<p>Disclosed is a dental impression tray realized such that the width of the dental impression tray can be adjusted to match different sizes of patient's dental arches and the adjusted width of the dental impression tray can be stably maintained during the procedure of obtaining an impression of teeth of a patient. The dental impression tray includes first and second container parts to contain an impression material therein, the container parts being shaped to correspond to a patient's dental arch and being separated from each other; a pivot part to pivot the first and second container parts together such that the container parts can be rotated around the pivot part, thus adjusting the width between the container parts; and a handle part extending from the container parts and being gripped and handled by an operator while adjusting the width between the container parts, and being provided with a locking means for stably locking the first and second container parts in positions corresponding to an adjusted width. Thus, the present invention can adjust the width of the dental impression tray to match sizes of patient's dental arches which are different from each other by the dental cavity and teeth of a patient, so that the tray can be adapted to all of the patients. Furthermore, the adjusted width of the tray can be stably maintained during the procedure of obtaining an impression of teeth of a patient, so that a correct dental impression can be quickly obtained.</p> |
