They are constructed from high-quality, rigid plastic that maintains its shape under pressure, ensuring the impression material is evenly supported and accurately captures the fine detail of the patient's dentition and soft tissues. A key feature is the perforated design, which consists of numerous small holes distributed across the tray surface.\u003cbr\u003e\u003cbr\u003eThese perforations allow the impression material (such as alginate or silicone) to flow through and securely lock itself into the tray upon setting. This mechanical locking mechanism significantly improves the retention of the impression material, minimizing the risk of the material separating from the tray during removal, which can lead to distorted or unusable impressions. Being made of plastic, these trays are disposable, promoting excellent infection control by eliminating the need for instrument sterilization between patients.\u003cbr\u003e\u003cbr\u003eThe medium size is one of the most frequently used sizes in general dentistry.
