Abstract

Provided is a scanning jig capable of improving replacement accuracy of three-dimensional data. Provided is a scanning jig 10 for attaching to an analog 20 embedded in a model or to an artificial tooth root 30 embedded inside an oral cavity, the scanning jig including: a main body 11 formed in a bottomed cylindrical shape provided with a bottom to one end portion; a fixation member 12 of which one end side is inserted inside the cylindrical shape of the main body and the other end side is fixated to the analog or the artificial tooth root; and a magnet 13 arranged inside the cylindrical shape of the main body, wherein the main body is not provided with a hole or a groove on one end surface on a bottom side of the bottomed cylindrical shape, and the end surface is provided with an inclined surface.

First claim

The invention claimed is:

1. A scanning jig for attaching to an analog embedded in a model or to an artificial tooth root embedded inside an oral cavity, the scanning jig comprising:
a main body formed in a bottomed cylindrical shape provided with a bottom to one end portion;
a fixation member of which one end side is inserted inside the cylindrical shape of the main body and the other end side is fixated to the analog or the artificial tooth root; and
a magnet arranged inside the cylindrical shape of the main body, the magnet being arranged in a position where the magnet does not have contact with the fixation member,
wherein:
the main body is not provided with a hole or a groove on an end surface at side provided with the bottom in an axial direction of the cylindrical main body;
the end surface is provided with an inclined surface that is inclined with respect to the axial direction of the cylindrical main body; and
a cylindrical fitting part extends from the main body in the axial direction and is provided for a second end portion of the main body at a side opposite from the bottom.

2. The scanning jig according to claim 1 , wherein
for a cylindrical axis direction of the main body, the main body is, with a state of being attached to the analog or the artificial tooth root, configured such that only the fitting part has contact with the analog or the artificial tooth root.
