Affinity™ Crystal is a water-clear, silicone matrix material designed for easy fabrication of provisional veneers. Affinity Crystal flows effortlessly into the embrasure areas, capturing extreme detail to create an accurate, clear matrix through which you can light-cure provisional material.
Affinity Crystal is part of the Affinity line of impression materials that combine a unique branched resin, more refined filler and even distribution of surfactant for enhanced accuracy. The result is greater procedural efficiency, higher tear strength, and the most predictable results for accurate provisional restorations.
Affinity Crystal’s 100% transparency allows the clinician to control flash formation, both interproximal and gingival, by visually verifying seating and adaptation of the filled matrix, thereby decreasing finishing time. 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 than traditional procedures using putty, alginate, and vacuum splints. Other features and benefits include:
- Advanced silicone matrix material you can light-cure through
- Prevents formation of interproximal and gingival flash
- Transparent formula facilitates proper seating and detection of voids and air bubbles
- Outstanding durability and tear strength
- Ideal working and setting times
- More efficient than traditional procedures using putty, alginate, and vacuum splints.
Indications for Use
Affinity Crystal is an advanced silicone matrix material designed for easy fabrication of temporary veneers and for the orthodontic Indirect Bonding Procedure.
Two mottled centrals with a diastema to be treated with porcelain veneers. Length of #8 to be increased with electrosurgery.
Fill a clear, non-perforated tray with Affinity Crystal.
Place tray and Affinity Crystal on diagnostic stone model and leave to cure (1:30 minutes).
Affinity Crystal trimmed on labial 5mm past gingival margin and lingually 1mm past anticipated lingual cavo-surface margin.
Syringe a thixotropic flowable material directly into the facial/internal aspect of the clear matrix. Start at the incisal edge, working toward the cervical.
Spot etch preps for retention. If there are more than two preps, spot etch alternate teeth.
Gently place the matrix intraorally and adapt with both light incisal and labial pressure. Light-cure each preparation from the facial side of the matrix for 5 seconds per preparation. Remove the matrix.
Flash will be minimal, any excess will flow over the cervical margin and can be easily removed with a bladed instrument. Light-cure again for 20 seconds/unit.
Temporary veneers shown with excess flash peeled off.
Final temporary veneers.
After placing brackets on a model and light-cure for 3 seconds with a Valo curing light in Xtra power mode, place Affinity Crystal clear impression material on labial, buccal, occlusal and palatal surfaces.
After Affinity Crystal is set, place model in a bowl of warm water for 15-20 minutes, this allows the separator to release the brackets from the model.
Using Ortho Prophy SA-85 (Danville) and blast the undersurface of the brackets to clean off excess separator or stone.
"Affinity Crystal is easy to trim and duplicates the patient’s dentition and embrasure areas precisely. It’s my matrix material of choice for veneers because it provides enduring water-clear transparency, without turning yellow."

"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."

Q: How is Affinity different from other impression materials?
A: 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.
