Rx Validation Engine

Every error caught
before fabrication
is a remake that never happens.

40+ clinical rules validate every Rx in real time. Impossible combinations, missing data, and contradictions — blocked before they reach the lab.

Inconsistencies caught

Surgeons aren't materials scientists. They specify what they want clinically, but they don't always know which combinations are physically impossible, structurally risky, or clinically contradictory. The lab catches them — but only after design has started.

PMMA selected as final material
The surgeon doesn't know PMMA is provisional-only. The lab finds out when it opens the order.
Cement-retained on a 20-degree implant
Cement washout risk. The lab recommends screw-retained — but design has already started.
Cantilever bridge with 3 pontics
Excessive stress on the abutment. The case fails clinically within 6 months.
Denture without Shimbashi measurement
No vertical dimension of occlusion, the lab works blind. Result: guaranteed remake.
Zirconia framework + acrylic material
Incompatible materials. They don't bond. The case comes back in 48 hours.
How it works

Validation in real time

01
Surgeon fills an Rx field
Picks material, retention type, margin, implant system — every field in the Rx Builder is a validation point.
02
The engine checks 40+ rules
Every value is cross-checked against 6 categories of clinical rules: material compatibility, contraindications, missing data, structural limits, retention angles, and esthetic risk.
03
Result shown instantly
No popups. No extra steps. The result appears next to the field with its severity level: BLOCK, WARN, or INFO.
04
The lab sees the validation status
When the Rx reaches the lab, every field shows its validation status. Zero surprises. Zero calls to clarify.

40+ rules. 10 examples.

Every rule guards a real clinical failure point.

Retention-Angle
Cement-retained + implant angle > 15 degrees
Warn
Cement washout risk above 15 degrees. Screw-retained recommended.
Clinical Contraindication
Knife-edge margin + bruxism = true
Block
Knife-edge margins fracture under bruxism. Use chamfer or shoulder.
Material Compatibility
PMMA framework + type = Finals
Block
PMMA is provisional-only. Pick zirconia, PFM, or hybrid for finals.
Retention-Access
Screw-retained + no screw access selected
Block
Screw access position required. Pick palatal, lingual, or occlusal.
Missing Data
Finals + no shade photo
Warn
Shade photo required for accurate color. Upload before sending.
CR Complexity
Multi-unit bridge + CR not verified
Warn
Centric not verified on a multi-unit case. High remake risk.
Structural Limit
Cantilever bridge + > 2 pontics
Block
Cantilever capped at 2 pontics. Excessive stress on the abutment.
Esthetic Risk
Thin biotype + stock abutment
Info
Stock abutments can show a dark line on thin tissue. Custom recommended.
Material Compatibility
Zirconia framework + acrylic material
Block
Acrylic is not compatible with zirconia frameworks. Pick a compatible material.
Missing Data
Denture + no VDO measurement
Block
Shimbashi measurement required for dentures. Measure and photograph VDO.

Case #34 — Live validation

This is what real validation looks like inside TrazaLab.

Rx Validation
1 critical issue — fix before sending
Knife-edge margin incompatible with bruxism
Switch margin to chamfer or shoulder. Knife-edge fractures under bruxism forces.
Block
Cement-retained on a 20-degree implant
Elevated cement washout risk. Consider screw-retained.
Warn
No shade photo
The lab will have to estimate shade — elevated remake risk.
Warn
Framework-material compatibility verified
Monolithic zirconia valid for this case.
Pass
Implant system compatible with abutment
Implant system compatible with the selected abutment type.
Pass
Severity levels

Three levels. One logic.

BLOCK

Rx cannot be sent

The surgeon must fix it before continuing. Prevents physically impossible or clinically dangerous combinations that would guarantee a remake.

PMMA framework selected for a final restoration. PMMA is provisional-only.
WARN

Can be sent, but flagged

The lab sees the warning. The surgeon acknowledges the risk. Both sides are informed — if a remake happens, the call was deliberate.

Cement-retained on a 20-degree implant. Elevated cement washout risk.
INFO

Suggestion for better results

No action required. An evidence-based recommendation to optimize the outcome. The surgeon decides whether to apply it.

Thin biotype with stock abutment. Custom abutment recommended to avoid a dark line.
Integration

VALIDATION
ENGINE
Rx Builder
Runs in real time as the surgeon fills each field. Validation without friction.
TrazaChat
Auto-posts warnings to the case chat when the Rx is sent. Lab and surgeon aligned.
Growth Engine
Tracks approval/rejection rates per surgeon. Flags systematic error patterns.
WhatsApp
Notifies the surgeon on BLOCK rules. The error lands instantly on the channel they always check.

The cheapest remake is the one that never happens.

Every Rx error caught before fabrication saves $200-800 in materials, labor, and time.
