Description

Correcting device with adjustable torque direction

Technical Field

The utility model relates to the technical field of orthodontic appliances, in particular to an orthodontic device with an adjustable torque direction.

Background

Currently, orthodontists generally treat patients with teeth or faces with orthodontic appliances, such as brackets, buccal tubes, etc., for example, aiming at the problems of crowding, bucking, uneven tooth arrangement, malocclusion, etc. During conventional orthodontic treatment, an orthodontist attaches a bracket or buccal tube to the surface of a patient's teeth and places an archwire into the archwire slot of the bracket through which the archwire applies corrective forces to the teeth to move the teeth into the correct position. Orthodontic appliances are typically made of metal and are applied to the teeth to affect aesthetics, so some patients choose to apply orthodontic appliances to the lingual side of the teeth for aesthetic purposes during treatment.

The patent application CN113876450A discloses an easy-to-adjust correcting device, which comprises an arched member, a fixing member and an elastic piece, wherein the elastic piece comprises a first connecting end, a middle section and a second connecting end which are sequentially connected, the first connecting end is detachably connected with the fixing member, the second connecting end is detachably connected with the arched member, at least one of the first connecting end and the second connecting end is provided with at least two connecting gears, and the connecting gears are arranged at intervals along the gingival and jaw direction or the near-far-middle direction. When the correction force is required to be enhanced, the elastic piece can be broken more tightly by replacing the elastic piece with the connecting gear which is closer to the middle section, so that the correction force is stronger, the elastic pieces with different thicknesses are not required to be produced, and the connecting gear is replaced.

The related terms labial, lingual, mesial, distal, occlusal and gingival are industry terms for orthodontic treatment. Taking a certain tooth of the upper jaw as an example, the surface of the tooth may be roughly divided into six faces. The surface of the tooth which is occluded with the mandibular tooth is an occlusal surface; the face of the tooth to which the attached gingival tissue is attached is the gingival face; the occlusal surface is opposite to the gingival surface, and the direction in which the occlusal surface is formed is also called the gingival-jaw direction. The face of the tooth facing the lip is a labial face, the face of the tooth facing the tongue is a lingual face, the labial face and the lingual face are opposed to each other, and a direction in which the labial face and the lingual face are formed is also called a labial-lingual direction. The two surfaces of the tooth which are in contact with the adjacent tooth are a mesial surface and a distal surface, respectively, which are different in that the distance from the middle is far and near, and the direction in which the two surfaces are formed is also called a mesial-distal direction or a mesial-distal direction.

And in the description of directions, such as the labial and lingual directions, are commonly referred to as bi-directional. And, as the labial-lingual direction, a single direction is specifically referred to as the direction from the labial side to the lingual side, and is distinguished.

Example 1

Referring to fig. 1 to 5, the torque direction adjustable orthotic device 100 (hereinafter abbreviated as orthotic device 100) in embodiment 1 can be adjusted in the torque direction. The term "adjustable in torque" as used herein means that the torque direction of the tooth to which the fixing member 120 is attached is adjustable, that is, the direction of rotation about the mesial-distal direction.

Specifically, when one of the teeth needs to be adjusted in the torque direction, the first connecting end 131 can rotate relative to the fixing member 120 in the torque direction, after reaching the optimal position, the first connecting end 131 and the fixing member 120 are locked, the first connecting end 131 and the fixing member 120 can not rotate relatively at the moment, the first connecting end 131 of the elastic piece 130 applies a force in the torque direction to the fixing member 120, and then the force is transmitted to the tooth, so that the tooth rotates in the torque direction, the tooth correcting efficiency of the correcting device 100 is effectively improved, and the correcting effect is ensured.

Specifically, the number of the arcuate members 110 may be one, the number of the fixing members 120 may be plural, one fixing member 120 may be attached to one tooth surface, the number of the elastic pieces 130 may correspond to the number of the fixing members 120, the first connection ends 131 of the elastic pieces 130 may be rotated in the torque direction with respect to the fixing members 120, and the adjustment of the teeth to which the fixing members 120 are attached in the torque direction may be enabled.

Or, the mating portion is a square column (for example, a square column or a hexagonal column, etc.), the mating hole is a square hole (for example, a square hole or a hexagonal hole, etc.), when the mating portion and the mating hole need to be adjusted, the mating portion is taken out from the mating hole, then the mating portion is rotated to an angle, and after reaching the target angle, the mating portion is inserted into the mating hole, and locking is achieved through the side wall.

Referring to fig. 2-5, the second link 133 is rotatable relative to the arcuate member 110 in a rotational direction for effecting adjustment of the teeth in the rotational direction.

Referring to fig. 16 to 18, in embodiment 5, the correction device 500 is substantially the same as that of embodiment 4, and the main difference is the connection manner between the first connection end 531 of the elastic member 530 and the fixing member 520. In embodiment 5, the first connection end 531 is rotatable in a rotational direction relative to the fixing member 520 for achieving adjustment of teeth in the rotational direction.

Specifically, the first connecting end comprises a rotating part, a rotating hole is formed in the fixing member, the rotating hole extends along the gingival and jaw direction, the rotating part is inserted into the rotating hole, and locking is achieved between the rotating part and the rotating hole through extrusion force between the side wall of the rotating part and the side wall of the rotating hole. For example, the rotating portion is substantially in the shape of an elliptic cylinder, and the corresponding rotating hole is substantially in the shape of an elliptic cylinder, and the pressing force of the rotating portion against the rotating hole is also changed during the rotation of the rotating portion relative to the rotating hole, so that the locking between the rotating portion and the rotating hole can be achieved.

Example 6
