Distortion is invisible. Unfortunately, it only becomes evident with it’s too late. That is, when a crown or bridge doesn’t fit correctly, or when excess occlusal adjustment is necessary. When this occurs, many dentists are quick to blame their labs, yet continue to use plastic impression trays that are prone to flexion and rebounding. Use of these flimsy trays means a continued waste of chair time with retakes and occlusal adjustments. For perfect impressions and flawless-fitting prostheses, a rigid metal impression tray, such as the Clinician’s Choice® second-generation QUAD-TRAY® Xtreme™, is critical. Plastic is Elastic
Plastic, by nature, flexes so you can’t expect a plastic tray not to flex. If a heavy body, flow resistant material is used, its hydraulics force the tray outward causing it to flex. Because of plastic’s natural memory, distortion results. Distortion also occurs during mouth insertion if the tray impinges on the palate, or, when your patient closes it can force an axial roll of the wall position. Additionally, when the tray is removed from the mouth, the plastic’s memory causes it to rebound, resulting in prosthetic misfits.
The QUAD-TRAY Xtreme is part of Clinician’s Choice system-specific product line-up developed to ensure optimal results. When used with AFFINITY Inflex Maximum Support Tray Material, which has been designed with high durometer stiffness, distortion is virtually eliminated, as the material essentially becomes part of the tray.
Like its best-selling forerunner, the QUAD-TRAY®, the new QUAD-TRAY Xtreme from Clinician’s Choice is made of dead-soft aluminum and is memory-free, meaning it will not flex during insertion or rebound upon removal. Because of its ultra-low sidewalls and wide arch design, QUAD-TRAY Xtreme will never impinge on your patient’s palate or interfere with arch structure. The tray’s arch width can be customized to individual arch size.
[New Design Enhancements
q 25% thinner distal bar better eliminates palatal impingement and distortion.
q Retention bars built into tray sidewalls for better retention of impression material.
q Shorter lingual wall better fits smaller mouths.
q Mesh attached to all sides of tray, narrowing material to form a secure "lock" to tray walls.
The QUAD-TRAY technique is clinically proven and used daily by top clinicians for consistently accurate, perfect impressions.
