Third generation hydroactive chemistry is specifically designed for dual-arch closed-bite techniques.
AFFINITY InFlex impression material from Clinician?s Choice is specifically formulated for use with dual-arch trays. AFFINITY InFlex is used to eliminate the risk of distortion associated with the deflection and rebound of these flexible trays and the distortion created when pouring up these impressions in the laboratory when using flexible impression materials. Distortion leads to a wide range of clinical problems, including tight fitting crowns, marginal gaps, contact problems, and excess time required for occlusal adjustments. AFFINITY InFlex exhibits the high durometer of a bite registration material formula combined with the support and working/set times (regular and fast) of a tray material. AFFINITY InFlex can provide more rigidity than a putty or a heavy body, so it is suitable for implant pick-ups and transfers as well.
A Feature-Rich Family
As a member of the AFFINITY Hydroactive impression material family, AFFINITY InFlex offers the benefits of Clinician?s Choice?s proprietary 3rd generation chemistry. Like other AFFINITY materials, AFFINITY InFlex incorporates a hydroactive surfactant grafted to a branched resin, which is distributed throughout the material for excellent accuracy. The grafting ensures a complete cure, high strength, and dimensional stability.
Other features include enhanced hydrophilicity for excellent performance in the presence of moisture, especially with subgingival preparations; and matched fluid states between the tray and wash materials to better capture the preparation site by not over-displacing the light body.
Faster Procedure Time
Regardless of how much working time is used, AFFINITY InFlex?s set time is always less than 3 minutes because the working time is independent from the set time. That means the clinician can use as much of the 1 minute 45 second working time as necessary, place the material intraorally, and then set the timer for 3 minutes?the unused working time does not have to be added to the set time. In addition to lessening patient discomfort and the possibility of gagging, a faster intraoral set time helps prevent distortion, as there is less opportunity for tray/material disruption caused by patient swallowing or other movement.
Clinician, educator, and author Dr. Len Boksman thinks AFFINITY InFlex is the ideal material for the dual-arch closed-bite impression. ?In my office, for dual-arch impressions, I use AFFINITY InFlex impression material, which I?ve found has a very low strain in compression (that is, high stiffness) while still demonstrating the flow necessary to give reproduction of detail,? Dr. Boksman noted.
Gregg Tousignant, CDT, concurs. ?Dual-arch trays require a high durometer, and inflexible heavy body material such as InFlex from Clinician?s Choice to provide the support and resistance to distortion required for these types of trays,? he noted. ?Due to its chemistry, this viscosity has similar flow characteristics to light body materials, but has a setting hardness higher than that of a heavy body or putty material.?
