In order to make the first bite plate cover only partial tooth positions, the tooth positions on the first bite plate comprise a fourteenth tooth position, a fifteenth tooth position, a sixteenth tooth position and a seventeenth tooth position.

In order for the second bite plate to cover only a portion of the dentition, the dentition on the second bite plate includes a twenty-fourth dentition, a twenty-fifth dentition, a twenty-sixth dentition, and a twenty-seventh dentition.

In order to match the first and second bite plates with the tooth positions, the plurality of tooth positions are grooves matched with the teeth.

In order to retain the dental articulator, a plurality of retaining rings are arranged in the first articulator and the second articulator.

In order to facilitate fine adjustment of the distance between the first bite plate and the second bite plate by a doctor through the cross palatal bar, a protrusion convenient for fine adjustment is arranged on the cross palatal bar.

In order to allow for symmetrical fine adjustment of the bite plate, the protrusion is located in the middle of the palatal bar.

In order to reduce unnecessary damage to the patient's mouth caused by the projections, the projections are arcuate.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) the first bite-block board of covering part position of tooth and the setting of second bite-block board can reduce the volume of bite-block board to foreign body when reducing and wearing feels, improves the travelling comfort that the patient wore.

Example 1

Fig. 1 to 3 show a first embodiment of a dental articulator according to the present invention, comprising a first articulator 1 for covering right maxillary posterior teeth and a second articulator 3 for covering left maxillary posterior teeth, wherein the first articulator 1 and the second articulator 3 are connected by a palatal bar 2.

The utility model relates to a dental articulator, which comprises a first articulator 1 and a second articulator 3, which respectively cover partial tooth positions of upper and lower teeth, and reduce the volume of the articulator, thereby reducing the foreign body sensation during wearing; the first bite plate 1 and the second bite plate 3 are connected by the palatal bar 2, which is convenient for the patient to wear and position the bite plates. In this embodiment, the first bite plate 1 and the third bite plate 3 are made of resin material, and the palate bar 2 is made of stainless steel wire.

In addition, the cross palate rod 2 is an arc-shaped structure matched with the palate. The setting of arc structure can improve the travelling comfort that the patient wore.

Wherein, a plurality of tooth positions 4 are arranged on the first bite plate 1 and the second bite plate 3. The arrangement of the plurality of teeth positions 4 enables the temporomandibular joint disorder to be adequately treated.

Wherein, the tooth position 4 on the first bite plate 1 comprises a fourteenth tooth position, a fifteenth tooth position, a sixteenth tooth position and a seventeenth tooth position, so that the first bite plate 1 only covers part of the tooth position, and the volume of the first bite plate 1 is reduced.

Wherein, the tooth position 4 on the second occlusal plate 3 includes the twenty-fourth tooth position, the twenty-fifth tooth position, the twenty-sixth tooth position, the twenty-seventh tooth position, makes the second occlusal plate 3 only cover part tooth position, reduces the volume of second occlusal plate 3.

Wherein, a plurality of tooth positions 4 are all grooves matched with teeth. The arrangement of the grooves enables the first bite plate 1 and the second bite plate 3 to be matched with the position of teeth.

In addition, a plurality of snap rings 5 for fixing are arranged in the first bite plate 1 and the second bite plate 3. The retainer ring 5 is provided to enable retention of the dental articulator. As shown in fig. 1 to fig. 3, two clasps 5 are disposed in the first bite plate 1 in the present embodiment, and are respectively disposed between the fourteenth tooth position and the fifteenth tooth position, and between the sixteenth tooth position and the seventeenth tooth position. Two snap rings 5 are arranged in the second bite plate 3 and are respectively positioned between the twenty-fourth tooth position and the twenty-fifth tooth position and between the twenty-sixth tooth position and the twenty-seventh tooth position. The snap ring 5 and the palate bar 2 may be provided without connection or with connection. When the snap ring 5 is connected with the cross palate rod 2, specifically, two snap rings 5 arranged in the middle first bite plate 1 are both connected with one end of the cross palate rod 2; two snap rings 5 arranged in the second bite plate 3 are connected with the other end of the cross palate rod 2. The free ends of the snap rings 5 arranged in the first bite plate 1 and the second bite plate 3 respectively extend out of the first bite plate 1 and the second bite plate 3.

Wherein, the cross palate rod 2 is provided with a bulge 21 which is convenient for fine adjustment. The protrusions 21 are provided to facilitate fine adjustment of the distance between the first and

second bite plates

1, 3 by the practitioner via the palatal bar 2.

Wherein, the bulge 21 is positioned at the middle position of the cross palate rod 2. The provision of the protrusion 21 in a medial position enables the practitioner to fine tune the bite plate symmetrically.

Wherein the protrusion 21 is arc-shaped. The arc-shaped arrangement can reduce unnecessary damage of the bulge 21 to the oral cavity of a patient.
