Integrated dental implant and preparation method thereof

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...

AI Technical Summary

Problems solved by technology

[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
