Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an auxiliary adhesive guide plate for a lingual retainer. Background Technology
[0002] Lingual wire retainers, as an important auxiliary device in the later stages of orthodontic treatment, achieve invisible and stable retention by being fixed to the lingual side of the teeth, and have become an indispensable solution in modern orthodontic clinical practice. Their core advantage lies in their high degree of concealment and functional balance: the thin wires, made of stainless steel or nickel-titanium alloy, are fixed to the lingual side of the anterior teeth with resin adhesive, making them completely invisible and especially suitable for patients with high aesthetic requirements. Compared to traditional Halley retainers or clear film retainers, lingual wire retainers do not require patient removal, applying a gentle and stable force continuously to the teeth, effectively limiting tooth displacement. They are particularly suitable for children and adolescents with poor compliance or complex cases requiring long-term retention.
[0003] Lingual wire bonding presents several challenges, including limited field of vision and access: the narrow space on the lingual side of the teeth, coupled with significant interference from saliva and the tongue, severely impacts the operative field of vision and moisture isolation; difficulty in positioning: precisely stabilizing the lingual wire in the ideal position on the dental arch (usually above the lingual protuberance) by hand is extremely difficult, easily leading to lateral or anterior / posterior misalignment; and difficulty in controlling the adhesive: in the confined space, it is challenging to evenly apply the appropriate amount of resin to the bonding surface of each tooth and the lingual wire, often resulting in excessive resin overflow that irritates the gums, or insufficient resin leading to inadequate bonding strength. Therefore, medical professionals typically use a guide plate for assistance during bonding.
[0004] However, the existing guide plate has insufficient positioning accuracy and cannot effectively fix the tongue wire, causing it to rotate and shift before or during positioning. In addition, it lacks a resin injection channel, so the resin still needs to be applied manually in advance, which is complicated and inconvenient for the installation of the tongue wire. Utility Model Content
[0005] The purpose of this invention is to solve the problems that existing guide plates cannot effectively fix the tongue-side wires and are inconvenient for applying resin.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A lingual retainer auxiliary bonding guide plate includes a main body, a fitting part at the top of the main body, an engagement part between the fitting part and the bottom of the main body, a lingual wire positioning groove on the side of the main body facing the engagement part, a lingual wire being detachably engaged inside the lingual wire positioning groove, a plurality of injection holes on the side of the main body away from the engagement part, the other end of the injection holes communicating with the lingual wire positioning groove, and an overflow groove on the edge of the end of the injection hole connected to the lingual wire positioning groove.
[0008] Furthermore, the top of the assembly has an upper slot.
[0009] Furthermore, several through holes are provided between the bottom of the upper groove and the interlocking part.
[0010] Furthermore, the edges of the main body are provided with moisture-proof flanges.
[0011] Furthermore, the moisture-proof flange is made of a flexible material.
