Abstract
A model generator generates an impression scan by scanning a polyvinyl impression and generates a stone model using the polyvinyl impression as a negative mold. A comparative analysis of the impression scan and a scan of the stone model determines a digital scaling factor that scales the impression scan to align with the stone model scan. A scan alteration system receives impression scans for dental component production processing and selects digital scaling factors generated by the model generator that scale the impression scans to align with theoretical stone model scans that would be produced by an applicable modeling and scanning process to generate a scaled surface model for use in dental component production.

A digital scaling factor system for determining an impression scan digital scaling factor and scaling impression scans to generate scaled surface models for use in dental component production, the system comprising:
- a model generator comprising a scan capture unit and a stone modeling unit, wherein the scan capture unit is configured to generate an impression scan by scanning a polyvinyl impression using a scan capture system, and a stone modeling unit configured to generate a stone model using the polyvinyl impression as a negative mold, and wherein the scan capture unit is further configured to generate a stone model scan by scanning the stone model after curing using a same type of scan capture system that was used to scan the impression;
- a comparison module configured to perform a comparative analysis of the impression scan and stone model scan and determine a digital scaling factor that scales the impression scan to align with the stone model scan;
- a scan alteration system configured to receive an impression scan for scaling that was generated from a polyvinyl impression and select a digital scaling factor that would align the impression scan for scaling with a stone model scan of a stone model that would be generated from the polyvinyl impression that was scanned to generate the impression scan for scaling if utilizing an identified type of scan capture system and stone modeling process, wherein the scan alteration system includes a scan alteration generator including a digital scaling factor processor configured to scale the impression scan for scaling by the selected digital scaling factor to generate a scaled surface model.
