Detachable denture and preparation method thereof

Abstract

The present invention relates to the field of a denture, and especially relates to a detachable denture and a preparation method thereof. The denture comprises a mounting unit, also includes an upper dental crown, a lower dental crown, an upper dental base and a lower dental base which are formed by 3D printing, the upper dental crown and the lower dental crown are filled with filling bodies, the mounting unit comprises an implant abutment and an abutment yoke body, the implant abutment is fixed in the upper dental crown and the lower dental crown, the abutment yoke body is fixed in the dental base and the lower dental base, the implant abutment and the abutment yoke body are in magnetic connection, and connection gaps between the upper dental crown and the upper dental base and between the lower dental crown and the lower dental base are filled with paste. The upper dental crown and the lower dental crown are overall structures comprising a plurality of dental crowns, the upper dental crown and the lower dental crown are printed directly by 3D printing technology after tooth-arrangement design by use of a computer, the integrity is good, the upper dental crown and the lower dental crown are not easy to deform and misplace, by the tooth-arrangement design by use of the computer, the tooth-arrangement level of a technician can be improved maximally, a lot of work steps are saved, and cost is saved for patients.

Description

technical field [0001] The invention relates to the field of dentures, in particular to a detachable denture and a manufacturing method thereof. Background technique [0002] In the prior art, the denture includes a tray and a crown, and the crown and the tray are fixedly connected, inseparable and inseparable as a whole. When a certain part is damaged, the entire denture needs to be replaced, and the cost of use is high, and the production of the denture is very difficult. Pay attention to the technology of skilled workers and rely entirely on manual operation, which is prone to unstable quality due to the lack of technical proficiency and sense of responsibility of the operating technicians, and high production costs and low efficiency, resulting in high manual production costs for dentures.
