As shown in figure 1, the utility model provides a substitute for an implant, comprising a main body 11 for placing on an oral cavity model to substitute the implant and a fastener 12 connected with the main body 11 to lock the main body 11 on the oral cavity model, wherein the side wall of the main body 11 near the bottom end of the main body 11 is provided with an anti-rotation surface 111 extending to the bottom end of the main body 11, one side of the main body 11 back to the anti-rotation surface 111 is concavely provided with at least one anti-channeling groove 112, the anti-channeling groove 112 is used for being matched and clamped with the oral cavity model in the traditional mold taking process, so that the main body 11 is axially limited on the oral cavity model, thereby when the substitute for an implant provided by the embodiment is used for 3D intraoral scanning to manufacture the oral cavity model, the circumferential limitation is realized through the matching of the anti-rotation surface 111 and the oral cavity model, and the main body 11 is locked on the oral cavity model through the fastener 12, so that the substitute for an implant is suitable for 3D intraoral scanning, and because the existence of anti-channeling 112, the substitute of the implant that this embodiment provided is when being used for traditional impression taking preparation oral cavity model, through preventing channeling 112 and oral cavity model cooperation joint, can make main part 11 by the axial spacing on oral cavity model, thereby the spacing oral cavity model that makes the substitute of this implant and traditional impression taking preparation of cooperation anti-rotation surface 111's circumference can zonulae occludens, thereby the substitute of the implant that this embodiment provided is applicable to traditional impression taking equally, has reduced manufacturer's production input.

In some embodiments, the body 11 is generally cylindrical in shape to facilitate forming and positioning during processing.

In some embodiments, the anti-rotation surface 111 extends to the bottom end of the main body 11, so that on one hand, the main body 11 is conveniently inserted into a corresponding mounting groove or mounting hole on a 3D intraoral scanning oral cavity model, and on the other hand, when the anti-rotation surface 111 abuts against the oral cavity model made by 3D intraoral scanning or traditional mold extraction, the main body 11 can be circumferentially limited on the oral cavity model.

Referring to fig. 3, in some of the embodiments, the anti-channeling groove 112 includes a plane 1121 on the main body 11 and parallel to the axial line of the main body 11, and two abutting surfaces 1122 on opposite sides of the plane 1121, the abutting surfaces 1122 being perpendicular to the plane 1121. Thus, the recessed anti-channeling groove 112 does not interfere with the mounting of the surrogate implant on the 3D intraoral scan-made oral model. The small component surface structure of the anti-channeling groove 112 facilitates processing and facilitates detection of the size of the anti-channeling groove 112. When the implant substitute is used in a traditional molded oral cavity model, the poured model material is filled in the anti-channeling groove 112 through flowing before solidification, after solidification, due to the existence of the abutting surface 1122 perpendicular to the axial direction of the main body 11 in the anti-channeling groove 112, the axial channeling of the main body 11 in the oral cavity model is blocked, and due to the existence of the plane 1121 in the anti-channeling groove 112, the freedom degree of the main body 11 in circumferential rotation is limited, and a certain circumferential limiting effect is performed on the main body 11, so that the implant substitute is prevented from rotating relative to the oral cavity model.

In some embodiments, the plane 1121 is parallel to the rotation resisting surface 111, so that the anti-channeling groove 112 can be machined by using the rotation resisting surface 111 as a reference plane, or the previously machined anti-channeling groove 112 can be used as a reference plane of the rotation resisting surface 111.

In some embodiments, the anti-channeling grooves 112 are two, and two anti-channeling grooves 112 are distributed on the main body 11 along the general axial direction of the main body 11 to improve the anti-axial-channeling effect of the anti-channeling grooves 112 on the implant substitute.

As shown in fig. 2 and 3, in some embodiments, the body 11 has a connecting hole 113 at an end corresponding to the fastening element 12, and the fastening element 12 includes a head 121 and a connecting portion 122 disposed on the head 121 for cooperating with the connecting hole 113 on the body 1, so as to clamp the dental model through an end surface of the head 121 opposite to the body 11 when the fastening element 12 is connected to the body 11, so that the implant substitute is locked to the dental model. Specifically, when the substitute of the implant is used for scanning in the 3D mouth, the main body 11 is inserted into the corresponding mounting groove or mounting hole of the oral cavity model made by scanning in the 3D mouth, and then the connecting portion 122 of the fastener 12 is inserted into the connecting hole 113 from the other end of the mounting groove or mounting hole and is connected with the connecting hole 113 in a matching manner, so that the main body 11 and the fastener 12 are clamped and fixed on the oral cavity model, and the matching installation of the substitute of the implant and the oral cavity model is completed.
