Description

Technical Field

[0001] This application relates to the field of dental implant technology in oral medicine, specifically to an implant bone healing abutment. Background Technology

[0002] The healing abutment, also known as a healing cap, healing screw, or gingival reshaping device, is screwed into the implant after it has been exposed in non-submerged or submerged implant surgery. It forms a transmucosa transition zone for the implant and guides the healing of the soft tissue and epithelial growth around the implant before the prosthesis is placed in place, forming the groove epithelium. In addition, the healing abutment extends through the mucosa into the oral cavity, preventing food debris and foreign body fragments from entering the abutment connection area. This is beneficial for soft tissue healing and the formation of a soft tissue seal around the implant neck. Therefore, the healing abutment is also called a transmucosa extension or transmucosa abutment.

[0003] If bone defects are found during implantation, bone powder needs to be placed. Bone powder helps bone formation around the implant and acts as a scaffold, guiding surrounding normal bone to grow into the bone powder. After using bone powder, the bone environment and conditions around the implant can be improved, allowing the implant to survive and last longer. However, before the bone powder fuses with the bone tissue around the implant, there is a problem of bone powder leaking out from between the healing abutment and soft tissue. Utility Model Content

[0004] Therefore, there is a need to provide a bone graft healing abutment to solve the problem in existing technologies where bone powder placed during implantation easily leaks out between the healing abutment and soft tissue.

[0005] To achieve the above objectives, the inventors provide a bone graft healing platform, comprising:

[0006] The main body includes a first end and a second end, the first end being used to connect with the implant and the second end being used to support the gingiva;

[0007] A cover plate is provided at the second end and protrudes radially outward from the second end along the body to form a gingival covering portion surrounding the second end.

[0008] In some embodiments, the cover plate is radially arranged from the center outwards as a connecting area and a covering area, the covering area being the gingival covering portion, and the connecting area being connected to the end face of the second end.

[0009] In some embodiments, the cover plate is an annular plate, which is the gingival covering portion. The annular plate is fitted onto the second end, and the inner ring of the annular plate is connected to the circumferential surface of the second end.

[0010] In some embodiments, the gingival covering portion is provided with a plurality of anti-adhesion holes.

[0011] In some embodiments, a plurality of anti-adhesion holes are arranged at equal intervals around the center of the cover plate.

[0012] In some embodiments, the first end is provided with external threads.

[0013] In some embodiments, the second end is cylindrical; or the diameter of the second end gradually increases in the direction away from the first end until it becomes frustum-shaped.

[0014] In some embodiments, the body further includes an intermediate segment located between the first end and the second end, the diameter of the intermediate segment being smaller than the diameter of the second end.

[0015] In some embodiments, the intermediate segment gradually increases in size towards the direction away from the first end until it becomes a frustum shape.

[0016] In some embodiments, it also includes:

[0017] The wrench groove passes sequentially through the center and the second end of the cover plate.

[0018] Unlike existing technologies, the bone graft healing abutment described in the above technical solution is used to guide the healing of soft tissue around the implant before the prosthesis is placed, guide and promote bone tissue growth around the implant, reduce the risk of bone resorption around the implant, provide support for the implant, and prevent the implant from shifting during the healing process. The main body of the bone graft healing abutment is connected to the implant at the first end and to a cover plate at the second end. The cover plate is located at the second end and protrudes radially outward from the second end, forming a gingival covering portion surrounding the second end. After the first end is connected to the implant, the gingival covering portion covers the gingiva, especially the gap between the gingiva and the second end, thereby preventing bone powder from leaking out of the gap and ensuring normal fusion of the bone powder with the surrounding bone tissue. This ensures bone formation around the implant and can be used when bone powder is placed in the soft tissue around the implant due to bone defects. Before normal bone grows into the bone powder, it prevents bone powder from leaking into the oral cavity from the gap between the gingiva and the abutment, ensuring normal fusion of the bone powder with the surrounding bone tissue and ensuring bone formation around the implant, forming a stable bone tissue structure.

