbles or drags.”
  • “The heavy-bodied material extruded easily compared with most heavy-bodied materials. The light- and heavy-bodied materials always blended together seamlessly and the heavy-bodied material provided excellent detail without drag.”
  • “Easy to use, fast setting, good color contrast and good flow.”
  • “The setting times seemed to be slower than indicated in the instructions.”
  • “Put light and x-light materials in small syringes.”

Description

Panasil is a line of addition-curing silicones (VPS) impression materials with hydrophilic properties. A variety of six viscosities and two set times exists. Panasil can be used for one- or two-step crown-and-bridge impression techniques as well as denture and reline impressions. Three viscosities of the fast-set material were evaluated: Panasil tray fast and Panasil initial contact light fast and x-light fast. Panasil tray fast is a heavy-bodied material for use in the tray and for functional impressions. Panasil initial contact fast is a syringeable impression material for capturing fine detail around prepared teeth and soft tissue. Panasil initial contact fast has a working time of one minute with an intraoral setting time of two minutes; total setting time is three minutes. Panasil initial contact light fast is available in 50-ml automix cartridges. Panasil tray fast is also available in cartridge and foil bags for use in an automatic mixer. Each box contains two 50 ml cartridges of material with 6 or 12 mixing tips. Panasil was used by 21 consultants in 325 cases. Panasil received a 96% clinical rating.

Viscosity of Light/X-Light/Tray Material

Eighty-one percent of consultants used a one-step technique and 67% preferred the heavy-body/light-body combination. The light/x-light material blends seamlessly with the tray material.

Working/Setting Time

Working times received a high rating. Consultants observed that setting times seemed to be slower than indicated in the instructions.

Ease of Removal from Mouth

Ease of removal of impressions from the mouth received a good rating.

Taste/Scent

Taste and scent received good ratings.

Tear Resistance

Overall Rating

Forty-three percent of consultants reported that Panasil was better, whereas 57% reported it was the same as their current impression material. Seventy-one percent would switch and 95% would recommend it.

Clinical Tips

  • Blow air on the preparation after syringing the light body material to push the material below the margins–excellent detail without any air bubbles and voids.
  • Wait a little bit longer than the recommended setting time to ensure complete set.
