Description

The bracket positioning and fixing tweezer of mouth cavity orthodontic balance appliance

Affiliated field:

In the mouth cavity orthodontic fixed orthodontic system balance correcting process bracket bonding fixedly the time clamping bracket at the bonding apparatus that uses with the location of crown portion.

Background technology:

At present clinical employed bracket location tweezers are that square bracket is used; And the function of having only the clamping bracket; Bracket placement need be confirmed the particular location of bracket with supporting groove locator after corona, the process of operation too bothers and can not in the bonding process of balance appliance bracket, use, and the balance bracket of clamping is prone to and comes off or in fixation forceps, swing; The resin of basilar part is bonding often inhomogeneous in bonding process, and influences bonding effect.

Summary of the invention:

Morphological characteristic according to balance appliance bracket; Operating in the requirement that need reach in the bonding process according to mouth cavity orthodontic is prerequisite; With lip side bracket and linguoplate groove can be shared requirement; Process with operation simply efficiently is a target, according to the form of above original intention design balance appliance bracket positioning and fixing tweezer.Bracket positioning and fixing tweezer is made up of corresponding circle of sensation, elastic region, holding area and back bending district; Wherein the holding area comprises smooth areas, pattern zone and stretching area, and the back bending district comprises bent back portion and tweezer oral area, and the length overall of bracket positioning and fixing tweezer is 160 millimeters; The free-end of corresponding circle of sensation is sharp rounded form; Nearly free-end is wideer than elastic region intersection, and corresponding circle of sensation is the thickest zone in the bracket positioning and fixing tweezer, also is the zone of individualism; The length overall that merges is 20 millimeters, and the wideest position width is 10 millimeters, and the width that corresponding circle of sensation and elastic region have a common boundary is 8 millimeters, and the thickness of corresponding circle of sensation is 3 millimeters, and the edge of corresponding circle of sensation is the right angle.The length overall of each elastic region is 20 millimeters; The nearly corresponding circle of sensation of elastic region is narrower than the dipped beam skating area of elastic region, and the width of the mistaken nearly corresponding circle of sensation of elasticity is 8 millimeters, and the width of dipped beam skating area is 10 millimeters; Thickness is 1 millimeter, and the thickness of two elastic regions is the thinnest zone of bracket positioning and fixing tweezer integral body.The total length of each smooth areas is 25 millimeters; Thickness is 2 millimeters; The position width that smooth areas and elastic region have a common boundary is 10 millimeters; The interface bit width of smooth areas and pattern zone is 11 millimeters, and two lateral smooth areas in holding area and elastic region intersection are the arc elevation surface, and the width of smooth areas and pattern zone intersection is greater than the width of smooth areas and elastic region intersection.The decorative pattern form of each pattern zone is the anti-skidding design of projection; Flash line and flash line intersect the formation decorative pattern, and the intermediary width of pattern zone is the wideest position of bracket positioning and fixing tweezer, and the pattern zone length overall is 45 millimeters; The interface bit width of pattern zone and smooth areas is 11 millimeters; The width at the position, boundary of pattern zone and stretching area is 8 millimeters, and the width of pattern zone center line portion is 13 millimeters, and the thickness of pattern zone is 2 millimeters.The side of each stretching area is slick, and stretching area and pattern zone intersection width are greater than the width of stretching area and back bending district intersection.The width at the position, boundary of stretching area and pattern zone is 8 millimeters, and the width at stretching area and position, boundary, back bending district is 5 millimeters, and the length overall of stretching area is 20 millimeters, and stretching area thickness is 2 millimeters, and the edge of two holding areas is the smooth design of arc.The form in two back bending districts is that " C " shape is crooked, and the position width that back bending district and stretching area have a common boundary is 5 millimeters, and the intersection width of back bending district and tweezer oral area position is 2 millimeters, and the back bending district is thick to be 2 millimeters; The back bending district comprises that the length overall of tweezer oral area is 20 millimeters, and the width of the width of the height of tweezer oral area and pattern zone and corresponding circle of sensation is on same parallel lines, and the width that back bending district and tweezer oral area have a common boundary is lower than the width of back bending district and stretching area, and the tweezer oral area has a common boundary to the tweezer body of the boundary of back bending district and stretching area and is designed to arc; Two tweezer oral areas have a common boundary to the medial surface of the elastic region and the position tweezer body of corresponding circle of sensation boundary all be slick plane, two tweezer oral areas touch mutually, two tweezer body inside are the fusiformis gap, the side form of two tweezer oral areas; Be bread-like, the width of tweezer oral area greater than with the width of back bending interface, tweezer mouth place is an arc; Two free-ends of arc tweezer mouth are parallel with tweezer body inner plane, and triangle lamellar trip card is arranged at arcual back, lay respectively at the central protrusion portion of two radians; The arc of tweezer oral area and the arc of bent back portion are consistent, but vary in size, and the arcual span of tweezer oral area is 3.5 millimeters; The length of tweezer oral area is 2.5 millimeters, and the tweezer mouth is long 2.5 millimeters, and tweezer mouth and back bending place junction are 1 millimeter fan-shaped transition; Long 3.5 millimeters of trip card, wide 2.5 millimeters, thick 0.5 millimeter; Having a common boundary with trip card with arc is starting point, and every millimeter is on the trip card and scale marker is arranged, totally 3; When two tweezer mouths closed up, the maximum in tweezer mouth fusiformis gap was 2 millimeters, and the arcual thickness of tweezer oral area is 0.5 millimeter.Bracket positioning and fixing tweezer is all processed with medical stainless steel or medical high-elastic alloy.Can be that hybrid metal is processed, also can be that special plastic resin or metal-resin mixing manufacturing forms.
