Description

Technical Field

[0001] The utility model belongs to the field of oral medical devices, and particularly relates to an anti-fracture implant device. Background Technique

[0002] An implant-supported restoration consists of an implant and its superstructure. The implant, also known as an artificial tooth root, is made of artificial materials such as metals and ceramics and is surgically implanted into the jawbone in the toothless area. After a period of time, the artificial tooth root will undergo osseointegration with the surrounding bone tissue. Then, using this artificial tooth root as a support, a superstructure is connected to it through some special connecting devices. By connecting with the artificial tooth root, retention and support can be obtained from the artificial tooth root to repair the missing tooth.

[0003] However, in the prior art, since the implant needs to be in the body for a long time, such as when chewing hard foods or grinding teeth, the implant is subjected to axial forces for a long time. Stress concentration is likely to occur at the contact between the implant and the prosthetic abutment, leading to fracture. Moreover, continuous friction with the alveolar bone damages the implant. Therefore, it is necessary to provide a device that can effectively prevent implant damage and fracture. Summary of the Utility Model

[0004] To solve the above problems, the utility model designs an anti-fracture implant device. A buffer structure is provided. When chewing hard foods during use, the downward axial force received can be buffered by the spring below, reducing the friction between the implant and the alveolar bone. At the same time, a wrapped fixing ring is provided to disperse the stress at the originally stress-concentrated connection to the fixing block, reducing the risk of fracture caused by stress concentration.

[0005] To achieve the above effects, the utility model is realized through the following scheme: an anti-fracture implant device, specifically including: a housing, an implant, a buffer base, a fixing block, and a prosthetic abutment.

[0006] The housing is a hollow structure, and a buffer base is arranged inside the housing; the upper end of the buffer base is movably connected to the lower end of the implant, and the upper end of the implant is movably connected to the fixing block; the prosthetic abutment is threadedly connected inside the implant.

[0007] Grooves are respectively arranged at the connection between the buffer base and the implant, and the two grooves are cross-fitted and are in clearance fit; springs are arranged at both ends of the groove of the buffer base to connect the protruding parts of the implant.

[0008] Furthermore, annular grooves are respectively arranged at the connection between the buffer base and the implant, the two grooves are fitted, and a fixing ring is arranged at the groove to fix the buffer base and the implant.

[0009] Furthermore, the implant is rotatably connected to the fixing block via a connecting shaft; a fixing ring 2 is provided on the upper part of the implant, and an external thread is provided on the upper end of the fixing block, and the fixing block is fitted to the repair machine through the fixing ring and the fixing block 2 being threadedly connected;

[0010] The beneficial effects of the utility model are:

[0011] The utility model connects the implant with a buffer base, and the downward axial force received when chewing hard food during use can be buffered by the spring below, reducing the friction between the implant and the alveolar bone, providing a buffering effect when receiving the axial force, and reducing the force directly transmitted to the implant and the alveolar bone; the groove between the buffer base and the implant adopts a clearance fit, allowing a certain degree of displacement to adapt to the slight movement caused by the chewing force;

[0012] At the same time, a fixing block is set at the connection between the implant and the restoration base to disperse the stress at the connection where stress is originally concentrated to the fixing block, reducing the risk of fracture caused by stress concentration; the use of the fixing block enhances the stability of the upper structure of the implant, making the entire implant device more secure during chewing.

[0020] The utility model discloses an anti - fracture implant device, which includes a housing 1, an implant 3, a buffer base 2, a fixing block 7, and a repair abutment 8; the housing 1 is set to be hollow, and a buffer base 2 is arranged inside the housing 1; the upper end of the buffer base 2 is movably connected to the lower end of the implant 3, and the upper end of the implant 3 is movably connected to the fixing block 7; the repair abutment 8 is connected inside the implant 3; grooves are respectively arranged at the connection of the buffer base 2 and the implant 3, and the two grooves are cross - fitted, and the fitting method is clearance fit; springs 4 are arranged at both ends of the groove of the buffer base 2 to connect the protruding parts of the implant 3; through the spring buffer connection on the buffer base 2, the device can buffer internally when receiving a downward force, preventing the friction between the implant 3 and the alveolar bone; a fixing block is arranged at the connection of the implant and the repair abutment, so that the stress concentrated at the original connection is dispersed to the fixing block, effectively improving the stress problem of the implant.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] In this embodiment, grooves are arranged at the connection of the upper end of the buffer base 2 and the lower end of the implant 3; a fixing ring 1 5 is arranged at the groove to fix the buffer base 2 and the implant 3; threads are arranged inside the implant 3 to connect the repair abutment 8; the repair abutment 8 and the fixing block 7 are rotatably connected through a connecting shaft 9.

[0024] When in use, when the device receives a downward force during chewing, the spring 4 arranged below the buffer base 2 is stressed. Since the grooves at the upper end of the buffer base 2 and the lower end of the implant 3 are connected with clearance fit, the implant can move downward when receiving a large force, effectively buffering the downward force and preventing the friction between the implant 3 and the alveolar bone, solving the problem that the implant in the prior art is easily damaged by friction.

[0025] In this embodiment, the buffer base is provided with springs, which can provide a buffering effect when subjected to axial force, reducing the force directly transmitted to the implant and the alveolar bone; the groove between the buffer base and the implant adopts a clearance fit, allowing a certain degree of displacement to adapt to the minute movement caused by the chewing force; reducing the direct pressure of the implant on the alveolar bone, protecting the alveolar bone from damage, and contributing to maintaining oral health; the buffer base can be adjusted according to different types of implants and the oral conditions of patients, having good adaptability, reducing unnecessary movement and pressure of the implant, and improving the comfort of patients during use.

The lower end of the fixing block 7 is grooved, and a second fixing ring 6 is provided. Threads are provided at the upper end of the groove.

[0027] During use, after screwing the prosthetic abutment 8 into the internal thread of the implant 3, the second fixing ring is slid upward along the groove 6 at the lower end of the fixing block 7 and tightened at the thread at the upper end of the fixing block 7 to reach the position as Figure 4 shown, dispersing the force originally concentrated at the connection between the prosthetic abutment and the implant, improving the stress concentration problem at the connection between the prosthetic abutment and the implant, and thus solving the problem that implants are prone to fracture in the prior art.

[0028] In this embodiment, through the connection of the fixing block with the implant, the stress originally concentrated at the connection between the implant and the prosthetic abutment is dispersed, reducing the risk of fracture caused by stress concentration; the use of the fixing block enhances the stability of the upper structure of the implant, making the entire implant device more firm during chewing; through the intervention of the fixing block, the chewing force directly borne by the implant is reduced, thereby protecting the implant from damage; the design of the fixing block can be adjusted according to different types of implants and prosthetic abutments, providing flexibility in design; the use of the fixing block improves the patient's experience during use, reducing discomfort or pain caused by implant problems; the design of the fixing block is an important part of the anti-fracture implant device.
