Abstract

The utility model relates to an orthodontic device for changing the position of grinding teeth, which comprises an arch thread, both ends of which are provided with ring belts. Circlet curves with diameters between 3 to 5mm are respectively bent on the positions corresponding to positions of the arch wire and between a first pair of canines and a second pair of canines as well as between the second pair of canines and molars. The utility model increases the length of the arch wire with an increased force, improves the elasticity of the arch wire, and the stress of the molars is softer. The mesial part and the distal part of the circlet curve can be adjusted along the vertical direction, so deformities of the molars along the vertical direction can be effectively cured. The effect of a tongue body in the mouth on the circlet is passed on to the molars, which helps the treatment of the deformities of the molars. The circlet curve can be used as traction with other teeth to provide steady anchorage.

Description

A kind of just abnormal device that changes molar locations

Technical field

This utility model belongs to the orthodontics medical instruments field, particularly relates to a kind of just abnormal device that changes molar locations.

Background technology

Wrong jaw abnormality, claim again " dentofacial anomaly ", be meant the people in growth and development process, by inborn inherited genetic factors or posteriori environmental factors, as disease, oral habit is for the unusual tooth that causes, the jawbone of waiting of tooth, the deformity of cranium face, uneven as tooth arrangement, the jaw relation between upperdental arch is unusual, jawbone size and form malposition etc.For because the deformity teeth, particularly tooth amount of tooth amount bone amount due to uncomfortable, adopts the method that enlarges dental arch greater than the situation of bone amount is just abnormal subject treatment means commonly used.The lower jaw denture is owing to its anatomical features, and the existence of tongue, and the densification of mandibular bone cortex are used hyoid arch always as the device that expands bow.In addition the effect of hyoid arch also has: keep and an adjustment width of grinding one's teeth in sleep, keep the length of upperdental arch, correct to reverse and grind one's teeth in sleep, the control root of grinding one's teeth in sleep moves, and increases anchorage or the like.Therefore hyoid arch is widely used as clinical just abnormal adnexa commonly used.At present, the dental arch of clinical use expands the bow device because the afterburning arch wire of structure is made of a level and smooth steel wire, lacks and effectively extends and elasticity, cause the correcting action of backteeth not good, unsatisfactory curative effect; The bicuspid district contacts with afterburning arch wire, and the clinical bicuspid of rescuing when grinding one's teeth in sleep deformity usually takes place by undesirable moving, and side effect is big; It is excessive to rescue power.Grind one's teeth in sleep loosening and root absorption usually take place; Can't rescue the deformity of grinding one's teeth in sleep in vertical direction.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of just abnormal device that changes molar locations is provided, can persistently apply the soft power of rescuing to grinding one's teeth in sleep, making grinds one's teeth in sleep, and effectively just abnormal moving taken place, thereby corrects the wrong jaw abnormality of grinding one's teeth in sleep fast.

In order to reach the realization above-mentioned purpose, the technical solution adopted in the utility model is: a kind of just abnormal device that changes molar locations, include arch wire 1, arch wire 1 two ends are provided with band 3, and first bicuspid 4 and second bicuspid 5 between and the position of second bicuspid 5 and the corresponding arch wire 1 between 6 of grinding one's teeth in sleep, bend diameter respectively and be 3～5 millimeters helical loop 2.The quantity of said helical loop 2 is more than 1.Said helical loop 2 can be carried additionally the India rubber circle.

Because arch wire 1 is provided with helical loop 2, has increased the length of afterburning arch wire 1, has improved the elasticity of arch wire 1; Helical loop 2 and bicuspid distinguish from, do not influence bicuspidal treatment when afterburning; Because the elastic increase of arch wire, it is stressed softer to grind one's teeth in sleep, and has protected and has moved the physiological health of grinding one's teeth in sleep; Can adjust in vertical direction during the nearly neutralization of helical loop 2 is far away, effectively treat the deformity of grinding one's teeth in sleep in vertical direction; The oral cavity internal tongue is delivered to the effect of ringlet and grinds one's teeth in sleep, and odd-shaped rescuing helps to grind one's teeth in sleep; Helical loop 2 can draw with other teeth, and firm anchorage is provided.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is user mode figure of the present utility model.

The specific embodiment

Describe structural principle of the present utility model and operation principle in detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, this utility model includes arch wire 1, arch wire 1 two ends are provided with band 3, and first bicuspid 4 and second bicuspid 5 between and the position of second bicuspid 5 and the corresponding arch wire 1 between 6 of grinding one's teeth in sleep, bend diameter respectively and be 3～5 millimeters helical loop 2, in helical loop 2 far away in the cheek side, near in the tongue side.

During use, this utility model band 3 is enclosed within grinds one's teeth in sleep on 6, arch wire 1 is placed on the dental arch inboard, and this device is put into after the mouth, and the motion that the patient can be by tongue is used arch wire 1, helical loop 2 with masterpiece and assisted that backteeth is odd-shaped to be rescued.Enlarge arch wire 1 to both sides, removable grinding one's teeth in sleep laterally, thus enlarge backteeth section dental arch, the wrong jaw abnormality of treatment backteeth tongue side; Dwindle arch wire 1 to the inside, removable grinding one's teeth in sleep to the inside, thus dwindle backteeth section dental arch, the wrong jaw abnormality of treatment backteeth cheek side; Adjust in helical loop 2 near and the height in far away, can produce grinding one's teeth in sleep vertically to effect, set upright in can be far and grind one's teeth in sleep; Helical loop 2 can be carried additionally the India rubber circle, assists rescuing of multiple wrong jaw abnormality.

Claims

1. just abnormal device that changes molar locations, include arch wire [1], arch wire [1] two ends are provided with band [3], it is characterized in that, and first bicuspid [4] and second bicuspid [5] between and to bend diameter respectively be 3～5 millimeters helical loop [2] second bicuspid [5] and the position of corresponding arch wire [1] between [6] of grinding one's teeth in sleep.

2. according to the just abnormal device of the said change molar locations of claim 1, it is characterized in that the quantity of said helical loop [2] is more than 1.
