Abstract
Description
Technical Field
[0001] The invention relates to the technical field of dental implant design and manufacturing, and in particular to a novel implant appearance structure. Background Art
[0002] In the field of dentistry, implants are widely used to replace missing teeth and restore chewing function and aesthetics for patients. The design and manufacture of implants is a comprehensive discipline that involves multiple aspects such as biomechanics, materials science, and dentistry. The stress distribution between the implant and bone interface is one of the key factors affecting the long-term stability and success rate of implants.
[0003] Traditional dental implants are mainly divided into two forms: cylindrical implants and conical implants. Cylindrical implants usually have a cylindrical appearance and are arranged with different types of threads on their surface; while conical implants present an oblique straight line or segmented oblique straight line that gradually tapers from the neck to the bottom. Both designs have achieved the initial stability and implantation torque requirements of the implant to a certain extent.
[0004] Deficiencies of existing technology: 1. Stress concentration problem: Existing cylindrical and conical implants may cause local stress to be excessively concentrated in certain areas after implantation, which will not only affect the bone health around the implant, but may also reduce the service life of the implant.
[0005] 2. Poor initial stability: Since traditional implants are relatively simple in shape and cannot completely imitate the complex anatomical structure of natural tooth roots, they provide limited stability in the initial stage of implantation, especially when bone density is low.
[0006] 3. The self-tapping performance is not ideal: For implants that need to self-drill into bone tissue, the existing morphological design fails to provide the most optimized geometry to reduce surgical difficulty and ensure good implantation results.
[0007] Therefore, the prior art has deficiencies and needs further improvement. Summary of the invention
[0008] In view of the problems existing in the prior art, the present invention provides a novel implant appearance structure.
[0009] To achieve the above object, the specific scheme of the present invention is as follows: The present invention provides a dental implant appearance structure, the appearance of the implant is composed of three connected arcs of different radii, which are divided into a neck arc, a body arc and a root arc, wherein the neck arc has a larger radius, the body arc is second, and the root arc is the smallest, forming a cone-like structure from the neck to the root of the implant, and the appearance structure is more rounded, similar to the root shape of a natural tooth, and is used to improve the stress distribution between the implant and the bone interface, reduce stress concentration, thereby improving the initial stability and implantation torque of the implant, and having good self-tapping properties to ensure that the implantation process is easier and enhance the mechanical stability of the implant; The arc portion of the neck of the implant is designed to be connected to an abutment or other repair components to ensure good biocompatibility and mechanical strength; The design of the implant tip takes into account the density of bone tissue and the initial stability of the implant, so that the implant can be firmly implanted into the patient's jawbone.
[0010] Furthermore, threads are arranged on the surface of the implant to strengthen the bonding force between the implant and surrounding bone tissue, thereby further improving the long-term stability of the implant.
[0011] Furthermore, in the three-stage arc design, the transition zone between the neck arc, the body arc and the root arc adopts a gradual curvature radius to achieve a smooth connection, thereby further reducing stress concentration points and improving the uniformity of stress distribution between the implant and the bone interface.
[0012] Furthermore, the surface treatment of the implant includes microstructural treatment or nano-coating, which is used to increase the surface roughness and bioactivity of the implant and promote faster and stronger bone integration.
[0013] Furthermore, the thread of the implant is designed to be asymmetrical, that is, the two sides of the thread are asymmetrical, one side is steeper and the other side is gentler, so as to optimize the self-tapping performance and reduce the resistance during the implantation process, while improving the initial stability.
[0014] Furthermore, the implant tip is designed with one or more guide grooves or incisions, which play a guiding role during the implantation process, ensuring that the implant can accurately enter the predetermined position, and help to disperse the insertion force and reduce the risk of damage to surrounding bone tissue.
[0015] Furthermore, the neck portion of the implant is designed with a unique sealing mechanism, including an elastic sealing ring or other forms of soft tissue sealing devices, to prevent bacteria from invading the implant-abutment interface and protect the implant environment from infection threats during the healing period; The implant is combined with intelligent monitoring functions. The built-in or external sensor components can monitor the physiological parameters around the implant including temperature, pH value, and pressure in real time, and send the data to external devices via wireless transmission, so that doctors can remotely track the status of the implant and the patient's recovery.
[0016] Furthermore, a hollow structure or a honeycomb support structure is provided inside the implant to reduce the weight of the implant while maintaining sufficient mechanical strength; this design not only reduces the amount of material used, but also improves the overall structural stability by optimizing the internal stress transfer path, and is suitable for patients with low bone density; The implant root is designed with an expandable anchoring device, which can be externally operated after implantation, including rotation or hydraulic expansion, to form a claw-like structure that penetrates deep into the surrounding bone tissue, greatly enhancing long-term stability and anti-rotation ability, and is particularly suitable for applications under soft bone conditions.
