In a full-arch AOX (All-on-X) case, precision is everything. One small alignment error at the beginning can lead to misfit, occlusal problems, or implant stress in the final prosthesis.
That’s why fiducial alignment plays a critical role in the digital workflow.
🦷 What Is Fiducial Alignment?
Fiducial markers are reference points used to accurately merge:
-
CBCT data
-
Intraoral scans
-
Photogrammetry or scan body data
These markers ensure that the implant position in the digital design matches the true clinical position in the patient’s mouth.
🦷 Why It Matters in AOX Cases
AOX restorations require:
-
Passive fit across multiple implants
-
Precise MUA positioning
-
Correct screw channel angulation
-
Balanced occlusion
If the alignment is off, even slightly, it can result in:
-
Tension in the framework
-
Improper seating
-
Screw loosening
-
Long-term mechanical complications
⚙️ Our Verification Process
Before finalizing the design, we:
-
Double-check scan merging accuracy
-
Verify implant axis consistency
-
Confirm MUA library compatibility
-
Cross-reference CBCT and surface scans
Accurate fiducial alignment reduces remakes and ensures long-term stability of the AOX prosthesis.