[0048] The healing abutment, also known as a healing cap, healing screw, or gingival reshaping device, is screwed into the implant after it has been exposed in non-submerged or submerged implant surgery. It forms a transmucosa transition zone for the implant and guides the healing of the soft tissue and epithelial growth around the implant before the prosthesis is placed in place, forming the groove epithelium. In addition, the healing abutment extends through the mucosa into the oral cavity, preventing food debris and foreign body fragments from entering the abutment connection area. This is beneficial for soft tissue healing and the formation of a soft tissue seal around the implant neck. Therefore, the healing abutment is also called a transmucosa extension or transmucosa abutment.

[0049] If bone defects are found during implantation, bone powder needs to be placed. Bone powder helps bone formation around the implant and acts as a scaffold, guiding surrounding normal bone to grow into the bone powder. After using bone powder, the bone environment and conditions around the implant can be improved, allowing the implant to survive and last longer. However, before the bone powder fuses with the bone tissue around the implant, there is a problem of bone powder leaking out from between the healing abutment and soft tissue.

[0050] Therefore, this utility model provides a bone graft healing abutment to guide the healing of soft tissue around the implant before the prosthesis is placed, guide and promote bone tissue growth around the implant, reduce the risk of bone resorption around the implant, provide support for the implant, and prevent the implant from shifting during the healing process. It can be used especially when bone powder is placed in the soft tissue around the implant due to bone defects. Before the bone powder grows into the normal bone, it prevents the bone powder from leaking into the oral cavity from the gap between the gum and the abutment, ensuring that the bone powder fuses normally with the bone tissue around the implant, and ensuring that the bone powder forms bone around the implant to form a stable bone tissue structure.

[0051] Please see Figure 1 and Figure 2 In a specific embodiment, the bone graft healing abutment includes a main body 1 and a cover plate 2. The main body 1 is used to directly connect with the implant; the cover plate 2 is used to cover the gum, especially to cover the gap between the gum and the main body 1. In addition, the cover plate 2 can also serve to support and limit the main body 1.

[0052] The main body 1 includes a first end 100 and a second end 101, which are the two ends of the main body 1, respectively. The first end 100 is used to connect with the implant, and the second end 101 is used to support the gingiva, guide the healing of the soft tissue around the implant, form a soft tissue seal around the implant neck, prevent gingival recession and collapse, and also prevent food debris and foreign body fragments from entering the implant. The cover plate 2 is located at the second end 101, and the cover plate 2 protrudes radially from the main body 1 to the outside of the second end 101, forming a gingival covering portion 200 surrounding the second end 101.

[0053] The main body 1 of the bone graft healing abutment is connected to the implant via a first end 100 and a cover plate 2 via a second end 101. The cover plate 2 is located at the second end 101 and protrudes radially outward from the second end 101, forming a gingival covering portion 200 surrounding the second end 101. After the first end 100 is connected to the implant, the gingival covering portion 200 covers the gingiva, especially the gap between the gingiva and the second end 101, thereby preventing bone powder from leaking out of the gap, ensuring normal fusion of bone powder with the bone tissue around the implant, and ensuring bone formation around the implant to form a stable bone tissue structure. In addition, the cover plate 2 covering the gingiva also provides support and positioning for the main body 1.

[0054] In some embodiments, the cover plate 2 is a thin plate, such as a thickness of 5 micrometers to 1 millimeter. The edges of the thin plate are rounded to avoid scratching soft tissue.

[0055] Please see Figure 3In some embodiments, the cover plate 2 is arranged radially from the center outward as a connecting area 201 and a covering area 202, the covering area 202 being the gingival covering portion 200, and the connecting area 201 being connected to the end face of the second end 101.

[0056] The connecting area 201 is circular, and the diameter of the connecting area 201 is the same as the diameter of the end face of the second end 101. The entire connecting area 201 just connects and covers the end face of the second end 101; the covering area 202 is a concentric annulus.

