Abstract
Herein are provided methods, systems, computer-readable media, techniques and processes for adjusting dental prostheses based on soft tissue. These include allowing an operator to define the surface of a dental prosthesis, such as an abutment, that is proximal to the patient's gum relative to a 3D scan of the patient's gums. The operator can define the offset of that surface as well as the limits of that surface.
Claims20
A computer-implemented method for adjusting dental prostheses based on soft tissue, comprising:
- receiving a 3D scan of soft tissue of the patient, said 3D scan of the soft tissue of the patient comprising at least an emergence portion, said emergence portion of the 3D scan of the soft tissue extending from an area associated with an implant attached to said patient, to an area where a dental prosthesis attached to said implant would emerge from said soft tissue;
- receiving emergence limit information for an emergence surface of a 3D model of the dental prosthesis;
- receiving desired offset information for the emergence surface of the 3D model of the dental prosthesis, wherein the offset information comprises a distance between the emergence surface of the 3D model of the dental prosthesis and the emergence portion of the 3D scan of the soft tissue;
- determining, using one or more computing devices, a shape of the emergence surface of the 3D model of the dental prosthesis based on the emergence portion of the 3D scan of the soft tissue, the emergence limit information, and the offset information;
- and
- producing manufacturing data related to the dental prosthesis.
A system for adjusting dental prostheses based on soft tissue, comprising one or more computing devices, said one or more computing devices being configured to:
- receive a 3D scan of soft tissue of the patient, said 3D scan of the soft tissue of the patient comprising at least an emergence portion, said emergence portion of the 3D scan of the soft tissue extending from an area associated with an implant attached to said patient, to an area where a dental prosthesis attached to said implant would emerge from said soft tissue;
- receive emergence limit information for an emergence surface of a 3D model of the dental prosthesis;
- receive desired offset information for the emergence surface of the 3D model of the dental prosthesis, wherein the offset information comprises a distance between the emergence surface of the 3D model of the dental prosthesis and the emergence portion of the 3D scan of the soft tissue;
- determine a shape of the emergence surface of the 3D model of the dental prosthesis based on the emergence portion of the 3D scan of the soft tissue, the emergence limit information, and the offset information;
- and
- produce manufacturing data related to the dental prosthesis.
A computer-readable storage medium comprising computer-executable instructions for adjusting dental prostheses based on soft tissue, said computer-executable instructions, when running on one or more computing devices, performing a method comprising:
- receiving a 3D scan of soft tissue of the patient, said 3D scan of the soft tissue of the patient comprising at least an emergence portion, said emergence portion of the 3D scan of the soft tissue extending from an area associated with an implant attached to said patient, to an area where a dental prosthesis attached to said implant would emerge from said soft tissue;
- receiving emergence limit information for an emergence surface of a 3D model of the dental prosthesis;
- receiving desired offset information for the emergence surface of the 3D model of the dental prosthesis, wherein the offset information comprises a distance between the emergence surface of the 3D model of the dental prosthesis and the emergence portion of the 3D scan of the soft tissue;
- determining, using one or more computing devices, a shape of the emergence surface of the 3D model of the dental prosthesis based on the emergence portion of the 3D scan of the soft tissue, the emergence limit information, and the offset information;
- and
- producing manufacturing data related to the dental prosthesis.
