Why cases are remade — and what we changed
After reviewing remake records, the causes fall into four groups. Three of them are preventable before production starts.
Cause 1: the record did not represent the mouth
A scan with an unclear margin, an impression with a drag or a bite registration taken at the wrong vertical dimension. The restoration is correct for the data and wrong for the patient.
Our response: a data check before quoting. We reject or request a rescan before production rather than after.
Cause 2: the prescription and the file disagreed
Shade, material or implant platform specified in the message and contradicted in the scan. We now confirm both in writing before design.
Cause 3: chair-side adjustment exceeded the design
A crown that was correct but was adjusted heavily to fit a changed occlusion. Photographic QC at the same magnification makes the difference visible.
Cause 4: genuine production defects
Porosity, a colour shift after sintering, a connector that was too thin. These are our responsibility and are remade at our cost. Reviewing them is how the process improves.
