As shown in fig. 1 and 2 and fig. 8, the implant 10 of the present embodiment is mated to a transfer bar 20. The implant 10 includes: implant 11 and abutment 12. The abutment 12 includes an abutment body 121 provided on the distal end of the implant 11, and a frustum portion 122 provided on the distal end of the abutment body 121. The implant 11 and the base 12 are integrally formed as a single component, and a positioning structure for positioning and matching with the transfer rod 20 is disposed on a side wall of the frustum portion 122.

With the solution of the present embodiment, the implant 10 is engaged with the transfer rod 20. The implant 10 includes: implant 11 and abutment 12. Base station 12 is including setting up in the base station 12 body on the top of implant 11 and setting up in frustum portion 122 on the top of base station 12 body, and wherein, implant 11 and base station 12 are an integrated into one piece's a part, can avoid having the fit-up gap in the junction of implant 11 and base station 12, has reduced assembly error. The side wall of the conical table portion 122 is provided with a positioning structure matched with the positioning of the transfer rod 20. The implant 11 is fixed on a mandible or a maxilla, the abutment 12 is used for connecting a dental crown to the implant 10, the frustum part 122 is in positioning fit with the transfer rod 20, the impression tray is used for recording the position information of the denture installing part when the frustum part 122 is in positioning fit with the transfer rod 20, the transfer rod 20 and the impression tray are taken down, and then the impression tray is used for making a mandible or maxilla model to make the dental crown. Since the positioning structure on the side wall of the frustum portion 122 is in positioning fit with the transfer rod 20, the transfer rod 20 can be positioned on the abutment 12, and more accurate position information of the denture attachment site can be provided. Therefore, the technical scheme of the embodiment effectively solves the problem that no positioning function exists between the base station and the transfer rod in the related art.

In this embodiment, an external thread is provided on an outer sidewall of the implant 11 for fixation with a mandible or a maxilla.

It should be noted that the plane of the bottom end of the abutment body 121 is a bone horizontal implant plane, and as shown in fig. 6, the transgingival height C above the bone horizontal implant plane is preferably in the range of 1mm to 4 mm.

As shown in fig. 1, the axis of the frustum portion 122 is disposed obliquely to the axis of the base body 121, and the acute angle b is formed between the axis of the frustum portion and the axis of the base body. Because the inferior maxilla or the maxilla of the human body is different and has a deviation, the implant 11 is fixed on the inferior maxilla or the maxilla, and the axis of the frustum part 122 is obliquely arranged relative to the axis of the abutment body 121, so that the deviation of the inferior maxilla or the maxilla of the human body can be corrected, and the false tooth can be more accurately and stably installed. The range of the inclination of the axis of the frustum portion 122 with respect to the axis of the base body 121 is preferably 20 ° to 35 °, specifically, 20 ° or 25 ° or 30 ° or 35 °. Further, in this embodiment, as shown in fig. 1, an acute included angle a formed between a plane where the top end of the frustum portion is located and a plane where the bottom end of the frustum portion is located can correct the deviation of the mandible or the maxilla of the human body, so that the denture can be more accurately and stably installed.

As shown in fig. 5, the side surface of the frustum portion 122 intersects thebase:Sub>A-base:Sub>A direction cutting plane to formbase:Sub>A left side intersection line andbase:Sub>A right side intersection line, and the length of the left side intersection line is greater than the length of the right side intersection line.

As shown in fig. 1 and 2, the positioning structure is a positioning groove 13, and the positioning groove 13 penetrates an end surface of a side wall of the frustum portion 122 in a bottom-to-top direction of the frustum portion 122.

Specifically, the positioning groove 13 is an elongated groove, and compared with a square groove, the elongated groove can increase the contact area when the frustum portion 122 is in positioning fit with the transfer rod 20, and can increase the stability when the frustum portion 122 is in positioning fit with the transfer rod 20.

Specifically, in the present embodiment, the transfer lever 20 is provided with a positioning rib 23 (see below) which is in positioning fit with the positioning groove 13.

As shown in fig. 1 to 4, the positioning structure is plural, and the plural positioning structures are arranged at intervals along the circumferential direction of the frustum portion 122, so that the stability and accuracy of positioning and matching the frustum portion 122 and the positioning ribs 23 on the transfer bar 20 can be increased. In this embodiment, the number of positioning structures is two. Of course, in the embodiment not shown in the drawings, the number of the positioning structures may be one, three, four or more.

As shown in fig. 1 to 4, the positioning structure is a plurality of positioning grooves 13, and orthogonal projections of two adjacent positioning grooves 13 on a plane where a top end of the frustum portion 122 is located are a first projection and a second projection, which respectively extend in a radial direction of the frustum portion 122 and intersect with an axis of the frustum portion 122. Thus, when the plurality of positioning ribs 23 on the transfer rod 20 move downwards along the axis of the frustum portion 122, the adjacent positioning ribs 23 are quickly positioned to the corresponding adjacent two positioning grooves 13, and the assembly efficiency is improved.

As shown in fig. 1 to 4, the first projection and the second projection form a right angle therebetween. The arrangement makes the stress of the two positioning structures uniform, so that the positioning fit of the conical part 122 and the transfer rod 20 is more stable, and the positioning fit of the conical part 122 and the transfer rod 20 is more accurate.

In an embodiment not shown in the figures, the first projection and the second projection form an obtuse included angle therebetween.

As shown in fig. 3 to 7, the implant 11 is provided with an operation sink 14, the abutment 12 is provided with an avoidance hole 15 communicating with the operation sink 14, and the avoidance hole 15 communicates with the outside of the implant 10, wherein the operation sink 14 is a cross-shaped groove. Thus, the implant tool can be smoothly inserted into the operation sink 14 from the relief hole 15 at the time of operation, and the implant tool is engaged with the cross recess to transmit torque so that the implant 11 is fixed to the mandible or the maxilla. And the cross groove can transmit larger torque, particularly in the range of 30N cm to 50N cm. Further, the depth W of the cross recess is preferably in the range of 3mm to 5mm, the recess width B1 is preferably in the range of 0.8mm to 1.2mm, the recess length B2 is preferably in the range of 2.1mm to 2.5mm, and the cross recess is preferably rounded.
