Description

The protrusion of protrusion, particularly pacify and so on

The present invention relates to a kind of pacify class thing, particularly relate to the pacify class thing of pacify of sucking requirement that is not satisfied of being intended to satisfy child and so on.

In the last few years, in order to eliminate child to the sucking of finger, pacify class thing was by more and more widely use.Nearly 90% child has formed and has sucked custom, and 60% among them adopt pacify class thing/pacify.Studies show that the custom that present child sucks pacify class thing/pacify keeps than more permanent in the past, and use more frequently than in the past.

Using known and conventional roars of laughter baby is the rear portion patho-occlusion (crossbite) that tightly forms because of firmly stinging with a serious consequence of the pacify class thing of pacify and so on.This is because the convex shape pneumatophore of pacify is in the bottom in oral cavity to the lower compression tongue.Therefore, the alveolar arch body of maxillary lose the supporting and because of buccal pressure to intrinsic pressure.Simultaneously, tongue with the alveolar arch body of lower jaw to external pressure.Recent studies show that: use pacify class thing the Sweden girl 26% (see also Am J OrthodDentofac Orthoped, 1994 because of firmly stinging the tight patho-occlusion that has formed the rear portion; Among the 106:161-6 by  gaad B, " suck custom, strand (cohort); sex, interior canine tooth (intercanine) arc width and suckling and nursing bottle form the influence of patho-occlusion backward to Norway and 3 years old child of Sweden " that LarssonE, people such as Lindsten R. deliver).

Patho-occlusion with forced guidance is a kind of serious interlock mistake, and this interlock mistake may cause the growth promoter of jaw portion to produce bigger deviation.Therefore, national health department provides to greatest extent compensation for this treatment, but child's tooth treatment usually is complicated and child is under the unnecessary tense situation.

Another serious consequence of using pacify class thing be so-called " open type interlock " (openbite), this open type interlock is by having thick between the known pacify class thing requirement tooth and being straight passage and the consequence that produces.

In the pacify class thing of pacify and so on, the free air bag of convex shape pneumatophore (child relies on this air bag to suck) is equipped with a dish type stop-motion body, this dish type stop-motion body forms an outer supporter that is suitable for being resisted against on child's lip, be in child's the mouth so that prevent whole pacify class thing, thereby prevent that child from swallowing whole pacify class thing.Should have one handle or analog usually by outer arresting disc.

The pacify class thing of DE3840178 and the disclosed pacify of US5133740 and so on has common feature and working method.Pacify class thing device-be convex shape pneumatophore itself-with each of these pacify class things, their design and shape are so designs, promptly two local air bags that merge present U/V shape cavity in non-merging zone, and this cavity begins to dwindle into taper gradually towards the arresting disc direction from two free overhang of air bag.The tip of the tongue is followed and is entered in the described cavity.This moment, this pair arch pneumatophore was transited into straight tube-like part or the rectangular bulk portion that extends of external mutually arresting disc.

The design of these known pacifies and shape will force the tongue of natural torsion to leave its natural motion track/zone.These known solutions all require to have big space in the oral cavity, herein, say ideally, and tongue should be able to be in the top in oral cavity along whole alveolar arch body.These known pacify class things all have one at interdental thick and straight passage.This also is disadvantageous, is wide between tooth because people wish to obtain one originally, and passage is extended in thin inclination.In addition, these pacify class things will cause tongue to be pressed downward alveolar arch body to lower jaw, therefore can form the shortcoming of " open type interlock ".

According to the described pacify class of DE3840178 thing, its distinguishing characteristics especially is: the pneumatophore of this pacify class thing will force tongue downwards and leave natural place at the toxoplasmatic inboard place of the alveolus of maxillary.This will cause forming foregoing patho-occlusion and force-lead lower jaw.

US5133740 discloses a kind of pacify with many and conventional pacify same characteristic features.If tongue places described cavity, then tongue must become a kind of factitious shape and can not keep its position at the top, oral cavity.After time grown, this will cause forming inappropriate interlock.

