Description

Technical Field

[0001] The utility model relates to the technical field of oral orthodontic instruments, and in particular to an improved 3D printed transverse palatal rod for oral orthodontics. Background Art

[0002] According to the law of action and reaction, during orthodontic treatment, when the correction force is generated, an equal and opposite reaction force will inevitably be generated. Orthodontists often need to find ways to counteract the reaction force caused by the correction force, and the situation of supporting the reaction force caused by the movement of the correction tooth is called "anchorage". The common strategy of anchorage control is to concentrate the action force on the area where the tooth is expected to move, and to disperse the reaction force as much as possible on other teeth, palate, head and neck, or implants in the jaw, to ensure that the pressure on the periodontal membrane of the anchoring tooth is as small as possible.

[0003] Medical workers have found that the transverse palatal bar is a commonly used device for increasing support in orthodontic clinics. It is connected to the first molars on both sides of the maxillary teeth and spans the upper palate. It increases molar support by releasing part of the reaction force when moving the teeth to the palate. However, the fixed half rings at both ends of the transverse palatal bar cannot be adjusted to fit different molars. Users need to replace them to correct different molars, which is time-consuming, labor-intensive and cost-intensive. Therefore, we propose an improved 3D printed transverse palatal bar for orthodontics. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the transverse palatal bar is a commonly used device for increasing support in orthodontic clinics, which is connected to the first molars on both sides of the maxillary teeth and spans the upper palate.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. When the utility model is used, first use 3D printing to print out a transverse palatal rod body that matches the user, then install the fixing column installed on the protrusion in the fixing hole opened in the middle of the fixing plate, and then use the fixing bolt to fix the movable block on the protrusion, so as to fix the fixing half ring connected to the fixing plate and the connecting block, and then install the implant nail through the installation hole opened in the middle of the transverse palatal rod body, and at the same time install the fixing half ring and the user's molars.

[0024] In the present embodiment, preferably, the angle between the top projections of the palatal bars of the transverse palatal bar main body 1 is greater than 120 degrees; making the angle between the top projections of the palatal bars of the transverse palatal bar main body 1 greater than 120 degrees can provide greater tension, while allowing the transverse palatal bar main body 1 to fit more closely with the user's upper palate, thereby improving the orthodontic effect.
