Description

Technical Field

[0001] This utility model relates to the field of orthodontic equipment technology, and in particular to a digital 3D molar intrusion device. Background Technology

[0002] In dental restoration and orthodontic treatment, due to reasons such as missing opposing teeth, some posterior teeth may over-erupt, thereby disrupting the stability and coordination of the overall occlusal plane. In order to restore normal occlusal function and aesthetics, it is necessary to apply orthodontic force to the over-erupted molars and press them down towards the alveolar bone.

[0003] One of the conventional methods to achieve molar intrusion is the use of various orthodontic appliances. These appliances generate and transmit a continuous intrusion force by connecting the target molar that needs to be intruded to the adjacent anchor teeth that provide support. However, in the slippery and functionally complex environment of the oral cavity, ensuring the stability of the appliance is a key prerequisite for achieving effective treatment.

[0004] Some existing orthodontic appliances have structural design flaws that result in insufficient retention. For example, the connection between the appliance and the teeth relies solely on simple bonding or universally sized bands. These connection methods are difficult to fully adapt to the complex morphology of individual teeth. During oral functional movements such as chewing and speaking, the complex force system applied to the appliance can easily cause slight displacement, rotation, or even complete dislodgement of the orthodontic appliance.

[0005] Any instability of the orthodontic appliance will directly lead to the interruption or deviation of the preset orthodontic force. This will not only greatly reduce the treatment efficiency and prolong the treatment period, but in more serious cases, it will also cause unexpected side effects on the anchor teeth. Therefore, how to improve the retention stability of the molar intrusion device in the oral cavity and ensure the accuracy and continuous action of the orthodontic force is a technical problem that urgently needs to be solved in this field.

[0006] Therefore, this utility model proposes a digital 3D molar depressor to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the problems existing in the digital 3D molar intrusion device, such as poor stability in the oral cavity due to poor retention structure design, easy displacement or dislodgement, resulting in interruption of orthodontic force and unreliable treatment effect, this utility model aims to provide a digital 3D molar intrusion device with improved structure that can effectively solve the above problems.

[0008] This utility model provides a digital 3D molar intrusion device, including an installation ring and an L-shaped toothed ring, as well as hook one, hook two, a limiting ring and a clamping ring. The L-shaped toothed ring is fixedly connected to one end of the installation ring, hook one is fixedly connected to the bottom left end of the L-shaped toothed ring, hook two is fixedly connected to the front right end of the L-shaped toothed ring, the limiting ring is fixedly connected to the left end of the outer wall of the L-shaped toothed ring, and the clamping ring is fixedly connected to the other end of the installation ring opposite to the L-shaped toothed ring. Through this integrated structural combination where the functional end and the anchoring end are separated and each enhances stability, they together constitute the main body of a highly stable orthodontic device.

[0009] Preferably, the mounting ring is a one-piece molded rod-shaped structure that is bent along the curvature of the user's dental arch. This shape can smoothly cross the dental arch, reduce irritation to the oral soft tissues, and at the same time serve as an elastic element to store and transmit orthodontic force.

[0010] Preferably, the L-shaped toothed ring is a hollow square ring structure, and the inner wall surface of the L-shaped toothed ring matches the outer surface of the target molar crown. This highly personalized matching ensures effective force transmission and a secure and comfortable fit.

[0011] Preferably, both hook one and hook two are hook-shaped bodies that curve inward and downward. This specific curvature is conducive to hooking into the undercut area of ​​the teeth, providing reliable mechanical locking force, and effectively preventing the device from dislodging towards the occlusal surface.

[0012] Preferably, as a further embodiment, the first hook and the second hook are located on the buccal side and lingual side of the L-shaped tooth ring, respectively. This arrangement significantly enhances the device's resistance to rotation and lateral dislodgement by simultaneously generating clamping force from both the inner and outer sides of the teeth.

[0013] Preferably, the clamping ring is a C-shaped ring structure with an opening, and the opening direction of the clamping ring is perpendicular to the extension direction of the mounting ring. This structure and opening direction design not only utilizes the elasticity of the material to achieve convenient engagement of the anchoring tooth, but also facilitates the user to perform the installation operation from the buccal or lingual side.

[0014] Preferably, the limiting ring is a C-shaped ring structure with an opening, and the opening of the limiting ring is oriented away from the body of the L-shaped toothed ring. This design provides elastic clamping force while effectively preventing the end edge of the ring from causing unnecessary friction or irritation to the adjacent gingival soft tissue.

