Description

Tooth Movement Accelerator {ORTHODONTIC TOOTH MOVEMENT ACCELERATOR}

The present invention relates to a tooth movement accelerator which is a kind of orthodontic device.

Conventionally, as an orthodontic apparatus, what has a wire attached to a tooth is widely used. The elastic restoring force of the wire acts as a constant static load on the teeth, thereby correcting tooth alignment and occlusion. That is, the orthodontic appliance is based on the principle that when a certain force is applied to the teeth, the alveolar bone supporting the teeth in the gums is gradually deformed (bone remodeling, bone remodeling), thereby correcting the orthodontics.

However, orthodontics using the wires require a very long period of time to complete cure (as early as six months, usually several years). In order to shorten the period of the orthodontic treatment, various methods such as self-ligation brackets for reducing the frictional force of the brackets and rapid orthodontic surgery with minor surgery have been attempted. In addition, a drug injection method and the like have also been attempted to improve tooth movement speed experimentally.

 Among them, techniques such as giving a vibration to the teeth to increase the speed of tooth movement by increasing the number of bone fracture cells around the teeth by giving a fine vibration to the teeth are being studied.

According to this study, the application of the vibration force to the dental dentition drastically shortens the period of the orthodontic treatment to about 1/2 to 1/3 of the related art. From these studies, it can be understood that an orthodontic appliance that gives a vibration force in addition to the orthodontic force is more effective in the drastic shortening of the orthodontic period than an orthodontic correction that only provides a constant orthodontic force to a tooth with a wire or the like.

Conventionally, an apparatus for practical use of the above research has been proposed. Specifically, Patent Document 1, as shown in Fig. 1, to provide ultrasonic vibration to the mouthpiece (7) attached to the teeth to promote the movement of the teeth to be corrected, and the surrounding tissue of the mounting portion of the mouthpiece An orthodontic appliance having means 8 is disclosed.

In addition, Patent Document 2, as shown in Fig. 2, the headpiece lying on the pillow 70 placed in the support 60 with the head, and then connected to the mouthpiece 30 by the calibration pin 40 groove 31 After the door is inserted so that the upper teeth are inserted into the teeth, the controller 11 provided in the vibration generating means 10 operates to generate vibrations so that teeth grown to an incorrect position can be corrected so that the teeth 80 can be returned to their positions. An apparatus is disclosed.

In patent document 3, as shown in FIG. 3, the orthodontic plate 23 is connected to the external vibration means 21, and the vertical part or the corner parts 29 and 31 of the orthodontic plate 23 are the face of a tooth. Disclosed is a vibrating dental instrument which is shaped to be in contact with a side or a lingual side, and which makes it possible to maximize its vibration during use.

 However, the apparatus described in Patent Documents 1, 2, and 3 affects teeth that do not need to move during orthodontic treatment, and has been inconvenient to use due to various problems such as fatigue of masticatory muscles and difficulty in treating saliva in the oral cavity because of a 20-minute biting. .

In addition, the patent documents 1, 2 3 had the inconvenience of separately manufacturing a mouthpiece for each patient's dentition.

A slight gap is formed between the groove 164 and the hollow portion 163 of the vibrating portion and the protrusion 112 of the main body end 111 so that the vibration of the vibrating portion is not transmitted to the end 111 of the main body. desirable. Since the protrusion 112 must be pressed in order to detach the vibrator from the vibrating shaft, the vibrator and the vibrating shaft are prevented from being accidentally separated, and the vibrating portion can be easily coupled and separated from the vibrating shaft.

In another exemplary embodiment of the present invention, as shown in FIG. 6, only the hollow part 163 is formed at one end of the vibrating part, and the main body 110 has only one end 111 having a through hole through which the vibration shaft passes. Formed. The end 111 is inserted into the hollow part 163, and a slight gap is formed between the hollow part and the end so that vibration of the vibrating part is not transmitted to the end of the main body. Therefore, in the present invention, the vibration unit can be easily coupled and separated from the main body.

 Hereinafter, the method of use of the present invention will be described.

In the present invention, the dentist or the patient directly lifts and contacts the elastic body of the head to the tooth or gum in the same direction as the moving direction of the tooth. After that, the ON / OFF switch is operated to supply power to the vibration motor to generate vibration.

 The vibration motor increases or decreases the rotation speed to apply vibration of the appropriate size to the teeth.

 By using the present invention, by applying the vibration force to the tooth through the elastic body that touches the tooth and this force induces the formation of osteoclasts in the root portion of the tooth to induce tooth movement faster than the normal tooth movement speed by the corrective force do.

When the elastic body needs to be replaced by long time use in the present invention, the entire vibrating part including the elastic body may be replaced, or only the elastic body may be replaced by rotating a male screw of the elastic body.
