Affinity™ InFlex Maximum Support Tray Material

Affinity™ InFlex Maximum Support Tray Material

InFlex is the only support tray material designed for the dual-arch impression technique and specifically to prevent the impression distortion so commonly associated with this technique.


InFlex Maximum Support Tray Material combines an ideal flow to drive the light body into the sulcus without over-displacing it. Similar to a bite registration, InFlex becomes very rigid and supportive upon curing. This is very crucial when using a dual-arch impression tray.

  • InFlex is a rigid tray material designed specifically for the dual-arch impression technique.
  • InFlex has a low fluid viscosity, without being runny, to ensure Light Body is not overdisplaced away from the prep site, a common clinical problem with most tray materials that lowers accuracy.
  • InFlex cures to a very rigid 80 durometer, similar to a bite registration material. InFlex supports both metal and plastic dual-arch trays to eliminate impression distortion.
  • Very easy to extrude.
  • Ideal, seamless blend with all Affinity Light Body viscosities.
  • Available in 50mL cartridges, 120mL cartridges for chair-side dispensing with the PowerMix and 380mL MegaMix cartridges for automix dispensing

Full Quadrant Impression using Affinity InFlex, Affinity Light Body RF and Quad-Tray XL

Inflex Maximum Support Tray Material is loaded onto both sides of Quad-Tray XL
After syringing Affinity Light Body RF (Regular Flow) around the inlay preparation and implant site, the Quad-Tray XL encompasses the full quadrant.
Perforated buccal wall locks impression material to the tray
InFlex flows through the Quad-Tray XL’s slotted lingual and buccal walls to lock the impression material and tray together.
Notice how InFlex has displaced the Light Body without over-displacing it from the prep sites.
Precise detail is achieved every time.

With tissue management and hemostasis achieved (Tissue Goo Hemostatic Gel), the preparation is cleaned with Detail Pre-Impression Cleansing Gel to remove any residual debris and hemostatic agent ensuring complete polymerization of the Affinity InFlex VPS tray material and Affinity Light Body VPS material.
The Affinity Light Body impression material is placed after the Re-Cord #00 cord has been carefully removed, making sure to keep the tip submerged.
After InFlex is loaded sufficiently into the Quad-Tray Xtreme, the tray is placed immediately. The patient is asked to passively close. If no segmental bite registration has been taken prior to the impression, the patient may need to be guided into position.
While holding the tray firmly at the based of the handle, gently rock the impression material until it releases. Never torque the handle of the tray to prevent bending of the aluminum body.
The final impression showing excellent capture of the margins as well showing that the Light Body was not displaced by the hydraulics of the InFlex. This ensures a more accurate die and better fit of the final restoration.
Due to the accuracy of the impression, the final ceramic restoration fit beautifully with little adjustment required.

How is Affinity different from other impression materials?2019-05-07T15:46:24-04:00

Only Affinity uses branched resin chemistry for 3-dimensional cross-linking resulting in a higher tear strength, refined fillers, and an even distribution of surfactant. Other impression materials use linear resin chemistry with an uneven distribution of surfactant resulting in less accurate impressions that are more prone to tearing of the thin interproximal and sulcus fins.

I really like my light body from another brand. Can I use Affinity Heavy Body (or other Affinity Tray Materials) and my light body together?2019-05-07T15:47:55-04:00

Light and heavy body materials from another brand may be mixed but strict attention must be paid to the working and set times as they need to mimic or exceed Affinity’s.

How can I prevent air bubbles in my wash material?2019-05-07T15:48:11-04:00

Always keep the tip of the mixing tip fully immersed in the Light Body fully as it is syringed around the prep sites.

I’m having difficulty loading Affinity InFlex into Quad-Trays. Are there any tips that will help?2019-05-07T15:48:27-04:00

It is important to work quickly when loading Quad-Trays. Dispense Affinity InFlex in an S-pattern onto the non-prep side after running a bead of material around the periphery of the tray. Immediately turn the Quad-Tray over and repeat on the prep side.

Affinity sets more quickly compared to what I was using before. What can I do?2019-05-07T15:48:40-04:00

If using Fast Set, switch to Affinity Regular Set impression material. Do not attempt to adjust the temperature of the material in order to slow down the set.


Chad Duplantis, DDS, FAGD
Affinity™ InFlex is a very unique material that has several desirable properties: low viscosity to prevent tissue displacement, it’s also rigid enough to prevent pouring distortion due to its 80 durometer reading. This material has been extremely beneficial for both my dual-arch and my full arch implant impressions.

The combination of Quad-Tray Xtreme with Affinity InFlex and Light Body XL impression material provides me with a “one-two punch” to achieve “knock-out” single tooth impressions. This combination is so fast and easy. I prefer it to my intraoral scanner.

– Dr. Elliot Mechanic

Affinity is a unique impression material designed for each procedure. InFlex and Quad-Tray make for an unbeatable combination for “everyday” quadrant crown and bridge impressions.
