Description

Technical Field

[0001] This utility model belongs to the field of oral medicine technology and relates to an improved anterior tooth occlusal elevation auxiliary tool. Background Technology

[0002] Temporomandibular joint disorder (TMJ) includes structural and functional disturbances of the condyle-articular disc-glenoid fossa, as well as masticatory muscle-related pain. Common clinical goals are pain relief, restoration of joint and muscle coordination, and reconstruction of a stable mandibular position. Many clinical protocols use "anterior occlusal elevation—relief of premature posterior contact—establishment of anterior guidance" as the starting point for treatment. This aims to bring the condyle closer to a central position within the glenoid fossa, reduce continuous traction on the lateral pterygoid muscles, and alleviate muscle tension, thereby providing a reliable mandibular space and reference jaw position for the fabrication of a stable or anterior guidance occlusal plate.

[0003] For patients with bruxism, raising the anterior fulcrum can reduce the intensity of masticatory muscle activity in the short term, reduce the contact area of ​​posterior teeth and the risk of wear, and help doctors quickly determine the appropriate occlusal vertical distance and lead amount before making a molded or removable occlusal splint.

[0004] Currently, the three main tools commonly used in clinical practice for anterior tooth occlusion elevation and deprogramming are as follows, each with its own limitations: 1. Leaf-shaped guide: This consists of multiple 0.1-0.2mm thick plastic or paper sheets stacked together. The vertical occlusal distance is adjusted by increasing or decreasing the number of sheets. It requires manual holding or temporary bonding during use, is prone to slippage, has poor positioning and reproducibility, and is prone to anterior-posterior displacement in patients with severe deep overbite. It is also uncomfortable to use for extended periods, and the sheets can adhere under saliva, resulting in unclear occlusal steps. 2. Warburg leaf-shaped guide: This is a bilaterally supported anterior tooth guide. It is large, obstructs the labial area, is difficult to adjust individually, and is uneconomical for single-use in clinical practice. 3. Lucia guide: A single-point guide is established by fixing the labial side of the upper anterior teeth and using a lingual guide. It is available in self-made and prefabricated types. The shape and elevation height of the self-made Lucia guide depend on the operator's clinical experience, and it is prone to loosening. The reproducibility of the guide angle and height is poor. The fit of the prefabricated Lucia guide is limited by the specifications. It requires chairside padding with self-curing resin or silicone rubber to increase retention. The lingual occlusal elevation part is difficult to meet the different needs of patients with deep overbite and normal overbite. In addition, the space for fine-tuning on site is limited, and the chairside operation time is long.

[0005] Therefore, there is an urgent clinical need to develop an anterior tooth occlusal elevation device that is simple in structure, stable in retention, can be quickly and individually adjusted, and is easy to use for single or repeated applications. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and propose an improved anterior tooth occlusal elevation assistive tool. This improved anterior tooth occlusal elevation assistive tool can quickly adapt to different overbite relationships and has a stable bilateral clamping structure and the ability for individualized adjustment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: This utility model discloses an improved anterior tooth occlusion elevation auxiliary tool, including an anterior lingual clamp, the anterior lingual clamp including a guide ramp and a base plate segment, the included angle between the guide ramp and the base plate segment is an obtuse angle; one end of the guide ramp is connected to the anterior labial clamp by a spring plate.

[0008] Furthermore, a detachable adjustable base is provided below the anterior lingual clamp, and the detachable adjustable base has a polyhedral structure.

[0009] Furthermore, the upper surface of the detachable adjustable base is provided with a plurality of positioning posts; the base plate segment is provided with a plurality of first through holes, and the positioning posts are fixed in the first through holes.

[0010] Furthermore, the detachable adjustable base is made of medical-grade thermoplastic material, and the softening temperature of the medical-grade thermoplastic material is between 60°C and 80°C.

[0011] Furthermore, the detachable adjustable base is available in various thicknesses.

[0012] Furthermore, both the anterior tooth labial clamp and the guide bevel are provided with several second through holes.

[0013] Furthermore, the angle range of the spring sheet is 20°~40°.

[0014] Furthermore, the inner surfaces of the anterior tooth labial clamp and the guide bevel are both provided with micro-protrusions or micro-tooth textures.

