  • Publication number: 20250072996
    Abstract: Proposed is a manufacturing method of a retainer provided with a body part having a first surface being in contact with a teeth surface of a plurality of teeth forming a teeth arrangement so as to support the teeth arrangement. The manufacturing method includes a process of acquiring three-dimensional scanning data of the teeth arrangement, a data processing process in which processing line data for manufacturing the body part are generated, and a laser cutting process in which a body forming part is manufactured from a base material formed of a shape memory alloy material. In the data processing process, tangential lines that extend along the teeth surface of the teeth arrangement are formed and collected, and a first processing line formed by connecting, to each other, tangential line portions in a tangential line group body and a second processing line spaced apart from the first processing line are generated.
