Description

Technical Field

[0001] The utility model belongs to the field of dental implantation, and in particular relates to a dental implant for bone-level implantation. Background Art

[0002] For the existing dental implants for bone-level implantation in the market, the upper part of the implant is a flat surface. During the implantation surgery, the upper surface of the alveolar bone at the implantation position needs to be flattened, and the alveolar bone needs to have sufficient width to perform the implantation surgery. However, there are significant differences in the width of the alveolar bone and the inclination arc of the alveolar bone among different patients. For many patients who cannot directly use the existing bone-level implants due to alveolar bone limitations, bone grafting surgery needs to be performed first. After the bone surface at the surgery implantation position is flattened and the alveolar bone width is sufficient, the dental implant can be implanted. The whole surgical process has many steps, a long surgical cycle time, more pain for patients, and a heavy burden on medical staff.

[0003] The existing dental implants mainly focus on bone-level implantation. The upper part of the implant is a complete flat surface. The alveolar bone at the implantation position needs to be flattened to fit the implant. When the width of the alveolar bone is insufficient, bone augmentation and bone grafting surgery are required; the surgical process is complex, the cycle is long, and patients have more pain. Content of the Utility Model

[0004] In view of this, the utility model aims to provide a dental implant for bone-level implantation, which is suitable for the implantation surgery of patients with narrow alveolar bone width, and can reduce the amount of bone grafting during the surgical process of patients or perform the implantation surgery of dental implants without bone grafting.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] A dental implant for bone-level implantation, the whole is in a conical structure; double-threaded threads are provided on the circumferential surface of the dental implant;

[0007] Cutting grooves are also provided on the circumferential surface of the dental implant;

[0008] A hexagonal hole is provided at the top of the dental implant, and a threaded hole is further provided at the bottom of the hexagonal hole. The hexagonal hole and the threaded hole form a stepped hole.

[0009] Further, the top of the dental implant forms an end face that is integrally circular;

[0010] The end face includes a horizontal section and an arc section; the perimeter of the horizontal section is smaller than the perimeter of the arc section;

[0011] The horizontal section is in the same plane as the horizontal line; the arc section is in an arc surface structure that is concave from both ends to the middle on the end face.

[0012] Furthermore, the height difference between the highest point of the horizontal section and the lowest point of the arc section is 0.5 mm - 1 mm.

[0013] Furthermore, the number of the cutting grooves is three, which are evenly arranged on the circumferential surface of the dental implant.

[0014] Furthermore, the three cutting grooves are all arranged on four threads.

[0015] Furthermore, a conical sealing surface is formed above the hexagonal hole.

[0016] Furthermore, the circumferential surface of the dental implant is subjected to sandblasting and acid etching treatment.

[0017] Compared with the prior art, the dental implant for bone-level implantation of the present utility model has the following advantages:

[0018] (1) For the dental implant for bone-level implantation of the present utility model, the upper part of the implant is designed to be composed of a plane and an arc surface. The radian of the implant and the radian of the alveolar bone can be well matched, significantly reducing the requirements for the width of the alveolar bone in the implantation surgery. It is possible to achieve the implantation surgery of the dental implant without bone grafting or only with a small amount of bone grafting.

[0019] (2) For the dental implant for bone-level implantation of the present utility model, by setting double-threaded screws and deep spiral grooves, the operation time can be reduced, the initial stability of the implant implanted into the alveolar bone can be improved while collecting autologous bone. The implant threads are conical and provided with cutting grooves, which improves the self-tapping performance of the implant. The lower part of the implant is treated with sandblasting and acid etching (SLA), forming uniform small pit holes, which is very beneficial for the combination with the alveolar bone.
