An upper and lower tray apparatus for manufacturing dentures according to the present invention comprises: upper and lower main trays (10a), (10b) inserted in the oral cavity of a patient so as to surround the upper and lower gums; upper and lower auxiliary trays (20a), (20b) inserted into a portion of the upper main tray (10a) and the lower main tray (10b) where occlusion takes place by the teeth coming into mutual contact, so as to be coupled or separated therefrom; and a tray control means (30), connected to the center portion between the upper main tray (10a) and the lower main tray (10b), for individually controlling the levelness and the height of the upper and lower main trays (10a) (10b) with respect to a cone die in the oral cavity of the patient to make the gums comfortable. Therefore, the upper and lower tray apparatus for manufacturing the dentures is distinctly different from existing techniques in terms of measuring a vertical distance between upper and lower jawbones and the movement path of the lower jawbone while taking a dental impression, and immediately aligning artificial teeth thereafter, during a patient's initial visit to a clinic, thereby enabling immediate confirmation of performance inside the oral cavity of the patient. Also, the upper and lower tray apparatus for manufacturing the dentures has the advantage of enabling the dentures, which are functionally and aesthetically completed in a revolutionary denture manufacturing period of five to six days, to accurately function in the oral cavity of the patient. |
