Abstract
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.
Claims20
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.
A system for producing a dental prosthetic, the system comprising:
- a memory storing a program;
- and
- at least one processor operating under control of the program to register three-dimensional (3D) dental impression image data of a tooth restoration site and 3D x-ray image data of the tooth restoration site, automatically remove 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 demarcate, 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.
A non-transitory computer-readable medium storing sequences of instructions, the sequences of instructions including instructions which, when executed by a computer system, cause the computer system to:
- register three-dimensional (3D) dental impression image data of a tooth restoration site and 3D x-ray image data of the tooth restoration site;
- automatically remove 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
- demarcate, 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.
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 volume 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 volume 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.
