Abstract
Description
Technical Field
[0001] The utility model relates to oral treatment, and particularly to a device for assisting in the intraoral positioning and bonding of periodontal splints or lingual retainers. Background Art
[0002] 1. Periodontal Splint
[0003] Periodontitis is an inflammatory disease that affects the structures around teeth. The main symptoms include swollen and bleeding gums, tooth mobility, etc. Tooth mobility is a common symptom in the late stage of periodontitis, seriously affecting the chewing function and quality of life of patients. Periodontal fiber splints are a commonly used treatment method. By connecting loose teeth to healthy teeth, a stable chewing group is formed to help disperse the biting force and reduce the burden on the affected teeth.
[0004] However, since most of the existing periodontal fiber splint fixation techniques are completed through operations in the patient's mouth, there are indeed some limitations, mainly including:
[0005] (1) High technical requirements for operators: It requires operators to have high clinical skills and good cooperation from patients, which increases the complexity and difficulty of treatment.
[0006] (2) Long operation time: The average treatment time may take 0.5 to 1 hour, which not only increases the discomfort of patients but also affects the utilization efficiency of medical resources.
[0007] (3) Difficult positioning and fixation: The lingual retainer needs to be accurately positioned and fixed on the lingual side of the teeth, especially in crowded or irregular tooth arrangements.
[0008] (4) General degree of fit between the splint and the teeth: Especially in crowded or irregular tooth arrangements, it may be difficult for the fiber splint to achieve complete fit, affecting its fixation effect and ability to disperse the occlusal force.
[0009] (5) Difficult shape control: It is difficult to accurately control the size, shape, and edge treatment of the splint, which may affect the anti-fracture, anti-detachment ability, and aesthetic effect of the splint.
[0010] (6) Difficult oral self-cleaning: It is difficult for the splint to achieve a high degree of polishing in the oral cavity, and it is easy to adhere to plaque, increasing the risk of dental calculus deposition and dental caries.
[0011] (7) Easy to stain and difficult to clean: The fiber splint is easy to stain, and it is particularly difficult to clean the edges, which may affect the aesthetics of patients.
[0012] 2. Lingual Retainer
[0013] Orthodontic treatment is a treatment method that improves occlusion and facial aesthetics through tooth movement. After the treatment is completed, the teeth and jaws do have a tendency to return to their original positions, which is called relapse. Therefore, mechanical retention of the teeth after orthodontic treatment using a retainer is very important. It can help the periodontal tissue to reconstruct, enabling the teeth, jaws, and soft tissues to reach a new balance, thus maintaining the effect of orthodontic treatment. Among them, lingual retainers (some of which have a form similar to a periodontal splint) play an important role in orthodontic retention. They can be pre-formed outside the body and then bonded to the lingual sides of the upper and lower anterior teeth. However, they also have some limitations:
[0014] (1) Difficulty in positioning and fixation: The lingual retainer needs to be accurately positioned and fixed on the lingual side of the teeth, which is technically challenging.
[0015] (2) Operational complexity: The bonding process of the lingual retainer is carried out in the oral cavity, which increases the operational complexity. The bonding process is not only time-consuming but also requires the patient's high cooperation to ensure the bonding effect.
[0016] (3) Uncertainty of bonding effect: The bonding process may be affected by the oral environment (such as humidity, saliva, etc.), which may reduce the success rate of bonding and the stability of the retainer.
[0017] (4) Lack of auxiliary tools: Currently, there may be a lack of effective auxiliary tools to simplify the bonding process and improve operational efficiency. This may lead to low efficiency for the operator during bonding, increasing the treatment time and cost. Summary of the Utility Model

However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, some well-known technical features are not described to avoid confusion with the present utility model.
[0037] To thoroughly understand the present utility model, detailed steps and structures will be presented in the following description to explain the technical solution of the present utility model. The preferred embodiments of the present utility model are described in detail below. However, in addition to these detailed descriptions, the present utility model can also have other implementation manners.
[0038] Referring to Figure 1 As shown, the present utility model provides a device for assisting in the intraoral positioning and bonding of a periodontal splint or lingual retainer. The structures of the periodontal splint and the lingual retainer are basically the same, except for their different functions. The structure and usage method of the present utility model for the periodontal splint or the lingual retainer are the same. The following takes the auxiliary positioning of the periodontal splint as an example for illustration.
[0039] The periodontal splint 1 is positioned and bonded to the lingual side of the tooth through the device of the present utility model. The device is composed of an intraoral positioning mechanism 2 fixedly connected to the periodontal splint 1 and a handle 3 detachably connected to the intraoral positioning mechanism 2. After the periodontal splint 1 is positioned and bonded to the lingual side of the tooth by using the device, the intraoral positioning mechanism 2 is separated from the periodontal splint 1 by cutting. The structures of the intraoral positioning mechanism 2 and the handle 3 are further described below.
