Digital Dynamic Occlusal Analysis and Equilibration for Salvage of Compromised Full-Arch Prostheses.

OBJECTIVE

To establish a digitally integrated protocol for managing failed full-arch occlusal rehabilitations through dynamic jaw tracking, virtual occlusal analysis, and computer-guided equilibration.

CLINICAL CONSIDERATIONS: A virtual patient model was reconstructed using multimodal three-dimensional datasets including cone-beam computed tomography, intraoral scans, photographs and jaw motion records. Dynamic occlusal simulations identified premature contact asymmetry, and digital occlusal equilibration evaluated the discrepancy between the initial occlusion and centric relation occlusion. Guided by these findings, intraoral equilibration and computer-aided design/manufacturing (CAD/CAM) transitional restorations were implemented, followed by definitive restorations, eliminating conventional articulator mounting and manual analysis.

CONCLUSIONS

The reintervention protocol for compromised full-arch occlusal rehabilitation achieved biomechanical stability and esthetic harmony via a digital workflow.

CLINICAL SIGNIFICANCE: Digital occlusal analysis and equilibration combined with staged CAD/CAM workflows addresses complex rehabilitation failures by synchronizing functional demands with esthetic parameters, reducing clinical adjustments compared to analog methods. The biologic adaptation phase proved critical for patients with preexisting occlusal dysfunction.
