Technical Field

The invention relates to a personalized molar distal appliance.

Background

In the early correction of the dentognathic deformity, for the case that the dentition is slightly and moderately crowded, the correction without tooth extraction can be tried, and the molar is pushed to be far away to be in a neutral relation by using the oral and external corrector, so that the gap aligned teeth are obtained. Common corrective measures include: an extraoral labial arch and palate movable or fixed appliance, a pendulum appliance, a digital-Jet appliance, a magnetic appliance, a implanted nail pushing molar and the like.

Among the above-mentioned appliance of correcting, the movable ware of correcting such as extraoral labial arch relies on patient's cooperation greatly, if not wear enough time then the curative effect is poor, bulky, pleasing to the eye. The plastic base of the palatal movement or fixation appliance is large in size and insufficient in comfort. The swing appliance, the digital-Jet appliance, the magnetic appliance and other intraoral appliances are often thrust on the palate side or the lip side alone, force is applied to the dental crown in a single direction, and the cheek or the palate of a molar is inclined towards the far middle without passing through an impedance center, so that the distancing effect is not achieved, or the orthodontia is lost to cause the mesial inclination of the premolar, the lip inclination of the premolar loses the anchorage, the plane angle of the mandible rotates clockwise and the like. The implant nail pushes the molar teeth, and the implant may damage the tooth root or loosen due to periodontal inflammation for invasive operation.

The above problems are issues that should be considered and solved in the design and production of appliances for pulling molar distal.

Disclosure of Invention

The invention aims to provide an individual molar distal orthodontic appliance to solve the problems of large volume, insufficient comfort and difficulty in achieving a distal movement effect or an unsatisfactory distal movement effect in the prior art.

The technical solution of the invention is as follows:

the utility model provides a ware is rescued to individualized molar far away which characterized in that draws: including the anchorage subassembly with be used for the application of force in treating the molar draw molar subassembly, the anchorage subassembly is connected and is drawn the molar subassembly, the anchorage subassembly includes connecting piece and a plurality of retainer, the retainer is located respectively on anchorage tooth and/or the lower anti tooth of resorption, draw the molar subassembly including the location song, draw the hook, tongue side tongue is detained, buccal side tongue is detained and the elastic tension piece, tongue side tongue is detained, buccal side tongue is detained and is bonded respectively at the tongue side and the buccal side of treating correcting the molar, the crooked tip of location passes through location portion and connects the anchorage subassembly, another tip of location song is equipped with draws the hook, location song and treating to grind the interformation removal region, the hook is drawn in the one end connection of elastic tension piece, tongue side tongue is detained or buccal side tongue is detained to the other end connection of elastic tension piece.

Furthermore, the traction hooks are arranged in one-to-one correspondence with the lingual-side and buccal-side lingual buckles, and the traction hooks are respectively connected with the lingual-side and buccal-side lingual buckles through the elastic tension pieces.

Furthermore, the positioning curve comprises a horizontal part and a bent part, the end part of the horizontal part is connected with one end part of the bent part, the other end part of the bent part is connected with the positioning part, a moving gap is formed between the horizontal part and the molar to be corrected, and the traction hook is arranged on the horizontal part.

Further, the positioning curve adopts an L-shaped curve, and the bending part and the horizontal part jointly form an L shape.

Further, the towing hook is provided on the distal side of the horizontal portion of the L-shaped curve.

Further, the positioning curve and the positioning part jointly form a C shape.

Furthermore, the elastic tension piece adopts a tension spring or a chain-shaped rubber ring.

Furthermore, the connecting piece adopts a tongue side plate, the tongue side plate is respectively connected with the tongue side of the retainer, and the tongue side plate is bonded with the tongue side of the upper jaw teeth or the lower jaw teeth through an adhesive.

Furthermore, the retainer adopts a metal half-crown, and the metal half-crown is adhered to the dental crown occlusal surface of the upper support resisting tooth or the lower support resisting tooth through an adhesive.

Further, the upper anti-teeth adopt first premolars, second premolars and/or first molars on both sides of the upper jaw, and the lower anti-teeth adopt first premolars, second premolars and/or first molars on both sides of the lower jaw.

The invention has the beneficial effects that:

the individualized pulling molar far-middle appliance utilizes the far-middle space of the last upper jaw molar or the space of the lower jaw molar rear cushion, and the positioning curve of the pulling molar component, the pulling hook and the continuous pulling force of the elastic pulling force piece directly act on the molar to be corrected, so that the aim of far-middle and far-middle movement of the molar to be corrected is effectively fulfilled. Through elastic tension member elasticity afterburning, make full use of elastic tension member's active time, the extension spring can be lastingly provided and rescued power, only need treat when beginning to be connected with buccolingual side tongue buckle, need not to change the spring in the treatment, and is easy and simple to handle, and efficiency is higher, can effectively reduce the time that the process was moved far away to the molar. This kind of individualized molar is drawn and is rescued ware to far in, rescues the accuracy, rescues efficiently, can treat by drawing the molar subassembly and rescues the molar and apply the pulling force, moves to far in, effectively realizes the purpose of rescuring.

The individualized molar far-center pulling appliance has the advantages that the connecting piece and the retainer are arranged respectively, the anchorage tooth is connected into a whole, the occurrence that the upper anchorage tooth and the lower jaw tooth move in the near-center or the tongue rotates in the tongue direction can be limited, the anchorage can be enhanced, the effect of correction is guaranteed, adverse effects on other teeth are avoided, the whole size of the appliance is small, and discomfort is avoided.

The individualized molar tooth pulling far-middle appliance is fixed on an upper anchorage tooth or a lower anchorage tooth through the anchorage component, and a patient does not need to take the appliance by himself or herself, so that the appliance does not depend on the cooperation of younger patients, and the maximum exertion of the appliance function is guaranteed.

Fourth, this kind of individualized molar is drawn to ware of correcting to far-in, at each design extension spring structure of bucco-lingual side, can treat by drawing the molar subassembly and correct and applys pulling force by the sick tooth, wholly remove to far-in. Compared with the traditional treatment of pushing molars, the appliance is changed into pulling molars, and the accuracy of treatment can be ensured by pre-calculating the moving distance of the molars to the far center. Simultaneously, the bonding position of the upper tongue buckle of the molar tooth to be corrected is more flexible, can be adjusted at any time according to the treatment condition, and can be closer to the gum side with the bonding of the upper tongue buckle, so that the force action of the tooth is closer to the center of impedance, the whole body moves far, and the treatment efficiency is improved.