[0040] Intraoral positioning mechanism 2
[0041] As Figure 2As shown in the figure, the intraoral positioning mechanism 2 includes a buckle 21 and a retaining rod 22. At least one "J"-shaped buckle 21 is provided on both sides of the periodontal splint 1. One end of the buckle 21 is fixedly connected to the lingual side of the periodontal splint 1, and the other end is clamped on the tooth.
[0042] The retaining rod 22 is a "T"-shaped rod composed of a cross bar 221 and a longitudinal bar 222. Both ends of the cross bar 221 are fixedly connected to the lingual sides of both sides of the periodontal splint 1. One end of the longitudinal bar 222 is fixedly connected to the cross bar 221, and the other end is fixedly connected to the lingual side of the incisors of the periodontal splint 1. A rectangular jack 23 is provided at the connection of the cross bar 221 and the longitudinal bar 222.
[0043] In an alternative embodiment, the intraoral positioning mechanism 2 and the periodontal splint 1 are integrally designed in digital software, and then the periodontal splint 1 with the intraoral positioning mechanism 2 is integrally formed by 3D printing technology.
[0044] In another embodiment, the intraoral positioning mechanism 2 and the periodontal splint 1 can also be prepared separately, and then the intraoral positioning mechanism 2 is fixed to the lingual side of the periodontal splint 1 by an adhesive method.
[0045] Handle 3
[0046] As Figure 3 shown in the figure, one end of the handle 3 is provided with a plug rod 31 inserted into the jack 23. The cross section of the plug rod 31 is rectangular, so that the plug rod 31 cannot rotate after being inserted into the jack 23, so as to connect the handle 3 with the intraoral positioning mechanism 2. The other end of the handle 3 bends and extends outside the mouth, which is convenient for the doctor to hold the handle in the mouth and position the periodontal splint 1.
[0047] In an alternative embodiment, the other end of the handle 3 is provided with a lanyard hole 32. During the intraoral operation, in order to prevent surgical instruments from falling into the patient's mouth, the doctor can put a thin string on the hand, and the other end of the thin string is connected to the handle 3 through the lanyard hole 32, so that even if the handle 3 accidentally falls off, it will not fall into the patient's mouth.
[0048] The specific application steps of the present utility model are as follows:
[0049] (1) The clinician obtains the patient's intraoral data through intraoral scanning.
[0050] (2) According to the patient's dentition data, the dental technician performs personalized design on the shape of the periodontal splint 1 (including length, width, thickness, and marginal transition, etc.) through design software, and fits the intraoral positioning mechanism 2 with the periodontal splint 1 in the software.
[0051] (3) Process the periodontal splint by digital / traditional processes, including but not limited to 3D printing, cutting, or injection molding, etc., to form the Figure 2 structure shown in the figure.
[0052] (4) After applying self-etching adhesive to the lingual side and interdental spaces of the teeth corresponding to the periodontal splint, dry the tooth surface and cure it by light.
[0053] (5) Insert the handle 3 into the jack 23 of the intraoral positioning mechanism 2, and then wear the periodontal splint 1 on the lingual side in the patient's mouth. The doctor can conveniently adjust the wearing position of the intraoral periodontal splint 1 outside the mouth through the handle. After positioning, cure it by light to complete the bonding of the periodontal splint 1 on the lingual side. During this process, the doctor pinching the handle can avoid unnecessary displacement of the periodontal splint 1 in the mouth and improve the positioning accuracy of bonding.
[0054] (6) After the bonding is completed, the clinician pulls out the handle 3, and then cuts and polishes the roots of the buckle 21 and the retention rod 22 to separate the buckle 21 and the retention rod 22 from the periodontal splint 1. Only the periodontal splint 1 is retained in the mouth, and the cut ends of the buckle 21 and the retention rod 22 are appropriately polished to ensure patient comfort and facilitate self-cleaning of the splint.
[0055] The advantages of the present utility model are as follows:
[0056] 1. It improves the positioning accuracy and bonding effect of the periodontal splint or lingual retainer. By using the device of the present utility model, the doctor can easily adjust the position of the periodontal splint or lingual retainer outside the mouth through the handle, ensuring its accurate fitting on the lingual side of the teeth, improving the positioning accuracy and fixing stability of the lingual retainer or loose tooth splint, and thus being beneficial to improving the treatment effect.
[0057] 2. It simplifies the operation process and reduces the surgical difficulty. In the traditional method, the doctor needs to directly operate in the mouth, with limited vision and inconvenient operation. The present utility model, through the combined use of the intraoral positioning mechanism and the handle, enables the doctor to perform positioning operations outside the mouth, greatly simplifying the surgical process and reducing the doctor's operation difficulty and time.
[0058] 3. It enhances the patient's treatment experience and reduces compliance problems caused by discomfort.
[0059] 4. It enhances the durability of the periodontal splint or lingual retainer and extends its service life.
