Detailed Description
As shown in fig. 1, the present embodiment provides an arc button cutting pliers, which clamps a tooth socket during use, and generates a gap of a traction hook of an appliance on the tooth socket by a specific structure, and comprises a main body of the cutting pliers;
the correcting pliers body comprises a handle unit, a functional unit and a middle torsional joint 300;
the handle unit is connected with the function unit through the middle torsion joint 300, and the effect of controlling the opening and closing of the function unit through the handle unit is realized, and the opening and closing principle is similar to that of the traditional tool pliers.
In the present embodiment, the handle unit is composed of a first handle portion 110 and a second handle portion 120;
the functional unit consists of a boss working part 220 and a head end working part 210;
when the first handle 110 and the second handle 120 are gradually close to each other, the boss working part 220 and the head end working part 210 are also gradually close to each other to bite the target position;
when the first handle 110 and the second handle 120 are gradually separated, the boss working part 220 and the head end working part 210 are also gradually separated, and the target position is released;
the boss working portion 220 has a protrusion structure 222 thereon;
the raised structure 222 is an oval structure of 4mm by 8 mm; in the embodiment, the working end boss is set to have a width of 4mm because the width of the tongue-side buckle used clinically cannot exceed about 3.5mm generally, the width of the bracket cannot exceed 3.2mm generally, the diameter of 4mm can meet the clinical use requirement, the width of the appliance is reduced when a notch is manufactured, and the mechanical property of the appliance is maintained; and because the shape is oval, can cut higher length when length is 8mm can help the preparation breach, the tongue side is detained and can be installed in tooth buccal surface, the lingual surface, or the tooth face, and length 8mm can satisfy the length that needs cut off, can not influence the mechanical properties of correcting the ware moreover.
In addition, experiments show that when the protruding structure is a circular boss, on one hand, the problem that the extending of the traction structure is difficult due to the small coverage area of the protruding structure is solved; on the other hand, if the traction mechanism is completely and smoothly extended, the diameter of the head of the traction mechanism should be about 6.2mm, but the width of the bicuspid teeth of the human body teeth is about 6-8mm, and if the existing forceps are used for making notches on the invisible appliance, the appliances on the buccal side surface or the lingual side surface of the bicuspid teeth are almost cut off; and also can lead to the breach too big when grinding the tooth position preparation breach, and correct the ware breach and then can lead to correcting the ware more unstable the more, correct the uneven problem of ware power also expression, so, through the experiment discovery, the oval-shaped boss of 4mm 8mm is the optimum from atress and installation effect.
The upper surface 222-1 of the raised structure 222 has a curvature.
The inner surface 211 of the head end working portion 210 is positioned as an arc surface, and the arc of the arc surface 211 matches the arc surface 222-1 of the convex structure.
The radian is designed by adopting traditional clinical medicine generally, the radian which is consistent with the radian of the buccal side surface of the tooth is defined, the radian can be consistent with that of double cuspids, and can also be consistent with that of molar positions 4, 5, 6, 7 and 8, and the radians can be different according to the requirements of different use positions.
The discovery in the research and development process of this embodiment, if the face of cutting the head work end all is the plane with protruding cephalic portion face, because the labial tooth axis of general tooth all has certain radian, so when cuting semicircular breach, the power that plane molding cut the head work end and produce can directly lead to stealthy the problem of correcting the ware and having the deformation, and then make stealthy the ware of correcting to have and not laminate with the tooth face after cuting, thereby stealthy the ware of correcting is difficult to reach predetermined strength and promotes the tooth and remove, and because the distortion problem of uneven surface and edge part under external force, very easily lead to the circumstances of this type of facing after supporting to cause the harm to the gum to take place.
And the pliers head work end and the boss of this embodiment, through setting up the radian, place in the ware inboard is being rescued as the boss part in the in-process that uses, the work end place in the ware outside of rescuring, coincide and rescure ware tooth radian and use the pliers to make and rescure the ware breach, avoided the deformation scheduling problem of the stealthy correction pincers in aforementioned plane, just rescues the ware and can not appear not laminating the condition of tooth face when wearing, can not influence the mechanical properties who rescues the ware.
As shown in fig. 2, the head end working portion 210 has an oval through hole 212 corresponding to the position of the protrusion; the shape and size of the through hole are matched with those of the convex structures.
As shown in fig. 3, in the process of straightening teeth, the teeth are straightened by putting the invisible appliance dentition system on the teeth. However, in the process of straightening teeth, in order to avoid causing the movement and inclination of unnecessary teeth, auxiliary force applying devices such as lingual buckles or traction hooks must be added properly to the worn tooth socket. As shown in fig. 4, the invisible orthodontic pliers provided by the embodiment are formed by cutting semicircular notches at the gingival-direction edge of the transparent appliance (tooth socket) according to the requirement of the traction hook, so as to provide space for sticking lingual buttons or brackets on the tooth surface, and the wearing of the transparent appliance is not affected.
In the using process, the lug boss-shaped working end of the head of the forceps body is placed on the inner side of the invisible appliance and extrudes the tooth socket with the working end of the head of the forceps, so that a traction hook notch of the appliance is generated.
In addition, the notch shape of the traction hook of the appliance can be set according to requirements, and the working end of the lug boss can generate notches with different shapes according to different sizes, positions and directions. Such as by using the configuration shown in fig. 6. The bottom of the working end of the boss is added with a radian shape, so that a smooth notch edge is obtained when a doctor uses invisible correcting pliers-arc button shearing pliers to manufacture a notch conveniently.
In addition, the width of this boss work portion is for following the structure that the head direction diminishes gradually, traditional pliers class product, therefore, the head that flat-headed or rectangular shape is than broad head, the circular boss head of its crop work end generally has the boss edge about 1.5mm, and the boss edge is that the rectangular shape is than broad big, when using, need stretch into the inboard of correcting the ware with shearing head boss work end, the excessive boss edge of boss head leads to shearing the pincers can not cut out required breach toward occlusal surface direction on correcting the ware.
