Abrégé

An artificial tooth articulator of the present invention comprises: a pair of upper and lower table means that are detachably coupled to the central shafts of horizontally adjustable support stands in the centers of base and top plates and are adjusted to horizontally move forward, rearward, leftward, and rightward; and a pair of upper and lower tray jig means that are detachably coupled to the inner surfaces of the pair of upper and lower table means by magnetic forces, respectively, and support upper and lower trays, the intermaxillary relationship of which is adjusted in a patient's oral cavity, by means of press-fitting such that the upper and lower trays face each other. Accordingly, it is possible to accurately reproduce the intermaxillary (jaw interval) relationship of an individual patient in the articulator by a simple operation. In addition, the upper and lower trays for manufacturing dentures, the casts (impressions) of which are taken from a patient, can be simply attached to the predetermined positions by magnetic forces, thereby accurately and rapidly performing the horizontal and vertical adjustment of the intermaxillary relationship.

Abrégé

The present invention relates to a false teeth structure capable of being arranged in bundles and, more specifically, provides false teeth in bundles by inserting and arranging a coupling protrusion (12) of each false tooth (10) into a rail groove (22) of a plate-shaped assembly jig (20) according to the dentition structure of the upper jaw and the lower jaw, and temporarily fixing the same by wax (30), and thus workability is excellent since the necessary size of a part, rather than a piece, is cut so as to be simply coupled in bundles to a base plate (50) after carrying out bending according to the dentition curved line structure of a patient when manufacturing dentures. Particularly, excellent functionality is provided since the height or contact point of each false tooth (10) can be simply adjusted.

Abrégé

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.
