Description

Regulating appliance

This utility model relates to a kind of regulating appliance or positive dens supporter.

Known being mainly used in carried out corrigent regulating appliance to deformity teeth and aligned one or more body spares that tooth arch steel wire plays the bearing effect by its position, deep and constitute, these body spares constitute the maintenance base jointly, thereby make the different regulating appliances can be adaptive with same arch steel wire, this arch steel wire stretches along the alveolar arch of receiving treatment.For an independent regulating appliance is conformed to each tooth, the difference that the manufacturing of this class regulating appliance should be looked every teeth patterning and different.The regulating appliance that for example is used for right canine tooth is just different with the regulating appliance that is used for left canine tooth.At present, for the regulating appliance of its tooth relevant with this is discerned, usually with corresponding sign to each regulating appliance labelling in addition, as shown in Figure 1, this sign is by being positioned at constituting away from numeral on the gums limit or color dot of regulating appliance, and the coding shown in the figure is made of one " 2 " on the connecting wing (A) of the body spare that is combined into maintenance base (B) and a stain.But this identification code on the regulating appliance limit certainly will be not too obvious, also not too is easy to identification, even can see the surface, also has only 1 square millimeter usually, and is quite limited, thereby is easy to cause visual fatigue and makes mistakes for the part orthodontist.

The U.S.'s 5326259 patents have disclosed a kind of method of manufacturing the regulating appliance that has sign, and this sign is arranged on the epimere of the body spare that is combined into the maintenance base.Though this method is very complicated, this method in common still has above-mentioned shortcoming.United States Patent (USP) 5622494 relates to a kind of dental aligners of plastics, and this appliance has the structure of protrusion, and the structure of this protrusion is by outwards stretching in conjunction with base, and this forms a land in conjunction with base in conjunction with the free margins of base and projective structure.This part in conjunction with base is the open area that does not have projection, so that can suppress identification marking thereon.

But this known appliance can not be realized the identification marking of suppressing and be easy to the degree by orthodontist's identification.Fact proved that the increase of mark zone must make that the land is corresponding to be dwindled and relevant combined function descends.In addition, the molded selection probability of appliance integrated structure that certainly will cause to identification marking is limited, described molding technique for example just can not adopt under the situation with the very reliable of netted integrated structure and the positive dens supporter through fully checking, this is because molding technique means whole distortion, certainly will cause in conjunction with network structure impaired from function.

United States Patent (USP) 5595484 has been described a kind of positive dens supporter of beauty treatment of plastics.The maintenance base has identification marking, this identification marking be molded in the maintenance base slightly on recessed part, so positive dens supporter and relevant tooth in conjunction with the time, identification marking is not too obvious.Molded identity marking will make part orthodontist's vision overtired in little recessed in positive dens supporter tongue shape surface, and its reason is that described labelling is too little.And when this situation, molding technique will cause on the network structure occurring the distortion of not allowing, thereby can not be with the positive dens supporter that has with cancellated maintenance base.

The purpose of this utility model provides a kind of regulating appliance, and this regulating appliance has identification coding more easy to identify when using.

According to this utility model, this purpose is to realize by following feature.Regulating appliance of the present utility model, have the maintenance base (B) that is used for corresponding tooth and have the relevant identification marking of its tooth that cooperates with it, it is characterized in that: regulating appliance, have the maintenance base (B) that is used for corresponding tooth and have the relevant identification marking of its tooth that cooperates with it, it is characterized in that: described maintenance base B has a network structure, and described identification marking is arranged on the dorsal part of described maintenance base B.

Described identification marking is made of double-digit numeral.

Described identification marking by one or preceding be equipped with or after be equipped with or the numeral of the one digit number of "+" number or "-" number constitutes.

Described identification marking adopts laser equipment to manufacture.

Advantage of the present utility model is, need not to change the structure of regulating appliance and improves its fixing when using, promptly can prepare with simple, reliable and the cheap mode of expense and be easy to the identification code discerned.

In addition, be zero owing to the thickness of identification marking of the present utility model is actual, thereby opposite with the situation of positive dens supporter with molded identification marking, can not cause adverse influence to the anchorage of maintenance base on tooth.

Another advantage is that sign is not carried out with the preparation or the assembling of positive dens supporter.Described labelling realized by corresponding red ink paste used for seals, this labelling even also be applicable to the positive dens supporter of plastics of beauty treatment.

Any those skilled in the art is read following explanation by the contrast accompanying drawing all will understand further characteristic of the present utility model better, and shown in the drawings only is an embodiment of the present utility model, and this utility model is not played the qualification effect, shown in the figure:

Fig. 1 adopts the cut-away view of the regulating appliance of habitual identification code;

The dorsal view of Fig. 2 regulating appliance of the present utility model.

As shown in drawings, the primary structure of the positive dens supporter of this utility model, the body spare (C) that is combined into this maintenance base by a maintenance base (B) and two constitute and have a bearing that is used for positive tooth arch steel wire appropriate section.Regulating appliance has and is arranged on maintenance base (B) dorsal part, promptly with the adherent side of tooth on the sign that constitutes of digital code (" 22 " among Fig. 2).In the example of Fig. 2, conform to the recognition system of " FDI " (international dental medicine community) system, the coding of regulating appliance is corresponding with the position of the tooth that it cooperates with it, wherein as shown in the table, can adopt that two increase progressively is digital labels to tooth, usually from center line, right side on preceding ten numerical code expressions wherein, second ten numerical code expression upper left side, a thirty numerical code expression bottom left side and the 4th ten numerical code expression bottom right sides:

18 17 16 15 14 13 12 11	21 22 23 24 25 26 27 28
18 17 16 15 14 13 12 11	21 22 23 24 25 26 27 28	48 47 46 45 44 43 42 41	31 32 33 34 35 36 37 38

For example represent central incisor down when adopting this mode with 41 and 31, or the like.

Any other tag system of tooth position equally also can be realized this purpose valuably.For native system is done further explanation and for the method be familiar with technical staff in the work of this field consistent, above-mentioned identification code by sign tooth preposition or after be equipped with "+" or "-" number the one digit number sign indicating number constitute, this "+", "-" number expression number is the right side, still, 3+ represents right canine tooth ,-4 expressions first lower-left premolars.No matter use which kind of mode, select which kind of labelling for use, the mark zone that a broad is all arranged on back of the body base section (B), this district even 9 mm square are arranged, thereby digital big I distinguishes therewith and conforms to, thereby makes the orthodontist be easy to identification, indefatigability, avoid makeing mistakes and treating with secured fashion.
