Dental Impression Tray
A dental impression tray is a convenient dental accessory made to hold impression material in the mouth and keep it at that till the material sets. The tray allows dental surgeons and professionals to get an accurate negative impression of a patient’s oral structures. A proper dental impression covers the arches, keeps the shape during impression taking, and retains the position.

What factors should be considered before buying a Dental Impression Tray?
The following factors should be kept in mind before making an online purchase:
- Construction: Dental instrument manufacturers use high-grade surgical stainless steel to construct dental impression trays. These trays allow professionals to reuse the accessory repeatedly without the risk of rust. You can also order disposable plastic trays, which are for one-time use.
- Size Charting: Every tray has a different size. Always choose dental trays for impressions that fit well into the arches and natural tooth structure.
- Arch: The right dental tray is the one that is appropriate to either maxillary or mandibular configuration.
- Structure: The structural integrity of the dental impression trays should be inflexible and rigid so that the material can easily be carried and impressed.