Main purpose of the present invention is: provide a kind of and allow during sucking and help the pacify class thing that tongue is in the tram.Therefore, tongue will be along the lying of maxillary alveolar arch body, and keep the oral cavity top-side to its supporting so that balance buccal pressure.To the sucking in the process of this pacify class thing cystidium, tongue is had an opportunity in mouth as much as possible to protracting child.

According to the present invention, its purpose can realize by the pacify class thing that is made of the described feature of claim 1.

Other attendant advantages of the present invention according to claim 1 is limited by following each dependent claims.Therefore, an additional but important purpose of the present invention is: be in correct position in order to guarantee pacify class thing in mouth; Mainly be that asymmetric shape owing to pneumatophore guarantees.

Therefore, the pneumatophore of this pacify class thing that is carried by a middle transition coupling part is asymmetric in side view (use location), and it is shaped as a bending curve, also may be part bi-curved or plate shape, this panel-like member comprises the air bag part of two different lengths, the lower gasbag part that air bag part is relatively long carries out the transition to a quite short upper gasbag part more smoothly, the latter and this long balloons part shape at an angle, as described in side view.

This design and shape, especially combine the new feature of outer arresting disc after, can prevent that tongue is to pressing down and forward against the jaw of staying.

The outer end of this long balloons body, the i.e. air bag part of the foot of this pneumatophore when correct use location, the outer end that cans be compared to this short air bag part to the distance at the center of the transition coupling part of brace place pneumatophore most is the biggest to the distance at the center of the transition coupling part of brace place pneumatophore.

Arresting disc is made up of two half ones in lateral shift.More particularly, longitudinal center's part at this arresting disc, this described relatively center of two longitudinal components/half is asymmetric, and wherein the surface that should go up the arresting disc part facing to this pneumatophore mainly is to recessed song, and forms in the part of this surperficial length range at least.And the respective surfaces of arresting disc mainly is protruding upward down, and forms in the part of this surperficial length range at least.The purpose of this design and shape is especially in order to guarantee that each jaw portion can be in upper-lower position respectively relative to each other.Following labial teeth will be in the inboard of Upper Anterior Teeth.In addition, this position is favourable to location and the bearing position of optimizing tongue.This pacify class thing forms a ramp way of having a mind between tooth, it is to preventing that labial teeth is in errors present and can plays a part certain.This shape of arresting disc, the entire portion or the major part that are its length (highly) direction can have horizontal concave curved surface (the outer mouth portion with child with respect to the use location is relative), also the correct location tool of this pacify class thing in mouth are had certain effect.If the pneumatophore of pacify class thing is in wrong position, promptly put upside down 180 °, then will run into the bridge of the nose for the outer plate portion under corresponding to plate portion outside in the pneumatophore structure itself but in this mistake use location, the topmost portion of this arresting disc is that chin will be run in uncomfortable mode in the bottom of pneumatophore structure itself simultaneously.Then child can feel to detest and make expression at once, if for example spue this pacify class thing or this pacify class thing are still stayed in the mouth and it can be rotated back into the tram.

In the use location, the air bag part that this is short, this part will constitute short extendible portion sucking part of pneumatophore, to be resisted against on the front portion of this plate, and be in the labial teeth back, and combine with the remainder of the given shape of this air bag, make tongue not be forced to leave the top in oral cavity.

The free end of this long balloons part can be quite sharp to prevent that reliably tongue from entering below this air bag.This capsule part of losing heart is limited by a flat relatively surface and forms.

This middle transition coupling part, particularly in the part of approximate centre, it is quite little and width is quite big to make thickness, so that described quite little thickness is carried out the compensation of intensity aspect.Approach but wide part at this, it is the approximate centre part (big centre between pneumatophore and arresting disc) of the length direction of transition coupling part, the reverse opposed grooves that formation has the notch cross section is extremely favourable, and they can be in the longitudinal direction biasing of this transition portion.The opposed grooves down of the last groove when constituting the use location is held the labial teeth on mouth top, and the opposed grooves up of the following groove during the formation use location can be held the labial teeth of mouth bottom.

This design of described middle transition part, particularly little thickness has positive role to greatest extent to allow tongue during sucking to protracting in mouth.

