Description

Technical Field

[0001] The utility model belongs to the field of dental medical equipment, and in particular relates to a multi-feature implant scanning body. Background Art

[0002] The production of personalized implant abutments is widely used in clinical implant restorations because of its advantages such as adjustable angle and direction of the implant abutments and adaptability to the gingival morphology. Among them, the scanning rod is a crucial component in the process of making personalized implant abutments. It is mainly used in the process of scanning the position and direction of the oral implants by the model scanner or intraoral scanner. By scanning the scanning rod, the position and direction data of the oral implants can be obtained, and the surface can be matched with the model in the implant database in the design software, that is, the implant information can be obtained, thereby completing personalized restoration.

[0003] A dental implant scanning body disclosed in patent CN219021628U includes: a base and a screw for fixing on the implant; the base has a through hole, and the screw is inserted into the through hole; in the extension direction of the through hole, the base has an implant part for being clamped in the gums and a marking part with a first mark on the outer surface in sequence; the number of the first marks is multiple, and the multiple first marking rings are arranged on the outside of the through hole and are arranged in sequence.

[0004] In the above scheme, although multiple marks are set on the scanning body, so that the user can observe or scan the first mark from different angles outside the through hole when tightening the screw or observing the scanning body, the actual situation is that the same image may be observed or scanned at multiple angles. If these images with the same visual effect at different angles cannot be distinguished, this will greatly hinder the recognition of the scanning body, thereby affecting the repair accuracy.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the utility model and the accompanying drawings to further describe the technical solution of the utility model, but the utility model is not limited to these embodiments.

[0026] like Figure 1-Figure 4 As shown, a multi-feature implant scanning body comprises a cylindrical body 1 and a bolt rod 2. An axial bolt rod through hole is provided in the cylindrical body 1, and the bolt rod 2 is slidably arranged in the bolt rod through hole. A height feature surface 11 is provided on one end face of the cylindrical body 1, and a plurality of different angular feature structures are provided on the surface of the cylindrical body 1 close to the height feature surface 11. An angle fixing portion 12 is provided at the other end of the cylindrical body 1, and a threaded portion of the bolt rod 2 extends from the angle fixing portion 12.

[0027] That is, a height characteristic surface 11 is established on the end face of a scanning body that is bolted and fixed by a bolt rod 2 and an angle fixing part 12 to obtain the height data of the scanning body. At the same time, a plurality of angle characteristic structures with different shapes are arranged at the same end of the height characteristic surface 11, so that the projection images of the scanning body from various angles will not be the same, thereby improving the scanner's recognition of the scanning body in various directions and collecting data more accurately and completely.

[0028] In this embodiment, the angle characteristic structure includes a characteristic notch 13 and a characteristic groove 14 . The characteristic groove 14 is provided on the height characteristic surface 11 , and the characteristic notch 13 is axially provided along the side arc surface of the cylindrical body 1 starting from the height characteristic surface 11 .

[0029] The characteristic notch 13 is formed by axially cutting off a section of arc surface from the height characteristic surface 11, so that a plurality of plane notches are formed on the arc surface of the cylindrical body 1, so as to improve the resolution characteristics of the scanning body.

[0030] The characteristic groove 14 is provided on the same end surface as the height characteristic surface 11 and is used as a mark in the axial direction so that the scanner can further verify the rotation angle obtained from the characteristic notch 13 .

[0031] Preferably, the lengths of the characteristic notches 13 extending from the height characteristic surface 11 are different, and each characteristic notch 13 has a corresponding characteristic groove 14 .

[0032] By changing the chip length of the notch when opening the characteristic notch 13, as the distinguishing point of each characteristic notch 13, the characteristic notches 13 appear in step shapes of different heights on the projection image in the horizontal direction.

[0033] In order to more intuitively display the rotation angle of the cylindrical body 1, each characteristic groove 14 is arranged one by one on the height characteristic surface 11 corresponding to each characteristic notch 13, so that the installation status of the scanning body can be identified by naked eye observation, avoiding the scanning body at different positions rotating to the same angle and then presenting the same image on the projection screen, which increases the recognition difficulty of the scanner.

[0034] Preferably, the opening depths of the characteristic notches 13 are different, and each characteristic notch 13 has a corresponding characteristic groove 14 .

