Description

Technical Field

[0001] The present invention relates to devices for dentofacial correction, which is part of the science of orthodontics. In particular, the present invention relates to bone ossification or bone modeling, which will help improve the results of orthodontic treatment. Background Art

[0002] In the past, maxillary expanders were specialized devices used to treat dental and maxillary abnormalities in patients with mandibular protrusion and maxillary hypoplasia. The device was used to pull the maxilla and teeth forward to properly align the upper teeth with the lower incisors and improve the angle. The current devices used to treat maxillary abnormalities are called traction headbands or masks.

[0003] Figure 1 and 2 Popular previous inventions, namely Dr. DeLaire's traction headband and Dr. Petit's face mask, are shown separately. These devices work in the same way, by pulling the bones and teeth forward. Each device consists of two components, including: an intraoral acrylic plate secured with all upper teeth, which consists of two hooks attached to teeth No. 16 and 26, and an extraoral tool with pressure supports on the chin and forehead, which consists of a bent metal piece connected with a horizontal metal strip or hard plastic piece to reinforce the module.

[0004] Previous devices were large and difficult to wear. They required multiple steps to put on and take off, and could easily fall off during sleep. Additionally, these devices can be unsightly and noticeable, and users may feel uncomfortable talking and wearing them in public. As a result, these limitations can hinder daily activities and may result in prolonged treatment duration. Summary of the invention

[0005] The object of the present invention is to create an intraoral orthodontic device to enhance maxillary expansion and to create a smaller, lighter, easier to wear and less noticeable device that is more effective and reduces treatment time without causing any discomfort to the oral area.

[0006] The orthodontic device for pulling the upper incisors to achieve facial balance comprises two main devices connected to the patient's teeth. The first device (1) comprises an upper plate (5) located behind the six upper incisors and firmly fixed with an orthodontic adhesive, and a first hook (3) and a second hook (4) made of stainless steel spring hard wire are adhered to both ends of the upper plate (5).

[0007] The second device (2) includes a right plate (6) and a left plate (7) covering the remaining posterior teeth and partially covering the upper jaw, a first wire (8) as a stainless steel spring hard wire is connected to the right plate (6) and the left plate (7), and a second wire (9) as a stainless steel spring hard wire is bent along the front teeth. In the central incisor area, a third hook (10) and a fourth hook (11) are provided. The second wire (9) in the premolar area is made into a left U-shaped loop (12) and a right U-shaped loop (13), and both ends of the wire are connected to the right plate (6) and the left plate (7).

[0015] An orthodontic device for pulling upper incisors to achieve facial balance according to the present invention comprises two main devices: a first device (1) and a second device (2). The first device (1) comprises an upper plate (5) located behind six upper incisors and firmly fixed with an orthodontic adhesive, and a first hook (3) and a second hook (4) are connected to the upper plate (5).

[0016] The first hook (3) and the second hook (4) have a diameter of 0.5-1.2 mm and a height of 10-17 mm, and each of them is connected to the upper plate.

[0017] The second device (2) includes a right plate (6) and a left plate (7) located on both sides of the upper jaw and covering all the posterior teeth. On the lingual side, the right plate (6) and the left plate (7) are aligned with the upper jaw, each plate is 10-15 mm away from the center of the upper jaw, and the first wire (8) is connected to the right plate (6) and the left plate (7), which is a stainless steel spring hard wire with a diameter of 0.6-1.3 mm.

[0018] The second wire (9), which is a stainless steel spring hard wire with a diameter of 0.6-1.3 mm, is bent along the upper incisors. The front part of the wire forms a third hook (10) and a fourth hook (11). The second wire (9) bent along the premolars is made into a left U-shaped loop (12) and a right U-shaped loop (13) with a width and height of 3-10 mm, and both ends of the wire are connected to the right plate (6) and the left plate (7).

[0019] The height of the third hook (10) and the fourth hook (11) is preferably 4-12 mm. The two ends are opposite to each other. The distance between the two hooks is 10-17 mm.

[0020] The upper plate (5), the right plate (6) and the left plate (7) can be selected from acrylic plates or transparent plastic plates.

[0021] The function of the orthodontic device for pulling the upper incisors to achieve facial balance according to the present invention starts with installing the first device (1) on the upper incisors with an orthodontic adhesive. Then, before placing the right plate (6) and the left plate (7), the second wire (9) is placed at the upper incisors to install the second device (2), which is easier. Take a 1 / 8 inch 3.5 ounce elastic or a 3 / 8 inch 3.5 ounce elastic, pull the first hook (3) onto the fourth hook (11) and pull the second hook (4) onto the third hook (10) for 8 to 20 hours. Replace the elastic when the tension decreases.
