Orthodontic molar C-shaped open band ring and manufacturing method thereof

Abstract

The invention relates to an orthodontic molar C-shaped open band ring and a manufacturing method thereof. The orthodontic molar C-shaped open band ring is an orthodontic molar anchorage device and consists of a cheek side face, a tongue side face, a distal surface, a section extending from a mesiobuccal axis angle position to a mesial surface, a section extending from a near tongue axis angle position to the mesial surface, a buccal tube and an overflow hole. The orthodontic molar C-shaped open band ring has a C-shaped band ring structure. The orthodontic molar C-shaped open band ring is combined with teeth by adhesive, and surrounds the dental crowns of the molars. The orthodontic molar C-shaped open band ring is available in big, middle and small sizes and can be fit with the shape of the crowns of the molars easily and can be regulated according to the micro shape differences between the teeth. When the orthodontic molar C-shaped open band ring is used, the complex and pain caused by tooth separation before orthodontic fixing can be avoided, the adhesion strength of the band ring and the crowns of the molars can be improved, the fixing is permanent, the loosening of the band ring is prevented, diagnosis times are reduced, the problem of tooth gap residue when the band ring is removed after the treatment is accomplished is solved, and blockage by food is avoided.

Description

technical field [0001] The invention relates to a novel orthodontic correction device-a C-shaped opening belt ring and a manufacturing method thereof. This kind of belt ring has high conformability to molars of different shapes, and its inner surface is coated with a layer of nano-scale hydroxyapatite, which can improve the bonding strength between the belt ring and the crown, and fully exert its anchorage effect. Background technique [0002] The development of fixed appliances has been nearly a hundred years, but no matter what kind of orthodontic system, the belt ring is a very important part. As far as the current orthodontic technology is concerned, malocclusion treatment cannot be completed without the participation of bands. [0003] Traditional orthodontic bands are pre-made into many different models and directly selected. Only when the clinician selects the belt ring that fits the molars from many models can it play a good role in retention. Orthodontic treatmen...

AI Technical Summary

Problems solved by technology

Therefore, the doctor's chair operation time and the patient's mouth opening time are greatly increased, and the chance of cross-infection is also increased.

[0006] 2. The teeth must be divided about 24 hours in advance before wearing the traditional belt ring, so it takes at least two days for the patient to fully wear all the fixed appliances, which causes great inconvenience to students and patients from other places

[0007] 3. Too many hard teeth and irritants will aggravate the damage of periodontal tissue

Patients generally report that the process of wearing the tooth separation device is painful

[0008] 4. The material of the traditional orthodontic belt ring is stainless steel sheet or metal alloy sheet. It has a certain thickness. When it goes down to the contact point, it will inevitably expand the gap between the adjacent teeth on both sides. It will be removed when the treatment is over. After wearing a ring, the adjacent two teeth tend to move obliquely to close the resulting gap, thus losing the normal adjoining point and creating a wedge-shaped gap, resulting in food impaction, which is the main cause of periodontal disease

Traditional belt rings cannot match the shape of the crown well, especially in the undercut area below the high point of the crown shape. Traditional belt rings cannot be closely attached to the crown

In addition, the traditional band is inserted vertically from the jaw of the teeth (the state of the upper and lower teeth occlusal), the inner surface of the band will generate friction with the high point of the crown, and the adhesive will flow from the Maxillofacial overflow, which will cause insufficient adhesive coating below the high point of the shape, providing a place for the accumulation of soft dirt and the reproduction of bacteria
