Diagnostic-Oriented Full-Arch Implant Rehabilitation: A Clinical Case Report Based on the 1st Global Consensus for
Purpose:
To illustrate how the structured 1st Global Consensus for Clinical Guidelines (GCCG 2026) diagnostic recommendations translate into clinical practice in a complex, anatomically asymmetric case.
Materials And Methods:
A 50-year-old man with maxillary edentulism secondary to stage IV generalized periodontitis underwent a GCCG-aligned diagnostic workflow: facial analysis, per-quadrant full-arch classification, flangeless try-in for preprosthetic ridge assessment, and dual-scan CBCT for prosthetically driven planning. Per-quadrant classification identified a case with anatomical asymmetry (Class II, first quadrant; Class IV, second quadrant), confirming an FP3 design and a quadrant-differentiated surgical strategy.
Results:
The structured diagnostic workflow enabled convergent, evidence-based decisions at every stage. Preprosthetic diagnosis established FP3 necessity and validated lip support. The dual-scan protocol supported prosthetically driven pilot-guided surgery. Definitive monolithic zirconia prostheses were delivered with verified passive fit at 6 months.
Conclusions:
The GCCG 2026 diagnostic framework is directly applicable in anatomically asymmetric edentulous maxilla cases. Per-quadrant assessment and preprosthetic diagnosis determined all downstream clinical decisions.
