Affinity™ Crystal Matrix Impression Material

Affinity Crystal is an advanced silicone matrix material you can light-cure through. Designed for easy fabrication of temporary veneers, Affinity Crystal is the only matrix material to utilize branched resin chemistry, resulting in greater procedural efficiency, higher tear strength, and the most predictable results for accurate provisional restorations.

AffinityCrystal matrix impression material is ultra-durable, and easy to place. Its transparency allows the clinician to control flash formation, both interproximal and gingival, by visually verifying seating and adaptation of the filled matrix. Voids and air bubbles in the temporary composite material can also be detected easily.

With a working time of 45 seconds and intraoral cure time that can be as short as 90 seconds (for a maximum procedure time of only 2:15 minutes), Affinity Crystal is far more efficient and accurate than traditional procedures using putty, alginate, and vacuum splints.

What are the working and set times of both Affinity regular set viscosities and fast set?2019-05-07T15:45:35-04:00

The working time of Affinity Regular Set material is 1:45 mins with a setting time of 2:30 mins.
Affinity Fast Set materials have a working time of 1:10 mins and a set time of 1:45 mins.

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.


The Best of the Bests!

I use crystal for all my mock ups. to inject composites after the wax up and there is nothing better.

 Our choice for light cured indirect bonding

Affinity Crystal Vinyl Polysiloxane is our choice for light cured indirect bonding. It is viscous enough so that it doesn’t flow under the bracket pads but still captures the brackets enough for precise positioning. It works well with our two part tray system for orthodontic brackets or with the single tray system we use for bonded lingual retainers. It comes off in one piece and doesn’t get stuck behind the tie wings or in the slots.
