Problems solved by technology

Although this kind of digital guide template can simplify the use to a certain extent, improve the accuracy, and it will not scrape and squeeze the dentition, and it is convenient to deal with the characteristics of extravasation of glue during bracket bonding, but in actual operation, due to its complex structure , it is necessary to repeatedly insert the straight part of the hook-shaped guide rod into the guide groove, and errors will occur when the straight part of the hook-shaped guide rod is inserted into the guide groove, and it is difficult to ensure the bending part of the hook-shaped guide rod The tightness of the detachable connection with the bracket, and when the device is fixed on the tooth surface, the patient needs to open his mouth for a long time, so that the muscles and nerves are in a tense state, which is not conducive to the patient's cooperation with clinical treatment

Embodiment 1

[0048] The navigation device used to assist the positioning of the labial bracket given in this embodiment has a structure such as figure 1 , 2 As shown, it is specifically composed of a plywood 1, a guide frame 2 and a connecting piece 3. Plywood 1 is in the shape of a horseshoe, matching the shape of the orthodontic patient's gums, and its upper and lower sides have occlusal teeth marks 4 that match the upper and lower dentition of the orthodontic patient; the guide frame 2 is consistent with the number of teeth in the upper and lower dentition of the orthodontic patient , 24 to 32 pieces, whose cross-sectional shape is "L", fixed by the corresponding connector 3 above and below the outside of the plywood, the horizontal opening side of each guide frame is facing the front center line of the plywood, and the right-angled side is The number of connectors 3 is matched with the guide frame 2. It is a long strip, one end is fixed on the outer surface of the splint, and the othe...

Embodiment 2

[0052] The navigation device used to assist the positioning of the labial bracket given in this embodiment has a structure such as image 3 As shown, it is specifically composed of a plywood 1, a guide frame 2 and a connecting piece 3. The difference from Example 1 is: 1) The number of guide frames 2 is 12, which are fixed above the plywood 1 by the connector 3; 2) The thickness of the plywood 1 is 4 mm, and the depth of the occlusal teeth marks is 2 mm; 3) The guide frame 2 The length of the vertical segment and the horizontal segment are both 1 mm, and the thickness is also 1 mm.

[0053] The navigation device provided in this embodiment is suitable for the situation where it is necessary to make a navigation device for the maxillary dentition separately, or the situation where the orthodontic patient only performs orthodontics for the maxillary dentition.

Embodiment 3

[0055] The navigation device used to assist the positioning of the labial bracket given in this embodiment has a structure such as Figure 4 As shown, it is specifically composed of a plywood 1, a guide frame 2 and a connecting piece 3. The difference from Example 1 is: 1) The number of guide frames 2 is 11, which are fixed under the plywood 1 by the connector 3; 2) The thickness of the plywood 1 is 5mm, and the depth of the occlusal teeth marks is 3mm; 3) The guide frame 2 The length of the vertical segment and the horizontal segment are both 2 mm and the thickness is 1 mm.

[0056] The navigation device provided in this embodiment is suitable for the situation where it is necessary to separately manufacture the navigation device for the mandibular dentition, or the case where the orthodontic patient only undergoes orthodontic treatment for the mandibular dentition.

Abstract

The invention discloses a navigation device used for aiding positioning of a labial bracket. The navigation device is composed of an occlusion plate (1), a guiding frame (2) and a connecting piece (3), wherein the occlusion plate (1) is in a horseshoe shape and is matched with the shape of the gum of an orthodontic patient, the upper and lower surfaces of the occlusion plate are provided with occlusion tooth prints (4) matching with upper dentition and lower dentition of the orthodontic patient, the number of the guiding frame (2) is at least one, the cross section of each guiding frame (2) is in an L shape and is fixed above and / or below the outer side of the occlusion plate (1) via the corresponding connecting piece (3), the side, where a horizontal opening is located, of the guiding frame faces the front center line of the occlusion plate (1), and the side, where a right angle is located, of the guiding frame is far away from the front center line of the occlusion plate (1) and is correspondingly distributed relative to an orthodontic tooth. The invention also discloses a manufacturing method for the navigation device. The manufacturing method is simple, mature and easy to promote; and the prepared navigation device is simple in structure, convenient to operate and comfortable, well fits teeth, ensures accuracy of the bonding position of the bracket, omits the step of indirect bonding and improves clinical operation efficiency.

Description

technical field [0001] The invention belongs to the technical field of orthodontic devices and preparation thereof, and in particular relates to a navigation device and a manufacturing method for assisting the positioning of labial brackets. Background technique [0002] In traditional orthodontics, physicians determine the position of bracket bonding by visually observing the clinical center point and the long axis of the clinical crown in the oral cavity. With the development of indirect bonding technology, doctors can now transfer the brackets that have been artificially bonded on the dentition plaster model to the tooth surface in the patient's oral cavity through the transfer device, and can also place the brackets that have been positioned digitally outside the body. After the position is placed on the model, it is transferred to the tooth surface of the patient's mouth. [0003] CN102319124A discloses a "digital guide template for indirect bonding of orthodontic brac...
