Abstract
The utility model discloses an improved dental arch splint, comprising a main dental arch splint body fixed on teeth and hooks for dragging a rubber ring, wherein a plurality of tooth rings for fixing the main dental arch splint body on a dentition are arranged on the main dental arch body; the tooth rings are matched with the teeth in size; the area is gradually reduced from two ends of the main dental arch splint body to the center position of the main dental arch body; each hook is arranged at the tail end of each tooth ring and is of an integral structure with the connected tooth rings. According to the improved dental arch splint disclosed by the utility model, the main dental arch splint body is fixed on primary molar teeth; the main dental arch body is further fixed on the dentition through the tooth rings, so that the improved dental arch splint can be applicable to deciduous dentition and mixed dentition of children. The dental arch splint is fastened by screwing the tooth rings, so that the fastness of the dental arch splint is improved. One hook is integrally arranged on each tooth ring, so that elastic traction between jaws is facilitated.
Description
Technical field
This utility model belongs to medical auxiliary system, relates to a kind for the treatment of apparatus, relates in particular to a kind of improvement Arch bar splint.
Background technology
Fracture of mandible is clinical common phenomenon, and between Arch bar splint ligation jawbone, drawing fixed form is conventional expectant treatment method, utilizes the fixedly correction function of Arch bar splint, can effectively treat fracture of mandible.Yet for child's primary dentition and mixed dentition, conventional Arch bar splint exists size easily to come off compared with being difficult to be fixed on less deciduous teeth or after fixing greatly, and to tooth and the larger problem of gingiva wound.
So, be necessary to provide a kind of improvement Arch bar splint, applicable to child's primary dentition and mixed dentition, and can improve the tightness of Arch bar splint, and can reduce the wound to tooth and gingiva, to overcome above-mentioned technological deficiency.
Utility model content
Technical problem to be solved in the utility model is: a kind of improvement Arch bar splint is provided, applicable to child's primary dentition and mixed dentition, and can improve the tightness of Arch bar splint, and can reduce the wound to tooth and gingiva, to overcome Arch bar splint of the prior art, exist size easily to come off compared with being difficult to be fixed on less deciduous teeth or after fixing greatly, and to tooth and the larger defect of gingiva wound.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of improvement Arch bar splint is provided, comprise: be fixed on the Arch bar splint main body of tooth and for drawing the hook of elastic tape, in described Arch bar splint main body, be provided with several for Arch bar splint main body being fixed on to the tooth circle in denture, the size of described tooth circle and tooth matches, and from the two ends of Arch bar splint main body, the center to Arch bar splint main body reduces area successively, described hook is positioned at the end of each tooth circle, and is integral type structure be connected tooth circle.
Improvement Arch bar splint of the present utility model has the meaning of the osteotomy of instructing in operation on mandible, has facilitated operation technique, and has improved accuracy and the safety of operation.
In above-mentioned improvement Arch bar splint, described Arch bar splint main body arises from respectively left and right sides tooth, becomes bifilar twisted shape out of shape in denture lip buccal side, merges, and be fixed in denture by tooth circle in central incisor lip side.
In above-mentioned improvement Arch bar splint, described hook is the end continuity of tooth circle, and becomes 30-35 degree angle with described Arch bar splint main body.
In above-mentioned improvement Arch bar splint, the Arch bar splint main body that described Arch bar splint is split and tooth circle are split-type structural.
Adopted technique scheme, the beneficial effects of the utility model are: compared with prior art, a kind of improvement Arch bar splint of the present utility model, Arch bar splint main body is fixed on deciduous molar, by tooth circle further fixedly Arch bar splint main body in denture, make this improvement Arch bar splint applicable to child's primary dentition and mixed dentition, by tightening the fastening Arch bar splint of tooth circle, improve the tightness of Arch bar splint, and be wholely set a hook on each tooth circle, facilitated intermaxillary elastic traction.A kind of improvement Arch bar splint of the present utility model, applicable to child's primary dentition and mixed dentition, and can improve the tightness of Arch bar splint, and can reduce the wound to tooth and gingiva.
Accompanying drawing explanation
Fig. 1 is the structural representation of the improvement Arch bar splint of this utility model embodiment;
Wherein, 1 is Arch bar splint main body, and 2 is hook, and 3 is tooth circle, and 4 is tooth.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating this utility model, but can not be used for limiting scope of the present utility model.
Fig. 1 is the structural representation of the improvement Arch bar splint of this utility model embodiment.
As shown in Figure 1, a kind of improvement Arch bar splint of the present utility model, comprising: Arch bar splint main body 1 and hook 2, Arch bar splint main body 1 is for fixing teeth 4, with treatment fracture of mandible, hook 2 is for drawing elastic tape, and auxiliary Arch bar splint main body 1 is treated fracture of mandible.
Particularly, first Arch bar splint main body 1 fixes by both sides second deciduous molar ligation, and form the main body of Arch bar splint, meet at forward afterwards central incisor, the tooth circle 3 that size by several and the tooth 4 that arrange on it matches is further fixed on Arch bar splint main body 1 in denture, specifically, from the two ends of Arch bar splint main body 1, the center to Arch bar splint main body 1 reduces the area of this tooth circle 3 successively, makes this improvement Arch bar splint applicable to child's primary dentition and mixed dentition.Hook 2 is positioned at the end of each tooth circle 3, and be integrated be connected tooth circle 3, this tooth circle 3 all becomes bifilar twisted shape with this hook 2, by tightening tooth circle 3, increase the tightness that Arch bar splint main body 1 is connected with tooth 4, when facilitating ligation maintenance tooth 4, also improved the tightness of this improvement Arch bar splint.
In this utility model preferred embodiment, hook 2 and 1 one-tenth 30-35 degree angle of Arch bar splint main body, preferably, be set to 30 degree.
In another preferred embodiment of this utility model, preferably, Arch bar splint is that split production generates.Particularly, adopt the steel wire of 0.6mm to manufacture molding, first steel wire is made to bifilar twisted shape after ligation bilateral second deciduous molar respectively, at central incisor, converge ligation, at tooth neck formation arc, on each tooth, steel ligature is done further fixing and making hook more afterwards, to carry out elastic tape intermaxillary traction.
As mentioned above, a kind of improvement Arch bar splint of the present utility model, Arch bar splint main body is fixed on deciduous molar, by tooth circle further fixedly Arch bar splint main body in denture, make this improvement Arch bar splint applicable to child's primary dentition and mixed dentition, by tightening the fastening Arch bar splint of tooth circle, improved the tightness of Arch bar splint, and on each tooth circle, be wholely set a hook, facilitated intermaxillary elastic traction.A kind of improvement Arch bar splint of the present utility model, applicable to child's primary dentition and mixed dentition, and can improve the tightness of Arch bar splint, and can reduce the wound to tooth and gingiva.Improvement Arch bar splint of the present utility model has auxiliary bone block reset and fixing meaning in fracture of mandible operation, has facilitated operation technique, and has improved accuracy and the safety of operation.
This utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