The outside of arresting disc, especially limiting wall is preferably formed by the pearl periphery, when this arresting disc or its part enter in child's lip, can make child feel to detest.

Can be formed with many extensible horizontal communication holes at this arresting disc or its part by the arresting disc wall.

Below in conjunction with one shown in each accompanying drawing may embodiment non-limiting example other advantage and the feature of the pacify class thing that designs according to the present invention and be shaped further specified, wherein:

Fig. 1 represents the side view of the pacify class thing that forms according to the present invention;

Same side view when Fig. 2 represents that identical pacify class thing is in the use location has wherein shown lower lip, the upper jaw and the lower jaw and the tongue of band tooth;

Fig. 3 represents the perspective view of the pacify class thing that illustrates from seeing sideling down.

In this exemplary embodiment, illustrate the shape that pacify class thing of the present invention has pacify, it generally includes following each parts/part: a nonessential handle ring 10, this handle ring 10 is suspended on the supporting slice 12 free to rotately, this supporting slice 12 can divide 14 to fixedly connected or make one with a junction, this coupling part 14 has two asymmetric part 16a that extend continuously each other with one and the arresting disc 16 of 16b is fixedlyed connected, and vertical (vertically) core of this arresting disc 16 is in that relative use location (as shown in Figure 2) is brokenly and the extension of non-rectilinear ground between the two ends up and down.Be provided with a transition coupling part 20 between arresting disc 16 and pneumatophore 18, pneumatophore 18 is arranged at the free end of this transition coupling part 20.

In described longitudinal median plane (hatching among Fig. 2), constitute two longitudinal component 16a of extending part each other mutually, 16b roughly interlaced layout.In the use location, except in the junction of core transition coupling part 20 on arresting disc 16, the following arresting disc part 16b that has towards the curved surfaces of pneumatophore 18 will separate a bigger distance by the imaginary plane that is hung vertically in the handle ring 10 on the supporting slice with one. and arresting disc part 16a that these are offset mutually and 16b have formed and have been suitable for the stop surfaces that child's lip is used, as shown in Figure 2, upper lip 22 is resisted against on the arresting disc part 16a, and lower lip 24 is resisted against on the arresting disc part 16b.

Can clearly learn from Fig. 3: arresting disc 16 has each passage 26 at lateral direction penetrating.Even therefore child holds in the mouth this arresting disc 16 in mouth, he also can breathe.

Can clearly learn from Fig. 1-3: the horizontal of this arresting disc 16 is concave curved surface.

The shape of this middle transition coupling part 20 and size are so to form, width is quite big so that its thickness is little, particularly in this coupling part 20 is in zone in the mouth, be in the zone of (as Fig. 2) between the labial teeth 28 of the labial teeth 26 on lip top and lip bottom, all the more so.

In the zone of just having mentioned, this transition coupling part 20 has both direction groove 30 and 32 opposite and present groove shape in the longitudinal section (specifically referring to Fig. 3) respectively.

Can clearly learn from Fig. 2: this Upper Anterior Teeth 26 is to nip downwards in the top of transition coupling part 20, the groove 30 that is open upwards and points to downwards with how being directed to, and down labial teeth 28 be upwards nip with how being directed to the bottom of transition coupling part 20, downwards in the unlimited groove 32.This low groove 32 than the upper groove 30 of this transition coupling part 20 more near pneumatophore 18.

The pneumatophore 18 that is arranged at the free end of this transition coupling part 20 has an outer surface 18 ' and the recessed distortion in the junction of this pneumatophore 18 of free end of this transition coupling part 20 that deviates from this transition coupling part 20, (its described relatively junction may have one laterally recessed curved) comprising so that described outer surface part 18 ': a bigger following outer surface part 18a ', this time outer surface part 18a ' carries out the transition to a much smaller last outer surface part 18b ', and the outer rim of whole outer surface 18 ' (shown in the side view as illustrated in fig. 1 and 2) is along an irregular curve extension.

The bottom 18a of this pneumatophore 18 free end outside it has roughly homogeneous thickness to pneumatophore 18 in the junction of transition coupling part 20.Therefore, this bottom 18a has the surface of almost parallel.Have been found that these parallel surfaces are to the location advantageous particularly of tongue during sucking in mouth.

