Description

Vertical auxiliary spring for mandibular impacted molar

Technical Field

The invention relates to the technical field of tooth orthodontics, in particular to a lower jaw impacted molar vertical auxiliary spring.

Background

Molar occlusions are a serious dentognathic deformity with an incidence of 0.65-1.36% in the population. Although the incidence rate is not high, the molar occlusion hinders the normal occlusion of the teeth, affects the chewing function of the oromandibular system, and due to the low occlusal plane, it is easy to extend the jaw teeth, forming occlusal interference and false periodontal pockets, causing plaque to adhere, increasing the possibility of caries and periodontitis, and damaging the first molar distal root. From clinical investigations, it can be seen that the impacted second molar is manifested as a anteverted horizontal impacted, i.e. the second molar crown bears against the distal or medial root of the first molar crown. This is also a manifestation of crowding of the posterior arch. The X-ray panoramic picture of the oral cavity shows that the anteverted impacted molar crown is positioned at the far middle neck part (anchorage tooth) of the mesial molar, part of the affected dental caries caused by food impaction is usually treated by the technologies of surgical extraction, anchorage traction to a jaw implant, fixed correction and appliance combined with a molar belt girth welding multi-curve push spring, retromolar retroflexion and the like, but the method exposes the impacted buccal surface of the molar to bring surgical trauma, is not easy to accept by patients, has more complex operation, is difficult to finish by most doctors, and has the risk of desoldering and foreign matter falling into the throat in the welding technology.

Disclosure of Invention

In order to solve the problems, the invention provides a lower jaw impacted molar vertical auxiliary spring which mainly can realize the following experimental targets:

the far end of the vertical auxiliary spring is hung on the stable main arch wire, an L-shaped curve with a ring is bent, the elasticity of the auxiliary spring is increased, light-force vertical bruising is realized, the auxiliary spring with the ring is adjusted in times to apply force gradually, and the forward-leaning bruising is vertical.

In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:

the utility model provides a lower jaw hinders upright supplementary spring of giving birth to molar, cooperation tooth are fixed to be rescued the ware and act on the tooth surface, include and hinder the upright supplementary spring of L type area circle of giving birth to molar side looks adaptation, upright the nearly heart end of assisting the spring and buckling into the elastic ring, upright the far heart end of assisting the spring and buckling into the couple and hang on main arch wire.

Furthermore, the elastic ring, the hook and the elastic steel wire between the two vertical auxiliary springs are formed by integrally bending a stainless steel wire.

Further, the vertical auxiliary spring is made by bending 0.018 × 0.025 inches or 0.017 × 0.022 inches or 0.016 × 0.022 inches of stainless steel square wires.

The invention has the beneficial effects that:

1. the auxiliary spring is separately bent and separately functions with the main arch wire, and the moving requirements of other teeth are not influenced. The main arch wire and the filament are not needed to be replaced for accommodating the inclined teeth into the correction, so that the movement of other teeth is influenced, and the treatment course is prolonged.

2. The size of the auxiliary spring can be flexibly adjusted according to the dentition clearance, the inclination degree, the vestibular groove depth, the soft tissue position and the like.

3. The elastic ring on the auxiliary spring increases the elasticity and the correcting force is softer due to the increase of the length of the arch wire.

4. The auxiliary spring is formed by bending a square wire, and is more favorable for controlling the buccal-lingual torque of the teeth.

5. The correcting device for treating the anteverted impacted molar is simple to manufacture, does not need to influence the appearance and daily life, is not limited by time when in use, can be selected to correct the anteverted impacted molar in all weather, has maximized potential, is fixed in the mouth, has small foreign body sensation, is easy to clean and sanitary, does not depend on the cooperation of patients in curative effect, does not have surgical complications, and is willing to be accepted by the patients.

6. The existing impacted molar treatment technology mainly treats bone tissue invasively or extracts, has the defects of higher operation difficulty of deeply buried horizontal impacted molar, and increases the chances of infection and trauma because bones are removed by matching with an operation to expose the buccal surface of the impacted molar. The auxiliary arch for correcting the impacted molar thoroughly avoids the defects under the condition of ensuring the curative effect.

7. In the aspect of environmental protection: the existing correction device has the disadvantages of complex manufacturing process, various materials, non-recoverability and waste after individualized use. The auxiliary arch for correcting the impacted molar can be recycled and reused after disinfection, thereby greatly saving materials, reducing energy consumption and having no environmental pollution.
