Examples

As shown in fig. 1a to 9b, the auxiliary orthodontic device provided in this embodiment is used for performing orthodontic treatment in cooperation with shell-shaped dental appliances such as shell-shaped orthodontic appliances (also called invisible orthodontic appliances) so as to gradually change teeth from initial positions to target orthodontic positions, where the initial positions of the teeth may be initial positions of teeth to be orthodontic treated or positions before any orthodontic treatment in the orthodontic treatment process, and the target orthodontic positions of the teeth may be any positions closer to orthodontic targets than the initial positions; wherein the shell-shaped dental appliance is provided with an accessory accommodating part for matching with the auxiliary correcting device, specifically,

the auxiliary correcting device comprises:

a reference portion capable of being fixed to a tooth surface, an

A correction unit which is extended from the reference unit to a side away from the tooth surface and is used in cooperation with the shell-shaped dental device,

the correcting portion is accommodated at least partially in an attachment accommodating portion of the shell-shaped dental apparatus provided in correspondence with the correcting portion, and,

Specifically, the reference part may be a surface of the auxiliary appliance that is attached to the tooth surface, and is used to attach the auxiliary appliance to the tooth surface; the correcting part has the shape of a conventional accessory matched with the invisible appliance, can realize the function of the conventional accessory, such as fixing the shell-shaped dental appliance, or applying correcting force to teeth by matching the shell-shaped dental appliance, and is also set to have the function of a traditional bracket, so that a fastener, such as an arch wire, can pass through the passage and is fixed on the correcting part through the passage.

The correction part and the accessory containing part are matched with each other to finish corresponding correction effect, and the relation between the outer contour of the correction part and the outer contour of an accessory which can be matched with the accessory containing part to correct teeth is explained, wherein the outer contour of the correction part can be matched with the outer contour of the accessory to correct teeth so as to realize the same correction effect as the accessory; or the outer contour of the correcting part is matched with one part of the outer contour of the accessory, and the matched part generates corresponding correcting force for interacting with the shell-shaped dental corrector; the outer contour of the correction portion may be matched with the outer contour of the attachment, so that the auxiliary correction device further has a correction effect substantially the same as that of the attachment, for example, the attachment is a rectangular attachment, the outer contour of which is matched with the outer contour of the correction portion, and the correction effect generated by the interaction between the rectangular attachment and the shell-shaped dental appliance is also the retention effect generated by the interaction between the correction portion and the shell-shaped dental appliance, so that the correction effects of the correction portion and the attachment are similar or substantially the same; the outer contour of the correction portion may be matched with one part of the outer contour of the attachment, so that the auxiliary correction device further has the same correction function as the attachment, for example, the attachment is a rectangular attachment, only one surface of the attachment which interacts with the shell-shaped dental appliance to generate the correction effect is one surface of the attachment, the auxiliary correction device has the same surface of the attachment which can generate the corresponding correction effect, but the rest part of the auxiliary correction device is different from the outer contour of the attachment, and the same correction effect can also be achieved. The auxiliary correcting device is used for matching with the shell-shaped dental appliance to generate correcting force, and the auxiliary correcting device can be matched with the shell-shaped dental appliance to generate correcting force; in another case, the auxiliary appliance is fitted to the attachment receptacle on the shell-like dental instrument without producing an orthodontic force, and the auxiliary appliance functions as an attachment only for retention of the appliance.

The fasteners are archwires or other components, typically in the form of wires or strips, capable of securing two or more adjacent auxiliary appliances.

In order to enable the auxiliary correcting device to be matched with the fastener to achieve the effect of effectively and uniformly correcting the force and finish the correcting effect on the teeth, the channel on the correcting part of the auxiliary correcting device is not intersected with the reference part, if the channel is intersected with the reference part, the fastener (such as an arch wire) can be caused to be in contact with the surface of the teeth when passing through the channel, the surface of the teeth is abraded and directly subjected to the correcting force applied by the arch wire, the mouth feel discomfort is increased, and after the channel is intersected with the reference part, a channel through hole or a groove can be formed in the reference part, so that the contact area between the reference part and the surface of the teeth is reduced, and the firmness of the auxiliary.

In a preferred structure of the auxiliary correcting device, the channel is a built-in perforation arranged in a proximal-distal direction in the correcting part and/or a groove arranged in a proximal-distal direction on an outer surface of the correcting part.

Referring to fig. 1a and 1b, a structure of the auxiliary orthodontic device 100 is shown. The auxiliary orthodontic device 100 comprises a reference part 101, wherein the reference part 101 is a surface close to the surface of a tooth and can be adhered to the surface of the tooth; the part except the reference part 101 is called a correction part 102, the external shape of the correction part 102 is the shape of a common accessory matched with the invisible appliance, and the correction part can be accommodated or partially accommodated in an accessory accommodating part correspondingly arranged on the shell-shaped dental appliance, so that the auxiliary correction device can be matched with the shell-shaped dental appliance for use. The correction device 102 is provided with a mesial-distal built-in aperture 103 near the center of the clinical crown, the built-in aperture 103 allowing a fastener, such as an archwire, to pass through and enable the archwire to be secured to the auxiliary appliance 100. The built-in through hole 103 does not intersect with the reference portion 101. Through the arrangement of the built-in perforation 103, the arch wire can be arranged on the auxiliary correcting device 100 and exert correcting force on the teeth.

FIG. 2 illustrates another configuration of an auxiliary orthosis 200 having a built-in perforation. The outline is different from that of fig. 1, and is substantially rectangular.

