This Posterior dual-arch tray has a wide arch, is as rigid as a steel bar, and narrows to the back of the mouth. Note the retention tracks along the occlusal plane, which allow the tray to function without tray adhesive.
The Anterior Dual Arch Tray has a facial midline positioner. These alignment 'sticks' are included with each tray, For single units they may not be required, but with multiple units the alignment sticks accurately convey the facial midlines to the technician.
The Anterior Dual Arch Tray modeling the position of the alignment sticks; in an actual procedure the sticks are held to the measured facial mid-lines with impression material.
In an extensive study done in 2014 by an Utah-based independent dental products evaluation organization* , the Harmony Dual Arch Trays were highly rated. More than 60% of the evaluators would incorporated them into their practice, with 73% rating them excellent and worthy of recommendation to colleagues.
Now, in just one simple step, you can capture the prepared teeth, the opposing arch, and the bite registration using the Harmony Anterior Tray. The
Harmony Anterior is an anterior tray and a facial plane relator, identifying the patient’s midline, in one device. The Harmony Anterior Dual Arch
Tray can be used without alignment sticks for single units, or with them for multiple units. No more slanted crowns or veneers.
The narrow stainless steel bar at the back is only 2.6 mm in diameter, preventing tuberosity impingement, while still giving it rigidity equal or better than any other disposable Posterior dual arch tray.
The Harmony Posterior Tray narrows to the back of the mouth, and the side walls are low. Other trays stay the same width, and even become larger in places towards the back of the mouth. This is the cause of tuberosity impingement and poor bite registration.
The steel bar in the Harmony Posterior Tray offers superior rigidity, which is a large factor avoiding distortion of the impression.
