Detailed Description
As shown in figure 1, the embodiment provides an adjacent space trimming clamp which clamps a tooth socket and generates an appliance traction hook notch on the tooth socket by a specific structure in the using process and comprises a correcting clamp body;
the correcting pliers body comprises a handle unit, a functional unit and a middle torsional joint 300;
the handle unit is connected with the functional unit through a middle torsion joint 300, and the effect of controlling the opening and closing of the functional 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 is composed of a raised head working part 220 and a recessed head working part 210;
when the first handle 110 and the second handle 120 are gradually closed, the protruding head working part 220 and the recessed head working part 210 are also gradually closed 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 nose working portion 220 has a raised structure 222 thereon;
the height of the convex structure 222 is not less than 1mm, and the convex structure is provided with a circular arc-shaped boss with 2-3 working angles; in this embodiment, the reason why the height of the protrusion 222 is not less than 1mm is that the thickness of the appliance is generally 0.5-1mm, and it is difficult to trim the protrusion 222 below 1 mm. The lug boss is provided with 2-3 working angles, so that the lug boss can be suitable for a plurality of regions, the lug boss comprises two types of angles, the acute angle or right angle working angle range is 20-90 degrees and is suitable for the region with smaller gap expansion degree, and the obtuse angle working angle range is 91-160 degrees and is suitable for the region with larger gap expansion degree. The setting of convex boss can make and rescue one when ware clearance edge is pruned and cut the shaping, and the round edge makes and rescues the difficult fracture of ware. And when the raised head is set to be three working angles, the acute angle or the right angle working angle must be parallel to the pliers body, so that the three working angles can be guaranteed to be effective working angles.
The width range of the protruding head working part and the edge step of the protruding structure is 0.5-1.5 mm.
The step width range of the working part of the raised head and the edge of the raised structure is 0.5-1.5mm so as to avoid the phenomenon that the edge of the raised structure can be clamped with the appliance when the step is too wide and the edge of the raised structure is sheared.
The functional unit and the middle torsion joint connecting part are in the shape of an inwards concave arc on the side surface, and the upper surface 222-1 of the convex structure 222 has a certain radian, so that the phenomenon that the deformation of the appliance is influenced due to the fact that the forceps head touches the edge of the appliance when working can be effectively prevented.
The thickness range of the through hole of the concave head working part is 0.5mm-2 mm.
The thickness range of the through hole of the concave head working part is 0.5mm-2mm, because the through hole part of the concave head working part needs to extend into the deep area of the inner side of the appliance, if the thickness of the through hole is less than 0.5mm, the through hole is easy to break; if the thickness of the through hole is more than 2mm, the through hole can not extend into the deep area of the inner side of the incisor of the appliance, and the adjacent gap edge of the incisor of the appliance can not be trimmed, so the optimal range of the thickness of the through hole of the concave head working part is 0.5mm-2 mm.
The inner surface 211 of the female working portion 210 is positioned as an arcuate surface, the arc of the arcuate surface 211 matching the arcuate surface 222-1 of the male structure.
Above-mentioned concave head work portion 210's internal surface 211 adopts the radian design, is because the setting that adopts the radian can make to rescue the ware clearance edge and prune and obtain the moist edge, and sharp edge leads to the fracture of correcting the ware very easily when correcting the ware and taking, and the moist edge makes to correct the difficult fracture of ware, and the patient contacts with gum department and also can not oppress the gum when wearing and correcting the ware, leads to painful.
As shown in fig. 4, in the process of straightening teeth, the teeth are straightened by putting the invisible appliance dentition system on the teeth. However, in the orthodontic process, the condition that the patient wears and corrects and presses the gum to cause pain is avoided from causing inaccurate cutting. Need the doctor to handle the ware edge of correcting, cut off the stealthy unnecessary adjacent clearance of correcting on the ware to can avoid patient's pain, cut the position in adjacent clearance on the facing.
As shown in fig. 5, in the using process, the convex working end of the head of the forceps body is placed in the adjacent gap area of the invisible appliance, the concave working end 210 is placed on the inner side of the appliance, and the working angle suitable for the adjacent gap area is selected for shearing.
In addition, the raised structure 222 is provided on the raised working portion 220, and the working angle shape of the raised structure 222 can be set according to the requirement, and the working angle can be set according to different angles, positions and directions to be suitable for cutting the region with smaller or larger gap opening. Such as by using the configuration shown in fig. 6. The number of working angles on the raised structure 222 can be 3, and two obtuse working angles are set for the doctor to conveniently use the adjacent gap trimming clamp to cut the region with larger gap expansion degree.
