Description

Tooth appliance

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a dental appliance.

Background

The irregular teeth not only affect the chewing function or the overall beauty, but also cause oral health problems such as tooth decay, periodontal disease or abnormal tooth abrasion of teeth, and seriously cause problems such as alveolar bone, jaw bone or facial deformation; for this reason, more and more people perform orthodontic treatment by making teeth beautiful and healthy.

There are a number of conditions that lead to dental misalignment, the first being: the grown and tidy teeth are lost, and remedial measures such as dental veneering and the like are not taken timely, so that other teeth are loosened, and finally the teeth are not aligned. This is because teeth on both sides of a missing tooth receive a biting force during occlusion of the tooth, and the teeth on both sides are inclined toward a gap formed by the missing tooth, and the teeth to be bitten are elongated, causing a disordered occlusion, further developing a chewing function, and preventing a remedial measure such as a dental insert from being taken for the missing tooth in the future.

The second case is: the inherent deciduous teeth of a user are generally regular, but other deciduous teeth are loosened due to the missing of the deciduous teeth in the tooth replacing period, so that the width of the tooth gaps among the deciduous teeth is smaller than that of the permanent teeth to be grown, and the permanent teeth are extruded by the deciduous teeth, so that the permanent teeth are askew, the teeth are further uneven, and if the situation is serious, the normal development of alveolar bones and jaw bones of the user can be influenced.

The third case is: the congenital deciduous teeth of the user cause the permanent teeth with long tooth replacement period to be influenced by factors such as deciduous tooth extrusion, alveolar bone or jaw bone, and the like, so that the permanent teeth are inclined to cause the teeth to be irregular.

In view of the first problem, a conventional solution is to make a user with missing teeth perform a remedial measure such as setting or implanting teeth as soon as possible, but if the user with missing teeth cannot perform the remedial measure such as setting or implanting teeth timely due to other reasons, the teeth may be misaligned, and the existing technical means only corrects the teeth when the teeth are misaligned, and cannot prevent the misaligned teeth which are grown and arranged orderly due to missing teeth.

In view of the second and third problems, the conventional technique generally corrects teeth after they are grown, and usually corrects teeth by adhering an orthodontic wire to each tooth surface, attaching an orthodontic wire to each orthodontic wire, and pulling the orthodontic wire to change the arrangement position of the teeth, thereby changing the overall appearance of the teeth and changing the malocclusion. However, the above-described technical means for straightening teeth requires a user to wear the device for a long period of time, and food residues are easily left around the device, resulting in problems such as long straightening cycle, poor appearance, and unsanitary conditions. And the above-mentioned existing orthodontic techniques cannot prevent the user and the adult from having the misaligned teeth. Therefore, the existing orthodontic technology cannot fundamentally solve the problems of tooth length distortion and tooth arrangement irregularity.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather construed as limited to the embodiments set forth herein.

The present application provides an appliance for teeth. The dental appliance of the present invention will be described in detail with reference to the following specific embodiments and accompanying drawings.

In daily life, there are many cases where teeth have grown to have gaps between teeth, for example: the teeth that have grown up may have gaps between teeth due to missing teeth, as shown in fig. 1, and fig. 1 is a schematic view showing the deformation of teeth when a user has missing teeth. Or the dental caries, the gap formed after the bacteria erode the teeth, etc.; there are many cases of tooth gaps occurring in the grown teeth, and the description thereof is omitted here. The application provides a tooth unscrambler sets up tooth clearance and accounts for a position piece corresponding to tooth clearance position to promote the orthodontic effect of tooth unscrambler.

Fig. 2 is a schematic view of an orthodontic appliance in accordance with a first embodiment of the utility model.

As shown in fig. 2, the dental appliance 1 of the present embodiment includes a orthodontic shell 12 and an interdental space occupying block 13. Wherein the orthodontic braces 12 constitute a main body portion of the dental appliance 1, which may also be referred to as a dental appliance body; in this application, the orthodontic appliance is used to refer to the entire orthodontic shell provided in this embodiment including the tooth space occupying block 13, and the orthodontic shell is specifically referred to the body portion of the orthodontic appliance excluding the tooth space occupying block, which is referred to merely for convenience of expression.

The orthodontic braces 12 are specifically modeled and customized according to the use requirements of a specific user and comprise grooves 121, inner groove walls 122 and outer groove walls 123, wherein the grooves 121 are made according to the positions, shapes and sizes of the teeth of the user to form an overall inner contour matching the overall shape of the teeth of the user, and the surface of the inner contour is the inner groove walls 122. The outer walls 123 of the channels form the outer surface of the orthodontic braces 12 for aesthetic purposes and to minimize the use of teeth.

The dental appliance is also provided with a tooth space occupying block 13. The tooth space occupying block 13 is arranged in the groove 121 of the orthodontic brace 12, the specific arrangement position of the tooth space occupying block is correspondingly arranged according to the tooth space position of a user, the shape and the size of the tooth space occupying block 13 are arranged according to the shape and the size of the tooth space corresponding to the tooth space occupying block 13, and when the user wears the orthodontic appliance 1, the tooth space occupying block 13 enters and occupies the corresponding tooth space.

