BEST MODE FOR CARRYING OUT THE INVENTION A denture manufacturing apparatus according to the present invention provides an artificial tooth arranging device in a part of a ready-made articulator, for example, a pin hole of an incisal table for attaching an incisal pin (center pin). Once installed, the ready-made artificial teeth can be aligned using the artificial tooth aligner.

Preferably, the artificial tooth arrangement is configured to support the shift device (eg, shift plate) by a ball joint type assembly, for example, a universal joint type assembly including a free clamp and a side pin. A shift device (for example, a shift plate) is installed at the tip of a free clamp that can be freely set, and an artificial tooth mold is attached to the shift plate. Preferably, a shift plate is attached to the tip of the free clamp so as to be freely expandable and contractable, the artificial tooth mold is fixed to the shift plate, and the artificial tooth is arranged in the artificial tooth mold.

If necessary, a side pin may be used in place of the removed incisal pin to secure the occlusal height.

As the artificial tooth mold, various ready-made artificial teeth can be used. As for the front teeth, six front teeth can be collectively arranged on the upper and lower sides. As for molars, four molars can be collectively arranged on both upper and lower sides.

Various other embodiments of the present invention will be described.

In the artificial tooth aligner, a member for attaching to a ready-made articulator, for example, a free clamp or a side pin is installed, and a holding member (for example, a holder) for holding a shift plate at an end of the free clamp is installed. I do. This holding member is a mechanism that can move the shift plate in the front-rear direction.

When a side pin is used as a part of the means for supporting the shift plate, it is preferable to provide a member to be applied to the lower part of the upper bow of the articulator, thereby securing the occlusal height.

Further, by mounting the left and right sides of the artificial tooth arrangement device upside down, it is possible to cope with a south paw. What is necessary is just to rotate the free clamp and the stopper for holding the occlusal high diameter by 180 °.

The shift plate is used to set the position at which the artificial teeth are arranged. Preferably, a midline and a front tooth position reference line are provided on both front and back surfaces.

It is preferable to attach a magnet to a fixed portion of the artificial tooth mold installed on the shift plate.

The occlusal floor on the working gypsum model mounted on the articulator and the base surface of the artificial tooth mounted on the artificial tooth mold,
The artificial teeth can be fixed by flowing the dissolved wax. At this time, it is possible to fine-tune the curvature depending on the case.

The artificial tooth mold can be made of various materials, for example, rubber (silicone rubber or the like), metal, synthetic resin (plastic or the like). The optimal configuration is to form a recess in the lingual aspect of the anterior tooth and load the recess with an artificial tooth. In the molar, the artificial tooth is inserted in a band-like shape surrounding the largest protruding portion of the artificial tooth. Further, for fixing (positioning), a magnet is attached to a fixed portion of the artificial tooth mold.

According to the present invention, a dedicated articulator is not required. Existing articulators can be used. For example, in the case of an articulator having an incisal table and a movable table, an artificial array can be attached to the table attachment portion. In the case of the fixed type, an artificial arrangement can be attached to a part in a form surrounding the table.

Although the standard for mounting a model on an articulator differs depending on the method of producing a denture (occlusal theory) by a dentist, an articulator that meets the standard for mounting a model can be used in the present invention.

The device of the present invention can adjust the angle of the occlusal plane according to the reference, whether it is the Campel plane or the Frankfurt plane, by the shift plate attached to the flexible clamp.

When a working model with an occlusal floor is mounted on an articulator, the median and occlusal planes may be displaced. However, the shift plate attached to the flexible clamp can match the median and occlusal planes on the occlusal floor.

The jaw ridge of the patient is not only a state of absorption of the jawbone which is good for the arrangement of the artificial teeth. Surprisingly many cases are clogged and in which artificial teeth are difficult to enter (the degree of absorption is low or the alveolar crest is high). In this case, since the device of the present invention can temporarily put the artificial tooth in a state of being inserted into the artificial tooth mold (try-in), the removal adjustment of the base surface can be easily performed.

According to the present invention, it is possible to arrange the teeth in accordance with the general occlusion theory and the arrangement theory according to the shape and size of each patient's teeth, even if the person is not an expert.

Moreover, with such an artificial tooth arrangement,
Work time can be greatly reduced.
