Description
Technical Field
The invention relates to a tooth appliance, in particular to a double-pressing-sleeve guide rod compression spring tooth appliance.
Background
A movable appliance device for treating functional and early-stage osseous malocclusion in the stage of tooth formation from left-falling to right-falling in the deciduous tooth period of patients suffering from Angle III malocclusion. After the infant wears the set in the mouth, the pressure generated by the pressure spring is transferred to the upper invisible base and the lower invisible base through the guide shafts of the upper anchorage positioning bolt and the lower anchorage positioning bolt and acts on the upper and lower jaw whole dentition. The formed correcting force acts on the upper jaw and the lower jaw, so that the upper jaw is pushed forwards by the upper jaw invisible base to promote the forward development of the upper jaw, the lower jaw is pushed backwards by the lower jaw invisible base to inhibit the excessive forward development of the lower jaw, the functional retreat of the lower jaw is caused, and the opposite jaw can be effectively corrected.
The stomacher is commonly known as the Shangtian, the academic name of the III-class malocclusion of the Anshi, the anterior teeth are reversely closed, the lower jaw is functionally advanced, and the molar is in the III-class occlusion relationship, namely the lip of the anterior teeth of the lower jaw is inclined, the tongue of the anterior teeth of the upper jaw is inclined, the lower jaw is advanced and displaced, so that the anterior teeth are reversely jawed.
For such patients, functional appliances are mostly used clinically for several decades for orthodontics, namely, pseudo-stroke, left-falling-tooth, left-falling-bone and III-type malocclusion at home and abroad, and appliances disclosed in clinical and patent documents are mainly classified into the following categories:
the method mainly comprises an FR-III type functional appliance and a Twin-Block appliance by means of generating backward force by rigid extrusion, and the patent documents are as follows: the digital muscle function induction appliance and the manufacturing method CN110215298A, a III type individual function appliance CN 105411692B and the like belong to the former variety; the bracket-free invisible appliance for guiding the mandibular movement and the manufacturing method CN110123464A, the mandibular leading invisible appliance CN110063802A, a mandibular advancement guiding and fixing orthodontic combined appliance CN109730788A, an adjustable mandibular advancement appliance CN103565573A, a double pad appliance CN109009497A and the like are all the variants of the latter. Their greatest disadvantage is the high rigidity of the device and the difficulty in adjusting the backward thrust. Especially, the double-baffle plate appliance directly converts the occlusal force into the backward force, and the occlusal force is far greater than the required correction force, so that the side effects of upper labial inclination, lower lingual inclination and the like are easily generated, and even the permanent tooth falls off. In addition, the steel wire and the labial arch of the FR-III type functional appliance can be exposed when being opened, and the double-baffle appliance can not realize complete occlusion when in use, thus seriously affecting the beauty and the comfort.
Magnetic generation of backward force, patent document: the buccal screen type invisible magnetic force functional appliance CN110063803A and the bony class III malocclusion appliance CN 102068316A are all based on the principle. However, the magnitude of the magnetic force has a complex nonlinear relationship with the shape, magnetization intensity and distance of the magnet, and is extremely sensitive to parameter change, and because the consistency of processing and manufacturing of the magnet is poor, the orthopedic device inevitably has processing errors, so that the force application is difficult to control accurately, the force is difficult to keep constant in the treatment stage, side effects are easy to generate, and the surface shape is also easy to be asymmetrical due to the uneven stress on two sides.
The use of elastic elements to generate the backward force, historically the most classical solution, the Herbst Hinge, is also the main object of the present invention. Such as german patent DE19711536a1 and domestic patent literature: the elastic bracket CN107095723A for orthodontic, the labial attachment CN105792771A used with orthodontic aids and lingual appliance system, a spring loaded mandibular advancement appliance CN1803109A, a composite device CN111265318A which advances the mandible while achieving three dimensional movement of orthodontic teeth, etc. are all variants thereof. It is characterized by that the spring is compressed by a rod sliding in the sleeve barrel, so that it can produce the force for pushing lower jaw backward. Because the rod and the sleeve wall are in non-lubrication surface contact sliding friction pairs, the requirements on rigidity, matching precision and surface roughness are high, if the precision is insufficient, or the structure is deformed by non-axial force, the friction resistance can be greatly increased or even blocked, so that a good correction effect can be achieved, the structure must have enough size to ensure the rigidity, and meanwhile, the manufacturing cost is very high for ensuring the precision. This makes the solution difficult to meet the requirements of early correction, especially for Chinese patients with small face sizes, due to size limitations, and the cost of the solution also imposes a great burden on the patients.
In 2006, the buccal multi-curved spring movable appliance CN2006101509758 is used for years of clinical application, and the correction of class iii malocclusion of anshi overcomes some defects of the above scheme, and hundreds of patients have good treatment effect, but some problems are encountered. Firstly, the used multi-bent springs are manually bent, and the mechanical processing and mass production are difficult to realize; and secondly, the long-time stretching, downward stroke and pressing process of the multi-curved spring can cause the problem of fatigue fracture, and the correcting effect is influenced.
Thirdly, the upper jaw support and the lower jaw support are made of self-setting resin, and the jaw growth and the face shape of the children patients can be affected after the children patients wear the resin for a long time; fourthly, the pressure is the largest when the mouth is closed in the process of opening and closing the mouth, the pressure in the process of opening the mouth is gradually reduced to zero pressure, an inflection point appears, the multi-bend spring is converted into tensile stress when the mouth is continuously opened, and the tensile stress is opposite to the orthodontic direction to generate negative effect, so that the orthodontic effect is influenced.
The double-pressing-sleeve guide rod compression spring tooth appliance solves the problems, and has the advantages of simple structure, easy processing, mechanized mass production, low manufacturing cost, easy mastering of technology and clinical popularization and application.
