Dental impression tray with impression material retainer

摘要

A dental impression tray comprises a trough for receiving dental impression material and at least one retainer on at least a portion of an inner surface of the trough. The retainer comprises a plurality of anchoring elements, each of which comprises a first end, a second end, and an arc between the first and second ends. The first and second ends of the anchoring elements are connected to the inner surface of the trough, and the arcs project from the inner surface of the trough. The loop material of a hook and loop mechanical fastener is a particularly useful retainer.
