Description

Technical Field

[0001] The utility model relates to the field of oral orthodontic treatment equipment, and in particular to a 3D-printed auxiliary anterior teeth depression and retraction jaw pad device. Background Art

[0002] In the field of orthodontic treatment, non-invasive treatment methods, such as posterior HE pads, play an important role in adjusting the three-dimensional positional relationship between the upper and lower jaws, improving tooth alignment and occlusion. For patients with anterior crossbite, posterior HE pads are often used in traditional orthodontic treatment to release the lock between the anterior teeth and guide the mandible to retreat to a healthier sagittal position. However, existing posterior HE pads have several limitations in design and application.

[0003] First, the traditional HE pad is large in size, which gives patients a significant foreign body sensation when worn, affecting the wearing comfort. In addition, due to its large size, a large range of chairside adjustments are required when wearing it, which is not only time-consuming but also inefficient. Secondly, the retention design of the traditional HE pad mainly relies on interproximal hooks and shear head clips. When these retention methods are used in conjunction with fixed orthodontic appliances such as archwires and brackets, their retention effects are often unsatisfactory, especially when eating. Furthermore, the production process of the traditional HE pad is cumbersome, including making plaster models, disinfection, HE frame placement, manual bending of archwires, manual filling of self-curing resin bases, and other steps, which not only increases the production cost, but also prolongs the patient's waiting time.

[0004] With the rapid development of digital technology, the field of orthodontic treatment has also ushered in changes. Digital models use intraoral computer optical impression technology to achieve rapid acquisition and transmission of oral data, greatly simplifying clinical procedures. This change not only eliminates the need for impression disinfection, packaging, and physical transfer to the laboratory, but also improves the efficiency of communication between doctors, dental technicians, and patients. In addition, when the HE pad is lost or damaged, the stored digital data can be quickly used to make a new HE pad without the need to re-make the impression, greatly saving patients time and costs. In view of this, this application is hereby proposed. Utility Model Content

[0029] Example

[0030] Please refer to Figure 1-Figure 4 The present embodiment discloses a 3D-printed auxiliary anterior teeth depression and retraction jaw pad device, comprising a 3D-printed integrally formed jaw pad body 1, an L-shaped depression rod 2 being provided on the jaw pad body 1, traction balls 3 being provided on both sides of the jaw pad body 1, and pressure sensors being embedded in the corresponding traction balls 3; the pressure sensors are embedded in the traction balls to monitor the traction force applied to the anterior teeth to ensure the safety and effectiveness of the treatment process.

[0031] In the process of oral orthodontic treatment, the auxiliary anterior teeth depression and retraction jaw pad device based on 3D printing provided in this embodiment plays an important role. First, the patient's oral digital model is obtained by intraoral computer optical impression technology to ensure the accurate matching of the jaw pad body 1. In this embodiment, the patient's oral three-dimensional data can be obtained by an intraoral scanner. After obtaining the three-dimensional data, a personalized jaw pad body model can be designed by 3D modeling software, the model data is imported into the 3D printer, and a suitable biocompatible material is selected for one-piece printing. The use of 3D printing technology not only simplifies the production process of traditional jaw pads, but also improves the production accuracy and efficiency. The one-piece design ensures the structural stability and wearing comfort of the jaw pad body. By providing an L-shaped depression rod 2 on the jaw pad body 1, traction balls 3 are provided on both sides of the jaw pad body 1, and pressure sensors are embedded in the corresponding traction balls 3; it can be ensured that the L-shaped depression rod 2 is used to load vertical force on the anterior tooth area to depress the anterior teeth, and the traction balls 3 on both sides can be connected to an external traction device to apply traction to help the anterior teeth retract, and the bilateral posterior tooth areas are connected through the jaw pad body 1 to form group tooth support. When designing the jaw pad body 1, ensure that the bilateral posterior tooth areas are connected through the jaw pad body 1 to form a stable tooth support structure. The purpose is to protect the support teeth while ensuring the stability and reliability of the treatment effect. Through the above settings, the stable connection of the bilateral posterior tooth areas constructs a reliable tooth support. This structure not only protects the support teeth from unnecessary damage, but also improves the stability and reliability of the entire orthodontic treatment process.

[0032] In the above implementation, more specifically, the auxiliary anterior teeth depression and retraction jaw pad device based on 3D printing provided in this embodiment plays an important role in the process of oral orthodontic treatment. First, the patient's oral digital model is obtained through intraoral computer optical impression technology to ensure the accurate matching of the jaw pad body 1. Then, the jaw pad body 1, L-shaped depression rod 2 and traction ball 3 are integrally formed using 3D printing technology to ensure the stability and durability of the device.

