3M ESPE has released the Directed Flow Impression Tray, a truly unique, innovative impression tray designed to negate the need for tray adhesive, simplifying both preliminary and final impressions while delivering outstanding quality, accurate results and easy handling.
The new, single-use trays are rigid and offer excellent stability and accurate results when making preliminary impressions of temporary restorations, study models, opposing dentition, fabrication of trays (e.g. bleaching, mouthguards) and full arch final impressions for most crown and bridge procedures.
The revolutionary self-retentive fleece strip holds the impression material securely in the tray, eliminating any need for a tray adhesive. This means fewer handling steps, saving an estimated five minutes per procedure as well as no more unpleasant odour or mess from a tray adhesive. In addition, the retentive fleece features striations that act as a barrier to avoid tooth/tray contact and occlusal flat-spots.
The shape of the tray, with its built in spoilers, actually directs the flow of the impression material to significantly reduce the formation of flow defects by directing the impression material back against the buccal and lingual tooth surfaces.
Generated utilising CAD/CAM technology, a significant innovation for impression trays, the 3M ESPE Directed Flow impression tray was designed based on numerous anatomical studies and measurements. Thus, the tray requires only three sizes for upper and lower impressions, allowing for an optimal fit. A built-in reservoir reduces gagging for improved patient comfort, and with a single-use tray, there is no need to disinfect and clean, as with metal trays.
Further, the Directed Flow impression tray can be customised if necessary.
