Abstract
Disclosed are example embodiments of methods and systems for identifying and quantifying manufacturing defects of a manufactured dental prosthesis. Certain embodiments of the system for performing quality control on manufactured dental prostheses includes: a quality control module configured to determine whether the dental prosthesis is a good or a defective product based at least on a differences model generated by comparing a design model and a scanned model of the manufactured dental prosthesis.
Claims13
A method for performing quality control on a dental prosthesis manufacturing system, the method comprising:
- providing a computer-aided design (CAD) model of a dental prosthesis;
- manufacturing a physical dental prosthesis based on the CAD model;
- scanning the physical dental prosthesis to create a 3D scan model;
- generating a differences model by comparing the CAD model with the 3D scan model and compiling offsets between portions of a data set of the CAD model and corresponding portions of a data set of the 3D scan model;
- modifying the differences model by omitting from the differences model portions of the data set corresponding to an occlusal surface of the dental prosthesis;
- and
- analyzing the differences model to determine whether the dental prosthesis manufacturing system is operating within a predetermined tolerance threshold.
