Description

Tooth surface bracket pliers

Technical Field

The utility model relates to the field of medical supplies, specifically speaking relates to a tooth face holds in palm groove pincers.

Background

In the fixed orthodontic technology, the removal of the bonded bracket is a key step in the whole treatment process; the removal force of orthodontic brackets is determined by the following factors: bracket type and retention mechanism, removal method, adhesive composition and enamel treatment method. Due to the improvement of the acid etching technology and the production process of the adhesive, the bonding between the bracket and the enamel surface is firmer, the improvement of the bonding strength enables the bracket separation to be transferred from the enamel-adhesive interface to the bottom plate-adhesive interface, and the separation of the bracket is realized by applying stress to the bracket by the bracket pliers, so that the bottom plate is deformed to be separated from the adhesive and fall off.

In addition to using mechanical methods, the bracket removing technology such as laser, electric heating, ultrasonic removing method and the like is also used; the most convenient method for clinical use is still mechanical removal. Present clinically existing remove support groove pincers can satisfy the needs that the clinical bracket was removed, but it is unfavorable for clinical operation, there is the inconvenient problem of application of force, the support groove pincers of straight shank design only can exert stress when pliers and tooth face are perpendicular, and just abnormal doctor still need exert force when guaranteeing to hold steady pliers and tooth face vertically, make the application of force not convenient enough, high efficiency, and because the restriction of patient's opening degree and oral angle soft tissue, often need the supplementary tractive mouth angle of using the mouth mirror hard, expose the crown and leave enough spaces in order to guarantee that the pincers handle is perpendicular with the tooth face, patient's discomfort has been increased, just abnormal doctor's the operation degree of difficulty has also been increased.

Detailed Description

In order to further understand the structure, characteristics and other objects of the present invention, the following detailed description is given with reference to the accompanying preferred embodiments, which are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention.

The utility model provides a tooth face holds in palm groove pincers, combine figure 1, figure 2, including left tong bar 1, right tong bar 2 and handle 3, left tong bar 1 is articulated with 2 one end of right tong bar, notch 4 of two T shapes is seted up respectively to

left tong bar

1 and 2 articulated department one sides of right tong bar, notch 4 opposite direction on left tong bar 1 and the

right tong bar

2, 3 one end of handle is also the T pole, the T pole of handle 3 is pegged graft in notch 4, so that 3 length direction of handle is different with

left tong bar

1, 2 length direction of right tong bar, can make 3 length direction of handle and left tong bar 1 be perpendicular with 2 length direction of right tong bar, can make the part that stretches into patient's oral cavity reduce, alleviate the contact pressure of support groove pincers with patient's gum and lip, reduce patient's uncomfortable sense.

With reference to fig. 1 and 2, the notch 4 penetrates through the left clamping bar 1 and the right clamping bar 2, the notches 4 near the two sides of the left clamping bar 1 and the right clamping bar 2 in the length direction respectively penetrate through the right clamping bar 2 and the left clamping bar 1, so that the handle 3 can be respectively embedded into the left clamping bar 1 and the right clamping bar 2 when the positions are changed, the thickness of the handle 3 is smaller than the thickness of the left clamping bar 1 and the right clamping bar 2, and the handle 3 embedded into the left clamping bar 1 and the right clamping bar 2 can be stably fixed.
