Description

Orthodontic appliance

Technical Field

The utility model relates to a shell of tooth articles for use field especially relates to an orthodontic appliance.

Background

The bracket-free invisible orthodontic device is a transparent elastic material movable orthodontic device designed and manufactured by computer assistance, is a sequence of continuous orthodontic devices, and achieves the aim of orthodontic by continuous small-range tooth movement. Only some of the teeth may be moved in different stages while the other teeth act as anchorage, thereby completing the straightening of the teeth.

When the existing appliance is used for correcting the tooth form, the inner cavity of the appliance is in surface contact with the tooth surface, the pressure formed by the surface-to-surface contact is always perpendicular to the contact surface, and because the contact surface is an arc surface, a plurality of pressures with different angles and different sizes are formed at each position of the contact surface, wherein one part of the pressures can promote the tooth to move in the expected direction and is called as effective force, and the other part of the pressures can not promote the tooth to move in the expected direction and is called as ineffective force. The pressure provided by the orthosis is limited, resulting in a substantial reduction in effective force due to the ineffectiveness. Ineffectiveness interferes with the effective force, preventing the teeth from moving in the desired direction, further reducing the efficiency of the correction.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the prior art has no effect to interfere with the effective force, prevent the teeth from moving towards the expected direction and further reduce the correction efficiency, and provides the orthodontic appliance.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an orthodontic appliance, includes tooth fixed part, be formed with the alveolus that is used for the tooth to rectify in the tooth fixed part, every two all be provided with the protruding block portion that corresponds with the slit between the tooth, the lateral wall of alveolus is fixed with the ball piece that offsets with the tooth, the ball piece is used for exerting the power of rectifying to the tooth.

Preferably, a flexible sheet is attached to the notch of each dental groove and is used for being in sealing contact with teeth, and the flexible sheets on each dental groove are connected into a whole.

Preferably, the height of the flexible sheet is 1-2mm, and the thickness is 0.3-0.5mm.

Preferably, the tooth fixing element is completely wrapped around the teeth in the oral cavity.

Preferably, the tooth fixing component is wrapped on the tooth to be corrected in the oral cavity.

Preferably, the inner side of the tooth fixing part is provided with anti-skid grains.

Compared with the prior art, the utility model provides a tooth just abnormal unscrambler possesses following beneficial effect:

1. this orthodontic appliance through the ball piece that sets up, can make and exert the effort of accurate direction to tooth, and then improve orthodontic effect.

2. This orthodontic appliance of tooth through the flexible piece that sets up, can play sealed effect when wearing, and the foreign matter drops to its inside when effectively preventing to eat and put.

The part that does not relate to among the device all is the same with prior art or can adopt prior art to realize, the utility model discloses can make and apply the effort of accurate direction to tooth, and then improve the effect of orthodontics, can play sealed effect when wearing, the foreign matter drops to inside when effectively preventing to eat and put.

Drawings

Fig. 1 is a schematic structural view of an orthodontic appliance according to the present invention;

fig. 2 is a schematic top view of the present invention.

In the figure: 1. a tooth fixing member; 2. a dental groove; 3. a boss engaging portion; 4. a ball block; 5. a flexible sheet; 6. and (4) anti-skid lines.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1 to 2, an orthodontic appliance includes a tooth fixing member 1, wherein a dental groove 2 for tooth correction is formed in the tooth fixing member 1, the dental groove 2 can accommodate teeth, a convex engaging portion 3 corresponding to a slit is provided between each two dental grooves 2, a ball 4 abutting against the teeth is fixed to a side wall of the dental groove 2, and the ball 4 is used for applying a correction force to the teeth.

In one embodiment, the tooth fixing component 1 completely covers the teeth in the oral cavity, so that all the teeth can be protected comprehensively, and the wearing stability is ensured.

In other embodiments, the tooth fixing component 1 is wrapped on the teeth to be corrected in the oral cavity, so that the teeth to be corrected and fewer normal teeth are arranged, the material and the cost can be saved, and the aim of correction can be achieved.

Preferably, the inner side of the tooth fixing part 1 is provided with anti-slip threads 6, so that the friction force of the tooth fixing part 1 can be improved, and the tooth fixing part can be conveniently taken down from the teeth in the following process.

The arrangement of the number of the ball blocks 4 is determined according to the orthodontic condition, when the larger teeth are straightened, two ball blocks 4 are required to be uniformly arranged on two sides of the alveolar groove 2, only one ball block is required for the smaller teeth, and the ball blocks 4 are not arranged for the parts which do not need to be straightened.

Wherein according to the needs of correction, ball 4 in the alveolus 2 sets up, simultaneously ball 4 and tooth fixed part 1 integrated into one piece accomplish the production after the design is accomplished, wear tooth fixed part 1 on the tooth again, and then can make its firm second block on the tooth through protruding card and portion 3, guarantee the stability of its use, secondly the effort of applying through ball 4 can act on the tooth more accurately, guarantee the uniformity of atress direction, simultaneously through the bellied setting of ball 4, make the 2 lateral walls in alveolus of other positions contact with the tooth surface, do not carry out the atress.

Wherein in this embodiment, the notch department laminating of tooth groove 2 has flexible piece 5, flexible piece 5 is used for with tooth sealing contact, every flexible piece 5 on the tooth groove 2 connects into a whole, when tooth fixed part 1 was worn on the tooth, can make flexible piece 5 and tooth joint department, realizes sealed effect, and then food waste drops in tooth fixed part 1 when reducing the meal, influences inside clean and tidy nature.

Preferably, the height of the flexible sheet 5 is 1-2mm, the thickness is 0.3-0.5mm, the height is 1mm or 2mm, and the thickness is 0.3 or 0.5mm, so that the area occupied by the flexible sheet 5 can be effectively reduced, and the sealing effect of the flexible sheet is ensured.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