[0033] During the treatment, the patient wears the device, and the horizontal section 22 of the L-shaped depression rod 2 contacts the patient's front teeth, applying precise depression force through the vertical section 21. At the same time, the traction balls 3 on both sides are connected to the external traction device to apply appropriate traction force to the front teeth to achieve retraction. During the treatment, the embedded pressure sensor monitors the orthodontic correction force value in real time and sends it to the doctor and the patient's mobile phone through a wireless transmission device, so as to adjust the treatment plan in time.

[0034] In general, the 3D printing-based auxiliary anterior teeth lowering and retraction jaw pad device provided in this embodiment can be customized through 3D printing technology. Combined with the principles of mechanics, it can effectively assist in the lowering and retraction of anterior teeth, while protecting the anchor teeth and improving the stability and efficiency of orthodontic treatment.

[0035] Furthermore, the L-shaped depression rod 2 is composed of a vertical section 21 and a horizontal section 22, and the L-shaped depression rod 2 and the jaw pad main body 1 are integrally formed by 3D printing. Specifically, during the design process of the jaw pad main body 1, the position and shape of the L-shaped depression rod 2 are determined according to the patient's dental condition and treatment needs. The L-shaped depression rod 2 is composed of a vertical section 21 and a horizontal section 22, and is 3D printed together with the jaw pad main body 1 to ensure that the two are tightly connected. Through the above design, the L-shaped depression rod 2 can accurately apply vertical force to the front teeth area, thereby effectively adjusting the position of the front teeth. Compared with traditional methods, it is more accurate and efficient, and helps to achieve better treatment results.

[0036] Furthermore, the jaw pad body 1 is designed with an embedded power supply and a wireless transmission device, which are used to send the orthodontic correction force value monitored by the pressure sensor to the mobile phone in real time. The traction ball 3 structure is designed and printed on both sides of the jaw pad body 1, and the pressure sensor is embedded in the traction ball 3. Through the circuit connection, it is ensured that the pressure sensor can monitor the orthodontic correction force in real time and transmit the data to the embedded power supply and wireless transmission device. The setting of the traction ball 3 provides the patient with just the right traction force, which helps to achieve the retraction of the anterior teeth. At the same time, the application of the pressure sensor enables doctors and patients to monitor the changes in orthodontic correction force in real time to ensure the safety and effectiveness of the treatment process.

[0037] Furthermore, the horizontal section 22 extends horizontally from the end of the vertical section 21 to the front teeth area and can contact the surface of the patient's front teeth. The front end of the horizontal section 22 is designed to be bendable or adjustable to adapt to the shape and position of the front teeth of different patients. In the specific implementation process, this can be achieved by using flexible materials. The bendable or adjustable design of the horizontal section 22 improves the adaptability and comfort of the jaw pad, ensuring that the L-shaped depression rod 2 can fit closely to the surface of the patient's front teeth, thereby achieving more effective treatment. The maximization of the treatment effect and the comfort of the patient are ensured.

[0038] Furthermore, a U-shaped groove 23 is provided on the L-shaped depression rod 2, and a pressure sensor is embedded in the U-shaped groove 23. The horizontal section 22 of the L-shaped depression rod 2 is in contact with the patient's front teeth, and the depression force is transmitted through the vertical section 21 to achieve accurate depression of the front teeth. The traction ball 3 applies appropriate traction through an external traction device to assist in the retraction of the front teeth. The pressure sensor embedded in the traction ball 3 and the U-shaped groove 23 of the L-shaped depression rod 2 monitors the orthodontic correction force value in real time, and sends it to the mobile phone in real time through the embedded power supply and wireless transmission device, so that doctors and patients can view it at any time, so as to adjust the treatment plan in time.

[0039] By adopting the above scheme, the beneficial effects brought about by this embodiment are as follows: by using 3D printing integrated molding technology, the production process of the jaw pad is significantly simplified, which not only greatly improves the production efficiency, but also allows patients to enjoy a shorter waiting time. The design of the L-shaped depression rod can apply vertical force to the anterior tooth area, thereby realizing fine adjustment of the position of the anterior teeth. At the same time, in conjunction with the traction ball setting on both sides, it provides the patient with just the right traction force, promoting the smooth realization of the anterior teeth retraction. In addition, the introduction of digital design and manufacturing processes has greatly improved the communication efficiency between doctors, dental technicians and patients, reduced the operation time beside the clinical chair, and made the entire treatment process more efficient and smooth. The bilateral posterior tooth area is firmly connected through the jaw pad to construct a solid group tooth support, which not only comprehensively protects the support teeth, but also fully ensures the stability and reliability of the treatment effect. This series of technical advantages undoubtedly brings patients a more efficient and comfortable treatment experience.

[0040] The above is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
