A kind of dental implant and its 3D printing manufacturing method

Abstract

The invention provides a dental implant including a dental implant body and an abutment part, wherein the abutment part is arranged on the dental implant body, and the abutment part is formed integrally with the dental implant body. The invention also provides a 3D printing preparation method of the dental implant. The 3D printing preparation method disclosed by the invention can overcome shortages of an individuated dental implant manufactured by a conventional mechanical processing technology, effectively solves the processing technology problems of a complex dental implant structure, at the same time, makes the design form and type of the dental implant more open, improves the processing efficiency, greatly reduces the processing cost, and reduces the post-treatment process. The requirement on the equipment accuracy is not as high as mechanical-processed equipment, the roughness degree of an outer surface is controllable, and surface sandblasting treatment procedures are reduced. An integrally-formed structure of the dental implant provided by the invention can avoid the micro leakage problem of a traditional two-section connection. The dental implant provided by the invention is more beneficial for immediate implantation, reduces bone loss, reduces the operation process, and allows a operation to become a minimally invasive operation or even a noninvasive operation.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to a dental implant and a 3D printing manufacturing method of the dental implant. Background technique [0002] The traditional oral implant system usually includes three parts: a dental implant implanted in the alveolar bone and combined with bone tissue, an artificial crown, and an oral dental implant abutment that connects the body and the artificial crown. At present, most of the commonly used dental implant systems in the world are two-stage, that is, dental implant plus abutment plus connecting screw. [0003] At present, all dental implants and abutments on the market are completed by machining, which belongs to subtractive manufacturing; and the form and design of dental implants are limited by machining equipment, generally cylindrical, conical or threaded. ;The dental implant and the abutment are not integrated, and the sealing of the two-stage joint is guaranteed by the ma...

AI Technical Summary

Problems solved by technology

[0003] At present, all dental implants and abutments on the market are completed by machining, which belongs to subtractive manufacturing; and the form and design of dental implants are limited by machining equipment, generally cylindrical, conical or threaded. ;The dental implant and the abutment are not integrated, and the sealing of the two-stage joint is guaranteed by the machining accuracy, which requires high precision of the machine tool. If the sealing is not good, it will have a bad influence on the dental implant effect; It is usually produced in batches, but it is difficult to complete the personalized dental implant according to the shape of the patient's tooth root, or the cost is high and the processing efficiency is low
