Spacer and method of menufacturing same

A method of manufacturing a spacer, the spacer comprising a plurality of grip portions formed such that the plurality of grip portions surrounds parts around teeth disposed at both sides of a tooth loss space so as to maintain the tooth loss space, the spacer comprising a bridge connecting the plurality of grip portions to each other, and the method comprising:

• a data obtaining process obtaining 3D scanning data of a teeth arrangement comprising the tooth loss space by using a 3D scanning device;
• a data processing process generating a plurality of grip portions processing lines surrounding the parts around the teeth disposed at the both sides of the tooth loss space and generating a bridge processing line connecting the plurality of grip portions processing lines to each other, on the 3D scanning data;
• and
• a laser cutting process laser cutting a base material having a flat plate shape formed of a shape memory alloy material on the basis of processing line data comprising the plurality of grip portions processing lines and the bridge processing line, thereby forming a body portion forming body having a basic shape of the body portion on the base material.
