Description

Technical Field

[0001] This utility model relates to the field of occlusal pads, and more particularly to an occlusal pad with adjustable vertical distance and occlusal pressure monitoring function. Background Technology

[0002] Jaw position refers to the three-dimensional spatial relationship of the mandible relative to the maxilla and craniofacial complex, serving as the fundamental reference frame for oral functions (such as chewing and speech). Deprogramming is a clinical technique aimed at eliminating pathological neuromuscular memories (neuromuscular reflex habits) formed in patients due to long-term abnormal occlusion (such as occlusal interference or premature contact), and by guiding the mandible to a physiologically relaxed position, thereby reconstructing a coordinated neuromuscular control pattern and physiological jaw position relationship. The core objectives of this process include: relieving abnormal occlusal locks, promoting the restoration of the temporomandibular joint condyle to a stable anterosuperior position within the glenoid fossa, and reshaping the physiological neuromuscular reflex arc.

[0003] The main treatment methods currently include: Anterior tooth guide plate method: After taking an impression or scanning, a resin planar guide plate (flat guide) covering the anterior tooth area (or anterior teeth plus part of the posterior teeth) is fabricated on the model to guide the patient to perform small opening and closing movements. The guide ramp design helps posterior teeth disengage from occlusal contact, thereby isolating posterior occlusal interferences and attempting to record the mandibular position in an "interference-free" state (usually referring to the muscle contact position, MCP). Technical limitations: While the device is simple in design, it can only eliminate interference in the anterior region and cannot effectively isolate occlusal locks in lateral or distal retraction positions. Furthermore, due to the angle design of the guide ramp, patients are prone to mandibular deviation or compensatory contraction or spasm of the masticatory muscles (temporalis and masseter), leading to unstable recording results.

[0004] The cotton roll biting method: This method uses soft cotton rolls or bite pads to mechanically separate the upper and lower posterior teeth (placed in the bilateral molar areas). The patient is instructed to gently bite or perform free mandibular movements to help the dentist determine the "physiological relaxed position" and / or obtain a record of jaw position. Technical limitations: The cotton rolls or wax pads themselves have compression deformation and creep characteristics. Applying occlusal force will gradually reduce their height, leading to instability in vertical distance and significant errors. There is a complete lack of real-time objective monitoring of the occlusal force; the dentist can only judge the degree of muscle relaxation and jaw position stability through finger palpation or the patient's subjective description ("whether the teeth are touching," "where the force feels"). This is highly subjective and cannot be quantified. It is difficult to confirm whether the "relaxed" state has reached the true physiological position.

[0005] Deprogramming with rigid double occlusal splints (balancers, such as the Lucia jig or its variations): A rigid resin maxillary or mandibular (usually unilateral) splint is fabricated for the patient, covering the posterior region or the entire dental arch. The splint surface is smooth and flat (without cusps or fossae). After wearing, the patient is guided to perform small mandibular protrusion, lateral movements, or simply close their mouth until the splint contacts the jaw. The aim is to provide a smooth, undisturbed plane through mechanical separation, breaking the original abnormal occlusal locking pattern. Technical limitations: The height of this type of device (i.e., the vertical distance between the jaws provided) is a fixed value after fabrication (made by the laboratory based on a model), lacking a mechanism for real-time clinical adjustment according to individual patient responses. It cannot accurately adapt to the individualized needs of different patients' muscle tension and joint tightness; the efficacy is highly dependent on the accuracy of the initial fabrication of the device and the patient's subjective feedback, and it is difficult to objectively assess the deprogramming effect. Utility Model Content

[0006] The purpose of this invention is to provide an occlusal pad that allows for precise adjustment of the height between the upper and lower jaws, enhances the deprogramming effect, has an adjustable vertical distance, and features occlusal pressure monitoring.

[0007] To solve the above-mentioned technical problems, this utility model provides an occlusal pad with adjustable vertical distance and occlusal pressure monitoring function, including an maxillary base worn on the maxillary dentition and a mandibular base worn on the mandibular dentition. The maxillary base and the mandibular base are arranged opposite to each other, and an adjustment member is provided in the middle of the mandibular base so that the end of the adjustment member abuts against the maxillary base.

[0008] Furthermore, the adjusting component includes an adjusting end and a positioning end. The adjusting end is threadedly engaged with the mandibular base, and the positioning end has a spherical structure and is used to abut against the maxillary base.

[0009] Furthermore, an anti-sinking plate is provided between the adjusting end and the positioning end, and the diameter of the anti-sinking plate is larger than the diameter of the adjusting end.

[0010] Furthermore, an occlusal sensor is provided at the middle position of the maxillary base to detect the occlusal pressure between the maxillary and mandibular dentitions, and the occlusal sensor is matched with the positioning end.

[0011] Furthermore, it also includes a visualization interface, where the bite pressure detected by the bite sensor is transmitted to the visualization interface for display.

[0012] Furthermore, an adjustment hole or guide sleeve is provided at the middle position of the mandibular base, and the adjustment end is threadedly engaged with the adjustment hole or guide sleeve.

[0013] Furthermore, the maxillary base is fitted to the inside of the maxillary dentition, and the mandibular base is fitted to the inside of the mandibular dentition.

