Description

Technical Field

[0001] This invention relates to the field of dental technology, specifically to an implant bridge for dental implant restoration. Background Technology

[0002] Dental implant restoration technology, as an ideal solution for replacing missing teeth, has been widely used in clinical practice and has achieved a high success rate. This technology achieves osseointegration by implanting artificial implants into the jawbone, and then connects the crowns through superstructures such as implant bridges, thereby restoring the chewing function and aesthetic appearance of the teeth. With the increasing global awareness of oral health and the intensifying trend of population aging, the dental implant market continues to grow. However, the connection stability between implants and bridges remains a key technical bottleneck that restricts the long-term maintenance of restoration results.

[0003] In existing technologies, the problem of implant angle deflection has long plagued clinical practice. This deflection mainly stems from three factors: first, surgical operation deviations, such as inaccurate drilling positions or poor control of implant placement angles; second, differences in patient bone conditions, where a single fixation structure cannot compensate for individual differences in bone anatomy when alveolar bone thickness is uneven or jaw deformities exist; and third, defects in biomechanical design, where traditional implant bridges rely on single bolts or simple slot fixation, lacking multi-dimensional limiting mechanisms, making them prone to micro-movement under repeated masticatory forces, which in turn leads to implant angle deflection. Studies have shown that implant angle deflection exceeding 5° may cause stress concentration, significantly increasing the risk of surrounding bone resorption, and even leading to implant loosening and failure.

[0004] Meanwhile, the loosening of locking bolts has become another important factor affecting the long-term stability of restorations. Clinical data shows that the loosening rate of screw-retained restorations is as high as 15% to 20% within 5 years. The main reasons for this include: uneven distribution of interlocking stress, and the inability of traditional bolt designs to buffer the instantaneous impact force during interlocking, leading to fatigue of the threaded connection; lack of effective anti-loosening mechanisms, as conventional screws are only fixed by friction, which is prone to preload decay under long-term cyclic loads. Although existing technologies have adopted a combination of Morse taper and internal hexagonal design to enhance stability, this structure still cannot completely solve the micro-gap problem under multi-directional forces, and the high processing complexity leads to increased costs.

[0005] Current mainstream fixation methods have significant technical limitations: adhesive fixation is aesthetically pleasing but difficult to disassemble, and adhesive residue can easily induce inflammation; traditional screw fixation is convenient for maintenance, but exposed metal affects aesthetics and has a high rate of loosening. These problems not only require patients to have frequent follow-up visits for adjustments, but in severe cases, a second surgery is required to remove the implant, significantly increasing medical costs and patient suffering. Therefore, the development of implant bridging structures that combine precise angle control and long-term anti-loosening functions has become an urgent need to improve the long-term success rate of implant restoration. Summary of the Invention

[0006] The purpose of this invention is to provide an implant bridge for dental implant restoration, in order to solve the problems mentioned in the background art, such as insufficient stability of the connection between the implant and the bridge, especially the easy loosening of the implant angle and locking bolts, as well as the poor aesthetics and maintenance convenience of the existing fixation methods.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an implant bridge for dental implant restoration, comprising a base body, a base plate provided on the lower surface of the base body, the base plate being fixedly connected to the base body by fixing bolts, the outer surfaces of the base body and the base plate being penetrated by mounting bolts, a limiting seat being fixedly provided on the upper surface of the base plate, and a threaded hole being provided at the upper end of the limiting seat, a sliding support ring being provided inside the side surface of the base body, and a limiting frame being fixedly provided on the upper surface of the support ring, a positioning groove being provided on the upper surface of the base body, and an implant being installed in the base body through the positioning groove, a clearance hole being provided inside the implant, and a slot being provided on the upper end face of the implant;

[0008] A limiting hole is formed on the inner surface of the clearance hole inside the implant, and the clearance hole inside the implant is penetrated by a locking bolt. A clearance groove is formed inside the lower end of the locking bolt, and a hollow docking post is fixedly installed at the upper end of the locking bolt. A sliding limiting rod is installed inside the upper end of the locking bolt, and a sliding rod is fixedly installed inside the upper side surface of the locking bolt. A sliding locking rod is installed at the upper end of the docking post.

[0009] Preferably, the base and the bottom plate are connected to the alveolar bone by mounting bolts, and the lower end face of the fixing bolt is flush with the lower surface of the bottom plate.