[0017] Furthermore, the connection between the implant neck and the abutment adopts a ball-and-socket joint or universal joint type flexible connection design, which allows angle adjustment within a certain range, ensuring the best occlusal relationship and aesthetic effect even in a complex oral environment, while reducing the risk of damage caused by uneven force; The implant body is designed with reinforcing ribs with spiral or polygonal cross-sections. These ribs are distributed along the length of the implant, increasing the overall rigidity of the implant and improving its torsional resistance. It exhibits better resistance to deformation when subjected to lateral forces and is suitable for clinical scenarios requiring high stability.
[0018] Furthermore, the root end of the implant is configured with an adaptive adjustment mechanism, which can automatically adjust the shape or size according to the different resistances encountered during the implantation process, ensuring that the tip of the implant is always in the most suitable penetration state, thereby improving the implantation efficiency and accuracy and reducing the difficulty of the operation.
[0019] The technical solution of the present invention has the following beneficial effects: 1. Improve stress distribution: The new implant effectively optimizes the stress distribution between the implant and the bone interface through its unique three-section arc design (neck arc, body arc and root arc). This design reduces local stress concentration, helps protect the health of the surrounding bones, and prevents bone resorption or implant loosening caused by excessive stress.
[0020] 2. Improve initial stability: The conical shape and rounded structure of the implant allow it to better adapt to the bone tissue during implantation, thereby enhancing initial stability. Good initial stability is crucial to the success of the implant because it provides a solid foundation for subsequent bone integration.
[0021] 3. Enhance self-attack: The design of the new implant not only takes into account biomechanical properties, but also pays special attention to the convenience of surgical operation. Its shape is more conducive to self-drilling into bone tissue, making the implantation process easier and smoother, reducing trauma to patients and reducing the difficulty of operation for doctors.
[0022] 4. Simulate natural tooth root morphology: The implant morphology proposed by the present invention is closer to the root morphology of natural teeth, which not only improves the repair effect from an aesthetic point of view, but more importantly promotes the healing of soft and hard tissues around the implant and improves the success rate of long-term use.
[0023] 5. Promote bone integration: The rounded design that conforms to the natural root curve makes the implant surface contact with the bone tissue more evenly, which is conducive to the attachment and growth of new bone cells, accelerates the bone integration process, and thus improves the overall stability and functionality of the implant.

[0029] Combination Figure 1-Figure 3 As shown, the present invention provides a novel implant appearance structure, the appearance of the implant is composed of three arcs of different radii connected together, namely, a neck arc 1, a body arc 2 and a root arc 3, wherein the neck arc 1 has a larger radius, the body arc is second, and the root arc is the smallest, forming a cone-like structure from the neck to the root of the implant, and the appearance structure is more rounded, similar to the root shape of a natural tooth, and is used to improve the stress distribution between the implant and the bone interface, reduce stress concentration, thereby improving the initial stability and implantation torque of the implant, and having good self-tapping properties to ensure easier implantation and enhance the mechanical stability of the implant; The arc 1 of the neck of the implant is designed to be connected to an abutment or other repair components to ensure good biocompatibility and mechanical strength; The design of the implant tip takes into account the density of bone tissue and the initial stability of the implant, so that the implant can be firmly implanted into the patient's jawbone.
[0030] The surface of the implant is arranged with threads to strengthen the bonding force between the implant and the surrounding bone tissue, thereby further improving the long-term stability of the implant.
[0031] In the three-stage arc design, the transition zone between the neck arc 1, the body arc 2 and the root arc 3 adopts a gradual curvature radius to achieve a smooth connection, thereby further reducing stress concentration points and improving the uniformity of stress distribution between the implant and the bone interface.
[0032] The surface treatment of the implant includes microstructural treatment or nano-coating, which is used to increase the surface roughness and bioactivity of the implant and promote faster and stronger bone integration.
[0033] The thread of the implant is designed to be asymmetrical, that is, the two sides of the thread are asymmetrical, one side is steeper and the other side is flatter, so as to optimize the self-tapping performance and reduce the resistance during the implantation process, while improving the initial stability.
[0034] The implant tip is designed with one or more guide grooves or incisions, which play a guiding role during the implantation process, ensuring that the implant can accurately enter the predetermined position, and help to disperse the insertion force and reduce the risk of damage to surrounding bone tissue.
