Harmony Anterior: The world's first biodegradable dual-arch tray. Now in just one simple step you can capture the prepared teeth, the opposing arch, the bite registration as well as the facial midlines. It's an anterior tray and a facial plane relator in one device. Use without alignment sticks for single units, or with alignment sticks for multiple units. Harmony Posterior: Harmony's green technology is also available in a posterior design. The narrow stainless steel bar at the back is only 2.6mm in diameter, preventing tuberosity impingement, while still giving it rigidity surpassing all other dual-arch trays.
