Description

Technical Field

[0001] This utility model belongs to the field of orthodontic technology, and specifically relates to an auxiliary device for depressing elongated molars. Background Technology

[0002] Long-term molar loss leading to elongation of the opposing molar is common in adult patients, directly impacting tooth restoration. Currently, there are two main solutions. One is to grind down the elongated opposing tooth to create space for restoration; however, this method is not accepted by most patients due to the potential for tooth sensitivity or even pulp exposure. The other method involves using implant anchorage combined with a segmental arch to intrude and control the opposing tooth. However, this method is invasive, and some patients are unwilling to accept it due to the implant's inherent risk of failure.

[0003] Furthermore, the use of implant anchorage to depress elongated molars can be affected by many factors, such as the anatomical structure of the tooth root, the implantation site, the thickness of the patient's cortical bone, and the patient's oral hygiene. If the implant anchorage cannot pass through the resistance center of the depressed tooth, it may exert forces in other directions on the depressed tooth, resulting in tooth movement in other directions. When the mandibular cortex is thick, accidents such as fracture may occur during implant anchorage placement. For patients with poor oral hygiene, there is also a risk of recurrent redness and swelling of the peri-implant mucosa, purulent discharge, and even implant detachment.

[0004] Therefore, it is necessary to develop a non-invasive and comfortable molar depressor to solve the above problems. Utility Model Content

[0005] To address the above problems, this invention provides an auxiliary device for depressing elongated molars.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An auxiliary device for depressing elongated molars includes a retention body and a depressing elastic member. The retention body is disposed on a tooth in the same row as the elongated molar. Fixing members for fixing the depressing elastic member are provided on the inner and outer sides of the retention body. The fixing members are correspondingly disposed on both sides of the elongated molar. The depressing elastic member is used to depress the elongated molar.

[0007] Furthermore, the retention body is a transparent pressure film retainer, which is located on a row of teeth where the elongated molars are located. The top of the transparent pressure film retainer corresponding to the elongated molars is provided with a notch for the pressure-reducing elastic member to pass through. The fixing member is located on the inner and outer edges of the transparent pressure film retainer where the pressure-reduced tooth is located.

[0008] Furthermore, the inner and outer edges of the extended molar portion of the transparent pressure film retainer are provided with an extension portion for mounting a fastener, and the fastener is disposed on the outer side of the extension portion.

[0009] Furthermore, the width of the notch is 2-3 mm, and the bottom of the notch is 3-5 mm away from the gingival margin of the elongated molar.

[0010] Furthermore, the fastener is a single-wing tongue-side buckle or a double-wing tongue-side buckle, and the pressure-reducing elastic element can hook onto the single-wing tongue-side buckle or the double-wing tongue-side buckle on both the inner and outer sides of the transparent pressure film retainer.

[0011] Furthermore, the retention body is a cast orthodontic appliance, which includes a cast band, a palatal bar or a lingual arch. The cast band can be fixed to the teeth on the mesial side and the opposite side of the elongated molar. Fixing elements are welded to the lingual and buccal sides of the cast band on the mesial side of the elongated molar. The depressor can hook onto the fixing elements on the inner and outer sides of the elongated molar.

[0012] Furthermore, the fixing component is a traction hook, one end of which is connected to a cast belt ring, and the other end is provided with a hook for hooking and pressing down the elastic component.

[0013] The technological advancements achieved by this invention compared to existing technologies are as follows: This invention involves installing a retention body on the tooth in the same row as the elongated molar, and fixing components for securing the indentation elastic element on the inner and outer sides of the retention body. The indentation elastic element is then used to indent the elongated molar. This invention has a simple overall structure, is easy and convenient to use, is non-invasive in clinical operation, and provides high patient comfort. It is not limited by the anatomical structures of the tooth root or jawbone. Since the indentation force of the indentation elastic element can pass through the resistance center of the elongated molar, it can achieve overall indentation of the molar, avoiding unnecessary tilting or twisting, and achieving a better molar indentation effect. This provides a new orthodontic approach for clinical practice, while also being economical, comfortable, and aesthetically pleasing. Attached Figure Description

Detailed Implementation

[0016] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0017] This utility model provides an auxiliary device for depressing elongated molars, including a retention body and a depressing elastic element 2. The retention body is disposed on a tooth in the same row as the elongated molar 00. Fixing members for fixing the depressing elastic element 2 are provided on the inner and outer sides of the retention body, and the fixing members are correspondingly disposed on both sides of the elongated molar 00. The depressing elastic element 2 is used to depress the elongated molar 00. The depressing elastic element 2 is often an elastic ring. This solution, by installing a retention body on a tooth in the same row as the elongated molar 00 and fixing members for fixing the elastic ring on the inner and outer sides of the retention body, uses the elastic ring to depress the elongated molar. It is a non-invasive operation with a simple and compact structure, and high patient comfort. Specifically, there are two application embodiments: Example 1: As Figure 1 , 2 As shown, the retention body is a transparent pressure film retainer 11. The transparent pressure film retainer 11 is located on a row of teeth where the elongated molar 00 is located. The top of the transparent pressure film retainer 11 corresponding to the elongated molar 00 is provided with a notch 4 for the pressure-reducing elastic member 2 to pass through. The fixing member is located on the inner and outer edges of the transparent pressure film retainer 11 where the pressure-reduced tooth is located.

