Dental Impression Trays
BusinessMed® Dental Impression Trays carry the impression material to the mouth and hold it while it sets, so the arch can be cast as a model. The range covers numbered full-arch trays for dentate arches, shallow full denture trays for edentulous ridges, and partial, quadrant and swivel trays for sectional impressions — upper and lower, perforated or solid, in stainless steel.
Types of dental impression trays
Full-arch trays (#0 to #6)
Regular dentate trays have a deep channel for the teeth and are numbered by size from #0 X-X-Large to #6 X-X-Small, each for the upper or lower arch: for example the #2 Large upper perforated tray and the #3 Medium lower solid tray.
Full denture trays
Edentulous trays are shallow and contoured for a ridge without teeth, in sizes #1 to #4 — such as the #1 X-Large full denture upper perforated tray and the #2 Large full denture lower perforated tray.
Partial, quadrant and swivel trays
Sectional trays cover part of an arch. Partial trays come upper or lower; quadrant trays are made in diagonal pairs, one tray serving the upper left and lower right or the lower left and upper right; the swivel tray turns on its handle so one tray takes upper or lower quadrants on either side. See also the partial upper perforated tray.
How to choose a dental impression tray
- Dentate or edentulous. A regular tray has room for the teeth; a full denture tray follows the ridge. A lower impression tray for teeth is deeper than the denture tray of the same number.
- Size. The number is the size: #0 X-X-Large is the widest, #6 X-X-Small the smallest; full denture trays run #1 to #4.
- Perforated or solid. Perforations let the set material lock into the tray, so elastic materials such as alginate generally go in perforated trays; solid trays suit materials held by tray adhesive.
- Full arch or sectional. Full-arch trays record the whole arch; partial, quadrant and swivel trays take one section for crown and bridge work.
What are dental impression trays used for?
Impression trays in dentistry take full-arch impressions of dentate upper and lower arches for study models; preliminary impressions of edentulous jaws for complete dentures, from which the study model and custom tray are made; and sectional impressions of a quadrant or partial arch for crown and bridge work.
