Quality Assurance |
How we do it right the first time
Each case at Killian Dental Ceramics goes through an extensive administrative and technical Quality Assurance & Quality Control (QC) process. The doctor’s general case preferences are kept on file and attached to each new case we receive. The general preferences are updated from meetings, telephone conversations and any feedback received from the doctor. Additionally, the contents of each case are recorded upon arrival and verified to ensure that they are returned to the doctor’s office along with the finished restoration. The technical QC process is an all day activity involving Steve Killian, CDT as he instructs technicians in the laboratory about all aspects of superior crown & bridge and implant fabrication. Each case that requires correction is used as an example for demonstration of proper results. Verification of those results is observed at several steps throughout the processing of the case and at final completion. These photos visually describe some of those steps.
