Technical Field

The utility model relates to a technical field is rescued to the tooth, more specifically says, the utility model relates to a ware is rescued to tooth of polygon cylinder annex.

Background

With the gradual development of the bracket-free invisible orthodontic technology, the invisible orthodontic device has the characteristics of convenient taking and wearing, easy clinical use, being beneficial to sanitary cleaning of oral cavity and the like, so that the bracket-free invisible orthodontic technology is more and more popular; in the process of straightening teeth, the integral movement and the root control movement of the teeth are always the difficulty of the invisible straightening technology.

At present, the requirement of overall movement during correction is that the tooth crown and the tooth root of a tooth move together towards a target position and the moving distances are the same, but the tooth root in the prior art is interfered by periodontal tissues, so that the overall movement is not uniformly stressed, the overall movement cannot be realized, and finally the overall correction regularity of the tooth is reduced, and therefore improvement is needed.

Moreover, the requirement of root movement during tooth correction is that the tooth root rotates in the mesial-distal plane by taking a proper point (generally, a center of mass) of the tooth crown as a center, so as to adjust the incisal margin of the tooth crown and enable the incisal margin to be matched with incisal margins of other teeth to form a perfect incisal margin plane; however, in the oral cavity structure of a human body, the tooth crown of the tooth is a free end, the tooth root is a fixed supporting end, the tooth crown is required to be ensured not to move or to move little, and the tooth root rotates, so that a new supporting point needs to be artificially manufactured for the tooth crown, and the tooth root is a free end.

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. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the utility model provides a tooth appliance with polygonal column attachments, which comprises an appliance body 1, wherein the bottom of the appliance body 1 is provided with a plurality of mutually connected positioning cavities 2, the positioning cavities 2 are sleeved outside teeth, the upper ends of the inner cavities of the positioning cavities 2 are provided with attachment clamping grooves 3, the attachment clamping grooves 3 are internally sleeved with appliance attachments 4, the inner sides of the appliance attachments 4 are embedded into the teeth, the positioning cavities 2 are in one-to-one correspondence with the teeth, the size of the inner cavity of each positioning cavity 2 is matched with the size of a corresponding tooth, and the edge of the appliance attachment 4 is provided with a torsion slip surface 5;

the attachment can be conveniently carried out on the tooth long shaft, and compared with the prior art that the symmetry of the attachment and the relation between the attachment and an impedance center need to be considered, the attachment difficulty is increased; meanwhile, as the polygonal accessory is provided with a plurality of activating surfaces and auxiliary surfaces, the activating surfaces and the auxiliary surfaces can exchange roles and exchange functions in the correction process; the number of times and the number of attachments can be effectively reduced for complex movements.

The sizes of the positioning cavities 2 are not completely the same, and each positioning cavity 2 is the same as the shape of a corresponding tooth;

the expected correction effect on each tooth can be ensured through the plurality of different positioning cavities 3, so that the integral correction effect of the teeth is further improved.

Wherein, the inner wall of location cavity 2 is smooth, communicates each other between the adjacent location cavity 2.

Wherein the outer surface of the appliance body 1 is smooth, and two sides of the appliance body 1 are respectively attached to the lingual side and the labial side of the dental crown;

the smooth surface of the appliance 1 can reduce the damage to the tongue side and the lip side, and meanwhile, the comfort of wearing can be improved due to the fact that the appliance 1 is attached to the tongue side and the lip side.

As shown in fig. 4, the orthodontic accessory 4 belongs to a polygonal column, and the torsion slip surface 5 is a plurality of activating surfaces and auxiliary surfaces;

the shape of the orthodontic accessory is but not limited to that in the drawings, the orthodontic accessory can effectively resist the resistance formed by periodontal tissues, and the activating surface and the auxiliary surface of the accessory can be exchanged in function at any time.

The utility model discloses a theory of operation and use flow:

in the first embodiment, the positioning sleeve 2 can generate the correcting force after being forcibly deformed, and the corresponding teeth 4 are promoted to move through the positioning cavities 3, wherein the positioning sleeve 2 and the correcting accessories 5 are matched with each other to generate the correcting force acting on the dental crowns and the accessories; the cavity formed by the appliance 1 at the target tooth therefore contains an attachment, i.e. the inner wall of the positioning cavity 3 at the location of the attachment forms a cavity conforming to the shape of the surface of the appliance 5; the orthodontic attachment 5 is now fixed onto the tooth; the shape of the correction accessory 5 can be one of polygonal columns such as a pentagonal column, a hexagonal column, a heptagonal column and an octagonal column, and a geometric body formed by rounding each side of the column;

in the second embodiment, after the orthodontic attachment 5 is fixed on the teeth, the appliance can be assisted to cause the teeth to move, and when the orthodontic attachment 5 causes the teeth to start to move, a plurality of activating surfaces participate in orthodontic force action, so that the teeth are driven to move; when the teeth move, the periodontal ligament environment generates resistance to the root of the teeth, and the correction force generated by the matching of the correction device and the correction accessory 5 can effectively offset the resistance, so that the dental crowns and the tooth roots stably and consistently move to the target position;

the third embodiment, when correcting appliance 1 and correcting annex 5 cooperation use, can effectually resist the resistance that the periodontal tissue formed to the tooth removal, the power direction is corrected and is clear and definite and stable to the production, and the tooth receives this effect of correcting, and the removal effect obviously improves, and the apex direction when toppling over danger when having avoided whole removal and accuse root to remove is difficult to confirm effectively.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
