Abstract
A wax model of a required coping is produced using CNC machining techniques based on a virtual model of the coping created from digital data obtained from the intraoral cavity. The dental coping is then fabricated from the wax model.
Claims34
A method for the manufacture of at least a prosthesis portion of a dental prosthesis of at least one tooth to be fitted over a tooth preparation, comprising:
- fabricating a wax model of the prosthesis portion, wherein
- at least a first, inner surface of said wax model is manufactured by computerized numerical control (CNC) milling of the model according to suitable CNC instructions, wherein
- said CNC instructions are based on a three-dimensional (3D) virtual model of the prosthesis portion that is virtually generated based on processing of 3D digital data of at least said tooth preparation, and
- further comprising the step of manufacturing the prosthesis portion from the wax model.
A method for the manufacture of a prosthesis part wax model to be used in the manufacture of a prosthesis portion of a dental prosthesis of at least one tooth to be fitted over a tooth preparation, comprising fabricating a wax model of the prosthesis portion, wherein at least a first, inner surface of said wax model is manufactured by computerized numerical control (CNC) milling of the model according to suitable CNC instructions, wherein said CNC instructions are based on a three-dimensional (3D) virtual model of the prosthesis portion that is virtually generated based on processing of 3D digital data of at least said tooth preparation.
A system for the manufacture of at least a prosthesis portion of a dental prosthesis of at least one tooth to be fitted over a tooth preparation, the system comprising:
- a processor;
- a computerized numerical control (CNC) milling machine;
- and
- manufacturing means,
- wherein the system is configured for fabricating a wax model of the prosthesis portion, wherein at least a first, inner surface of said wax model is manufactured by computerized numerical control (CNC) milling of the model according to suitable CNC instructions, wherein said CNC instructions are based on a three-dimensional (3D) virtual model of the prosthesis portion that is virtually generated based on processing of 3D digital data of at least said tooth preparation,
- wherein the system is further configured for manufacturing the prosthesis portion from the wax model.
A system for the manufacture of a prosthesis part wax model to be used in the manufacture of a prosthesis portion of a dental prosthesis of at least one tooth to be fitted over a tooth preparation, the system comprising:
- a processor, and
- a computerized numerical control (CNC) milling machine,
- wherein the system is configured for fabricating a wax model of the prosthesis portion, wherein at least a first, inner surface of said wax model is manufactured by computerized numerical control (CNC) milling of the model according to suitable CNC instructions, wherein said CNC instructions are based on a three-dimensional (3D) virtual model of the prosthesis portion that is virtually generated based on processing of 3D digital data of at least said tooth preparation.
