Description

Technical Field

[0001] This utility model relates to the field of oral implant technology, and in particular to a positionable oral implant healing abutment and a matching screwdriver. Background Technology

[0002] In the first stage of dental implant surgery, factors such as insufficient initial implant stability, poor oral hygiene, or smoking habits often necessitate embedding the healing abutment below the gum line. After a 3-6 month healing period, during the second-stage implant surgery, CBCT or panoramic radiographs are taken, and the surgeon's experience is used to locate the healing abutment within the patient's mouth. The gum is then incised to expose the abutment, and a suitable healing cap is placed over the exposed gum, allowing for subsequent implant restoration. The process of locating and incising the gum to expose the healing abutment is often slow and time-consuming, potentially leading to unnecessary incisions at the wrong site, increasing the risk of bleeding and infection. Utility Model Content

[0030] The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0031] Implementation Case 1:

[0032] Please see Figure 1-4 A positionable oral implant healing abutment includes an abutment body 1 and a rubber column 2. An installation hole 4 is provided at the center of the upper end face of the abutment body 1. A connecting groove 5 is provided below the installation hole 4 of the abutment body 1. The connecting groove 5 communicates with the installation hole 4. The rubber column 2 includes a connecting section 6 and a protruding section 7. The connecting section 6 of the rubber column 2 is installed in the connecting groove 5.

[0033] The rubber post 2 is connected to the abutment body 1 via the connecting groove 5 to prevent the rubber post 2 from becoming loose. During the first-stage implant surgery, the rubber post 2 can be trimmed according to the gingival height to make it flush with the gingiva, so that the occlusal collision during implant healing will not affect the integration of the implant with the alveolar bone. By setting the rubber post 2 on the abutment body 1, the rubber post 2 can be used to position the implant during the second-stage implant surgery, which greatly reduces the clinical operation time and can avoid incorrect incisions and reduce the chance of bleeding and infection.

[0034] By providing a mounting hole 4 at the center of the upper end face of the base body 1, it is easy to install and remove the base body 1 using a screwdriver.

[0035] Furthermore, the connecting groove 5 is located directly below the center of the mounting hole 4.

[0036] Furthermore, the connecting groove 5 has an internal thread structure, and the connecting section 6 of the rubber column 2 has an external thread structure. The external thread structure of the connecting section 6 matches the internal thread structure of the connecting groove 5.

[0037] The internal thread structure of the connecting groove 5 and the external thread structure of the connecting section 6 of the rubber column 2 make it easy to install the rubber column 2 onto the base body 1.

[0038] Furthermore, the mounting hole 4 is a hexagonal hole, and the diameter of the rubber post 2 is 1 mm. By setting the diameter of the rubber post 2 to 1 mm, the impact on the integration of the implant and alveolar bone due to occlusal collision is greatly reduced.

[0039] Furthermore, the rubber pillar 2 is a solid structure; the outer surface of the rubber pillar 2 is a smooth surface. By adopting a solid and smooth structure for the rubber pillar 2, similar to a transgingival implant healing abutment, the risk of infection is reduced during implant healing.

[0040] Furthermore, the bottom of the base body 1 is provided with a connecting part 8, which is used to connect the implant.

[0041] The present invention is equipped with a matching screwdriver 3 suitable for the healing base, which can accommodate the rubber post 2 without affecting the tightening of the healing base.

[0042] Implementation Case 2:

[0043] Please see Figure 5-6 A screwdriver 3 for installing a positionable dental implant healing abutment includes a handle 9 and a shaft 10. One end of the shaft 10 is connected to the handle 9, and the other end of the shaft 10 has a cutting edge 11. The cutting edge 11 has a groove 12 inside, the diameter of which is larger than the diameter of the rubber post 2. The outside of the cutting edge 11 mates with the mounting hole 4.

[0044] By providing a groove 12 inside the blade 11 of the matching screwdriver 3, the diameter of the groove 12 being larger than the diameter of the rubber column 2, the groove 12 can accommodate the rubber column 2. The outside of the blade 11 matches the mounting hole 4 on the top of the base body 1, making it convenient to install and remove the base body 1 using the matching screwdriver 3.

[0045] Furthermore, the outer surface of the blade 11 is a hexagonal structure corresponding to the mounting hole 4; the depth of the groove 12 is greater than the length of the protrusion 7.

[0046] Furthermore, the diameter of the groove 12 is 1.2 mm. The inner diameter of the groove 12 is slightly larger than the outer diameter of the rubber column 2, facilitating the tightening or disassembly of the healing base.

[0047] Regardless of the brand of the implantation system, this type of healing abutment can be made to match the original implant without changing the structure of the healing abutment to match the implant. It only requires embedding a rubber column 2 inside the healing abutment and changing the size of its screwdriver 11.

[0048] The main functions of this utility model are:

[0049] This invention features a rubber post that connects to the abutment body via a connecting groove, preventing the post from becoming loose. During the initial implant surgery, the rubber post can be trimmed to be flush with the gingiva, preventing impact on implant-alveolar bone integration due to occlusal collisions during healing. By incorporating the rubber post into the abutment body, it can be used to position the implant during the second-stage surgery, significantly reducing clinical operation time and avoiding incorrect incisions, bleeding, and infection. The connecting groove has an internal thread structure, while the connecting section of the rubber post has an external thread structure. The external thread structure of the connecting section matches the internal thread structure of the connecting groove, facilitating the installation of the rubber post onto the abutment body. A groove with a diameter larger than the rubber post's diameter is provided inside the blade of the accompanying screwdriver, allowing the groove to accommodate the rubber post. The external blade of the screwdriver mates with the mounting hole on the top of the abutment body, facilitating the installation and removal of the abutment body using the included screwdriver.
