Quality
Dental Lab Quality Control Process
A practical look at how a structured quality process moves a case from intake to shipping verification.
Why a process matters more than a final check
A single final inspection cannot correct a case that was planned on incomplete information. A practical quality process places checkpoints at the points where errors can still be corrected: at intake, at design, in production and before shipping. Material records are part of the same process — see material traceability in a dental lab.
Case intake review
The intake stage confirms the prescription details that drive everything else: tooth number, restoration type, material, shade, implant system where relevant and delivery expectations. Missing or conflicting information is clarified before production begins.
Scan and impression review
Digital cases are reviewed for margin visibility, scan completeness, occlusal clearance and any implant component mismatch. Conventional impressions are checked for similar detail. Catching a margin problem here is far cheaper than after milling.
CAD design review
Design review covers margin placement, cement space, occlusal clearance, proximal contact strength, connector dimensions for bridges and emergence profile for implant cases. Design confirmation can be requested when a case warrants it.
Material verification
Material type and product reference are verified against the prescription before production. Batch information can be recorded where applicable.
In-process inspection
Depending on restoration type, in-process checks cover milling, sintering, staining and glazing, framework fit, denture setup and finishing.
Final QC and shipping verification
Final review covers fit, margin, occlusion, contact, shade and surface finish, followed by packaging and shipment verification so tracking information can be provided.
What this means for your cases
The practical benefit is not a certificate — it is fewer remakes and clearer communication when a case needs additional information.