[0010] Using the above technical solution, the substrate and the base plate are directly anchored to the alveolar bone by mounting bolts, forming a stable overall support structure. At the same time, the lower end face of the fixing bolt is flush with the base plate, avoiding the bolt protruding and irritating the surrounding tissues of the alveolar bone, thus improving the patient's wearing comfort.

[0011] Preferably, a gap is left between the outer surface of the limiting seat and the inner surface of the substrate, and the upper end of the threaded hole is in contact with the lower surface of the implant.

[0012] Using the above technical solution, the gap between the limiting seat and the base provides space for the sliding adjustment of the support ring and the limiting frame to adapt to different alveolar bone conditions. The threaded hole fits the lower surface of the implant, which can limit the horizontal displacement of the implant and prevent angular displacement caused by loosening.

[0013] Preferably, a spring is connected between the support ring and the upper surface of the base plate, the inner surface of the limiting frame is in contact with the outer surface of the limiting seat, the outer surface of the limiting frame is in contact with the inner surface of the base, and the upper end of the limiting frame is engaged with the slot.

[0014] Using the above technical solution, the support ring provides an upward clamping force through the spring, so that the limiting frame restricts the horizontal displacement of the implant through the "double fit" structure. At the same time, the upper end of the limiting frame engages with the slot, directly constraining the circumferential rotation of the implant and effectively preventing angular deflection caused by chewing force.

[0015] Preferably, the locking bolt and the threaded hole are concentrically arranged, and the locking bolt and the threaded hole are threadedly connected. The upper end of the docking post is designed as a frustum, and the lower outer surface of the docking post is in contact with the upper surface of the implant.

[0016] Using the above technical solution, the locking bolt and the threaded hole are connected by concentric threads to ensure that the implant is installed along the vertical axis and avoid initial angle deviation. The lower end of the docking post fits against the upper end face of the implant, which can disperse occlusal stress and reduce thread fatigue. Its frustum-shaped upper end is hidden inside the crown to avoid metal exposure affecting aesthetics.

[0017] Preferably, the end of the limiting rod facing outward from the locking bolt is engaged with the limiting hole, and a groove is provided on the outer surface of the limiting rod.

[0018] Using the above technical solution, the outer end of the limiting rod engages with the limiting hole to form a two-stage anti-loosening structure, preventing the locking bolt from rotating and loosening. The sliding groove provides guidance for the sliding of the limiting rod, ensuring the stability of the engagement state.

[0019] Preferably, one end of the slide rod is located inside the slide groove, and the limiting rod is slidably connected to the slide rod through the slide groove, and a spring is connected between the slide rod and the slide groove.

[0020] Using the above technical solution, the sliding fit between the slide rod and the slide groove, as well as the spring force, provide a continuous restoring force for the limit rod.

[0021] Preferably, the lower end of the locking rod is a frustum-shaped design with a smaller bottom and a larger top, and the lower end of the locking rod is in contact with the inner bottom surface of the clearance groove.

[0022] Using the above technical solution, the lower end of the locking rod, which is frustoconical, fits against the bottom surface of the relief groove. When the crown is pressed down, it can squeeze the inner end of the limiting rod, forcing the outer end of the limiting rod to be more tightly locked into the limiting hole, forming a dynamic anti-loosening mechanism and improving the long-term stability of the restoration.

[0023] Preferably, a spring is connected between the locking rod and the docking post, and the lower outer surface of the locking rod is in contact with the end of the limiting rod facing the inside of the docking post.

[0024] Using the above technical solution, the spring between the locking rod and the docking post provides continuous downward pressure, and the limiting rod is squeezed by the frustum-shaped lower end, so that the engagement state between the limiting rod and the limiting hole remains stable during chewing, thus achieving long-term anti-loosening.

[0025] Compared with the prior art, the beneficial effects of the present invention are: the dental implant restoration implant bridge:

[0026] 1. The base plate engages with the implant through the positioning groove, providing an initial installation reference for the implant. The base plate is rigidly fixed to the base plate by fixing bolts, and the lower end face of the fixing bolts is flush with the lower surface of the base plate. This ensures the stability of the connection between the two and avoids the bolts protruding and irritating the surrounding alveolar bone tissue. At the same time, the base plate and the base plate are directly connected to the alveolar bone by the mounting bolts, forming a stable overall support structure, which lays the foundation for subsequent angle control.

