CBCT-guided and 3D Printing-assisted Endodontic Management of Severe Pulp Canal Obliteration in Anterior Teeth: A Report of Two Cases
Grisel Virgen Pérez, Miyuki Nonaka Nava, Elan Ignacio Flores OrozcoBackground/Purpose
Pulp canal obliteration (PCO) represents a significant challenge in endodontics because canal location is frequently associated with a high risk of perforation, excessive dentin removal, and other procedural complications. Static-guided endodontics integrates cone-beam computed tomography (CBCT), intraoral scanning, digital planning, and three-dimensional printing to facilitate accurate and conservative access to calcified root canals. This report describes the management of two anterior teeth with severe PCO using a static-guided endodontic approach.
Case Report
Two patients presenting with severe PCO and symptomatic apical periodontitis were treated using static-guided endodontics. CBCT and intraoral scan data were merged through digital planning software to design and fabricate customized endodontic guides. Guided access enabled precise localization of the residual canal lumen and conservative dentin removal in both cases. Root canal treatment was completed without additional procedural complications. Clinical and radiographic follow-up at 6 months demonstrated absence of symptoms and favorable periapical healing.
Conclusion
Static-guided endodontics appears to be a feasible and minimally invasive approach. The integration of CBCT, digital planning, and three-dimensional printing facilitates canal localization, preserves tooth structure, and may reduce the risk of iatrogenic complications.
