Problems solved by technology

[0003] In view of the above-mentioned prior art, in order to overcome the shortcomings of the existing orthodontic movable retainer base, such as heavy foreign body feeling, difficulty in cleaning, and inability to occlude the upper and lower teeth, the present invention provides a forged wire orthodontic retainer without base, which Not only does the retainer have no base, it is comfortable to wear, easy to clean, and will not adversely affect the temporomandibular joint and periodontal tissue. When worn, the upper and lower teeth can be naturally occluded, which is conducive to orthodontic maintenance

Embodiment 1

[0022] A forged wire orthodontic retainer without a base, including dental arch wires surrounding the buccal and lingual sides of No. 1 to No. 7 teeth, welding overbite steel wires between No. Weld over-occlusal steel wires between them, and weld over-occlusal steel wires between No. 3 and No. 4 teeth.

[0023] The dental arch wire is divided into an anterior segment and a posterior segment, and the posterior segment is further divided into a retention arm and an antagonism arm, and the specific distribution is as follows: the buccal side of tooth No. arm; both sides of No. 6 tooth are retention arms; the buccal side of No. 5 tooth is the antagonistic arm, and the lingual side is the retention arm; the buccal side of No. 4 tooth is the retention arm, and the lingual side is the antagonistic arm; 3, 2, 1 The dental arch wires on the labial side and lingual side of the number teeth are the anterior tooth segments, such as figure 1 shown.

[0024] The manufacturing method is as...

Embodiment 2

[0027] A forged wire orthodontic retainer without a base, including arch wires surrounding the buccal and lingual sides of No. 1 to No. 6 teeth, welding overbite steel wires between No. Over-occlusal steel wires are welded between them.

[0028] The dental arch wire is divided into the anterior segment and the posterior segment, and the posterior segment is further divided into a retention arm and an antagonism arm. The specific distribution is as follows: the buccal side of tooth No. arm; both sides of No. 5 tooth are retention arms; the buccal side of No. 4 tooth is the antagonistic arm, and the lingual side is the retention arm; the dental arch wires of No. 3, 2, and 1 teeth are all in the anterior tooth area on the labial side and lingual side part.

[0029] Manufacturing method is the same as embodiment 1.

Abstract

The invention discloses a base-free wrought wire orthodontic retainer which comprises a dental arch wire around the dental buccal and tongue sides of first to seventh teeth. An occlusion across steel wire is welded between the sixth tooth and the seventh tooth; an occlusion across steel wire is welded between the fifth tooth and the sixth tooth; an occlusion across steel wire is welded between the third tooth and the fourth tooth; and the dental arch wire is divided into a front dental section and a rear dental section. The rear dental section is divided into retention arms and allopathic arms which are specifically distributed in a manner that the buccal side of the seventh tooth is provided with the retention arms, and the tongue side of the seventh tooth is provided with the allopathic arm; both sides of the sixth tooth are provided with the retention arms; the buccal side of the fifth tooth is provided with the allopathic arm, and the tongue side of the fifth tooth is provided with the retention arm; the buccal side of the fourth tooth is provided with the retention arm, and the tongue side of the fourth tooth is provided with the allopathic arm; and dental arch wires of the lip and tongue sides of the first, second and third teeth are arranged in the front dental section. The base-free wrought wire orthodontic retainer is not provided with a base, is comfortable to wear and easy to clean, does not cause adverse effects on the temporomandibular joint and periodontium, and allows the upper and lower teeth to be naturally occluded when being worn, thus being favorable to clinical popularization and application.

Description

technical field [0001] The invention relates to a forging wire orthodontic retainer without a base. Background technique [0002] At present, the known orthodontic movable retainers mainly include Hastelloy retainers, annular retainers and transparent embossed retainers. However, the Hastelloy retainer and the ring retainer both have self-curing or thermosetting resin bases, which are difficult to clean and cause a heavy sensation of foreign body in the mouth when worn; while the upper and lower teeth cannot be occluded when the transparent laminated retainer is worn, which is harmful to the temporomandibular joint. Is a potential injury, and is not conducive to the health of periodontal tissue. It has been reported that there is no base retainer, and the continuous clasp or arrow clasp is used, and the molars are retained only. Because of the poor retention effect and high difficulty of production, it has not been widely used in clinical practice. Contents of the inventi...
