Description

Technical Field

[0001] This utility model mainly relates to the field of dental prosthesis technology, specifically a highly stable dental prosthesis connection structure that integrates with alveolar bone. Background Technology

[0002] Dental prostheses, also known as dental implants, do not involve planting natural teeth. Instead, they are created through a medical procedure where holes are drilled in the alveolar bone in the area of ​​the missing tooth, and a pure titanium metal implant, which is highly biocompatible, is surgically inserted into the alveolar bone. After several months, once the implant has integrated with the alveolar bone, the prosthesis is fixed in place.

[0003] Current technology, to facilitate future denture replacement, separates the implant and crown, connecting them detachably via a connector. This connector typically uses threaded, adhesive, or magnetic connections. However, threaded connections are prone to scratching adjacent teeth and are difficult to install, while adhesive and magnetic connections can lead to instability in the implant-crown connection. Therefore, a denture connection structure that balances ease of installation and removal with structural stability is needed. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable denture connection structure that integrates with alveolar bone, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-stability denture connection structure that integrates alveolar bone, comprising an implant that is threadedly connected to the alveolar bone, a crown that is detachably mounted on the implant, an installation groove on the implant, snap-fit ​​grooves on both sides of the installation groove, and a connecting component fixedly mounted at the bottom of the crown, the connecting component fitting into the installation groove;

[0006] The connecting component has movable grooves on both sides, and a spring is fixedly installed in the movable groove. The other end of the spring is fixedly connected to a latch. The latch fits into the latching groove. The connecting component forms a central cavity. A guide tube communicating with the outside is installed on the central cavity. A pull plate is movably installed in the central cavity along the height direction. A steel wire is connected to the pull plate and is fixedly connected to the latch.

[0007] Preferably, auxiliary insertion ports are formed on both sides of the top of the mounting groove, perpendicular to the snap-fit ​​groove. A limiting groove is formed in the horizontal direction inside the auxiliary insertion port. Limiting strips that fit into the auxiliary insertion ports are formed on both sides of the connecting component. Elastic retaining rings that fit into the limiting grooves are formed on the limiting strips.

[0008] Furthermore, the top edges of the mounting slot and auxiliary socket are rounded.

[0009] Preferably, the upper and lower sides of the movable groove narrow towards each other, while the upper and lower sides of the inward end of the latch extend in opposite directions to prevent the latch from disengaging from the movable groove.

[0010] Furthermore, the outward end of the latch is inserted into the latching groove, and the longitudinal section of the outward end is a right-angled trapezoid with its hypotenuse facing down and its right-angled side facing up.

[0011] Preferably, a sealing gasket is provided at the connection position between the implant and the crown, and the sealing gasket surrounds the mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a highly stable denture connection structure that integrates alveolar bone. Through the axial insertion and engagement of the implant mounting slot and the crown connection component, combined with the automatic engagement and locking of the spring-driven clasp and the locking groove on the side wall, vertical pressing installation is achieved, avoiding the risk of rotational scraping of threaded connections. The fitting of the limiting insert and the auxiliary insert forms a double anti-rotation constraint, improving lateral stability. The elastic retaining ring and the limiting groove also cooperate to further improve axial stability. The guide tube is pulled back synchronously by the steel wire through the central cavity pull plate, facilitating precise disassembly of the structure. The surrounding sealing gasket and the anti-detachment clasp structure work together to ensure the sealing of the connection position and the integrity of the components, thus maintaining the rigid and stable connection between the implant and the crown while taking into account the ease of disassembly and assembly.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, a high-stability denture connection structure with alveolar bone integration includes an implant 1 that is threadedly connected to the alveolar bone, a crown 2 that is detachably mounted on the implant 1, an installation groove 11 that is opened on the implant 1, and a snap-fit ​​groove 12 that is provided on both sides of the installation groove 11. A connecting component 3 is fixedly mounted on the bottom of the crown 2, and the connecting component 3 fits into the installation groove 11.

