Description

Traction device for orthodontic treatment of embedded teeth

Technical Field

The utility model belongs to the field of medicine, and particularly relates to a traction device for orthodontic treatment of buried teeth.

Background

Buried teeth, also known as blocked teeth or blocked teeth, are commonly found on the maxillary cuspids and central incisors, followed by the mandibular second molars. The embedded teeth are one of reasons for causing the dislocation of the dentition disorder, the permanent teeth, and the like, and the incidence rate is 1-3%. At present, the embedded teeth mainly achieve the treatment purpose through surgical windowing and orthodontic traction. Common traction methods are divided into ligature wire traction, chain leather rings and nickel-titanium wire auxiliary arches. When the full-mouth orthodontic treatment is used for imbedding teeth, generally, after the orthodontic treatment is progressed to a certain stage and a hard arch wire is changed to basically maintain a tooth-missing gap and an adjacent tooth position, an operation is carried out on the anti-scaling teeth, after tooth surfaces are exposed, lingual side buckles are bonded at the labial cheek surfaces or the adjacent surfaces and the like, one end of a ligature wire is wound on the neck of the lingual side buckles, and the other end of the ligature wire is exposed to the oral cavity after mucous membrane suturing and is used for fixing a chain-shaped leather ring and is pulled to a main arch wire. The chain-like apron elasticity can decay over time, requiring monthly re-diagnosis changes. After the vital teeth are exposed to the oral cavity, the lingual tabs are typically replaced with conventional brackets and continued to be pulled into the correct position. This solution has a number of drawbacks: one end of the ligature wire is wound on the lingual buckle neck, so that the risk of falling off exists; and secondly, the chain-shaped leather collar is replaced every month, the ligature wire is required to be repeatedly loosened, and the ligature wire is easy to break. Both of these situations require re-surgical windowing to be performed on the obstructing teeth and lingual buckles, increasing patient pain.

In addition, there is an orthodontic solution for the embedded teeth in the prior art, that is, a lingual traction chain is used to replace the lingual buckle and the ligature wire, and the lingual traction chain comprises a chain and a bottom plate which are welded and fixed or integrally formed. After the operation is carried out on the anti-tooth and the tooth surface of the anti-tooth is exposed, a bottom plate of a lingual traction chain is adhered to the anti-tooth, and the chain end of the lingual traction chain is exposed after the mucous membrane is sutured; and connecting the lingual traction chain with the arch wire by using a rubber chain or a tension spring. Such lingual traction chains are more secure and there is little risk of requiring the patient to undergo multiple procedures. However, when the blocking tooth is pulled to expose the gum, the position of the blocking tooth which needs to be moved becomes short, and the lingual traction chain becomes inconvenient to apply force and is cumbersome and redundant, so that the bonded lingual traction chain needs to be removed at the moment and replaced by a common lingual buckle or a common bracket, and the tooth is pulled to a correct position continuously. In general, after the blocking tooth is exposed, the lingual traction chain stuck on the blocking tooth is removed and replaced by a common lingual buckle, so that the operation is tedious and time-consuming, the discomfort of a patient is increased, and the working efficiency of a doctor is reduced.

Accordingly, there is a need in the art for new techniques and apparatus to address the above-described problems.

Chinese patent CN202121400470.9 discloses a device for correcting the teeth of a wearer by blocking the teeth of a wearer, comprising a blocking hook adhered to the teeth of a wearer, a band adhered to the teeth of a wearer in the middle, a bracket adhered to the first and second bicuspids, and a band fixing device comprising a buccal tube welded to the buccal side of the band, and a multi-curved push spring welded to the distal and proximal surface of the band, wherein the multi-curved push spring is located at one side of the teeth of a wearer, the buccal tube is connected with the bracket via an arch wire, and the other end of the multi-curved push spring is a free end and is connected with the blocking hook in a matching manner. The utility model has the advantages of convenient installation, short re-diagnosis time, high curative effect, comfort, beautiful appearance and wide application range. However, the appliance described in this patent is only suitable for use in the inhibition of molar teeth and does not provide any effect on buried teeth which may be found elsewhere in the mouth.

