Description

Bracket positioning forceps

Technical Field

The utility model relates to a support slot location tweezers.

Background

In the fixed orthodontic correction, the accurate positioning of the bracket is important. When an orthodontist bonds a bracket, 3 instruments including tweezers, probes and a mouth mirror are needed. The operation method generally comprises the steps that an orthodontist clamps a bracket through tweezers, places the bracket with a bottom plate adhered with resin on a tooth surface, removes adhesive overflowing around the bracket through a probe, puts the probe into a bracket groove to adjust the position of the bracket according to clinical experience, respectively checks whether the position of the bracket is positioned in the center of a clinical crown of the tooth surface from a (occlusal) surface or a cutting end and a labial and buccal surface through a mouth mirror, and then adjusts through the probe according to the observed position of the bracket. The probe used in clinic is a cone-like structure with a sharp tip and a diameter increased from small, and when the bracket is adjusted, the diameter of the rear part of the probe is larger than the diameter of the groove and cannot enter the groove of the bracket completely, so that certain obstruction is brought to the adjustment of the position of the bracket. When adjusting bracket position, just abnormal doctor need use mouth mirror tractive mouth angle to and utilize mouth mirror observation bracket position, so can use 2 mouth mirrors or both hands alternative use mouth mirror usually, in addition the replacement of tweezers, probe, 3 kinds of apparatus of mouth mirror is used, and the bonding process will become loaded down with trivial details and inefficiency. When bonding the support groove (especially preceding tooth district), support groove position adjustment need combine adjacent tooth support groove level, and just the visual accurate location of can not be observed to orthodontic doctor, if support groove position bonding position is incorrect, needs the reposition support groove in the future.

CN207220894U discloses an integrated bracket forceps in 2018, 4 and 13, which comprises a forceps head, a forceps body and a forceps tail; the forceps head is positioned at one end of the forceps body and is connected with the forceps body through a forceps neck; the forceps head is a bracket forceps head, and the forceps tail is arranged at the other end of the forceps body; the forceps tail comprises an oral lens, a lens support and a periodontal probe head; the mirror support is of an arc-shaped structure, one end of the mirror support is fixedly arranged at the other end of the forceps body, an oral mirror clamping groove is formed in the inner diameter of the mirror support, and the oral mirror is fixedly arranged on the mirror support through the oral mirror clamping groove; the other end of the lens support is provided with a periodontal probe head. The utility model can not only be used for holding the bracket and placing the bracket on the tooth, but also can adjust the position of the bracket through the periodontal probe; meanwhile, the bracket can be positioned through the scales arranged on the needle point of the periodontal probe at the forceps tail and the mouth mirror at the forceps tail. The defects of the method are as follows: taking the maxillary middle incisor as an example, the width of the maxillary middle incisor is generally 8.5cm to 9.5cm, and the bracket forceps have a small mouth mirror and insufficient visual field range, so that the observation is inconvenient; moreover, when the position of the bracket is adjusted, the distance between the position of the bracket and the position of the bracket of an adjacent tooth is about 5-6 mm, the odontoscope part of the bracket forceps can be blocked by the bracket of the adjacent tooth, the bracket forceps can not be completely inserted into the groove for adjustment, the use is inconvenient, and the accurate positioning can be influenced; the distance between the central point of the bracket of the cuspid and the cuspid of the cuspid is 5mm, the longest scale of the periodontal probe of the bracket forceps is 4.5mm, the measurement length is larger than the scale shown by the periodontal probe, and the positioning accuracy of the bracket is influenced when the bracket of the cuspid is bonded.
