Check-Bite Triple Tray Anterior, Box of 50
From GC America website
“CHECK-BITE™ triple function, disposable trays assure accurate working impressions and counter impressions of the opposing arch, as well as a precise bite registration in one easy procedure. CHECK-BITE™ trays cover more than half the arch area, resulting in multiple bite registration points for more accurate articulation.
When poured and mounted on the articulator, CHECK-BITE™ impressions produce a pair of contemporary, separable models in true occlusal relationship.”