[0057] Please see Figure 4 In some embodiments, the cover plate 2 is an annular plate, which is the gingival covering part 200. The annular plate is fitted onto the second end 101, and the inner ring of the annular plate is connected to the circumferential surface of the second end 101.

[0058] The inner diameter of the annular plate is adapted to the diameter of the end face of the second end 101. When the inner circle of the annular plate is connected to the circumferential surface of the end face of the second end 101, the annular plate is flush with the end face of the second end 101.

[0059] Please see Figure 1 , Figure 3 or Figure 4 To prevent the gingival cover 200 from adhering to the gums for an extended period and becoming difficult to remove, in some embodiments, the gingival cover 200 is provided with several anti-adhesion holes 203 to reduce the contact surface. In addition, during the installation of the bone graft healing abutment, the anti-adhesion holes 203 can be used to check whether the installation is in place, thus preventing the cover plate 2 from affecting the installation view.

[0060] In some embodiments, a plurality of anti-adhesion holes 203 are arranged at equal intervals around the center of the cover plate 2.

[0061] Please see Figure 1 In some embodiments, the first end 100 is provided with an external thread 1000, and the first end 100 is threadedly connected to the internal thread of the implant through the external thread 1000.

[0062] Please see Figure 2 In some embodiments, the second end 101 is cylindrical, which is a columnar healing abutment, and can be applied to scenarios that require a columnar healing abutment.

[0063] Please see Figure 5 In some embodiments, the diameter of the second end 101 gradually increases in the direction away from the first end 100 until it becomes a frustum, which is a conical healing abutment. It is wider at the top and narrower at the bottom. Soft tissue is formed at different heights of the healing abutment, and the diameter of the resulting gingival cuff is also different. The height can be adjusted according to actual needs.

[0064] Please see Figure 1 , Figure 2 or Figure 3 In some embodiments, the main body 1 further includes an intermediate section 102 located between the first end 100 and the second end 101. The diameter of the intermediate section 102 is smaller than the diameter of the second end 101. The intermediate section 102 is used to fit into the inner cavity of the implant. The first end 100 is screwed into the implant until the intermediate section 102 enters the implant and is then fully tightened.

[0065] Please see Figure 2 or Figure 5 In some embodiments, the intermediate segment 102 gradually increases in size towards the direction away from the first end 100 until it becomes a frustum shape. The part of the implant body opposite to the intermediate segment 102 also corresponds to a frustum shape. It is screwed into the implant body at the first end 100. When the intermediate segment 102 enters the implant body, it is completely screwed in. Through the characteristic of being narrow at the bottom and wide at the top, the first end 100 is restricted from moving further down, and the installation height of the entire bone graft healing abutment relative to the implant body is restricted, so as to avoid the bone graft healing abutment being installed too deep.

[0066] Please see Figure 1 , Figure 2 or Figure 3 In some embodiments, the bone graft healing abutment also includes a wrench groove 3, which passes through the center and the second end 101 of the cover plate 2 in sequence. The wrench can rotate the entire bone graft healing abutment through the wrench groove 3 to complete the installation and removal of the bone graft healing abutment.

[0067] In some embodiments, the wrench groove 3 is a hexagonal wrench groove, or it can be a cross hexagonal wrench, a flat hexagonal wrench, etc.

[0068] For example, please refer to the hexagonal wrench slot. Figure 3 In some embodiments, the cover plate 2 is arranged radially from the center outward as a connecting area 201 and a covering area 202, and the wrench groove 3 passes through the center of the cover plate 2, the center of the end face of the second end, and extends into the second end.

[0069] Please see Figure 4 In some embodiments, the cover plate 2 is an annular plate, and the wrench groove 3 passes through the center of the end face of the second end and extends into the second end, indirectly passing through the hollow position in the middle of the annular plate.

[0070] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