The auxiliary appliances of fig. 1a, 1b and 2 are each contoured to have a height along the long axis of the teeth that is greater than the width along the mesial-distal direction of the teeth, and may be referred to as vertical attachments. Since the channel is selected to be a built-in perforation in each of fig. 1a, 1b and 2, the width in the mesial-distal direction is selected to be relatively small, and the length in the long axis direction of the tooth is selected to be relatively long, so that the processing and manufacturing of the built-in perforation and the penetration of the arch wire can be facilitated. The auxiliary correcting device with the structure can be made of ceramic or metal materials, the vertical position of the accessory can be an anterior tooth zone or a posterior tooth zone, the auxiliary correcting device is adaptively added according to a specific correcting scheme, and the auxiliary correcting device is preferably arranged in the anterior tooth zone and is more suitable for teeth which are relatively long along the length of the long axis direction of the teeth.

Wherein the "posterior dental area" is defined according to the classification of teeth in the 2 nd edition of "introduction to oral medicine" published by Beijing university medical Press, pages 36-38, including premolar and molar teeth, and is represented by FDI notation of 4-8 teeth and FDI notation of anterior dental area is represented by 1-3 teeth. The anterior zone of the shell-shaped dental appliance may be used to accommodate the middle incisors, lateral incisors and cuspids of the upper or lower jaw teeth, and the posterior zone of the shell-shaped dental appliance may be used to accommodate the first premolars, second premolars, first molars, second molars and third molars of the upper or lower jaw teeth.

FIG. 3 illustrates another alternative configuration of the auxiliary orthosis 300, wherein the channel is optionally flanked by proximal and distal grooves 304. In addition, the groove 304 is in an opening shape, so that the arch wire is easy to process and convenient to penetrate. The outer contour of the auxiliary appliance 300 is smaller than the width of the tooth in the direction of the long axis, which can be called as horizontal attachment. Therefore, the width of the auxiliary correcting device arranged along the mesial-distal horizontal direction can be set relatively wide, thereby being suitable for being arranged on teeth with wide mesial-distal directions, such as molars in the posterior teeth area. After the auxiliary correcting device is stuck to the teeth, the area of contact with the arch wire in the near-far direction is larger, and the mutual action of the auxiliary correcting device and the arch wire is more favorable for providing correcting force. The supplementary device of correcting of above-mentioned structure can adopt ceramic or metal material to make, and the level can be for anterior teeth district or posterior teeth district to the position that the annex specifically set up, can carry out adaptability according to concrete correction scheme and add, and preferred setting is in the posterior teeth district.

Fig. 4 a-9 b illustrate several different configurations of auxiliary orthosis with channels selected as simultaneous built-in perforations and grooves in the mesial-distal direction. Set up the advantage of built-in perforation and slot simultaneously and lie in, can realize fixing an arch wire or a plurality of arch wires at first, provide more according to the actual demand of correcting and correct the power and apply the scheme, thereby the arch wire can select more suitable fixed position to pass the arch wire in built-in perforation or slot according to correcting the demand when fixed thereby reaches and corrects the purpose.

The built-in through holes and the grooves may be arranged on different levels, as shown in fig. 4a, 4b, 5a, 5b, 6a, 6b, 8a, 8b, 9a and 9b, or they may be arranged on the same level, as shown in fig. 7.

In the preferred scheme, the built-in through holes and the grooves are arranged in a staggered mode, namely the built-in through holes and the grooves are not in the same horizontal plane, so that the thickness of the auxiliary correcting device along the lip/cheek-tongue side direction is relatively thin, and the foreign body sensation worn by a patient is relieved.

In order to obtain a better distribution of the corrective forces and a suitable strength of the auxiliary corrective device, when the channel comprises an internal perforation, the distance between the internal perforation and the reference portion is preferably not greater than the distance between the internal perforation and the outer surface of the corrective portion.

Taking fig. 4b as an example, the distance between the built-in through hole 403 and the reference part 401 is the distance between the point on the left side of the built-in through hole 403 nearest to the reference part 401 and the surface of the nearest reference part 401, and is marked as a; the distance between the inner perforation 403 and the adjacent labial/buccal side or lingual side (also referred to as the correction outer surface) of the correction portion 402 is the distance between the farthest point of the right side of the inner perforation 403 from the reference portion 401 and the adjacent labial/buccal side or lingual side of the auxiliary appliance, and is marked b. In this case, a is not more than b. More preferably, a ═ b. This is because, when a > b (the left and right orientations are the left and right examples shown in fig. 1a, 1b, 2, 4a to 9 b), the distance between the archwire and the teeth is large when the archwire is passed and the orthodontic force is applied, and the force is likely to be deviated, and in addition, when b is too small, the right side of the auxiliary appliance is damaged when the force is excessively applied, so the optimum design position of the built-in through-hole is at or near the center of the labial/buccal-lingual cross-sectional view.

In order to optimize the correction force scheme and better ensure the strength of the auxiliary correction device, when the auxiliary correction device is provided with the built-in perforation and the groove at the same time, the built-in perforation is arranged at a position closer to the reference part than the groove is arranged, and specifically, the central axis of the built-in perforation is closer to the reference part than the central axis of the groove. On the one hand, the arch wire is more convenient to penetrate through the groove, and on the other hand, the force application is more accurate when the arch wire is penetrated through the built-in through hole.

The cross-sectional shape of the built-in hole of the auxiliary appliance is selected to be a shape suitable for penetration of an arch wire, for example, the cross-section of the built-in hole along the labial/buccal-lingual direction is one of a circle, a semicircle, an ellipse, a semi-ellipse, a polygon or a combination of the above shapes, and the combination of the above shapes refers to a combination shape formed by two or more shapes, for example, a combination of a semicircle and a rectangle. In fig. 1a to 2 and 4a to 9b, the inner holes provided in the auxiliary orthodontic device are all circular, and other shapes or combinations of shapes may achieve the same or similar technical effects, which are not described herein again.
