The implant 2 is embedded in an alveolar bone and comprises an implant base 22 and a sleeve body assembling part 23 extending from the proximal end surface of the implant base 22 to the proximal end.

The split sleeve 3 is slidably sleeved on the outer wall surface of the sleeve body assembling part 23, and the split sleeve 3 and the base platform 1 are relatively fixedly arranged.

Therefore, the split sleeve 3 connected with the base station 1 is arranged on the outer wall of the near end of the implant 2, so that the problem of inconvenience in scraping and treating peri-implant inflammation in clinic is solved. Once inflammation is discovered, the abutment 1 is taken out, and the split sleeve 3 which is covered with the mycoderm can be pulled out along the belt, so that on one hand, the space occupied by the split sleeve 3 around the implant 2 can be scraped without turning over a valve and cutting bones; on the other hand, the implant 2 does not need to be cleaned, the brand-new split sleeve 3 or the base station 1 with the split sleeve 3 can be directly replaced, the surface of a product is prevented from being scraped and washed incompletely, and the probability of recurrent inflammation is reduced.

Specifically, in this embodiment, coupling assembling 11 includes along 1 distal end face of base station is in proper order by the cone angle that sets up from near to far down cone portion 111, the anti portion 112 and the screw thread fastening portion 113 of revolving of regular hexagonal prism structure, implant 2 be equipped with above-mentioned structure assorted cavity structure 21, base station 1 with implant 2 passes through screw thread detachably fastening installation, and passes through anti relative position between them of revolving 112.

Of course, the structure of the connecting component 11 is not limited thereto, and in other embodiments, the anti-rotation portion 112 of the abutment 1 may be an anti-rotation structure such as a regular quadrangular prism or a regular octagonal prism, or may be a connecting component structure of other clinically common oral medical abutments.

The outer wall of the implant base 22 is provided with threads, and in different embodiments, the thread specifications can be adjusted according to different types and sizes of the implant 2, so as to firmly connect the implant base 221 with the alveolar bone and increase the contact area.

The outer wall of the sleeve body assembling part 23 is a smooth surface, so that the split sleeve 3 sleeved on the sleeve body assembling part can be taken out and replaced without resistance.

Further, as shown in fig. 2, in the present embodiment, the sleeve body assembling portion 23 has a cylindrical structure, and the shape of the hollow structure inside the split sleeve 3 matches the structure of the sleeve body assembling portion 23.

Of course, the structure of the sleeve body assembling portion 23 is not limited thereto, and in other embodiments, the sleeve body assembling portion 23 may also be designed to be a truncated cone structure with an upward conical angle, and the shape of the hollow structure inside the split sleeve 3 matches the structure of the sleeve body assembling portion 23, or other similar structures, as long as the split sleeve 3 can be sleeved or taken out relative to the sleeve body assembling portion 23 without resistance.

Furthermore, as shown in fig. 3, the sheath body assembling portion 23 is retracted inward relative to the implant base 22, and a retraction platform 24 is formed on the proximal end surface of the implant base 22, and the distal end surface of the split sheath 3 is flush with and abuts against the retraction platform 24. By providing the retraction platform 24, the implant base 22 can support and limit the split sleeve 3, so as to prevent the split sleeve 3 from loosening relative to the abutment 1 in long-term use due to the connection with the abutment 1. In addition, the split sleeve 3 is tightly abutted with the retraction platform 24, so that gaps at the intersection of the split sleeve and the retraction platform can be reduced, and an area for breeding bacteria is avoided.

A fixing portion 31 is formed on a proximal end surface of the split sleeve 3, and the abutment 1 is provided with a fixing connection portion 12 connected to the fixing portion 31.

The split sleeve 3 is made of biomedical metal or high polymer material.

Specifically, in the present embodiment, the material of the separate sleeve 3 is titanium alloy, in other embodiments, the separate sleeve 3 may also be made of medical metal or polymer material with good biocompatibility, such as zirconium oxide, titanium, 316LSS, polyetheretherketone, polymethylmethacrylate, and related composite materials thereof, wherein the composite material may be a multilayer composite material of titanium alloy and polyetheretherketone.

In this embodiment, the abutment 1 is a permanent abutment, the dental implant system further includes a cover screw and a healing abutment, the cover screw and the connection assembly structure of the healing abutment are similar to the connection assembly 11, the cover screw and the healing abutment include the fixing connection portion 12 or the split sleeve 3 integrally formed. In other embodiments, the abutment 1 can also cover the function of a screw and/or a healing abutment according to the difference of the proximal structure or model of the abutment 1.

The procedure for installing and replacing the dental implant system in this embodiment will be described in detail below:

in the installation process, a ball drill, a guide drill, a forming drill and the like are sequentially used for forming an alveolar socket with a required structure on an alveolar bone, the implant 2 is installed in the alveolar socket, a cover screw with the split sleeve 3 is installed, soft tissues are sutured, and a section of operation is completed. After the bone integration of the implant 2 is completed, the soft tissue is incised, the covering screw is taken out, the healing abutment with the split sleeve 3 is installed, and the two-stage operation is completed. After the soft tissue is healed, the healing base platform is replaced into the base platform 1 with the split sleeve 3, and a dental crown is installed.

After inflammation is discovered, in the replacement process, the dental crown and the abutment 1 are taken down, the abutment is taken out, and the split sleeve 3 which is covered with the mycoderm can be pulled out along the belt, so that the originally occupied space of the gum penetrating lantern ring 2 is exposed, and the original occupied space of the split sleeve 3 around the implant can be scraped without turning over a valve and cutting bones. After cleaning, the new split sleeve 3 is replaced and the abutment 1 and the dental crown are installed again.

In other embodiments, when the abutment 1 can cover the functions of the covering screw and/or the healing abutment at the same time, or according to different actual clinical surgery situations, one step of surgery and/or mounting the healing abutment can be skipped to directly perform surgical mounting of the abutment 1.

In conclusion, the split sleeve connected with the abutment is arranged on the outer wall of the proximal end of the implant, so that the problem of inconvenience in scraping and treating peri-implant inflammation in clinic is solved. Once inflammation is discovered, the abutment can be taken out, and the split sleeve which is fully covered with the mycoderm can be pulled out along the belt, so that on one hand, the space occupied by the original split sleeve around the implant can be scraped without turning over the valve and cutting the bone; on the other hand, the planting is not required to be cleaned, a brand-new split sleeve or a base station with the split sleeve can be directly replaced, the surface of the product is prevented from being scraped and washed incompletely, and the probability of recurrent inflammation is reduced.