This transition coupling part 20, near the outer part of the junction of pneumatophore 18, the i.e. zone of the described passage of this transition coupling part 20 between tooth, preferably oblique, be acclivitous when being preferably in the use location, thereby during sucking, can make tongue in mouth, be in nature and conventional position.This design and shape are to avoiding the patho-occlusion advantageous particularly.

The conventional pacify class thing of pacify and so on usually causes such as in the open type interlock of lateral parts and the interlock mistake the patho-occlusion.The open type interlock can produce the problem of aesthetics and function aspects to child, but these problems usually can self-correcting after child stops using pacify class thing.On the other hand, the patho-occlusion most probable influences the permanent growth layout of tooth.As previously mentioned, patho-occlusion is to force the bottom that tongue is pressed to the oral cavity downwards to form because of known pacify class thing.Therefore tongue 34 forces outside lower jaw alveolar arch body 36 presses to.Simultaneously, maxillary alveolar arch body 38 is thrown off the supporting of tongues 34, and facial muscle pressure with this maxillary alveolar arch body 38 to intrinsic pressure.Thereby increased disproportionate between the alveolar arch body width of the upper jaw and the lower jaw, this usually causes producing patho-occlusion.The subsidiary phenomenon that leads of being forced to that lower jaw is arranged of the patho-occlusion that uses conventional pacify class thing and cause.This phenomenon is a kind of serious working bite relation mistake, and this mistake pair of jaw parts is in early days carried out orthopaedic treatment, so that eliminate the harmful effect of the growth promoter of pair of jaw parts.

According to the present invention, for fear of the patho-occlusion that is forced to lead and produces because of child's lower jaw, therefore mainly be in order to prevent that this pacify class thing from forcing tongue to be in bottom, oral cavity (this especially may cause the alveolar arch body of maxillary to become too narrow and alveolar arch body lower jaw becomes too wide) downwards, drawn the universal design and the shape of this pacify class thing.When the tooth clinching tooth, lower jaw is forced to stretch out towards a side.On the contrary, according to the present invention, the shape and the design of its pacify class thing are so, so that can prevent the patho-occlusion that is forced to lead and produces because of lower jaw; This point does not have restricted natural place and state by making this pneumatophore and having specific shape and be in relatively in mouth, the tongue 34 of (referring to Fig. 2) is located especially and be directed and realize.Be in the salivary gland below the tongue, frenulum or the like 34 ' still is not on its position by the influence of the pneumatophore 18 of this pacify class thing basically without restriction.If this pacify class owner prevents tongue 34,34 ' is pressed towards down the bottom that is in the oral cavity.

Behind life-time service pacify class of the present invention thing, the particular design of acclivitous passage trend and arresting disc 16 will make tooth obtain normotopia between labial teeth 26,28, and this will be engaged in the inboard of Upper Anterior Teeth 26 in free outer end of labial teeth 28 at present.May opposing molar 42,44 can obtain correct mutual location and orientation each other in addition.

Mainly be the surperficial 18a ' with the pneumatophore 18 of the last side contacts of tongue 34 (referring to Fig. 2), 18b ' as shown in Figure 3, its outer peripheral shape be one in the shape that laterally may have substantially elliptical more crooked and that extend along its longitudinal component at least.This pneumatophore 18, particularly its outer surface 18a ', the specific design of 18b ' and shape are according to section's topic of testing and experience is constantly revised and mated with continuing.Yet, pneumatophore 18 relative its 20 relevant junction point places have asymmetric plate shaped shape in its adjacent axial end and transition coupling part.As described, such plate at an angle also can exist more recessed curved at least one direction, also can have hyperbolical, promptly all exist a bit recessed curved at vertical and horizontal, at least be in the longitudinal extent to a certain degree of this pneumatophore 18, have recessed curved, as so-called elongated (ellipse) pneumatophore 18.But this can not influence the area supported 18a ' of the pneumatophore 18 that makes tongue 34 usefulness at all, and 18b ' adopts square/circular outer periphery shape roughly.

The outer surface 18b ' of this pneumatophore 18 also can be omitted.