There are various causes of the generation of the tooth space, and generally, the occupation block is mainly provided in the tooth space formed by the tooth loss caused by various causes. The gap occupying block 13 provided in the orthodontic braces 12 shown in fig. 2 is formed for the missing tooth and thus has a contour shape and a size similar to those of the missing tooth, and of course, the gap occupying block 13 is not required to be perfectly complementarily fitted to the contour of the gap caused by the missing tooth because it is difficult to be technically achieved, and the gap occupying block 13 is required to be conveniently inserted into the space of the gap between the teeth when the orthodontic braces 12 are worn and is made to be exactly fitted in size, which makes the orthodontic braces 12 difficult to wear; on the other hand, if the profile of the gap occupying block 13 is too different from the gap, the correction effect is affected; therefore, the size and profile design of the gap occupying block 13 should take into consideration the contradiction between the above two aspects and select an appropriate intermediate parameter.

The first embodiment is mainly directed to a case where a user whose teeth have grown needs to wear the dental appliances due to missing teeth. Although the teeth of the user are regularly arranged, when the user cannot insert or implant teeth in time due to some reasons, in order to avoid the situation that the teeth of the user start to deform from the gaps between the teeth due to the loss of the teeth, the user needs to wear the dental appliance 1, and at this time, the grooves 121 may be arranged according to the position, shape and size of each tooth of the user, so that the inner wall 122 and the outer wall 123 of each groove are fitted to each tooth of the user. The tooth gap occupying block 13 can be just contacted with teeth on two sides of the tooth gap, so that the situation that the teeth are deviated towards the tooth gap direction due to the action of force between the teeth in the process of waiting for tooth setting or tooth planting of a user is avoided.

Optionally, the number of the tooth space occupying blocks 13 is one or more. For example: when only one tooth space needing to be occupied in the teeth of the user is available, the tooth space occupying block 13 on the dental appliance is correspondingly set to be one. When there are a plurality of tooth gaps needing to be occupied in the teeth of the user, the tooth gap occupying block 13 on the dental appliance is correspondingly set to be a plurality.

When the teeth of the user are uneven, the grooves 121 can be arranged according to the specific positions of the unevenly arranged teeth, the inner wall 122 or the outer wall 123 of each groove can provide proper acting force to the unevenly arranged teeth so that the unevenly arranged teeth deviate towards the orderly arrangement direction, at the moment, the tooth space occupying block 13 on the dental appliance 1 occupies the tooth space of the user, and the tooth space occupying block 13 can be just contacted with the teeth at two sides of the tooth space, so that the situation that the teeth deviate towards the tooth space direction due to the action of the force between the teeth in the process of correcting the teeth of the user is avoided. Therefore, in the process of straightening teeth, the teeth of the user cannot shift towards the direction of the gaps between the teeth due to the action of the space occupying blocks between the teeth, and at the moment, the unevenly arranged teeth can move towards the direction in which the teeth are arranged orderly under the action of the force of the inner wall 122 or the outer wall 123 of the groove, so that the tooth roots of the teeth of the user can also move towards the direction in which the teeth are arranged orderly in the process of straightening the teeth of the user, the condition that the teeth of the user are distorted in the process of growing the teeth is effectively prevented, and the problems of tooth distortion and tooth arrangement are fundamentally solved.

Alternatively, the grooves 121 may be directly formed at positions where the teeth are aligned when the teeth are positioned closer to the aligned positions, and at this time, the user can correct the misaligned teeth using one dental appliance. When the misaligned teeth are far from the teeth-aligned position, the teeth may be gradually aligned using a plurality of different orthodontic appliances 1, the grooves 121 of which are the orthodontic appliances that are closer to the teeth-aligned position, and the number of the different orthodontic appliances may be 2, 3, or N according to the teeth-aligned condition of the user. The user may gradually replace the plurality of different appliances during the orthodontic procedure such that the user's teeth are closer and closer to the position where the teeth are aligned until the teeth are aligned.

Optionally, the tooth space occupying block and the orthodontic braces may be formed at one time by a 3D printing technique or a similar technique, or the tooth space occupying block and the orthodontic braces may be connected by an anchoring process.

Optionally, the material of the orthodontic tooth socket comprises resin or elastic high polymer material.

In the second embodiment, when the user is in the tooth replacing period, the tooth gap can also be a gap between deciduous teeth of the user or a gap formed by the falling of deciduous teeth when the user is in the tooth replacing period, in this case, the dental appliance sets the tooth gap occupying block 13 according to the gap between the deciduous teeth of the user and the gap formed by the falling of the teeth, and the tooth gap occupying block 13 is correspondingly and matchedly set according to the position, the shape and the size of the tooth gap of the tooth to be corrected. When the dental appliance 1 is worn, the tooth space occupying block 13 just enters and occupies the corresponding tooth space. And the tooth space occupying block 13 is not in contact with the gum of the user. If the teeth of the user in the tooth replacement stage that erupt at the teeth are misaligned,