Chinese patent CN202221199351.6 discloses a traction component and a traction tongue side buckle for bone-embedded tooth-blocking/grinding, the traction tongue side buckle includes an adhesive buckle, a chain-shaped part connected with the adhesive buckle, and a connecting part connected with the chain-shaped part, one end of the connecting part is connected with the chain-shaped part, the other end is provided with a free end, and the free end is a question mark hook. The traction assembly and the traction tongue side buckle are used as auxiliary devices for orthodontic treatment, so that doctors can more efficiently and conveniently carry out clinical operation, and patients can conveniently carry out self-operation to carry out stress application traction on the vital teeth. The traction lingual buckle of the utility model has the same or similar function as the lingual traction chain in the prior art, and the patent still cannot solve the defect that the lingual traction chain or the chain for traction lingual buckle is too cumbersome in the oral cavity after the embedded tooth is pulled out of the tooth gingiva, and needs to be replaced and stuck into the common lingual buckle.

Chinese patent CN202021851893.8 discloses a novel chain tongue side knot, including the chain and with the base of tooth bonding, one side that the tooth was kept away from to the base is equipped with the connecting rod, and the one end that keeps away from the base of connecting rod is connected with the metal ball, and the metal ball is connected with the chain, all be equipped with the towing hook on every chain link of chain. Compared with the chain type lingual buckles in the prior art, the chain type lingual buckle traction force is simple to apply, and the common lingual buckle does not need to be replaced in the later period. However, the chain lingual buckle is still redundant when it is present in the oral cavity at a later stage.

Chinese patent CN202222485283.6 provides a wire-threaded lingual side buckle for orthodontic use and a lingual inclination incisor root control mobile appliance. The threading tongue side buckle comprises a base and an arc-shaped or round or hemispherical protruding part positioned on the base, and a threading hole is formed in the protruding part. The appliance comprises a threading lingual buckle arranged on the lingual side of the central incisors of the upper jaw and a flat guide anchorage device arranged on the lingual side of the upper jaw, wherein the flat guide anchorage device comprises a palate support, a connecting arch wire, a first molar belt ring, a second molar belt ring and a binding wire fixing rod, the first molar belt ring and the second molar belt ring are connected through the connecting arch wire, the palate support is positioned at the front palate part of the connecting arch wire, and two ends of the binding wire fixing rod are fixed in the palate support; the ligature wire passes through the wire penetrating hole of the wire penetrating tongue side buckle and then ligates with the ligature wire fixing rod. The lingual side buckle can be used for threading and ligating fixed teeth, and the appliance has the advantages that the root control movement of the lingual middle incisors is realized, the normal axial inclination of the dislocated teeth is recovered faster, and the occurrence rate of bone windowing is avoided. Chinese patent CN202221610324.3 provides an i-shaped tongue side fastener with a groove, which comprises a base, a torsion column and a supporting head connected in sequence, wherein the torsion column is vertically arranged on one surface of the base, and the supporting head is positioned at one end of the torsion column far away from the base; the torsion column is provided with an archwire hole in a penetrating way. The I-shaped tongue side buckle with the groove is characterized in that two ends of the tongue side buckle are respectively a collet adhered to teeth and a supporting head close to the inner wall of an oral cavity, a torsion column with an archwire hole is arranged on the surface of the collet, and a bent stainless steel wire penetrates through the archwire hole according to the target orthodontic effect during use so as to control torque after the embedded teeth are pulled out. Both of these patents relate to a new threading tongue-side fastener having a threading hole provided in the tongue-side fastener for threading an elastic wire. The scheme is used for correcting the teeth after the teeth are prevented from being exposed out of the gingiva; compared with the method that ligature wires are wound around the neck of a common lingual buckle, the scheme is not easy to take off wires. However, this solution presents a greater resistance when placing the archwire in the wire-passing hole, and is more difficult and more inconvenient to operate clinically, especially if one wants to pass a longer length of archwire through the wire-passing hole.

Thus, there is a need in the art for a new traction device for orthodontic treatment.