[0035] By changing the chip depth of the notch when opening the characteristic notch 13, the chip surface shows rectangular planes of different sizes, forming a non-equilateral polygon on the height characteristic surface 11 of the axial viewing angle, ensuring that the image during axial scanning can show the rotation angle of the cylindrical body 1.

[0036] In order to more intuitively display the rotation angle of the cylindrical body 1, each characteristic groove 14 is arranged one by one on the height characteristic surface 11 corresponding to each characteristic notch 13, so that the installation status of the scanning body can be identified by naked eye observation, avoiding the scanning body at different positions rotating to the same angle and then presenting the same image on the projection screen, which increases the recognition difficulty of the scanner.

[0037] Preferably, the characteristic groove 14 is arranged on the perpendicular midline of the cross section of the characteristic notch 13 so as to be easier to observe when the scanning body is installed, and each characteristic groove 14 has a different notch shape.

[0038] The angle fixing portion 12 is usually configured as an equilateral hexagon, which is first assembled with the hexagonal groove of the implant before the bolt rod 2 is locked, so as to fix the angle of the columnar body 1 to prevent the columnar body 1 from rotating when the bolt rod 2 is locked.

[0039] The characteristic notch 13 is set as a concave structure because the convex part of the convex structure is higher than the height characteristic surface 11, and the convex part is likely to cause errors in height data when the scanner scans horizontally.

[0040] In this embodiment, a guide surface 15 is provided on the outer arc surface of the cylindrical body 1 , and the guide surfaces 15 are gradually retracted inward toward the angle fixing portion 12 to form a plurality of annular steps.

[0041] An annular step cooperating with the columnar body 1 is also provided in the implant. Since the columnar body 1 is fixed by bolting and pulling with the bolt rod 2, it is necessary to avoid a single part of the columnar body 1 to bear the axial pressure. Therefore, the pressure is dispersed on the step surface by utilizing the cooperation of the annular step, so that the columnar body 1 is more stable after being locked.

[0042] In this embodiment, the bolt rod through hole includes a limit channel 16 and a pull rod channel 17, and a tapered portion is provided between the limit channel 16 and the pull rod channel 17, and the tapered portion connects the limit channel 16 with a large aperture and the pull rod channel 17 with a small aperture.

[0043] On the one hand, the tapered portion can guide the bolt rod 2 to accurately extend into the internal thread of the implant, and on the other hand, when the bolt rod 2 is locked, the mutual abutment with the tapered portion can provide additional anti-slip protection.

[0044] In this embodiment, the bolt rod 2 includes a connected sliding rod portion 21 and a pulling rod portion 22. The sliding rod portion 21 slides in cooperation with the limiting channel 16, and the pulling rod portion 22 extends from the angle fixing portion 12 through the pulling rod channel 17. The threaded portion is arranged at one end of the pulling rod portion 22 extending outside the angle fixing portion 12.

[0045] The cooperation between the slide rod portion 21 and the limiting channel 16 is used as a limiting guide when the bolt rod 2 moves axially, and the auxiliary bolt rod 2 does not shake when being screwed. A gap is left between the pull rod channel 17 and the pull rod portion 22, and the pull rod channel 17 is left with a gap under the guidance of the limiting channel 16 to reduce friction.

[0046] In this embodiment, an inclined transition surface 23 is provided at the connection between the sliding rod portion 21 and the pulling rod portion 22. The transition surface 23 cooperates with and abuts against the tapered portion, so that the bolt rod 2 can be fixed in the axial position under pressure, and the reaction force of the tapered portion on the transition surface 23 can make the connection between the bolt rod 2 and the implant more stable.

[0047] Preferably, a receiving groove 18 having a diameter larger than that of the pull rod passage 17 is provided in the angle fixing portion 12 , and the threaded portion can be retracted into the receiving groove 18 .

[0048] Usually, when installing the scanning body, the angle fixing part 12 is first inserted into the fixing groove of the implant to limit its circumferential rotation. Therefore, the receiving groove 18 is provided to provide a retreat space for the threaded part so that the threaded part does not block the installation of the angle fixing part 12.

[0049] The inner diameter of the accommodating groove 18 is equal to that of the threaded portion and larger than the pull rod channel 17, so that the retracted threaded portion abuts against the opening of the pull rod channel 17. In addition, the cooperation between the tapered portion and the transition surface 23 can restrict the bolt rod 2 in the pull rod channel 17 and prevent it from falling due to shaking.

[0050] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
