Orthodontic positioning device

The present invention relates to a positioning device for an orthodontic device, and more particularly to a positioning device for a dental orthodontic appliance.

Before orthodontic treatment, the orthodontic appliance must be adhered to each tooth surface to be corrected, and in order for the teeth to be aligned, the orthodontic appliance must be correctly adhered to the contour of each tooth, and Parallel to the long axis of the root. Therefore, the commonly used means in the past is to first create a customized dental mold for the patient, and to position the dental appliance on the dental mold, and then transfer the dental tray of the elastic material into the mouth of the patient. However, the disadvantage of this method is that the means are complicated and the implementation cost is high, so it is gradually replaced by the auxiliary positioning device.

However, in the past, the positioning device used in the orthodontic device lacked a perfect scale ratio, and there is no clear size range in the positioning length interval. Therefore, the installation position must be adjusted by the physician according to experience, and the convenience is slightly insufficient.

Because of this, the author is based on the spirit of actively inventing and creating a "positioning device for orthodontic appliances" that can solve the above problems. After several research experiments, the present invention has been completed.

The main purpose of this creation is to provide a positioning device for the orthodontic device. The unique tooth scale design can help the doctor to perform the positioning and installation of the orthodontic device, and limit the distance between the adjacent two tooth portions to 0.5 PCT, which is the optimal displacement distance, can properly take into account the appearance of teeth of different sizes, and achieve convenience in use.

In order to achieve the above object, the positioning device of the tooth orthosis of the present invention helps a dental appliance to be positioned on a corresponding tooth, including a base and a positioning portion. The pedestal is engaged in a receiving groove of the orthodontic device as a reference point for positioning, and can be taken out after use; the positioning portion is fixed on the base and has a plurality of teeth, the plurality of teeth including There is at least one transverse tooth portion and at least one longitudinal tooth portion, and the tooth portion is used as a positioning scale for the doctor to adjust and position.

Wherein, the distance between the at least one lateral tooth portion and the at least one longitudinal tooth portion is 0.5 mm. Therefore, after optimization design, the creation sets the distance between the lateral tooth portion and the longitudinal tooth portion to 0.5 mm, which is most suitable as the amount of change when the orthodontic device is moved. In actual operation, the orthodontic device is positioned. The fine adjustment of the device is not easy to shift excessively, and it has simple scale calculation, which is an accurate and practical positioning device.

The at least one lateral tooth portion and the at least one longitudinal tooth portion may each have a pointed positioning point. Thereby, when the positioning device is used to adjust the position of the orthodontic device, the pointed positioning point contributes to the discrimination of the scale, and accurately positions the dental appliance in the correct position, thereby effectively reducing the occurrence of errors and allowing the final tooth to be produced. The type is more perfect.

The positioning portion may further include an additional tooth portion for positioning a base position of the dental appliance; in addition, the distance between the additional tooth portion and the base may be 2 mm. In this way, in addition to the positioning and positioning of the positioning part, the creation can additionally perform secondary positioning by the auxiliary function of the additional toothing, so that the physician has more reference points as a basis to improve the precision during installation.

The positioning device of the above-mentioned orthodontic device can be used for full-mouth correction, and the tooth position includes a right upper 1~5, a left upper 1~5, a lower right 1~5 and a lower left 1~5, and a total of 20 teeth. In this way, the creation positioning device can use a wider tooth position, and provides a full-tooth dental orthodontic positioning function, so that the physician can be used without being restricted by the tooth position.

When the tooth position of the tooth orthosis corresponding to the tooth is upper right 1, upper right 3, upper left 1, upper left 3, lower right 3 and lower left 3, the distance between the end of the positioning portion and the base may be 6 mm; when the orthodontic device When the tooth position of the corresponding tooth is the upper right 2, the upper right 4, the upper right 5, the upper left 2, the upper left 4, the upper left 5, the lower right 4, the lower right 5, the lower left 4 and the lower left 5, the distance between the end of the positioning portion and the base may be It is 5.5 mm; when the tooth position of the tooth orthosis corresponds to the right lower side 1, the lower right side 2, the lower left side 1 and the lower left side 2, the distance between the end of the positioning portion and the base is 5 mm. Therefore, for the teeth of different teeth, the length used by the creation positioning part will be different to meet the needs of the tooth type.

The upper surface of the positioning portion may be marked with a corresponding tooth number. Therefore, since each positioning device differs only in the length of the positioning portion, the marking of the tooth position can help the doctor to quickly identify the positioning device of different lengths to avoid misuse.

The above summary and the following detailed description are exemplary in order to further illustrate the scope of the patent application of the present invention. Other purposes and advantages of this creation will be explained in the following description and illustration.
