Perforated Retention Rim Impression Trays

Description

Perforated Retention Rim Impression Trays

Our perforated retention rim tray pairs rows of holes with a deeper rim along the border. The catalogue calls it an impression tray with retention rim. Its style codes are U1, U4 and U7 for uppers and L20, L21 and L22 for lowers.

What the Deeper Rim Does

The rim forms a wall around the edge of the tray. So the material has more to grip at the border, and the margins stay supported as you remove the tray. Meanwhile, the perforations anchor the body of the impression.

Six Options to Choose From

Pick an upper or lower retention rim tray in size L, M or S. Here is how each pair compares:

• Large: upper 81×67 mm, lower 81×60 mm
• Medium: upper 71×64 mm, lower 79×57 mm
• Small: upper 70×57 mm, lower 76×54 mm

Good Uses for This Style

Use it for alginate study models, opposing arches or routine records. Because the rim adds depth, it can also help when you want a thicker layer at the border.

Before You Load

Try the tray in first. Check that the rim does not press into the vestibule and that the heels cover the last teeth. Then mix your material.

Holes That Stay Clear

After use, rinse the tray before alginate dries. Next, an ultrasonic bath clears the perforations so the next impression grips just as well.

This perforated retention rim tray ships non-sterile, and it stays reusable through many wash and autoclave rounds. Built to our own drawing, it passes a hands-on check in the United States before dispatch. Its stainless grade is listed under ASTM F899. Every perforated retention tray carries three years against manufacturing defects, retention bead included. In a clinic that wants no holes, the solid retention rim version comes in the same sizes.
