[0004] But it also mainly has the following defects: (1) the hardness of the implant is poor, the taper hole is connected with the denture and is stressed, and the damage rate is high
(2) The molding accuracy of 3D printing is poor, and the 3D printed implant cannot be clamped and machined again, resulting in poor fit between the taper hole and the crown, affecting the quality of use, resulting in a high mismatch rate and high scrap rate

Embodiment 1
[0030] Please refer to the attached Figure 1-3 , the purpose of this embodiment is to provide a one-piece dental implant, including: a tooth root part 1, the tooth root part 1 is integrally arranged at the lower part of the dental implant that can promote the growth of bone cells and can be embedded in the alveolar bone Inside, preferably, the length of the root part 1 is 6 mm, and the diameter of the root part 1 is 3 mm.
[0031] Specifically, the one-piece dental implant also includes an intragingival part 2, which is integrally arranged on the top of the root part 1, and the intragingival part 2 can be embedded in the gingiva covering the alveolar bone, and the intragingival part 2 Part 2 protects the gum tissue and does not expose the root of the tooth, does not contact the upper jaw during occlusal, and does not affect the stability of the implant.
[0032] Further, the one-piece dental implant also includes an integral part of the crown 4, and the integral part of the ...
Embodiment 2
[0044] Please refer to the attached Figure 1-3 , the purpose of this embodiment is to provide a one-piece dental implant, including: a tooth root part 1, the tooth root part 1 is integrally arranged at the lower part of the dental implant that can promote the growth of bone cells and can be embedded in the alveolar bone Inside, preferably, the length of the root part 1 is 10 mm, and the diameter of the root part 1 is 6.5 mm.
[0045] Specifically, the one-piece dental implant also includes an intragingival part 2, which is integrally arranged on the top of the tooth root part 1, and the intragingival part 2 can be embedded in the gingiva covering the alveolar bone, and the intragingival part 2 Protect the gingival tissue without exposing the root of the tooth, will not contact the upper jaw during occlusal, and will not affect the stability of the implant.

Abstract
The invention relates to the technical field of medical instruments, and provides an integrated dental implant and a preparation method thereof. The integrated dental implant includes:a tooth root part which is integrally arranged at the lower part of the integrated dental implant and can be embedded in an alveolar bone; and an intra-gingival part which is integrally arranged on the top of the tooth root part, wherein the intra-gingival part can be embedded in the gingiva covering the alveolar bone, wherein a thread part combined with an alveolar bone is arranged at the lower part of the tooth root part, and a bone trabecula part is arranged between the thread part and the intra-gingival part. During machining, the machined intra-gingival part is placed in a hole site of a 3D printing tool to be fixed, the combination face of the intra-gingival part and the tooth root part is flush with the tool plane of the 3D printing tool, and the tooth root part is subjected to 3D printing. The integrated dental implant has the beneficial effects that the machined intra-gingival part is high in hardness, so that the taper hole is connected with the false tooth and is stressed, and the damage rate is low; the tool is used for assisting 3D printing of the tooth root part, the printing forming precision is improved, and the rejection rate is greatly reduced.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to an integrated dental implant and a preparation method thereof. Background technique [0002] The current dental implants usually adopt the shape of a cylinder, and the surface of the cylinder is provided with threads to be installed in the alveolar bone, and the contact surface between the existing dental implant and the alveolar ridge is a planar structure, because the teeth at the alveolar ridge The alveolar bone has a curved end face, so it is necessary to grind the alveolar bone at the alveolar ridge so that the curvature is consistent with that of the dental implant. It is easy to cause food residues to stay between the teeth, and it is easy to corrode the teeth or cause gingival inflammation and other problems, resulting in stress concentration. It will also lead to loosening of the implant and affect osseointegration. The materials for implants are mainly titanium and titan...