[0015] Preferably, the inner wall surfaces of the limiting ring and the clamping ring are respectively matched with the outer surface contour of the corresponding anchored teeth. The precisely matched structure can increase the contact area and distribute the retention force evenly on the tooth surface, thereby improving the patient's wearing comfort while ensuring stable anchoring.

[0016] Preferably, the mounting ring, the L-shaped toothed ring, the first hook, the second hook, the limiting ring, and the clamping ring are integrally formed by digital design and 3D printing technology. The integral forming manufacturing method ensures the overall structural strength and highly personalized precision of the device, avoiding the weaknesses caused by traditional welding processes.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of existing molar indentation devices that are prone to rotation and dislodgement when subjected to chewing force or speaking due to unstable retention at the action end, resulting in interruption of orthodontic force and poor treatment effect. This is achieved by setting an L-shaped tooth ring that precisely fits the target molar, and extending hook one and hook two from the L-shaped tooth ring to form a multi-point circumferential clamping and fixation of the target molar. The invention greatly enhances the retention stability of the action end of the device, ensuring that the indentation force can be applied continuously and effectively, thereby significantly improving the treatment effect and predictability.

[0018] 2. This utility model, by adopting digital design and integrated 3D printing technology, and combining an L-shaped tooth ring, a clamping ring, and a limiting ring that are precisely fitted to the tooth surface at both ends of the mounting ring, solves the problems of traditional orthodontic appliances, which are poorly fitted to teeth, bulky, and have sharp edges due to non-personalized design, thus causing a strong foreign body sensation, damaging oral soft tissues, and resulting in low patient comfort. The device achieves a smooth shape, high fit, and uniform retention force, significantly reducing the patient's foreign body sensation, enhancing wearing comfort, and improving patient treatment compliance.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a digital 3D molar indentation device, which aims to solve the problems of insufficient retention force, poor stability, poor treatment effect, and strong foreign body sensation of oral appliances in the prior art.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 The digital 3D molar intrusion device includes a mounting ring 1 and a protective mechanism 2 integrated on the mounting ring 1. The mounting ring 1 serves as the main frame of the entire device, connecting and supporting the various functional components of the device. The protective mechanism 2 is used to securely fix the device to the user's teeth and apply precise orthodontic force to the target molars that need treatment.

[0024] Mounting ring 1 is a rod-shaped structure that extends integrally along the curvature of the user's dental arch. Its shape has been digitally designed to ensure that it can smoothly cross the user's dental arch and accurately connect the teeth at the active end and the anchoring end.

[0025] The protective mechanism 2 consists of multiple components that work together to achieve the functions of fixing and applying force to the device. The protective mechanism 2 includes an L-shaped toothed ring 21 fixedly connected to the right end of the mounting ring 1, a clamping ring 25 fixedly connected to the left end of the mounting ring 1, and a limiting ring 24 fixedly connected to the left end of the outer wall of the L-shaped toothed ring 21. Hook 1 22 and hook 23 are further fixedly connected to the L-shaped toothed ring 21. The L-shaped toothed ring 21, hook 1 22 and hook 23 together constitute the working unit of the device, which is used to directly act on the target molar that needs to be depressed. The clamping ring 25 and the limiting ring 24 together constitute the anchoring unit of the device, which is used to firmly fix the device to the adjacent healthy teeth and provide stable support for depressing the target molar.

[0026] Please refer to Figure 1 , Figure 3 and Figure 4The L-shaped toothed ring 21, as a component that directly acts on the target molar, is a hollow ring structure. Its inner wall is designed to match the outer surface of the crown of the target molar that needs to be depressed. This precise morphological matching is the basis for achieving effective force application. The L-shaped toothed ring 21 is fixedly connected to the right end of the mounting ring 1 via its right side.

[0027] To further enhance the retention effect of the L-shaped toothed ring 21, hook 1 22 is fixedly connected to the bottom left side of the L-shaped toothed ring 21, and hook 2 23 is fixedly connected to the front right side of the L-shaped toothed ring 21. The structural design of hook 1 22 and hook 2 23 allows them to hook or clamp onto the tooth body or gingival margin on both sides of the target molar after installation. By forming a circumferential clamping effect on the tooth from different directions, the L-shaped toothed ring 21 is greatly improved in terms of its resistance to dislodgement and rotation when subjected to chewing force or speaking.

