Abstract

The utility model provides a tooth grinding band tongue side connector which is composed of a tooth grinding band, a base, key ways, key bodies, a thin metal wire and a connecting rod, wherein the base is fixed on the tongue side surface of the tooth grinding band, and is provided with two key ways vertical to the axis of the tooth grinding band; one end of the connecting rod is provided with the two key bodies and the thin metal wire for fixing; the key bodies are inserted into the key ways so as to form a connecting mechanism. The base is fixed on the tongue side surface of the tooth grinding band; the key bodies on the connecting rod can be vertically positioned in the key ways on the base, and a bow expanding device, an anchorage reinforcing device and a tooth grinding band are connected simply and efficiently, and also can be taken down simply for adjustment and stress application, and are installed again; the necessary welding or binding for the connection of the tooth grinding band is prevented, so that the processing time is saved, also the band is not required to be detached for adjustment each time, the pain of patients is relieved to a large extent, and the waiting time is saved.

Description

Molar band tongue side connector

Technical field

This utility model discloses a kind of molar band tongue side connector, belongs to appliance technical field in the mouth cavity orthodontic orthodontic.

Background technology

Often correct the anti-jaw of backteeth with expanding the bow device clinically, and increase molar anchorage with hyoid arch, Nance bow and horizontal palate bar etc., mobile grinding one's teeth in sleep in even far away, these Therapeutic Method all need elastic part (as four eyed spring, hyoid arch, Nance bow) is coupled together with maintenance part (band).Present connected mode is the welding of elastic part and molar band, perhaps uses tongue side sheath to connect in band tongue side.

The use soldering connects, and not only the operating time is long clinically, complex steps, and must unload band when adjusting at every turn, increased Chairtime, the probability that patient's misery and gingiva damage.Once had the scholar the sixties propose bilateral molar band tongue side weld horizontal to the ovum pipe, by elastic part being inserted the ovum pipe, and realize being connected of elastic part and band with the band ligation.But due to the ovum pipe be level to, so when augmentor inserts the ovum pipe path of insertion be also level to, this operates inconvenient in narrow and small oral cavity, especially lower jaw, use also complex operation of ligature ligation in addition.

Summary of the invention

This utility model provides a kind of molar band tongue side connector, has solved the complicated operation that existing increase molar anchorage technology exists, afterburning hard problem, simplify the manufacturing process of molar band reinforcing, shorten the clinical manipulation time, easy to use, dismounting is simple, applying flexible.

The disclosed molar band tongue of this utility model side connector is characterized in that: be made of molar band, substrate, key way, key, fine wire, connecting rod; Wherein, substrate is fixed on the tongue side surface of molar band, and substrate is provided with two key waies vertical with the molar band axis; One end of connecting rod is provided with two keys and a fine wire that plays the maintenance effect; Key inserts in key way and consists of bindiny mechanism.

This utility model in use, with connecting rod and after expanding the elastic stressing devices such as bow device, four eyed spring, hyoid arch, Nance bow and horizontal palate bar and being connected, two keys on connecting rod are inserted key way, the whole connecting rod of maintenance by the below that fine wire is snapped in key way, thereby elastic part (as expanding bow device, four eyed spring, hyoid arch, Nance bow, horizontal palate bar etc.) is coupled together with molar band, realize rescuing purpose.Can be by opening or crooked fine wire is completed during each dismounting.

The beneficial effects of the utility model are: the tongue side surface at molar band is fixed a substrate, key on connecting rod can vertically be located in suprabasil key way, can will expand simply efficiently the bow device, strengthen anchorage device and be connected with molar band, and can simply above device be taken off, adjust and reinforcing, again bring into.Avoid molar band to connect necessary welding or ligation, thereby saved the time of processing, and need not unload band when adjusting at every turn, alleviated to a great extent patient's misery, saved Chairtime.

On the basis of technique scheme, this utility model can also be done following improvement.

Further, the spacing of described two key waies can according to the band adjusted size, change.

The position of described fine wire can change, can be in two keys are near or between two keys.

The specific embodiment

According to shown in Figure 1, molar band tongue side connector of the present utility model comprises: molar band 6, substrate 2, key way 1, key 3, fine wire 4, connecting rod 5 consist of; Wherein, substrate 2 is fixed on the tongue side surface of molar band 6, and substrate 2 is provided with two key way 1(s vertical with molar band 6 axis with reference to Fig. 2); One end of connecting rod 5 is provided with two keys 3 and a fine wire 4(who plays the maintenance effect with reference to Fig. 3); Key 3 inserts in key way 1 and consists of bindiny mechanism; The whole connecting rod 5 of maintenance by the below that fine wire 4 is snapped in key way 1.

Described two key waies, 1 central point spacing equates with described two keys, 3 central point spacings.Described two key waies 1 are at a distance of about 3.5mm, and internal diameter is 0.9mm approximately.Described key 3 external diameters are slightly less than key way 1 internal diameter.After two keys 3 on described connecting rod 5 insert key way 1, the whole connecting rod 5 of maintenance by the below that fine wire 4 is snapped in key way 1.Can be by opening or crooked fine wire 4 is completed during each dismounting.Described substrate 2 and key way 1 are stainless steel, and the material of described fine wire 4 should have higher anti-fatigue performance and the alloy of intensity.

Claims

1. a molar band tongue side connector, is characterized in that: be made of molar band, substrate, key way, key, fine wire, connecting rod; Wherein, substrate is fixed on the tongue side surface of molar band, and substrate is provided with two key waies vertical with the molar band axis; One end of connecting rod is provided with two keys and a fine wire that plays the maintenance effect; Key inserts in key way and consists of bindiny mechanism.
