A dental impression tray made of plastic is proposed to be used in a disposable manner. The dental impression tray includes a tray body for securely holding a mold material, and a handle which is separately prepared and adapted to be connected with the tray body when in use. The handle is separated from the frame body while in storage, so that they can be separately stacked with less bulkiness in storage. The tray body and the handle are provided with a locking means which can securely connect the tray body and the handle into one unit.