[0028] Meanwhile, the limiting ring 24 is fixedly connected to the left end of the outer wall of the L-shaped toothed ring 21, while the clamping ring 25 is fixedly connected to the left end of the mounting ring 1. The structural design of the limiting ring 24 and the clamping ring 25 allows them to engage with the adjacent teeth that serve as anchorage support after installation. This dual-anchorage design provides a solid and reliable reaction force fulcrum for the pressure force transmitted through the mounting ring 1, thereby solving the problem that traditional single-point anchorage can easily lead to movement of the anchorage teeth or instability of the entire device.

[0029] As a preferred embodiment, in order to make the retention of the hooks more reliable, both hook 1 22 and hook 2 23 are hook-shaped bodies that bend inward and downward. This specific bending shape can better utilize the undercut area of ​​the crown or the shape of the cervical region of the tooth to form an effective mechanical lock and prevent the L-shaped tooth ring 21 from falling out towards the occlusal surface.

[0030] As a further preferred embodiment of the above scheme, hook 1 22 and hook 2 23 are located on the buccal side and lingual side of the L-shaped toothed ring 21, respectively. This layout design allows the two hooks to apply clamping force from both the inner and outer sides of the tooth at the same time. By forming a clamping and fixing of the target molar, the anti-rotation and anti-dislodgement capabilities of the device are further enhanced, ensuring the continuous stability of the pressure force.

[0031] As a preferred embodiment, in order to facilitate installation and provide good retention force, the clamping ring 25 is designed as a C-shaped ring structure with an opening, and the elasticity of the material itself can be used to fasten the clamping ring 25 to the anchoring tooth during installation.

[0032] As a further optimization of the structure of the clamping ring 25, the opening direction of the clamping ring 25 is perpendicular to the extension direction of the mounting ring 1. This design makes it easier for users or doctors to install and remove the anchored teeth from the buccal or lingual side, making the operation more intuitive and convenient.

[0033] As a preferred embodiment, the limiting ring 24 is also designed as a C-shaped ring structure with an opening to accommodate different tooth shapes and provide elastic clamping force.

[0034] As a further optimization of the structure of the limiting ring 24, the opening direction of the limiting ring 24 is oriented away from the main body of the L-shaped toothed ring 21. This opening orientation can effectively avoid unnecessary friction or irritation of the end edge of the ring to adjacent soft tissues such as gums or buccal mucosa, thus improving the patient's wearing comfort.

[0035] As a preferred embodiment, in order to maximize the retention effect and improve comfort, the inner wall surfaces of the limiting ring 24 and the clamping ring 25 are respectively matched with the outer surface contours of the corresponding anchored teeth. The precisely matched structure can increase the contact area between the device and the teeth, so that the retention force is evenly distributed on the tooth surface, avoiding stress concentration and damage to the anchored teeth, thereby improving the patient's wearing comfort.

[0036] As a preferred manufacturing solution of this utility model, the mounting ring 1, L-shaped toothed ring 21, hook one 22, hook two 23, limiting ring 24 and clamping ring 25 are integrally formed by digital design and 3D printing technology. The integral forming manufacturing method avoids the weaknesses caused by traditional welding or connection processes, ensures the overall structural strength and precision of the device, and also makes it possible to manufacture completely personalized complex orthodontic appliances.

[0037] Working principle: During installation and use, the L-shaped toothed ring 21 is first precisely fitted onto the target molar that needs to be depressed. At the same time, hook 1 22 and hook 2 23 hook or clamp the tooth body from both sides of the tooth, ensuring the high stability of the L-shaped toothed ring 21 in the vertical and horizontal directions. Next, the clamping ring 25 located at the other end of the mounting ring 1 and the limiting ring 24 connected to the L-shaped toothed ring 21 are respectively engaged and fastened to the adjacent healthy teeth that serve as anchorage. Since the mounting ring 1 has a specific elastic preset shape in its design, when the device is forcibly installed between the target tooth and the anchor tooth at different heights, the mounting ring 1 will undergo elastic deformation. It is precisely because of the continuous elastic restoring force generated by the mounting ring 1 that the L-shaped toothed ring 21 is precisely applied to the crown of the target molar, forming a gentle and continuous depressing force pointing towards the alveolar bone. With the protection of the entire synergistic retention system of the L-shaped toothed ring 21, hook 1 22, hook 2 23, limiting ring 24 and clamping ring 25, the depressing force can be transmitted stably and effectively, thereby guiding the target molar to undergo physiological remodeling in the alveolar bone and slowly move downwards towards the occlusal surface, ultimately achieving the therapeutic goal of depressing the molar and restoring normal occlusal height.
