[0033] Please refer to the following: Figures 1 to 6The present invention provides a retaining abutment assembly. The retaining abutment assembly includes: an abutment 1, the abutment 1 having a boss 11 for being inserted into the implant cavity in a predetermined direction F; the outer surface of the boss 11 is provided with ribs 111 for being inserted into the implant cavity and for contacting the inner wall of the implant cavity.
[0034] Thus, the abutment 1 has a boss 11, which can be inserted into the cavity of the implant in a predetermined direction F; the outer surface of the boss 11 has a rib 111, which can be inserted into the cavity of the implant and can contact the inner wall of the cavity. When the rib 111 contacts the inner wall of the cavity, it can increase the friction and reduce the rotation of the boss 11 in the cavity; or when the inner wall of the cavity contacts the rib 111, it can directly prevent the boss 11 from rotating in the cavity.
[0035] In one embodiment, the boss 11 has an axis of symmetry, the direction of which is parallel to a predetermined direction F.
[0036] Further, please refer to Figures 1 to 6 In one specific embodiment of the retaining base assembly provided by this utility model, the protruding rib 111 extends along a predetermined direction F. Thus, the stress on the protruding rib 111 can be distributed along the predetermined direction F onto the boss 11.
[0037] Further, please refer to Figures 1 to 6 As a specific embodiment of the retaining base assembly provided by this utility model, the front edge of the protruding rib 111 has a chamfer 1111 in the predetermined direction F. In this way, the chamfer 1111 facilitates the insertion of the protruding rib 111 into the recessed cavity.
[0038] Further, please refer to Figures 1 to 6 As a specific embodiment of the fixed base assembly provided by this utility model, the chamfer 1111 is: a plane or an arc surface.
[0039] Further, please refer to Figures 1 to 6 As a specific embodiment of the retaining base assembly provided by this utility model, the intersection of the rib 111 and the boss 11 has a milling groove 112 formed by milling. In this way, machining the milling groove 112 can remove the burrs present at the intersection of the rib 111 and the boss 11; in addition, the milling groove 112 can also provide deformation space for the deformation of the rib 111.
[0040] Further, please refer to Figures 1 to 6 As a specific embodiment of the fixed base assembly provided by this utility model, the two side walls of the milling groove 112 are distributed as planes or arc surfaces.
[0041] Further, please refer to Figures 1 to 6As a specific embodiment of the retaining base assembly provided by this utility model, the milling groove 112 extends along a predetermined direction F.
[0042] Further, please refer to Figures 1 to 6 In one specific embodiment of the retaining base assembly provided by this utility model, the number of protruding ribs 111 is multiple. Thus, multiple protruding ribs 111 can increase the frictional force.
[0043] Further, please refer to Figures 1 to 6 In one specific embodiment of the retention abutment assembly provided by this utility model, multiple ribs 111 are arranged around the boss 11. In this way, the multiple ribs 111 prevent the boss 11 from rotating within the cavity of the implant.
[0044] Further, please refer to Figures 1 to 6 In one specific embodiment of the retention abutment assembly provided by this utility model, a groove 113 is formed between any two adjacent protrusions 111. In this way, an object on the inner wall of the implant cavity can be stuck in the groove 113 to prevent the protrusion 11 from rotating; in addition, the groove 113 can also provide deformation space for the protrusion 111 to deform.
[0045] Please see Figures 1 to 6 This embodiment also discloses a dental implant system, including: an implant with a cavity and a retention abutment assembly; a positioning groove extending in a predetermined direction F is provided on the inner wall of the cavity; a boss 11 is inserted into the cavity, and a rib 111 is inserted into the positioning groove. Thus, due to the use of the aforementioned retention abutment assembly, the abutment 1 has a boss 11, which can be inserted into the cavity of the implant in the predetermined direction F; the outer surface of the boss 11 has a rib 111, which can be inserted into the cavity of the implant and can contact the inner wall of the cavity; when the rib 111 contacts the inner wall of the cavity, it can increase friction and reduce the rotation of the boss 11 in the cavity; or when the inner wall of the cavity contacts the rib 111, it can directly prevent the boss 11 from rotating in the cavity; the positioning groove extends in the predetermined direction F, and the rib 111, after being inserted into the positioning groove, can prevent the boss 11 from rotating in the cavity.
[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
