A kind of integrated dental implant and preparation method thereof

Abstract

The invention relates to the technical field of medical devices, and provides an integrated dental implant and a preparation method thereof. Including: the root part, the root part is integrally arranged on the lower part of the one-piece dental implant and can be embedded in the alveolar bone; the intragingival part, the intragingival part is integrally arranged on the top of the root part, and the intragingival part can be buried It is implanted in the gingiva covering the alveolar bone; the lower part of the root part is provided with a threaded part combined with the alveolar bone, and a trabecular bone part is arranged between the threaded part and the intragingival part; during processing, the machined gingival The inner part is placed in the hole of the 3D printing tool and fixed, the joint surface of the intragingival part and the root part is flush with the tooling plane of the 3D printing tool, and the root part is 3D printed. The beneficial effects of the invention are as follows: the machined intragingival part has high hardness, so that the taper hole is connected to the denture and is subjected to force, and the damage rate is low; the use of tooling to assist 3D printing of the root part improves the printing forming accuracy and greatly reduces the rejection rate.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an integrated dental implant and a preparation method thereof. Background technique [0002] The current dental implant usually adopts 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 plane structure. The alveolar bone has an arc-shaped end face, so the alveolar bone at the alveolar ridge needs to be polished to make the curvature consistent with the dental implant. It is easy to cause food residues to remain between the teeth, and it is easy to corrode the teeth or cause problems such as gingival inflammation, and stress concentration occurs. It will also lead to the loosening of the implant and affect the osseointegration. The materials for implants are mainly titanium and titanium alloys, which have good mechanical pr...

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