[0035] The neck portion of the implant is designed with a unique sealing mechanism, including an elastic sealing ring or other forms of soft tissue sealing devices, to prevent bacteria from invading the implant-abutment interface and protect the implant environment from infection threats during the healing period; The implant is combined with intelligent monitoring functions. The built-in or external sensor components can monitor the physiological parameters around the implant including temperature, pH value, and pressure in real time, and send the data to external devices via wireless transmission, so that doctors can remotely track the status of the implant and the patient's recovery.
[0036] The implant is provided with a hollow structure or a honeycomb support structure inside to reduce the weight of the implant while maintaining sufficient mechanical strength; this design not only reduces the amount of material used, but also improves the overall structural stability by optimizing the internal stress transfer path, and is suitable for patients with low bone density; The implant root is designed with an expandable anchoring device, which can be externally operated after implantation, including rotation or hydraulic expansion, to form a claw-like structure that penetrates deep into the surrounding bone tissue, greatly enhancing long-term stability and anti-rotation ability, and is particularly suitable for applications under soft bone conditions.
[0037] The connection between the implant neck and the base adopts a ball-and-socket joint or universal joint-type flexible connection design, which allows angle adjustment within a certain range, ensuring the best occlusal relationship and aesthetic effect even in a complex oral environment, while reducing the risk of damage caused by uneven force; The implant body is designed with reinforcing ribs with spiral or polygonal cross-sections. These ribs are distributed along the length of the implant, increasing the overall rigidity of the implant and improving its torsional resistance.

[0038] The root end of the implant is equipped with an adaptive adjustment mechanism, which can automatically adjust the shape or size according to the different resistances encountered during the implantation process, ensuring that the implant tip is always in the most suitable penetration state, thereby improving implantation efficiency and accuracy and reducing surgical difficulty.
[0039] The principle of the present invention is as follows: How it works 1. Stress distribution optimization mechanism Three-section arc design: The implant imitates the morphological characteristics of natural tooth roots through a unique geometric structure consisting of a neck arc 1, a body arc 2, and a root arc 3. This design allows for a more uniform contact between the implant and the bone interface after implantation, thereby effectively dispersing the occlusal force and other external forces applied to the implant and reducing local stress concentration points.
[0040] Gradual curvature transition zone: The neck arc 1, body arc 2 and root arc 3 are smoothly connected by a gradual curvature radius, which further reduces stress concentration, ensures that the force can be more evenly distributed on the implant and surrounding bone tissue, and reduces the risk of bone resorption caused by excessive stress.
[0041] 2. Achieving initial stability Cone-like appearance and bone tissue adaptability: The conical design of the implant gradually tapers from the neck to the root, making it easier to enter the predetermined position during implantation, and can fit closely to the bone wall, providing good initial stability. This not only helps with positioning during surgery, but also lays the foundation for subsequent bone integration.
[0042] Enhanced self-tapping: The implant's shape is designed with self-tapping in mind, meaning it can be implanted without pre-drilling. This feature simplifies the procedure, reduces surgery time and patient discomfort, while ensuring implant stability after implantation. In addition, the asymmetric thread design further optimizes self-tapping performance and reduces resistance during implantation.
[0043] 3. Promote bone integration Surface treatment technology: The surface of the implant may be microstructured or nano-coated to increase roughness and bioactivity, promoting faster and stronger bone integration. These surface treatments provide additional support points for new bone cells, accelerating the bone integration process.
[0044] Internal structure optimization: The implant is equipped with a hollow structure or honeycomb support framework, which reduces the weight while maintaining sufficient mechanical strength, optimizes the internal stress transfer path, and improves the overall structural stability. It is especially suitable for patients with low bone density.
[0045] 4. Long-term functional protection Maintaining long-term stability: Due to the combined effect of all the above factors - optimized stress distribution, establishment of initial stability and effective bone integration - the implant can maintain its functionality and aesthetics for a longer period of time and meet the patient's daily physiological needs such as chewing.
[0046] Dynamic adjustment function: The root end of the implant is equipped with an adaptive adjustment mechanism, which can automatically adjust the shape or size according to the different resistances encountered during the implantation process, ensuring that the tip of the implant is always in the most suitable penetration state, thereby improving the efficiency and accuracy of the implantation and reducing the difficulty of the operation.
[0047] 5. Innovative connection mechanism Flexible connection design: The connection between the implant neck and the abutment adopts a ball-and-socket joint or universal joint-type flexible connection design, which allows angle adjustment within a certain range, ensuring the best occlusal relationship and aesthetic effect even in complex oral environments, while reducing the risk of damage caused by uneven force.
[0048] In summary, the new implant invented by the present invention improves the performance of the implant on multiple levels, including mechanical properties, surgical convenience and biological response, through its innovative appearance design and internal structure optimization, bringing significant progress to the field of dental implants.
