That’s why Centrix Access Impression materials feature no-compromise VPS formulas that ensure you of successful results, time after time. Trust Access Impression materials to deliver exacting performance in all crown and bridge cases. Choose from our complete line of ADA-standard viscosities and impression accessories, which are patient-friendly, odor-free and taste-free. Made in the USA.
- Access GOLD® low viscosity wash material, syringes easily into sulcus and around prep through Access Impression tips. High contrast color makes it easy to see margins and verify all margins have been captured.
- Access MONOPHASE® is a non-slumping, medium body tray material for one-step, impressioning techniques. It remains in place while loading into both sides of dual arch trays and helps stabilize the tray, preventing distortion and rebound. Syringeable through Access Impression tips. Contains hydrophilic additives for higher accuracy and low contact angle.
- Access HEAVY® is a non-slumping, heavy body tray material. It remains in place while loading both sides of dual arch trays; stabilizes tray and prevents distortion and rebound.

How To's
NOTE: The adhesive does not always secure sufficient adhesion to trays made of other plastic materials or individual trays made of base plates. A polyether adhesive must be used for polyether impression materials.
Instructions for Use:
- Apply a thin layer of Access Tray Adhesive to the tray using the applicator brush.
- Allow to dry for at least 3 minutes.
- Load the tray with impression material and take the impression.
ACCESS VPS HOW-TO:
ACCESS IMPRESSION MATERIALS (VPS – VINYL POLYSILOXANE)
Access Impression Materials are addition reaction silicones which offer excellent physical and dimensional properties. Highly accurate and stable, Access impressions may be poured immediately or up to two (2) weeks after the impression is made. The material is odorless and tasteless, and may be soaked in common disinfecting solutions without distortion. Special hydrophilic surfactants have been added to Access Impression Materials to allow them to be highly wet table in a moist environment. Any of the viscosities will chemically adhere to another viscosity, permitting a wide range of possible techniques.
APPLICATION
Note: For faster procedures, it is advisable to use two (2) mixing dispensers.
Always apply a thin layer of Access Impression Material Tray Adhesive to a clean, dry impression tray. Allow to air dry for five (5) minutes before using. Contact with latex gloves, hemostatic agents, hand lotions, eugenol or sulphur compounds may interfere with the setting properties of Access Impression Materials.
TRAY / SYRINGE TECHNIQUE:
- Express Access Impression Material into a prepared tray, pre-coated with adhesive. Access Heavy, Access Monophase or Access Purple may be selected, depending on the application.
- Inject Access Gold low-viscosity or Access Monophase directly into a clean, dry, retracted sulcus preparation, using an Access intra oral needle tip (REF 290017).
- Seat the loaded tray into the mouth — allow to remain stable until set.
PUTTY / WASH TECHNIQUE: ONE STEP
Note: Do not mix putty with latex gloved hands!
- Remove equal amounts of Base and Catalyst from the jars using the supplied color coded scoops.
- Mix by kneading together for 30 seconds until no streaks are visible.
- Shape to fit into the desired tray, which has been pre-treated with adhesive.
- Place Access Gold low viscosity into an automix syringe and inject directly into a clean, dry, retracted sulcus preparation, using an Access intra oral needle tip (REF 290017).
- Seat the loaded tray into the mouth; allow to remain stable until set.
PUTTY / WASH TECHNIQUE: TWO STEPS
Note: Do not mix putty with latex gloved hands!
- Remove equal amounts of Base and Catalyst from the jars using the supplied color code scoops.
- Mix by kneading together for 30 seconds until no streaks are visible.
- Shape to fit into the desired tray, which has been pre-treated with adhesive.
- Place loaded tray in patients’ mouth – allow to remain stable until set.
- With a surgical rongeurs or coarse grit acrylic bur, remove all interdental flash and/or undercuts. Relieve area to be prepared.
- Place Access Gold low viscosity impression material in an automix syringe and inject directly into a clean, dry, retracted sulcus preparation using an Access intra oral needle tip (REF 290017).
- Seat the loaded tray into the mouth — allow to remain stable until set.

FAQs
Yes. You can use Access Blue in a tray with a wash. A wash in this case is a low viscosity VPS material like Access Gold.
If you are making 3 unit impressions, expect to get 50 to 75 from one finished goods. (2-3 finger full worth of materials each)
If you are making full mouth impressions, expect to get 25 from one finished goods. (full scoops each)
The scoops VERY generously use the materials, and would be overkill for a 3 unit impression.
The Access VPS impression materials uses 1:1 automix nozzles. The internal diameter is 6.5mm; it has 11 elements; and a straight end. The hub is green (also called teal) and the mixing element is natural or clear.
A distortion can take place in a Putty/Wash impression technique when the user takes the putty impression PRIOR to placing the Access Gold or similar wash VPS material. The removal of the set Putty causes the distortion, which may be called out by the lab. It is better to place both materials at the same time, which is technique sensitive. Or change to a Heavy/Wash technique, using Access Gold for the Wash and Access Purple, Heavy or Monophase for the Heavy VPS material.
No, they all are radiolucent.
