Description
Plain Rim Lock Impression Tray Set of 6
Six plain impression trays cover the core adult sizes for many offices. This set gives you three uppers and three lowers, each with a solid body and a rim lock border.
Three uppers, three lowers
Inside you will find U2, U3 and U4 for the maxilla. You also get L2, L3 and L4 for the mandible. Since the numbers match top to bottom, you can grab a pair quickly when a patient needs both arches.
The rim lock explained
The border carries a raised rim that keys into the material. Because the walls have no holes, that rim and a coat of tray adhesive do the work of retention. So paint the adhesive inside and over the rim, then let it dry before you load. In return, a solid tray keeps the mix contained and the edges tidy.
Best fit for these practices
- Offices that need a compact starter set rather than a full range
- Satellite rooms with less storage
- Clinicians who like solid trays for elastomer work
- Teams that want a spare set for busy days
Choosing between U2, U3 and U4
Start with the middle size and try it in. If the flange presses on the tissue, move up one number. If it sits loose with too much space, move down. Also look at how far back it reaches before you commit.
Cleaning between patients
The set ships non-sterile. Therefore, clean and sterilize each tray before its first use. After a case, peel off the set material and scrub the adhesive away. Then put the six plain impression trays through your normal wash and autoclave cycle and reuse them.
Quality and where to find more
We set the specification, and each set goes through inspection in the United States. For material, we chose stainless that complies with ASTM F899. We also back these trays for three years against manufacturing defects when you use them as intended. For a holed version, see the perforated set of 6. Otherwise, look through our full tray and hollow ware line or check answers to common questions.
