Abstract
A method for preparing a tooth crown may include generating a 3D model of an external surface of a patient's tooth and generating a 3D model of an external surface of a first crown based on the 3D model of the external surface of the patient's tooth. The method may also include preparing the patient's tooth to receive the first crown while generating the 3D model of the external surface. A 3D model of the prepared tooth my be generated. A 3D model of an internal surface of the first crown may also be generated. The 3D model of the external surface and the 3D model of the internal surface may form a 3D model of the first crown.
Claims20
A system for preparing a tooth crown, the system comprising:
- non-transitory computer readable medium with instruction that, when executed by a processor, cause the system to carry out a method, the method including:
- generating a 3D model of an external surface of a first crown based on 3D data of the external surface of a patient's tooth;
- generating a 3D model of an internal surface of the first crown;
- outputting instructions to fabricate a physical first crown based on the 3D model of the external surface of the first crown and the 3D model of the internal surface of the first crown while the patient's tooth is being prepared to receive the first crown;
- generating a 3D model of a second crown based on a 3D model of the internal surface of the physical first crown and the 3D model of the external surface of the first crown, wherein the 3D model of the internal surface of the physical first crown is generated after fitting the physical first crown to the patient's tooth;
- generating instructions for fabricating a physical second crown based on the 3D model of a second crown.
A system for preparing a tooth crown, the system comprising:
- a non-transitory computing device readable medium storing instructions executable by a processor to cause a computing device to perform a method, the method including:
- generating a 3D model of an external surface of a first crown based on 3D scan data of the external surface of a patient's tooth;
- outputting instructions to fabricate a physical first crown based on the 3D model of the external surface of the first crown while the patient's tooth is being prepared to receive the first crown;
- generating a 3D model of a second crown based on a 3D model of an internal surface of the physical first crown and the 3D model of the external surface of the first crown, wherein the 3D model of the internal surface of the physical first crown is generated after fitting the physical first crown to the patient's tooth;
- generating instructions for fabricating a physical second crown based on the 3D model of a second crown.