[0018] In the specific design, the inner and outer edges of the elongated molar of the transparent pressure-film retainer 11 are provided with extension portions 5 for installing fixation members, and the fixation members are located on the outer side of the extension portions 5. Meanwhile, the width of the notch 4 is 2-3 mm, and the bottom of the notch 4 is 3-5 mm from the gingival margin of the elongated molar 00. The fixation members are single-winged or double-winged lingual fasteners 3, and the depressurizing elastic member 2 can hook onto the single-winged or double-winged lingual fasteners 3 on both the inner and outer sides of the transparent pressure-film retainer 11. Figure 1 In the embodiment shown, the fastener uses a double-wing tongue-side buckle 3.

[0019] The fabrication and application process of the transparent pressure film retainer in this embodiment is as follows: 1. After the elongated molars are separated, an upper / lower jaw resin model or an upper / lower jaw impression is created using oral scanning and 3D printing technology and then filled with an ultra-hard plaster model. The resin / plaster is evenly trimmed to approximately 0.5 mm along the labial and lingual gingival margins of at least three teeth adjacent to the elongated molar to enhance the retention of the transparent indentation retainer. Plaster is filled below the highest point of the elongated molar to ensure that the elongated molar does not encounter resistance during indentation.

[0020] 2. Vacuum pressing is used to fabricate transparent press-fit retainers for the entire dentition of molars that need to be depressed. Except for the elongated molars, the labial and lingual margins of the retainer are about 2 mm long to enhance retention. The labial and lingual margins of the retainer at the elongated molars are about 6-7 mm long.

[0021] 3. Starting from the center of the labial crown of the elongated molar and ending at the center of the lingual crown, remove the transparent pressure retainer material with a width of about 2-3 mm from the labial, occlusal, and lingual sides of the elongated molar, leaving a notch for the pressure retainer required to depress the elongated molar.

[0022] 4. Mark a transparent indentation retainer about 5 mm from the gingival margin of the elongated molar on the extension line of the buccal and lingual crowns. Adhere a metal single-wing lingual retainer to each of these two marks. Place an indentation spring between the two single-wing lingual retainers to indent the molar.

[0023] Example 2: Figure 3 As shown, the retention body is a cast orthodontic appliance 12, which includes a cast band 6 and a palatal bar 7 connected to the cast band. The cast band 6 can be fitted onto the teeth on the mesial and contralateral sides of the elongated molar 00. Traction hooks 8 are welded to both the lingual and buccal sides of the cast band 6 on the mesial side of the elongated molar 00. The depressor 2 can hook onto the depressor 2 on the inner and outer sides of the elongated molar 00. The depressor 8 is made of stainless steel wire with a diameter of 1.0-1.2 mm; one end of the depressor 8 is connected to the cast band 6, and the other end has a hook for hooking onto the depressor 2.

[0024] The fabrication and application process of the cast orthodontic appliance in this embodiment is as follows: 1. After elongating the molars to complete tooth separation, use oral scanning and 3D printing technology to create resin models of the patient's upper / lower jaws, or create impressions of the patient's upper / lower jaws and pour ultra-hard plaster models; 2. Indentation of maxillary teeth: The maxillary molars on the indented side are connected to the molars on the opposite side by a cast band and palatal bar to form an integral support. A traction hook is welded to the lingual side and the buccal side of the molar to be indented on the cast band to hook the indentation elastic element and apply force. Indenting the mandibular teeth: The mandible is connected to the indented molar and the opposite molar by a cast band and lingual arch, which serves as an overall anchor. A traction hook is welded to the lingual and buccal sides of the indented molar on the cast band to hook the indentation elastic element and apply force. 3. The pressure spring is used to press down the elongated molar by passing over the buccal and lingual traction hooks.

[0025] In addition, by adjusting the position of the elastic ring and the traction hook, the direction of compression can be flexibly controlled, so that the compression force passes through the resistance center of the elongating molar as much as possible, and the overall compression of the elongating molar can be achieved, avoiding unnecessary tilting or twisting.

[0026] In summary, this utility model has the advantages of simple and compact structure, simple and non-invasive operation, and high patient comfort. It can avoid a series of problems caused by implant anchorage indentation, is not limited by the anatomical structure of tooth root, jawbone, etc., and the overall operation is non-invasive, safe and convenient. It provides a new orthodontic approach for patients who cannot accept invasive treatment. It has a good indentation effect while also being economical, comfortable and aesthetically pleasing.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
