Abstract
The utility model develops an adjustable type orthodontic crimpable traction hook. Compared with a traditional crimpable traction hook, the adjustable type orthodontic crimpable traction hook is characterized in that retention can be realized without applying a force to have the hook deformed. the crimpable traction hook comprises two parts, namely a box-shaped body and a bolt; the bolt is screwed into a round hole of the box-shaped body to press an arch wire, and then a force of friction is produced to ensure no slippage between the traction hook and the arch wire, so that the position can be adjusted without dismounting the arch wire, and the height of the traction hook can be selected at will; the size of an opening of the box-shaped body is 0.023 inches *0.028 inches, so that the arch wire can be placed easily; the gum part of the box-shaped body is 1.2 mm in thickness, and the junction part is 0.8 mm in thickness; a hole which adopts an internal spiral structure and is 1 mm in inside diameter is formed in the center of a gum face and is matched with the screw rod of the bolt; the cap of the bolt takes the shape of a hexagon of which the side length is 1 mm, and is 1 mm in thickness; the screw rod is 1 mm in diameter, can be 2 mm, 4 mm, 6 mm or 8 mm in height, and can be used with a hexagon spanner in the same size. During use, the position of the traction hook can be adjusted at will as required, the bolt with a required length can be selected and is screwed into the round hole in the gum direction and tightened with the hexagon spanner, and the arch wire is compressed to be propped against the junction face of the box-shaped body, so that the condition that the traction hook is fixed on the arch wire and does not slip can be ensured.
Description
One, affiliated technical field
This utility model relates to adjustable position for a kind of correction of machine-building and can choose at random the free hook of height, can be used in conjunction with any type orthodontic bow-wire, rescues for malocclusion in the slip of process and receives.
Two, technical background
Free hook is a kind of usual means of straight wire appliance sliding scale moving teeth.Hook drives arch wire and slides, and can make one group of tooth integrated moving.The application of micro-plantation pinlay, more easily realize the integrated moving of one group of tooth, but this requires hook must be fixed on arch wire, does not produce relative shift in distraction procedure.If hook slides near with canine tooth and is close together, can cause between canine tooth and lateral incisor and gap occur, the loosening arch wire that also can affect of hook slides smoothly in distraction procedure.
Now the hook on market has several: the hook directly bent on arch wire, be welded in hook and free hook on arch wire.The first two hook, because make complexity, needs the shortcomings such as dismounting arch wire, and use is very limited.Free hook can be directly installed on arch wire and without arch wire is unloaded in patient's mouth, and position can arbitrarily lay, location easily, have advantages of easy and simple to handle, save time, practical, comfortable, thereby be used widely clinically.Yet 1. the shortcoming of the free hook of traditional open type has hook lay pincers pressure that need to be very large could keep maintenance, and hook easily slides on arch wire during reinforcing, is unfavorable for organizing the integral body slip of tooth; 2. clamp strength is excessive, can cause the arch wire distortion, thereby adjacent teeth is produced to disadvantageous active force; 3. in the situation that do not dismantle the height that arch wire is difficult to random reversing of position and changes hook; 4. dismounting difficulty, change if need or the dismounting hook, has to again to change a new arch wire.
Three, summary of the invention:
In order to keep the advantage of free hook, overcome its deficiency simultaneously, this utility model has been researched and developed free hook for a kind of Novel bolt formula correction, by the bolt compressing arch wire screwed in box body circular hole, produces frictional force.This Novel bolt formula correction hook that dissociates, comprise the subsidiary spanner of box body, bolt and handling bolt.Be characterized as box body intermediate rectangular groove opening towards arch wire, be beneficial in the situation that in mouth without the dismounting arch wire box body is inlaid into to arch wire, box body circular hole is towards gum side, for inserting bolt; Bolt is hexagon cap shape peg, and the circular hole of size and box body is complementary; Spanner is for screwing hex bolts.
The thick 1.2mm of gum section of box body, the thick 0.8mm of the section of closing (as shown in Figure 1) of box body, there is the circular hole that an internal diameter is 1mm internal coiling structure in gum face central authorities.Box body groove is of a size of 0.023 inch * 0.028 inch, and closing gum is 0.023 inch to opening size, is greater than 0.022 inch of the full-size of the arch wire be used in conjunction with the general bracket of correction, is convenient to include the box body in arch wire.The rectangular aperture of box body closes and faces the arch wire direction and high the stopping of 0.5mm is set carries, and prevents that the box body from deviating from arch wire easily.
The hexgonal structure that the cap of bolt is length of side 1mm, thick 1mm, screw diameter 1mm, the dark 0.2mm of screw thread, flight pitch 0.1mm, bolt provides 2mm, 4mm, 6mm, tetra-kinds of height of 8mm.In use procedure, can arbitrarily change as required the position of hook, select to need the bolt of length, screw in circular hole from gum side and screw, arch wire be compressed to the face that closes that props up the box body, can guarantee that hook is fixing on arch wire not slide.Bolt coordinates the die nut of same size to use, and firmly screws bolt, can be afterburning.
The technical solution adopted in the utility model is: adopt the numerical controlled machinery processing method.Box body and bolt are made by the medical stainless steel material, meet its hardness requirement.This design can realize on production line, and machine-shaping is easy, meets the needs of batch production.
Four, accompanying drawing explanation:
Below in conjunction with accompanying drawing, this utility model is described further.
Fig. 1 is front view of the present utility model.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is the top view of Fig. 1.
Fig. 4 is the spanner of hex bolts.
1. hex bolts nuts in figure, the 2. tightening latch of hex bolts, the 3. gum section of box body, the 4. section of closing of box body, 5. square arch wire, 6. stopping of box body carried, 7. box body circular hole.
Five, the specific embodiment:
This utility model application CAD/CAM art designs is manufactured, and raw material adopts the medical stainless steel material to process box body and the bolt that meets data demand through the disposable milling of Digit Control Machine Tool, then reaches the helical structure of screw rod in tapping realizes box body circular hole.Finally, through operations such as polishing, polishing, cleanings, process, reach the surface smoothness requirement.
When this utility model hook is used, in any bracket system, while needing to slide interior receiving portions denture, without the dismounting arch wire, first reserve on arch wire a little, box body rectangular aperture is put into to suitable position towards arch wire, circular hole is towards gum side, the intense adjustment good position, select the bolt of proper height, screw in circular hole, with die nut, screw bolt, the bolt end is propped up to arch wire, make itself and arch wire close contact, now can afterburning traction, if need adjusting position, only need the reverse rotation screw, reorientate and screw screw and get final product.Height as needs adjustment hook, only need to counter-rotate out bolt, and the bolt of changing proper height gets final product.Have and easily realize installing/dismounting, maintenance is good, the advantages such as conveniently adjusted position.