[0012] Furthermore, the main body is made of medical-grade resin material.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The present invention provides an auxiliary bonding guide plate for a lingual retainer, which, by setting a lingual wire positioning groove and an injection hole, can accurately position and install the lingual wire, and at the same time, can evenly inject resin into the connection between the lingual wire and the tooth, thereby achieving rapid bonding of the lingual wire.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4The tongue-side retainer 3D printing auxiliary bonding guide plate of this embodiment includes a main body 1. The top of the main body 1 is provided with a fitting part 9. A biting part 7 is provided between the fitting part 9 and the bottom of the main body 1. A tongue-side wire positioning groove 5 is provided on the side of the main body 1 facing the biting part 7. The tongue-side wire positioning groove 5 and the tongue-side wire are connected by an elastic buckle. A plurality of injection holes 2 are provided on the side of the main body 1 away from the biting part 7. The other end of the injection hole 2 is connected to the tongue-side wire positioning groove 5. An overflow groove 6 is provided on the edge of the end of the injection hole 2 connected to the tongue-side wire positioning groove 5. During bonding, the lingual wire is inserted into the lingual wire positioning groove 5 to position it. Then, the assembled guide plate is placed into the patient's mouth, so that the sleeve 9 fits over the top of the patient's teeth. At this point, the teeth are located inside the occlusal portion 7, ensuring the guide plate is fully in place. Next, the injection nozzle filled with flowing resin is inserted sequentially into the injection hole 2 corresponding to each tooth, and the resin is slowly injected. Under pressure, the resin evenly fills the gap between the tooth surface and the lingual wire from the gingival direction towards the incisal edge. The overflow groove 6 limits excess resin, preventing it from overflowing into the gingiva or proximal surfaces. After the resin injection is complete, the resin is initially light-cured from the labial side of the tooth. Then, the elastic clips between the guide plate and the lingual wire are released, and the guide plate is removed. The lingual wire has been evenly and firmly bonded to the patient's teeth to be corrected. Finally, a small amount of resin that has overflowed into the overflow groove 6 is removed, and final light curing is performed to achieve the bonding and installation of the lingual wire. Through the above steps, the lingual wire can be precisely positioned and installed, and the resin can be evenly injected into the connection between the lingual wire and the tooth to achieve rapid bonding of the lingual wire. Moreover, the structure is simple and easy to operate, simplifying the clinical operation steps, greatly shortening the intraoral operation time, and reducing the over-reliance on the doctor's operating skills. At the same time, it reduces the risk of dislodgement. Even if rebonding is required, a new guide plate can be quickly printed using the original data to ensure that the position remains unchanged, and to the greatest extent possible, prevent the patient's malformed teeth from being repositioned due to retainer failure.
[0022] The top of the assembly 9 has an upper slot 3; several through holes 4 are provided between the bottom of the upper slot 3 and the engagement part 7. By providing the upper slot 3 and through holes 4, the guide plate can be directly broken off along the upper slot 3 and through holes 4 after the retainer is glued, making it easy to remove the guide plate.
[0023] The edges of the main body 1 are provided with moisture-proof flanges 8; the moisture-proof flanges 8 are made of flexible material. By providing moisture-proof flanges 8, the soft tissue of the gingiva can be slightly pushed away at the edge of the guide plate, especially in the gingival margin area, after the guide plate is in place, to assist in moisture isolation.
[0024] The main body 1 is made of medical-grade resin material.
[0025] The guide plate body 1 can be manufactured in one piece using 3D printing technology. 3D printing can effectively improve the manufacturing precision of the guide plate, reduce manual operation errors, and ensure repeatability.
[0026] Working principle: During bonding, the lingual wire is inserted into the lingual wire positioning groove 5 to position it. Then, the assembled guide plate is placed into the patient's mouth, so that the sleeve 9 fits over the top of the patient's teeth. At this time, the teeth are located inside the occlusal part 7, ensuring that the guide plate is fully in place. Next, the injection nozzle filled with flowing resin is inserted into the injection hole 2 corresponding to each tooth in sequence, and the resin is slowly injected. Under pressure, the resin will evenly fill the gap between the tooth surface and the lingual wire from the gingival direction to the incisal edge. The overflow groove 6 can limit the excess resin to prevent resin from overflowing into the gingiva or proximal surface. After the resin injection is completed, the resin is initially light-cured from the labial side of the tooth. Then, the elastic clip between the guide plate and the lingual wire is released, and the guide plate is removed. The lingual wire is now evenly and firmly bonded to the patient's tooth to be corrected. Finally, a small amount of resin that has overflowed into the overflow groove 6 is removed, and final light curing is performed to achieve the bonding and installation of the lingual wire. Through these steps, the lingual wire can be precisely positioned and installed, and resin can be evenly injected into the connection between the lingual wire and the tooth, achieving rapid bonding. The structure is simple, the operation is convenient, simplifying clinical procedures, greatly shortening intraoral operation time, and reducing over-reliance on the doctor's operating skills. It also reduces the risk of dislodgement; even if rebonding is required, a new guide plate can be quickly printed using the original data to ensure the position remains unchanged, minimizing the risk of repositioning the patient's malformed teeth due to retainer failure.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