[0025] The connecting component 3 has movable grooves 31 on both sides of its side walls. A spring 32 is fixedly installed in the movable groove 31. The other end of the spring 32 is fixedly connected to a latch 33. The latch 33 fits into the latching groove 12. The connecting component 3 forms a central cavity 35 inside. A guide needle tube 21 communicating with the outside is provided on the central cavity 35. A pull plate 36 is movably installed in the central cavity 35 along the height direction. A steel wire 34 is connected to the pull plate 36. The steel wire 34 is connected and fixed to the latch 33.

[0026] The guide tube 21 passes through the crown 2 and the connecting component 3 from top to bottom to enter the central cavity 35. Preferably, a silicone sealing plug is provided at the top inlet position of the guide tube 21 to prevent saliva leakage during daily use. When disassembly and replacement are required, the silicone sealing plug is removed from the outside, and then the pull plate 36 is pressed down with a pusher under the guidance of the guide tube 21. A groove is formed on the pull plate 36 at the position corresponding to the guide tube 21 to facilitate the external pusher to apply sufficient force to press down the pull plate 36.

[0027] Auxiliary insertion ports 13 are formed on both sides of the top of the mounting groove 11, perpendicular to the snap-fit ​​groove 12. A limiting groove 14 is formed horizontally within each auxiliary insertion port 13. Limiting strips 37, which fit into the auxiliary insertion ports 13, are formed on both sides of the connecting component 3. Elastic retaining rings 38, which fit into the limiting grooves 14, are formed on the limiting strips 37. The interaction between the limiting strips 37 and the auxiliary insertion ports 13 guides the connecting component 3 to insert accurately and provides anti-rotation constraint, improving lateral stability. The elastic retaining rings 38, in turn, cooperate with the limiting grooves 14 to provide anti-insertion and anti-removal constraint, improving axial stability.

[0028] The top edges of the mounting groove 11 and the auxiliary socket 13 are rounded, which guides the insertion of the connecting component 3 and reduces the accuracy requirements of the insertion position.

[0029] The upper and lower sides of the movable groove 31 narrow towards each other, while the upper and lower sides of the inner end of the latch 33 extend in the opposite direction to restrict the latch 33 from sliding outward and disengaging from the movable groove 31.

[0030] The outer end of the latch 33 is inserted into the latching groove 12, and the longitudinal section of the outer end is a right-angled trapezoid with its hypotenuse facing down and its right-angle side facing up. Thus, when the connecting component 3 is inserted, the latch 33 can be retracted inward with the cooperation of the rounded corner of the top edge of the mounting groove 11 and the hypotenuse of the latch 33. After the latch 33 is fixed, its right-angle side is pressed against the top of the latching groove 12 to prevent the connecting component 3 from being pulled out.

[0031] A sealing gasket 4 is provided at the connection position between the implant 1 and the crown 2. The sealing gasket 4 surrounds the mounting groove 11 and seals the inside of the mounting groove 11 to prevent saliva from seeping into the inside.

[0032] The implementation principle of this application embodiment is as follows: When installing this product, first, a hole is drilled in the human alveolar bone and the implant 1 is threaded in. A sealing gasket 4 is placed on the top of the implant 1. Then, the limiting insert 37 is aligned with the auxiliary insert 13 and inserted until the elastic retaining ring 38 enters the limiting groove 14. At the same time, the retaining tongue 33 also enters the retaining groove 12 for vertical pressing and automatic locking. When the crown 2 needs to be replaced later, the jack is inserted into the top of the guide tube 21. One hand uses a tool to press down the jack, and the jack presses down the pull plate 36, thereby pulling the wire 34 inward and further driving the retaining tongue 33 to move inward and disengage from the retaining groove 12. The other hand uses a tool to overcome the elasticity of the elastic retaining ring 38 and pulls the crown 2 directly upward. Then, the installation process is repeated to replace the new crown 2. While maintaining the rigid and stable connection between the implant and the crown, the ease of disassembly and assembly is also taken into account.

[0033] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
