Abstract

The present inventive concept relates to a method for obtaining a subgingival marginal shape for a prosthesis design non-invasively by means of an optical coherence tomography (OCT) scanner for obtaining a subgingival marginal shape and an intraoral scanner for obtaining a tooth surface shape, the method including the steps of: obtaining a surface shape of a prepared tooth by means of the intraoral scanner; obtaining the subgingival marginal shape (crown margin line) of the prepared tooth by means of the OCT scanner; and merging the surface shape of the prepared tooth with the subgingival marginal shape to obtain a final three-dimensional shape of the prepared tooth.
