Method, system, and computer-readable medium for uncovering and planning an accurate dental preparation

摘要

A procedure for creating a dental prosthetic includes registering three-dimensional (3D) dental impression image data of a tooth restoration site and 3D x-ray image data of the tooth restoration site, and removing image data corresponding to soft tissue in the tooth restoration site from the 3D dental impression image data. A system for producing a dental prosthetic includes at least one processor operable to register 3D dental impression image data of a tooth restoration site and 3D x-ray image data of the tooth restoration site and remove image data corresponding to soft tissue in the tooth restoration site from the 3D dental impression image data.

1. A procedure for creating a dental prosthetic, the procedure comprising:
registering three-dimensional (3D) dental impression image data of a tooth restoration site and 3D x-ray image data of the tooth restoration site; automatically removing image data corresponding to soft tissue in the tooth restoration site from the 3D dental impression image data based on a distinction in the 3D x-ray image data between soft tissue and hard tissue; and demarcating, in the 3D dental impression image data, a preparation margin of a prepared tooth from which soft tissue was removed, in the tooth restoration site.