[0027] Furthermore, the upper end of the threaded hole and the positioning groove fits tightly against the lower surface of the implant, which can limit the displacement of the implant and prevent angular deviation caused indirectly by loosening. At the same time, the threaded hole and the locking bolt are concentrically set and threadedly connected, which further ensures that the implant is installed along the vertical axis and avoids initial angular deviation.

[0028] Furthermore, the inner side of the limiting frame fits the outer side of the limiting seat, and the outer side fits the inner side of the matrix, forming a "double fit" guiding structure, which can limit the horizontal displacement of the implant. In addition, the upper end of the limiting frame engages with the slot of the implant, which can directly constrain the circumferential rotation of the implant, effectively prevent angular deflection under the action of chewing force, and significantly reduce the probability of surrounding bone resorption.

[0029] 2. The locking bolt passes through the clearance hole of the implant and is threadedly connected to the threaded hole of the limiting seat to form a first-level thread fixation. At the same time, the outer surface of the lower end of the docking post at the upper end of the locking bolt fits against the upper end face of the implant. The frustum-shaped design at the upper end of the docking post not only avoids metal exposure affecting aesthetics, but also further disperses the interlocking stress through end face fit, reducing fatigue damage to the threaded connection.

[0030] Furthermore, a two-stage anti-loosening structure is formed by engaging the limiting hole on the surface of the inner side of the implant with the outer end of the limiting rod that is slidably installed inside the locking bolt. The sliding groove on the outer surface of the limiting rod is slidably connected with the sliding rod fixed inside the locking bolt, and the spring connected between the sliding rod and the sliding groove can provide a continuous outward pushing force for the limiting rod, ensuring that the limiting rod and the limiting hole are always tightly engaged, avoiding the preload decay caused by long-term periodic loads.

[0031] Furthermore, when installing the crown, the locking rod can be pushed down continuously, and the inner end of the limiting rod is squeezed by the frustum-shaped lower end face, forcing the limiting rod to remain in an extended state, further strengthening the engagement effect with the limiting hole and greatly improving the long-term stability of the restoration;

[0032] 3. The "screw + snap-fit" combination retention method eliminates the need for adhesive, avoiding the risk of adhesive residue causing gingivitis and solving the problem of difficult disassembly of traditional adhesive retention. During subsequent follow-up maintenance, the implant can be removed simply by removing the locking rod and locking bolt, making the operation convenient and reducing the pain of secondary surgery for patients.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-10 The present invention provides a technical solution: an implant bridge for dental implant restoration.

[0046] Example 1: This example discloses: a base 1, a base plate 2 on the lower surface of the base 1, the base plate 2 being fixedly connected to the base 1 by fixing bolts 3, the outer surfaces of the base 1 and the base plate 2 being penetrated by mounting bolts 4, a limiting seat 5 being fixedly provided on the upper surface of the base plate 2, and a threaded hole 6 being provided at the upper end of the limiting seat 5, a sliding support ring 7 being provided inside the side surface of the base 1, and a limiting frame 8 being fixedly provided on the upper surface of the support ring 7, a positioning groove 11 being provided on the upper surface of the base 1, and an implant 9 being installed in the base 1 through the positioning groove 11, a clearance hole 10 being provided inside the implant 9, and a slot 12 being provided on the upper end face of the implant 9;

[0047] The base 1 and the base plate 2 are connected to the alveolar bone by mounting bolts 4, and the lower end face of the fixing bolt 3 is flush with the lower surface of the base plate 2.

[0048] A gap is left between the outer surface of the limiting seat 5 and the inner surface of the base 1, and the upper end of the threaded hole 6 is in contact with the lower surface of the implant 9.

[0049] A spring is connected between the support ring 7 and the upper surface of the base plate 2. The inner surface of the limiting frame 8 is in contact with the outer surface of the limiting seat 5, and the outer surface of the limiting frame 8 is in contact with the inner surface of the base 1. The upper end of the limiting frame 8 is engaged with the slot 12.

[0050] The lower surface of the base 1 is fixed to the base plate 2 by fixing bolts 3. The lower end face of the fixing bolts 3 is flush with the lower surface of the base plate 2 to avoid the protruding part from irritating the tissues around the alveolar bone. The base 1 and the base plate 2 are directly anchored to the alveolar bone by mounting bolts 4 penetrating through the outer surface, forming a stable bottom support platform.

