Description

Technical Field

[0001] This utility model relates to the field of orthodontic appliance technology, and in particular to a combined orthodontic appliance. Background Technology

[0002] Orthodontic appliances are dental devices used to adjust the position of teeth, improve bite, and enhance aesthetics. They move teeth by applying gentle, continuous force, helping to correct problems such as crowding, excessive gaps, and malocclusion.

[0003] Ectopic eruption of the first permanent molar is often caused by the mesial marginal ridge of the ectopic first permanent molar impacted below the distal cervical region of the second deciduous molar. This mainly results in adverse effects such as loss of eruption space for the second premolar, reduced dental arch length, and malocclusion. For irreversible mesial ectopic eruption of the first permanent molar, the modified Halterman appliance is widely used. It adopts a welded cast deciduous molar band, with a distal traction hook welded to the buccal side, and a lingual buckle bonded to the occlusal surface of the first permanent molar. A chain-like leather band is applied between the occlusal and lingual buckles to apply force, thereby applying distal traction to the first permanent molar. However, this approach has certain limitations and cannot apply appropriate force to the buccal-lingual ectopic first permanent molar.

[0004] In clinical practice, we have observed an increasing number of ectopic first permanent molars erupting buccally and lingually, resulting in malocclusion with localized locking. Traditional treatments for molar locking often involve brackets combined with orthodontic traction. This involves bonding lingual braces to the buccal and lingual sides of the rotated molars and then applying orthodontic elastics for traction. However, this method has limitations: 1. Braces can easily abrade the mucosa, resulting in poor comfort and low acceptance among young children; 2. The application time of the orthodontic traction elastics cannot be guaranteed, as children can remove them themselves, shortening the traction time. Therefore, there is an urgent need to develop a corresponding combination orthodontic appliance to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a combined orthodontic appliance to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular orthodontic appliance includes an appliance body and a chain-like brace. The appliance body includes a first metal band, a second metal band, a third metal band, and a lateral positioning component for connecting the first metal band, the second metal band, and the third metal band in series. The outer wall of the horizontal end of the third metal band has an integrated fastening component for tightening the end of the chain-like brace.

[0008] Preferably, the fastening assembly includes a fastening ring, the outer wall of which is fixedly connected to the outer walls of the three horizontal ends of the metal belt ring, the end of the chain-like rubber band is coiled around the outside of the fastening ring, and the outer wall of the end of the chain-like rubber band abuts against the three outer walls of the metal belt ring.

[0009] Preferably, the open end of the clamping ring is integrally formed with a side hook.

[0010] Preferably, the lateral positioning component includes two sets of side rings, and the first metal belt ring, the second metal belt ring, and the third metal belt ring are all fixedly connected to the two sets of side rings.

[0011] Preferably, the outer walls of the two sets of side rings abut against the horizontal ends of the chain-like leather rings on both sides.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this application, the metal bands are fixedly bonded to the teeth with adhesive. Metal band one is attached between the outermost deciduous tooth and the first permanent tooth. Metal band two and metal band three are attached between the first permanent tooth and the second permanent tooth, and on the other side of the second permanent tooth, respectively. The end of the chain-like elastic band is wrapped around the band and is fixed by cooperating with metal band three. The chain-like elastic band covers the outer side of the first permanent tooth, the second permanent tooth, and the deciduous tooth. Lateral positioning of the chain-like elastic band is achieved by two sets of lateral rings. At this time, the elasticity of the chain-like elastic band applies a buccal traction force to the first permanent molar, thereby achieving tooth correction. The orthodontic appliance is bonded by the doctor, and the child does not need to remove it at home, reducing the operation of the child and parents, increasing the convenience of treatment. Moreover, the appliance is smooth, the occlusal pad is raised and the bite is even, which increases the comfort compared to brackets and other similar appliances, and the child's acceptance is high.

[0023] A combined orthodontic appliance includes an appliance body and a chain-like braces 7. The appliance body includes a metal band 1, a metal band 2, a metal band 3, and a lateral positioning component for connecting the metal band 1, the metal band 2, and the metal band 3. The outer wall of the horizontal end of the metal band 3 is integrated with a tightening component for tightening the end of the chain-like braces 7.

[0024] Metal bands are fixed to the teeth with adhesive. Metal band 1 is attached between the outermost deciduous tooth and the first permanent tooth. Metal band 2 and metal band 3 are attached between the first permanent tooth and the second permanent tooth, and on the other side of the second permanent tooth, respectively. The end of the chain-like elastic band 7 is wrapped around the band 5 and is fixed by cooperating with metal band 3. The chain-like elastic band 7 covers the outer side of the first permanent tooth, the second permanent tooth, and the deciduous tooth. The chain-like elastic band 7 is laterally limited by two sets of lateral bands 4. At this time, the elasticity of the chain-like elastic band 7 applies a buccal traction force to the first permanent molar, thereby achieving tooth correction. The orthodontic appliance is bonded by the doctor, and the child does not need to remove it at home, reducing the operation for the child and parents, increasing the convenience of treatment. Moreover, the appliance is smooth, the occlusal pad is raised and the bite is even, which increases the comfort compared to brackets and other similar appliances, and the child accepts it more readily.

[0025] Specifically, such as Figure 2 and Figure 4As shown, the fastening assembly includes a buckle 5. The outer wall of the buckle 5 is fixedly connected to the outer wall of the horizontal end of the metal band 3. The end of the chain-like rubber band 7 is coiled around the outside of the buckle 5, and the outer wall of the end of the chain-like rubber band 7 abuts against the outer wall of the metal band 3. The end of the chain-like rubber band 7 is wrapped around the buckle 5, and the end of the chain-like rubber band 7 is fixed by cooperating with the metal band 3. The open end of the buckle 5 has an integrally formed side hook 6, and the end of the buckle 5 has an integrally formed side hook 6.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the lateral positioning assembly includes two sets of side rings 4. Metal belt ring 1, metal belt ring 2 and metal belt ring 3 are all fixedly connected to the two sets of side rings 4 to ensure the integrity of metal belt ring 1, metal belt ring 2 and metal belt ring 3. The outer walls of the two sets of side rings 4 respectively abut against the two sides of the horizontal end of the chain-like leather ring 7 to achieve the limiting of the two sides of the horizontal end of the chain-like leather ring 7.

[0027] Working principle: Metal bands are fixedly bonded to the teeth with adhesive. Metal band 1 is attached between the outermost deciduous tooth and the first permanent tooth. Metal bands 2 and 3 are attached between the first permanent tooth and the second permanent tooth, and on the other side of the second permanent tooth, respectively. The end of the chain-like rubber band 7 is wrapped around the loop 5, and the chain-like rubber band 7 is fixed by cooperating with the metal band 3. The chain-like rubber band 7 covers the outer side of the first permanent tooth, the second permanent tooth, and the deciduous tooth. Lateral restraint of the chain-like rubber band 7 is achieved by two sets of lateral rings 4. At this time, the elasticity of the chain-like rubber band 7 restrains the first permanent tooth, the second permanent tooth, and the deciduous tooth. A traction force is applied to the buccal side of the permanent molars to straighten the teeth. The orthodontic appliance is bonded by the doctor, so the child does not need to remove it at home, reducing the workload for the child and parents and increasing the convenience of treatment.