[0015] Furthermore, the labial clamp for anterior teeth and the lingual clamp for anterior teeth are made of medical-grade polymer material.

[0016] Furthermore, the spring sheet is made of elastic stainless steel with a thickness ranging from 0.3 to 0.8 mm.

[0017] Compared with the prior art, the present invention has the following beneficial effects: First, the labial and lingual clamps for anterior teeth achieve double-sided clamping, forming a "double-sided clamping + elastic rebound" structure with the spring plate, reducing the slippage and dislodgement of the device, and improving wearing comfort and bite step feel.

[0018] Second, the guide ramp and base plate of the anterior lingual clamp form a distal extension piece, which directly meets the anterior tooth occlusal elevation needs of patients with deep overbite; the detachable and adjustable base can quickly achieve individualized normal overbite and has dual-scenario adaptability.

[0019] Third, the detachable and adjustable base comes in various sizes to meet different height adjustment needs. At the same time, the detachable and adjustable base is made of medical-grade thermoplastic material, which softens and is shaped at 60℃~80℃. After softening in hot water, the patient can gently bite down to the target height. After solidification, the base can be removed to quickly achieve the target bite without the need for repeated clinical adjustments, thus shortening chairside operation time.

[0024] Exemplary embodiments will be described in detail below. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples consistent with some aspects of this invention as detailed in the appended claims.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Example

[0026] like Figure 1As shown, this utility model provides an improved anterior tooth occlusion elevation auxiliary tool, including an anterior lingual clamp 2. The anterior lingual clamp 2 includes a guide ramp and a base plate segment, and the included angle between the guide ramp and the base plate segment is an obtuse angle. One end of the guide ramp is connected to the anterior labial clamp 1 through a spring plate 3.

[0027] Specifically, this device is used to correct or treat patients with deep overbite. The guide ramp and the base plate segment form a distal extension, which in its default state forms a tilted guide plate to expand the occlusal contact range in the posterior tooth region of the oral cavity, assist in accurately positioning the occlusal relationship, stabilize the mandibular position, and prioritize meeting the anterior guidance needs of patients with deep overbite.

[0028] More specifically, the size of the obtuse angle is a factory-fixed value, ranging from 100° to 140°, preferably 120°.

[0029] Furthermore, such as Figure 2 , Figure 3 As shown, a detachable adjustable base 4 is provided below the anterior tooth lingual clamp 2, and the detachable adjustable base 4 has a polyhedral structure.

[0030] Specifically, the detachable adjustable base 4 is mounted on the base plate segment and can be used to correct or treat patients with normal anterior overbite. The specific operating steps are as follows: after softening the detachable adjustable base 4, it is placed on the lingual side, and the patient gently bites the guide plate to allow it to cool and solidify, thereby obtaining an individualized occlusal vertical distance and anterior guide angle.

[0031] Furthermore, the upper surface of the detachable adjustable base 4 is provided with a plurality of positioning posts; the base plate segment is provided with a plurality of first through holes, and the positioning posts are fixed in the first through holes.

[0032] Specifically, the number of positioning posts is equal to the number of the first through holes, and their positions correspond.

[0033] More specifically, the positioning post engages with the first through hole, facilitating the quick assembly of the anterior lingual clamp 2 with detachable and adjustable bases 4 of varying thicknesses.

[0034] Furthermore, both the anterior tooth labial clamp 1 and the guide bevel are provided with several second through holes.

[0035] Specifically, the second through hole facilitates the outflow of interlocking recording materials such as silicone rubber, and can also accommodate padding materials such as silicone rubber to increase retention force and prevent the device from falling off after the material hardens.

[0036] Furthermore, the angle range of the spring sheet 3 is 20°~40°.

[0037] Specifically, the preset angle of the spring plate 3 can ensure that the posterior teeth naturally separate when the chin is extended forward, avoiding premature contact of the posterior teeth, thereby protecting the temporomandibular joint, optimizing muscle function, avoiding dental trauma, and achieving deprogramming.

[0038] More specifically, the angle of the spring plate 3 is selected based on the natural angle of the human upper anterior teeth. The smaller the angle, the greater the force required to open it, and the greater the clamping force on the teeth; the larger the angle, the less likely it is to be clamped when the teeth are thin, or the clamping force may be too weak. Setting the angle range between 20° and 40° ensures stable positioning of the clamp and transmits occlusal guiding force through the contact point. Preferably, the angle is 30°.