[0051] A positioning groove 11 is formed on the upper surface of the substrate 1. The implant 9 is installed by engaging the positioning groove 11. The upper end of the positioning groove 11 is tightly fitted with the lower surface of the implant 9 to restrict its displacement and provide an initial installation reference for the implant 9.

[0052] The upper surface of the base plate 2 is fixed with a limiting seat 5, and a threaded hole 6 is opened at its upper end. The upper end of the threaded hole 6 fits against the lower surface of the implant 9, further restricting the horizontal movement of the implant 9, and providing a positioning reference for the subsequent installation of the locking bolt 14.

[0053] A gap is left between the outer side of the limiting seat 5 and the inner side of the base 1, allowing the support ring 7 and the limiting frame 8 to slide within the gap to adapt to the fine-tuning needs under different bone conditions. The support ring 7 is installed inside the side surface of the base 1 and can slide up and down. A spring connects it to the upper surface of the base plate 2. The elastic force of the spring causes the support ring 7 to continuously press against the limiting frame 8 upward. The limiting frame 8 is fixed to the upper surface of the support ring 7, with its inner surface adhering to the outer side of the limiting seat 5 and its outer surface adhering to the inner side of the base 1, forming a "double-adhesion" guide structure that strictly limits the horizontal displacement of the implant 9.

[0054] The upper end of the limiting frame 8 engages with the slot 12 on the upper surface of the implant 9, directly constraining the circumferential rotation of the implant 9. When chewing force is applied to the implant 9, the limiting frame 8 prevents it from rotating through the slot 12, reducing the risk of angular deflection.

[0055] Example 2: This example discloses the following based on Example 1: A limiting hole 13 is opened on the inner surface of the clearance hole 10 on the inner side of the implant 9, and the clearance hole 10 on the inner side of the implant 9 is penetrated by a locking bolt 14. A clearance groove 15 is opened inside the lower end of the locking bolt 14, and a hollow docking post 16 is fixedly installed on the upper end of the locking bolt 14. A sliding limiting rod 17 is installed inside the upper end of the locking bolt 14, and a sliding rod 19 is fixedly installed inside the upper side surface of the locking bolt 14. A sliding locking rod 20 is installed on the upper end of the docking post 16.

[0056] The locking bolt 14 and the threaded hole 6 are concentrically set and are threadedly connected. The upper end of the docking post 16 is designed as a frustum, and the lower outer surface of the docking post 16 is in contact with the upper surface of the implant 9.

[0057] The end of the limiting rod 17 facing the outside of the locking bolt 14 is engaged with the limiting hole 13, and the outer surface of the limiting rod 17 is provided with a sliding groove 18;

[0058] One end of the slide rod 19 is located inside the slide groove 18, and the limiting rod 17 is slidably connected to the slide rod 19 through the slide groove 18, and a spring is connected between the slide rod 19 and the slide groove 18;

[0059] The lower end of the locking rod 20 is a frustum-shaped design with a smaller bottom and a larger top, and the lower end of the locking rod 20 fits against the inner bottom surface of the relief groove 15.

[0060] A spring is connected between the locking rod 20 and the docking post 16, and the lower outer surface of the locking rod 20 is in contact with the end of the limiting rod 17 facing the inside of the docking post 16;

[0061] The locking bolt 14 passes through the clearance hole 10 inside the implant 9 and is concentrically threaded to the threaded hole 6 of the limiting seat 5 to form a first-level mechanical fixation, rigidly connecting the implant 9 to the base plate 2. The lower end of the locking bolt 14 has a clearance groove 15 to provide space for the movement of the limiting rod 17. The upper end of the bolt 14 is fixed with a hollow docking post 16. The lower outer surface of the docking post 16 fits against the upper end face of the implant 9 to disperse the occlusal stress and avoid fatigue of the threaded connection due to concentrated load. The upper end of the docking post 16 is designed as a frustum shape, which can be hidden inside the crown to avoid metal exposure affecting aesthetics. The frustum shape structure also increases the contact area and evenly transmits the chewing force to the implant 9, reducing local stress concentration.