the grooves 121 can be designed according to the specific positions of the unevenly arranged teeth, so that the inner wall 122 or the outer wall 123 of the groove can provide proper acting force to the unevenly arranged teeth, so that the unevenly arranged teeth deviate towards the orderly arrangement direction, at the moment, the tooth space occupying block 13 on the dental appliance 1 occupies the tooth space of the user, the tooth space occupying block 13 can be just contacted with the teeth at two sides of the tooth space, and the situation that the teeth deviate towards the tooth space direction due to the action of the force between the teeth in the process of straightening the teeth of the user is avoided. Therefore, in the process of straightening teeth of the user, the teeth are not shifted in the direction of the gaps between the teeth due to the function of the space occupying blocks, and at this time, the misaligned teeth are moved in the direction in which the teeth are aligned by the force of the inner wall 122 or the outer wall 123 of the groove, and the roots of the teeth are also moved in the direction in which the teeth are aligned, so that the jaw bone of the user is also aligned.

Alternatively, when the misaligned teeth are closer to the aligned position, the tooth grooves 121 may be directly formed at a position where the teeth are aligned, and at this time, the user may correct the misaligned teeth using one dental appliance. When the misaligned teeth are far from the teeth alignment position, a multi-stage orthodontic appliance 1, which is an orthodontic appliance in which a plurality of tooth grooves 121 are closer to the teeth alignment position, may be used, and the number of the multi-stage orthodontic appliances may be 2, 3, or N according to the tooth alignment condition of the user. The multi-stage dental appliance may be gradually replaced by the user during the orthodontic procedure to bring the user's teeth closer and closer to the position where the teeth are aligned until the teeth are aligned. When tooth clearance position occupying block 13 is in the position in the clearance that the tooth dropped the production, the tooth clearance position occupying block in this position can cut according to eruption tooth growth height to avoid with eruption tooth contact. So that the growth of erupting teeth is not affected. And when the user in the tooth replacement period uses the dental appliance 1, the gaps between the teeth of the user can be effectively managed, and the situation that the lateral deciduous teeth are extruded due to the fact that the size of the erupted teeth is larger than that of the original deciduous teeth is avoided. Further effectively corrects the teeth of the user in the tooth replacement period, effectively prevents the user from having the condition of tooth skewness in the tooth growth process, and further fundamentally solves the problems of tooth skewness and tooth arrangement.

Optionally, work as when tooth clearance placeholder block 13 is in the position in the clearance that the tooth dropped the production, the user can carry out the adaptability cutting according to eruption tooth growth progress, makes the placeholder block can not contradict with user's eruption tooth to can not influence eruption tooth's growth.

Optionally, work as when tooth clearance position block 13 is in the position in the clearance that the tooth dropped the production, tooth clearance position block 13 in this position sets up layered structure, and the user can highly demolish the layering towards eruption tooth according to eruption tooth growth, and the number of piles of demolising can make tooth clearance position block 13 can not with eruption tooth is contradicted to can not influence eruption tooth's growth.

Optionally, the connection mode of the layered structure of the tooth space occupying block 13 includes connection in a layer-by-layer nested manner, and the specific mode of the layer-by-layer nested connection is that a protrusion is arranged on the groove 121 of the orthodontic braces 12 and at a position corresponding to the tooth space of the user, and a groove matched with the protrusion and a protrusion matched with the groove are respectively arranged on both sides of each layer of the tooth space occupying block with the layered structure, so that the tooth space occupying block with the layered structure is connected layer by layer in a nested manner.

Optionally, the connection mode of the tooth space occupation block 13 in the layered structure includes connection by a layer-by-layer screwing mode, as shown in fig. 3, in this embodiment, the number of layers of the tooth space occupation block is three, and the layer-by-layer screwing mode with three layers is specifically that a threaded blind hole 1211 is arranged on the slot 121 of the orthodontic braces 12 and at a position corresponding to the tooth space of the user, a stud 1312 matched with the threaded blind hole 1211 on the slot 121 is arranged on one side of the first layer of tooth space occupation block 131 facing the slot 121, when the stud 1312 of the first layer of tooth space occupation block 131 is screwed with the threaded blind hole 1211 of the slot 121, the first layer of tooth space occupation block 131 is just attached to the slot 121, and a stud 1311 matched with the thread 1311 on the first layer of tooth space occupation block 131 is arranged on one side of the second layer of tooth space occupation block 132 facing the first layer of the layered structure and facing the first layer of tooth space occupation block 131 When the studs 1322 of the second layer of tooth space occupying block 132 are screwed with the threaded blind holes 1311 of the first layer of tooth space occupying block 131, the second layer of tooth space occupying block 132 is just attached to the first layer of tooth space occupying block 131, one side of the third layer of tooth space occupying block 133 with a layered structure, which faces the second layer of tooth space occupying block 132, is provided with studs 1332 matched with the threaded blind holes 1321 of the second layer of tooth space occupying block 132, and when the studs 1332 of the third layer of tooth space occupying block 133 are screwed with the threaded blind holes 1321 of the second layer of tooth space occupying block 132, the third layer of tooth space occupying block 133 is just attached to the second layer of tooth space occupying block 132.