[0039] Furthermore, both the inner surfaces of the anterior tooth labial clamp 1 and the guide slope are provided with micro-protrusions or micro-tooth textures.

[0040] Specifically, the micro-protrusions or micro-tooth textures can increase friction and enhance the retention ability of the modified anterior occlusal elevation aid.

[0041] Furthermore, the labial clamp 1 and the lingual clamp 2 for anterior teeth are made of medical-grade polymer material.

[0042] Specifically, the medical-grade polymer material may be medical-grade PC, medical-grade PMMA, or medical-grade transparent nylon (other medical-grade polymer materials may be used as needed).

[0043] Furthermore, the detachable adjustable base 4 is made of medical-grade thermoplastic material, and the softening temperature of the medical-grade thermoplastic material is between 60°C and 80°C.

[0044] Specifically, the medical-grade thermoplastic material is preferably PCL (other medical-grade thermoplastic materials can be used as needed), and the detachable adjustable base 4 made of PCL should avoid high-temperature steam sterilization and can be used only once.

[0045] More specifically, the softening temperature can prevent burns to patients during use while ensuring the thermoplastic material softens. The specific softening temperature can be determined according to the room temperature, and the preferred softening temperature is 60°C.

[0046] Furthermore, the spring sheet 3 is made of elastic stainless steel with a thickness ranging from 0.3 to 0.8 mm.

[0047] Specifically, elastic stainless steel can guarantee both elastic fatigue life and resistance to conventional disinfection methods (such as chemical cold disinfection and low-temperature plasma disinfection).

[0048] Furthermore, the detachable adjustable base 4 has various thicknesses.

[0049] Specifically, the thickness of the detachable adjustable base 4 is preferably 2mm, 4mm, 6mm, or 8mm.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, this embodiment also provides an operating method for a modified anterior tooth occlusion elevation auxiliary tool, as follows: I. When used for the treatment and correction of deep overbite in patients with anterior teeth, the steps are as follows: 1. For example Figure 4 As shown, after the modified anterior occlusal elevation assistive tool is opened, it is clamped at the patient's upper central incisors. If the anterior teeth of individual patients are more maloccluded, wax sheets, silicone rubber, alginate impression material, resin or even cotton balls and other common oral clinical consumables can be appropriately padded inside the clamp to increase the retention of the device. 2. Using the aforementioned guiding slope as the leading surface, guide the mandible to slide upward and forward to the position where the upper and lower anterior teeth lightly touch; 3. If the bite is raised too much, the thickness of the extension piece can be adjusted appropriately; if the bite is raised too little, a thermoplastic adjustment shim of similar height (such as 2mm or 4mm) can be inserted, and thermoplastic fine adjustment can be made if necessary. 4. Maintain this position for several minutes to deprogram the anterior teeth; 5. Use an intraoral optical scanner to scan the patient's bilateral posterior teeth area to directly obtain the digital occlusal relationship after occlusal elevation; alternatively, silicone rubber material can be directly applied to the bilateral posterior teeth for occlusal recording. Instruct the patient to bite normally, and remove the silicone rubber material after it has hardened to obtain a routine occlusal record after occlusal elevation.

[0051] II. When used for the treatment and correction of patients with normal anterior overbite, the steps are as follows: 1. For example Figure 5 As shown, the detachable adjustable base 4 with a height of 6mm is fixed below the anterior tooth lingual clamp 2. If the posterior tooth is raised too high at this time, the detachable adjustable base 4 is placed in 60℃ warm water to soften it to a plastic state. 2. Place the softened detachable adjustable base 4 under the anterior lingual clamp 2 again, and have the patient bite down gently to position it; 3. Fine-tune the relationship between the upper and lower jaws according to clinical goals (e.g., advance 2-3 mm, increase the vertical occlusal distance by 1.0-3.0 mm). During this process, the patient should continue to gently bite to position the jaw and wait for the material to cool and set. If necessary, it can be reheated for fine-tuning. 4. If the height of the existing detachable adjustable base 4 is too low, a thicker 8mm base can be selected, or bases of different thicknesses can be heated together and combined to make an individualized stable or leading type bite plate according to the shaped appearance.

[0052] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