[0062] A limiting hole 13 is opened on the surface of the inner clearance hole 10 of the implant 9. A limiting rod 17 is slidably installed inside the upper end of the locking bolt 14. The outer end of the limiting rod 17 is stuck into the limiting hole 13 under the action of external force to prevent the locking bolt 14 from rotating and loosening. A sliding groove 18 is opened on the outer surface of the limiting rod 17. A sliding rod 19 is fixed inside the side surface of the locking bolt 14. The sliding rod 19 is inserted into the sliding groove 18 and connected by a spring so that the limiting rod 17 can slide along the sliding groove 18 when the pressure is lost, while the spring continuously provides the restoring elastic force.

[0063] The locking rod 20 is installed on the upper end of the docking post 16. Its lower end is a frustum-shaped cone with a smaller bottom and a larger top. It fits against the bottom surface of the relief groove 15 inside the docking post 16 and is connected to the docking post 16 by a spring. When the crown is installed, the crown presses down on the locking rod 20, causing it to slide downward. The lower end of the frustum-shaped cone squeezes the end of the limiting rod 17 facing the inside of the docking post 16, forcing the outer end of the limiting rod 17 to be more tightly inserted into the limiting hole 13, further enhancing the anti-loosening effect. During chewing, the spring force of the locking rod 20 continues to maintain the squeezing state, forming a dynamic anti-loosening protection.

[0064] Working principle: The base 1 is connected to the base plate 2 by fixing bolts 3. The lower end of the fixing bolts 3 is flush with the lower surface of the base plate 2 to avoid irritating the tissue. The base 1 and the base plate 2 are anchored to the alveolar bone by mounting bolts 4 to form a support platform. The positioning groove 11 of the base 1 engages with the bottom of the implant 9 to limit its vertical displacement. The threaded hole 6 at the upper end of the limiting seat 5 of the base plate 2 is in contact with the lower surface of the implant 9 to help fix its horizontal position. The clearance hole 10 inside the implant 9 provides a passage for the locking bolt 14. The support ring 7 is installed on the side of the base 1 and is pressed against the base plate 2 by the bottom spring. The inner side of the limiting frame 8 above it is attached to the limiting seat 5 and the outer side is attached to the base 1, forming a double guide. The upper end of the limiting frame 8 is engaged with the slot 12 of the implant 9 to constrain the circumferential direction. Rotation prevents chewing forces from causing angular deviation. The locking bolt 14 is concentrically threaded to the threaded hole 6 and passes through the clearance hole 10 to rigidly connect the implant 9 to the base plate 2, ensuring the vertical axis installation accuracy and avoiding initial angular deviation. The upper end of the locking bolt 14 is connected to the post 16 and the lower end is attached to the upper surface of the implant 9 to distribute occlusal stress. The frustum-shaped design of the upper end of the post 16 is hidden inside the crown to avoid metal exposure. At the same time, the load is evenly transmitted through end face contact to reduce thread fatigue. The inner limit hole 13 of the clearance hole 10 of the implant 9 is engaged with the outer end of the inner limit rod 17 of the locking bolt 14 to prevent the bolt from rotating. The limit rod 17 is slidably connected to the slide rod 19 through the slide groove 18. The spring between the slide rod 19 and the slide groove 18 provides continuous restoring force.

[0065] The upper end of the locking rod 20 of the docking post 16 is truncated at the lower end and fits against the bottom surface of the relief groove 15. It is connected to the docking post 16 by a spring. When the crown is installed, the crown presses down on the locking rod 20, and its truncated end face squeezes the inner end of the limiting rod 17, forcing the outer end of the limiting rod 17 to be inserted deeper into the limiting hole 13. During chewing, the spring force of the locking rod 20 maintains the compression state, forming a dynamic anti-loosening protection. The bridge achieves three-dimensional limiting through "positioning groove 11 + limiting frame 8" and uses a three-level anti-loosening system of "threaded connection locking bolt 14 - threaded hole 6 + mechanical locking limiting rod 17 - limiting hole 13 + dynamic compression locking rod 20 - limiting rod 17". Combined with the continuous elastic force of the spring assembly support ring 7, slide rod 19 and locking rod 20, it solves the problems of implant angle displacement and bolt loosening. At the same time, the adhesive-free "screw + locking" design facilitates later maintenance, and the concealed design of the docking post 16 improves aesthetics, achieving a unity of function and clinical needs.

[0066] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are merely specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the protection scope of the present invention.
