The IM002A Disposable Plastic Dental Impression Tray is a single-use, pre-formed tray designed for taking accurate alginate (irreversible hydrocolloid) impressions. Its standardized design and disposability make it a hygienic and convenient choice for preliminary models.
Technical Specifications & Material Science: This tray is injection-molded from rigid, medical-grade polystyrene. The “IM002A” typically denotes a specific size and arch (e.g., a universal or adult-sized perforated tray for the maxillary arch). Perforations throughout the tray body are critical, as they provide mechanical retention for the alginate material, preventing it from separating from the tray upon removal from the mouth. The tray has an anatomically shaped vault and a deep peripheral border to capture the full sulcus depth. A handle provides control during insertion and removal.
Industry Standards & Compliance: Class I medical device. The plastic is non-toxic and biocompatible for short-term intraoral use.
Application Scenarios: Primarily for taking preliminary impressions for study models, diagnostic casts, orthodontic records, and the fabrication of custom acrylic trays or mouthguards. It is the standard tray used in dental schools and high-volume clinics for these purposes.
Usage Guidelines: Select the correct tray size (should extend 2-3mm beyond the last tooth in the arch). Mix alginate according to manufacturer instructions. Load the tray, smooth the surface, and seat it in the patient’s mouth. Hold steady until set. After removal and disinfection, the impression can be poured with plaster or stone. The tray is then discarded, eliminating the need for cleaning and disinfection.
Market Value Proposition: This product is the epitome of efficiency and infection control for preliminary impressions. It saves valuable assistant time spent cleaning metal trays and guarantees a pristine, undistorted tray for every impression. For distributors, the IM002A is a high-volume, essential consumable with predictable demand from every general and orthodontic practice.
