Abstract

The utility model relates to a moveable straightening machine distally and moveably grinding teeth, and mainly corrects the first permanent molar which shifts toward the mesio position after loss of second primary molar. The moveable straightening machine is characterized by consisting of a retention unit, a strengthening unit and a connector, wherein the strengthening unit is divided into a distal end and a mesio end. The distal end is a vertical curved unit, and the mesio end comprises a pair of horizontal tension curve and a tail wire. The tail wire is connected with the retention unit through the connector integrally. The moveable straightening machine has the advantage that the direction of the acting force of the straightening machine is vertical to the stressed face of shifted molar in the process of reset of distal movement of molar without generating component force for intrusion of molar. In the process that the molar strengthened moves toward the distal end, the contact area is expanded from line to surface to the benefit of stably applying the acting force, so that the strengthening steel wire is not easy to slide toward the oeclusal face or gum.

Description

Mobile removable appliance of grinding one's teeth in sleep in far away

Technical field

The utility model relates to a kind of mobile removable appliance of grinding one's teeth in sleep in unusual far away of oral cavity molar locations of correcting, the main rectification because second deciduous molar early loses the direction displacement near of back sixth-year molar.

Background technology

Because after a variety of causes causes second deciduous molar early to lose, being arranged in its sixth-year molar far away can be mobile to nearly (being the place ahead), but 2 ~ 4 roots owing to ground one's teeth in sleep, move in its place ahead is not moving horizontally of single integral body and be that tooth moves to mesial inclination mostly, reset so under most of situation it is set upright to reach in sixth-year molar far away, but the afterburning part of far middle mobile removable appliance of grinding one's teeth in sleep all is that grinding one's teeth in sleep of inclination applied the strength of horizontal direction at present, active force is that stress surface becomes certain included angle but non-perpendicular to stress surface with the near middle proximal surface of grinding one's teeth in sleep, after this active force decomposes so, except the tooth of turning a millstone middle mobile component far away, also have to press and grind one's teeth in sleep to the component of root side, grind one's teeth in sleep thereby force down, not only influence occluding relation, and can cause the root resorption of grinding one's teeth in sleep.

Summary of the invention

The utility model proposes a kind of middle mobile removable appliance of grinding one's teeth in sleep far away, its purpose is intended to reduce and eliminate the active force of grinding one's teeth in sleep that forces down that produces when existing appliance moves in the tooth of turning a millstone is far away.

Technical solution of the present utility model: its structure is by the maintenance unit, afterburning unit and connector three parts are formed, wherein afterburning unit is divided into distal end and nearly middle-end, distal end is one and vertically opens the Daqu (massive raw stater for alcholic liquor) unit, nearly middle-end comprises a pair of Horizontal Tension song and tailfiber, and tailfiber is linked to be an integral body by connector and maintenance unit.

Advantage of the present utility model: appliance is in the process that the tooth of turning a millstone resets in far away, the stress surface that force direction is ground one's teeth in sleep perpendicular to displacement always, can not produce and force down the component of grinding one's teeth in sleep, and grind one's teeth in sleep far away again after setting upright in the process of movement, the contact area expands the face contact to by line, more help the stable of active force to apply, make rescue steel wire be difficult for to Tooth closesSlide in face or gum side.

Description of drawings

Fig. 1 is the scheme of installation of appliance.

Fig. 2 is the application of force process sketch map of afterburning unit.

1 is the maxillary first molars, the 2nd of mesiogression among the figure, vertically opens Daqu (massive raw stater for alcholic liquor), the 3rd, Horizontal Tension song, the 4th, tailfiber, the 5th, one-arm clasp and embrasure hook, the 6th, lip bow, the 7th, one-arm clasp, the 8th, afterburning unit, the 9th, connector (plastic base), the 10th, the vertical afterburning transverse arm of opening Daqu (massive raw stater for alcholic liquor).

The specific embodiment

The contrast accompanying drawing, the structure of appliance is by the maintenance unit, afterburning unit 8 and connector 9 three parts are formed, wherein afterburning unit 8 is divided into distal end and nearly middle-end, distal end is for vertically opening Daqu (massive raw stater for alcholic liquor) 2, nearly middle-end comprises a pair of Horizontal Tension bent 3 and tailfiber 4, and tailfiber is linked to be an integral body by connector 9 and maintenance unit.

Described maintenance unit comprises one-arm clasp and embrasure hook 5, lip bow 6, one-arm clasp 7, and they link to each other successively by connector.

Described afterburning unit distal end is that vertical an open Daqu (massive raw stater for alcholic liquor) 2 parallel with the proximal surface of grinding one's teeth in sleep adds unit of force, vertically opening Daqu (massive raw stater for alcholic liquor) 2 contacts with the maxillary first molars 1 of the mesiogression that need rescue, the movement locus of vertically opening Daqu (massive raw stater for alcholic liquor) 2 application of force processes is to be camber line, maxillary first molars 1 proximal surface that the afterburning transverse arm 10 of vertically opening Daqu (massive raw stater for alcholic liquor) is opened back and the mesiogression generation active force that offsets; Vertically open a pair of Horizontal Tension song 3 of near middle connection of Daqu (massive raw stater for alcholic liquor).Vertically open the unlatching of the similar books of Daqu (massive raw stater for alcholic liquor) application of force process, movement locus is not the straight line of level, but is camber line, adds force direction and remains with the stress surface of grinding one's teeth in sleep in the upright process of grinding one's teeth in sleep and be vertical.The nearly middle-end of afterburning unit 8 comprises Horizontal Tension bent 3 and tailfiber 4, when grinding one's teeth in sleep uprightly, opens big flood sheet Massa Medicata Fermentata, can impose the active force of horizontal direction to grinding one's teeth in sleep; Tailfiber 4 is linked to be an integral body by connector 9 and maintenance unit and with on the zone that the counteracting force transmission is dispersed to appliance contacts.

Afterburner process is: at first wire-shaped is faded among the figure behind the dotted portion and appliance to be worn the upper jaw into the patient, steel wire deformation part will be back to position before the deformation along dotted arrow indication extruding, because the elasticity capacity of steel wire produces the power be back to position after the deformation, this elastic force acts on grinding one's teeth in sleep of being in contact with it, thereby will grind one's teeth in sleep and slowly set upright Xiang Yuanzhong and move, counteracting force is distributed on the anchorage tooth and mucosa jawbone that contacts with appliance by connector and fixing device.
