Description

Technical Field

[0001] The utility model relates to the technical field of invisible orthodontic appliances, in particular to paired auxiliary nails for invisible orthodontic appliances without brackets. Background Art

[0002] As people pay more and more attention to aesthetics, they not only have requirements for the neatness of teeth, but also begin to have requirements in the selection of braces. Therefore, people are not limited to choosing traditional fixed orthodontic appliances composed of nickel-titanium alloy archwires and metal brackets. More and more people choose invisible braces without brackets that are beautiful, comfortable and easy to remove.

[0003] Bracketless invisible braces are one of the cutting-edge technologies in the field of orthodontics. Their correction force comes from the rebound force generated by the deformation of the hot-pressed film material, which is equivalent to the rebound force brought by the traditional nickel-titanium alloy. However, bracketless invisible braces lack the auxiliary devices used in traditional brackets. The force exerted on the teeth by invisible bracketless braces is often given to the reaction force of braces in the form of accessories to assist the movement of teeth. However, the movement of teeth includes tilting movement, overall movement, vertical movement, torque movement and rotational movement. The role of accessories alone is far from enough.

[0004] There is an urgent need for paired auxiliary pins for bracketless invisible orthodontic appliances to solve the technical defects raised in the above-mentioned technology. Utility Model Content

[0005] The purpose of the utility model is to provide a pair of auxiliary pins for a bracketless invisible orthodontic appliance, so as to solve the problem in the above-mentioned background technology that the auxiliary parts cannot assist the tooth movement in multiple directions.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pair of auxiliary pins of a bracketless invisible orthodontic appliance, comprising an invisible orthodontic appliance main body, wherein a first cone-shaped auxiliary pin and a second cone-shaped auxiliary pin are respectively arranged inside the invisible orthodontic appliance main body, a third cone-shaped auxiliary pin is arranged on the side of the second cone-shaped auxiliary pin, four groups of fourth cone-shaped auxiliary pins are arranged at the molars of the invisible orthodontic appliance main body, and the four groups of the fourth cone-shaped auxiliary pins are distributed at the four corners of the labial side of the molars, four groups of sixth cone-shaped auxiliary pins are arranged at the molars of the invisible orthodontic appliance main body, and the four groups of the sixth cone-shaped auxiliary pins are distributed at the four corners of the buccal and lingual sides of the molars, and a fifth cone-shaped auxiliary pin is arranged at the incisors of the invisible orthodontic appliance main body.

[0007] Preferably, the first cone-shaped auxiliary pin is located at the incisor and away from the gum side.

[0008] Preferably, the second conical auxiliary pin is located on the side of the incisor.

[0009] Preferably, the third cone-shaped auxiliary pin is located at the front teeth and close to the lip side.

[0010] Preferably, the fourth conical auxiliary pin is located at the molar and close to the gap between the teeth.

[0011] Preferably, the fifth cone-shaped auxiliary pin is located at the front teeth and is arranged at a position close to the tongue side.

[0012] Compared with the prior art, the beneficial effects of the utility model are: the paired auxiliary pins of the bracketless invisible orthodontic appliance not only realize the function of assisting tooth movement in all directions, but also realize the function of enhancing wearing comfort;

[0013] By providing a first cone auxiliary pin, a second cone auxiliary pin, a third cone auxiliary pin, a fourth cone auxiliary pin, a fifth cone auxiliary pin and a sixth cone auxiliary pin, pairs of cone auxiliary pins are formed at corresponding positions in the bracketless orthodontic appliance. The interaction force generated by the positive torque generated by the pairs of auxiliary pins has a good effect on the inclination movement, overall movement, vertical movement, torque movement and rotational movement of the teeth. For example, the third cone auxiliary pin and the fifth cone auxiliary pin can assist the overall movement of the incisors, and the fourth cone auxiliary pin can assist the inclination movement of the molars, etc., which facilitates and optimizes the integration of the auxiliary device and the bracketless orthodontic appliance, improves the convenience of bracketless correction, and further improves the correction effect. Generally, in tooth extraction cases, the mesial inclination movement of the posterior teeth is prevented, and the sixth cone auxiliary pin applies the distal inclination force of the tooth axis. When the molars move distally, the distal inclination of the teeth is prevented, and the mesial inclination force of the tooth axis is applied. BRIEF DESCRIPTION OF THE DRAWINGS
