Abstract
A phantom model of teeth set, a method for evaluating the scanning accuracy of a scanner using the same model, and a method for evaluating the 3D printing precision of a printer using the same model is disclosed. The disclosed phantom model of teeth set comprises a base layer and a layer of teeth set comprising a tooth model as positioned on the base layer, and the tooth model may be constructed such that a shape observed in one direction differs from shapes viewed in the other direction.
Claims10
A phantom model of teeth set comprising:
- a first base layer;
- a second base layer formed on a top surface of the first base layer, such that the second base layer covers a majority of the top surface of the first base layer;
- a plurality of patterns formed at both upper edges of the second base layer and configured to improve scanning accuracy;
- and
- model teeth formed on a top surface of the second base layer, each model tooth being spaced apart from an adjacent model tooth such that the model teeth do not contact each other,
- wherein a shape of each model tooth, when viewed from a front, rear, top, left, or right side, differ from a shape of any other one of the model teeth.
