Abstract
Systems and methods for imaging a dental occlusal registration impression; developing a digital 3D surface contour model of the occlusal registration impression from the image data; electronically transferring the data representing the digital 3D surface contour model of the occlusal registration impression; fabricating a physical replicate of the occlusal registration impression; correlating features on upper and lower jaw dental models with features on the replicate occlusal registration impression model; and determining occlusal alignment of the upper and lower jaw dental models using the replicate occlusal registration impression model.
Claims20
A method for determining the occlusal alignment of jaw dental models using a physical replicate of an occlusal bite registration impression, comprising:
- a) creating a digital 3D surface contour model of the bite registration impression;
- b) fabricating a physical replicate bite model of the bite registration impression using the data from the digital 3D surface contour model of the bite registration impression;
- c) correlating features on the upper and lower jaw dental models with features on the replicate bite model;
- and
- d) aligning the occlusal contact of the upper jaw and lower jaw dental models by nesting the upper jaw dental model occlusal features into the corresponding features in the replicate bite model features and nesting the lower jaw dental model occlusal features into its corresponding features in the replicate bite model.
A system for determining the occlusal alignment of jaw dental models using a replicate of an occlusal bite registration impression, comprising:
- a) means for imaging the surface of the bite registration impression;
- b) means for using the image data to create a digital 3D surface contour model of the bite registration impression;
- c) means to fabricate a physical replicate bite model from the data file for the digital 3D surface contour model of the bite registration impression;
- and
- d) means for using the replicate bite model to align the occlusal surfaces of the upper jaw and lower jaw dental models.
