Impression Tray(s) – Dental Arch Trays for Accurate Alginate & Silicone Impressions

Impression Trays are essential dental devices used to hold impression material (alginate, silicone, PVS, or polyether) for creating accurate replicas of a patient’s dental arches. They are designed to support material flow, ensure stability during seating, and capture precise anatomical details of the teeth, gums, and surrounding tissues.

Used daily in general dentistry, orthodontics, prosthodontics, crown & bridge work, denture fabrication, and oral surgery, impression trays are available in multiple designs, materials, and sizes.

Impression trays are manufactured in metal (stainless steel) or autoclavable plastic. They come in upper and lower arch designs, each anatomically contoured to fit comfortably in the patient’s mouth.

Models include:

• Perforated trays (holes for mechanical retention)

• Solid trays (smooth walls for high-viscosity materials)

• Edentulous trays (for patients without teeth)

• Quadrant and triple trays (for limited-area impressions)
