Direct Answers
Why does ACE DNTL LAB use a three-stage review?
Because cosmetic dental cases fail in different domains — colour, proportion, occlusion — and each domain demands focused attention. A combined single-pass review misses minor issues in any one of the three. Separating the reviews accepts the modest time cost in exchange for substantial reliability. Every aesthetic case passes the three stages before bonding.
What happens if a case fails one of the three reviews?
It returns to the bench with specific written feedback identifying which stage it failed and why. The case is reworked and re-reviewed. Nothing leaves the laboratory until all three stages pass. The failure and the rework are documented in the case file, which becomes part of the patient's clinical record.
How is the colour review different from a normal shade match?
A normal shade match is performed once, at consultation, against a shade tab. The colour review at ACE DNTL LAB is performed against the patient's diagnostic photography under the same daylight-corrected lighting that will be used at bonding — assessing the match across cervical, mid-tooth, and incisal zones, not at a single point. This eliminates the failure mode in which a case looks correct in studio photography and surprises everyone at try-in.
How does the three-stage review connect to the ACE Smile Index?
The Index defines what excellence looks like — ten criteria with defined scoring scales. The three-stage review is one of the operational mechanisms that ensures the Index can be met case after case. Stages 1, 2, and 3 specifically evaluate criteria 2+6 (colour and translucency), 3+4 (proportion and characterisation), and 8 (occlusal harmony) of the published framework.