[0014] The beneficial effects of this utility model are as follows: By rotating the adjustment mechanism, the distance between the maxillary and mandibular baseplates can be precisely adjusted to meet the individualized vertical distance requirements of each patient. The occlusal sensor monitors and records occlusal pressure data in real time, providing doctors with objective and quantitative assessment data to ensure the deprogrammed process reaches the true physiological position. Simultaneously, the visual interface allows both patients and doctors to intuitively observe changes in occlusal pressure, further improving the accuracy and stability of treatment outcomes.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] like Figures 1-5 The present invention provides an occlusal pad with adjustable vertical distance and occlusal pressure monitoring function, including an maxillary base 2 worn on the maxillary dentition 1 and a mandibular base 4 worn on the mandibular dentition 3. The maxillary base 2 and the mandibular base 4 are arranged opposite to each other, and an adjustment member is provided in the middle of the mandibular base 4 so that the end of the adjustment member abuts against the maxillary base 2.

[0025] Specifically, the maxillary and mandibular bases are installed at the maxillary and mandibular dentitions respectively. The adjustment element connects to the mandibular base and abuts against the maxillary base, so that adjusting the height of the adjustment element can change the distance between the upper and lower bases, thereby adapting to the different muscle conditions of different patients.

[0026] Preferably, the adjusting member includes an adjusting end 5 and a positioning end 6. The adjusting end 5 is threadedly engaged with the mandibular base 4, and the positioning end 6 has a spherical structure and is used to abut against the maxillary base 2.

[0027] Specifically, when the adjusting end 5 rotates, the positioning end 6 rises and falls accordingly, precisely adjusting the distance between the upper and lower base brackets to ensure even distribution of biting pressure. At the same time, the spherical structure design of the positioning end effectively reduces friction and extends service life.

[0028] In one embodiment of this solution, the surface of the adjustment component is provided with micro-gradations, which facilitates doctors to accurately read the adjustment range and further improves treatment precision.

[0029] Preferably, an anti-sinking plate 7 is provided between the adjusting end 5 and the positioning end 6, and the diameter of the anti-sinking plate 7 is larger than the diameter of the adjusting end 5.

[0030] Specifically, the anti-sinking plate 7 can effectively prevent the adjustment end 5 from rotating excessively, ensuring adjustment stability. At the same time, its larger diameter design enhances the support of the overall structure and prevents the anti-sinking plate from entering the mandibular base and failing to play a limiting role, further improving the durability and safety of the occlusal pad.

[0031] The anti-sinking plate 7 is preferably made of high-strength medical-grade plastic, which is both lightweight and wear-resistant, ensuring that it will not deform during long-term use. Preferably, an occlusal sensor 8 is provided at the middle position of the maxillary base 2 to detect the occlusal pressure between the maxillary dentition 1 and the mandibular dentition 3, and the occlusal sensor 8 is matched with the positioning end 6.

[0032] Specifically, when the positioning end abuts against the occlusal sensor, the occlusal sensor detects the pressure value generated by the positioning end. At this time, the occlusal sensor 8 is connected to the external monitoring device through wireless data transmission to provide real-time feedback on changes in occlusal pressure, assisting doctors in accurately adjusting the occlusal splint, optimizing treatment effects, and improving patient comfort.

[0033] Among them, the bite sensor can be a pressure sensor.

[0034] Preferably, it also includes a visualization interface 9, on which the biting pressure detected by the biting sensor 8 is transmitted to the visualization interface 9 for display.

[0035] Specifically, the visual interface is wirelessly connected to the pressure sensor, allowing the visual interface to display the pressure values ​​detected by the pressure sensor in real time. Doctors can quickly adjust the height of the adjustment piece based on the data, thereby adjusting the distance between the upper and lower jaw bases to ensure balanced occlusal pressure and improve treatment results.

[0036] In one embodiment of this solution, the visualization interface can be a touch screen or an LCD screen, and the specific pressure values ​​can be displayed intuitively in digital or graphical form, which facilitates doctors to quickly make judgments and adjustments, further optimize treatment plans, and improve treatment efficiency.

[0037] Preferably, an adjustment hole or guide sleeve is provided in the middle of the mandibular base 4, and the adjustment end 5 is threadedly engaged with the adjustment hole or guide sleeve.

[0038] Specifically, the adjusting end 5 is tightly threaded into the adjusting hole or guide sleeve, ensuring stability and preventing deviation during rotation. This further improves adjustment accuracy and stability, while also facilitating quick operation by the doctor, reducing treatment time and enhancing the patient experience. The adjusting hole or guide sleeve is also made of high-strength medical-grade material, ensuring no wear during long-term use.

[0039] When using a guide sleeve, the guide sleeve is placed in the middle hole of the mandibular base and fixed by means of adhesive bonding or other methods.

[0040] Preferably, the maxillary base 2 is fitted to the inside of the maxillary dentition 1, and the mandibular base 4 is fitted to the inside of the mandibular dentition 3.

[0041] Specifically, the maxillary and mandibular denture bases fit into the inner side of the corresponding dentition, making the overall structure of the occlusal pad more compact, effectively dispersing occlusal forces and reducing local pressure concentration.

[0042] In one embodiment of this solution, the mandibular base and the maxillary base can be precisely customized through oral scanning, 3D modeling and other methods to ensure a high degree of fit with the patient's oral structure and improve wearing comfort.

[0043] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
