Abstract
A computer-implemented method and system of automatically detecting and removing extraneous material from a digital dental impression includes detecting one or more dental features in a digital dental impression, filtering the one or more dental features, digitally joining the one or more dental features, and determining one or more regions of interest from the joined one or more digital dental features.
Claims21
A computer-implemented method of automatically detecting and removing extraneous material from a digital dental impression, comprising:
- detecting one or more digital tooth cusps in a digital dental impression;
- digitally joining the one or more digital tooth cusps;
- determining a first region of interest by starting at the one or more digital tooth cusps and extending along a digital surface until reaching one or more first region endpoints;
- and
- determining a second region of interest by starting at the one or more first region endpoints and extending along the digital surface until reaching one or more second region endpoints.
A non-transitory computer readable medium storing executable computer program instructions for digitally processing a digital dental impression, the computer program instructions comprising instructions for:
- detecting one or more digital tooth cusps in a digital dental impression;
- digitally joining the one or more digital tooth cusps;
- determining a first region of interest by starting at the one or more digital tooth cusps and extending along a digital surface until reaching one or more first region endpoints;
- and
- determining a second region of interest by starting at the one or more first region endpoints and extending along the digital surface until reaching one or more second region endpoints.
A digital impression processing system for creating a digital model from a CT scan, comprising:
- a processor;
- a computer-readable storage medium comprising instructions executable by the processor to perform steps comprising:
- detecting one or more digital tooth cusps in a digital dental impression;
- digitally joining the one or more digital tooth cusps;
- determining a first region of interest by starting at the one or more digital tooth cusps and extending along a digital surface until reaching one or more first region endpoints;
- and
- determining a second region of interest by starting at the one or more first region endpoints and extending along the digital surface until reaching one or more second region endpoints.
