Abstract
The utility model discloses a corrector for pushing and grinding teeth backwards, which comprises a small jaw support device, a correcting device for pushing and grinding teeth backwards, and a band ring. The front end of a spring supporting sliding rod of the correcting device for pushing and grinding teeth backwards is provided with a tractive circle of a ligature thread. The ligature thread is penetrated through the tractive circle. The far end of a sliding orbit of the correcting device for pushing and grinding teeth backwards is provided with a flat plug. The shape of a hole of a cheek pipe on the band ring is matched with the flat plug. The utility model has the advantages of simple operation, stable fixation of positions, and obvious and smooth therapeutic effect of pushing and grinding teeth backwards.
Description
This utility model relates to a kind of dental care equipment, is applicable to the mouth cavity orthodontic specialty, is mainly used in to rescue the crowded case of the property II class misfit of tooth source and labial teeth, and its function is for opening up the gap backward, squeezes denture and the adjustment intermaxillary relation of grinding one's teeth in sleep.
External existing a kind of Lokar distance removing device of grinding one's teeth in sleep.This appliance is made up of anchorage and active force two parts, and anchorage partly is little palate holder (Nance holder), promptly 55 or VV on the system wear ring, make continuous fibers with 1.0 millimeters stainless steel silks of diameter, be welded in band palate side.Use the plastic cement embedding then, band cheek face down bonding has traction apparatus, active force partly is exactly the Lokar distance removing device of grinding one's teeth in sleep, by sliding bar, stainless steel round wire, the NiTi helical spring is formed, during its sliding bar is far away a side plug is arranged, directly insert in the buccal tube of finished product side's silk bow band, circle silk leading portion has a pipe as the retardance point, and front end leaves 2mm circle silk end and fastens certain portions as traction ligation silk altogether.Because the tiny insertion buccal surface of its plug side's silk square tube, stability is relatively poor, compares with large-area distance removing device, especially as " nose heave, foot light, shallow the end of with ", easily fractures.In addition, front end stiff spring fixedly ligation silk is partly short and thin, under masticatory pressure, slippage easily, affects the treatment.Sealing-off partly takes place in little palate holder, loses anchorage immediately, does not cushion leeway.
This utility model purpose is to be to provide a kind of novel tooth appliance backward of turning a millstone, and overcomes the grind one's teeth in sleep deficiency of distance removing device of Lokar, and it is easy and simple to handle to reach the doctor, and the appliance maintenance is stable, can continue to discharge the power of rescuing.The tooth of turning a millstone is steady backward, and curative effect is obvious, and the tooth of turning a millstone is similar to whole moving backward, reduces patient's further consultation rate and appliance repair rate.
For realizing the purpose of this utility model, the inventor proposes following technical scheme: the tooth appliance backward of turning a millstone comprises little palatal plate device, shove-molar backward correction device, band.Spring that the tooth of turning a millstone is rescued backward supports the sliding bar front end ligation silk traction circle is set, and the ligation silk passes the traction circle, turn a millstone tooth backward the sliding rail far-end of appliance be flat plug, buccal tube hole shape and flat plug on the band match.
Because this utility model tooth plug of appliance backward of turning a millstone inserts the special oblate buccal tube of band, is a kind of contact of face of large volume, make whole appliance maintenance stable, be difficult for reversing and fractureing, thereby guaranteed the lasting release of appliance mechanical force; Traction compression spring ligation silk has a specially designed traction circle, prevents that effectively reasons such as buccal motion cause the slippage of ligation silk because of chewing.The little palate holder of association type mainly is provided with movable bridge one-arm clasp commonly used on the bilateral conoides, kept anchor band on the second bicuspid, the associating palate holder of Xing Chenging like this, existing abutment anchorage has the jawbone anchorage of upper jaw palatine again, form a kind of powerful anchorage, if single connecting filament sealing-off takes place, abutment anchorage has certain reserve compensate function, helps stablizing curative effect.

Fig. 2 tooth appliance user mode partial enlarged drawing backward of turning a millstone.
Fig. 3 shove-molar backward correction device configuration diagram.
The oblate buccal tube band of Fig. 4 diagrammatic sketch.
Embodiment:
As shown in Figure 1: little palatal plate device comprises establishes connecting filament 4 in the glue holder 5, connecting filament is connected with band 2, establishes bracket 3 on the band 2; Also be provided with one-arm clasp 1 in the glue holder 5.More than constitute the little palate holder of associating.Turn a millstone tooth backward appliance 6 be connected with oblate buccal tube band 7 with bracket 3.
The tooth appliance 6 backward of turning a millstone as Fig. 3, comprises skateboard track 6.3, establishes pipe 6.5 on the skateboard track 6.3, and spring supports to establish on the sliding bar 6.1 and pushes away spring 6.6.Skateboard track 6.3 far-ends are flat plug 64.Ligation silk 6.7 passes traction circle 6.2.
Oblate buccal tube band 7 as shown in Figure 4.Comprise band 7.2, establish the oblate buccal tube 7.1 that Kong Kaizhuan matches with flat plug 6.4 on the band 7.2.
This traction circle 6.2 is convenient to ligation silk traction maintenance, and flat plug 6.4 guarantees the appliance fixing-stable, does not reverse, and moves after grinding one's teeth in sleep steadily.The anchorage part that to unite little palate holder be appliance offsetting, to absorb the tooth counteracting force of mechanical force backward of turning a millstone, thereby guarantees rectifying effect.Bracket 3 is standing parts that traction pushes away spring ligation silk.
Claims (2)
1, the tooth appliance backward of turning a millstone, it comprises little palatal plate device, shove-molar backward correction device, band, the spring support sliding bar front end that it is characterized in that shove-molar backward correction device is provided with ligation silk traction circle, turn a millstone tooth backward the sliding rail far-end of appliance be flat plug, buccal tube hole shape and flat plug on the band match.
