Deducing a surgical dilemma using a novel three dimensional printing technique.

Area of Science:

• Dentistry
• Endodontics
• Biomedical Engineering

Background:

• Persistent apical periodontitis often necessitates surgical intervention when conventional endodontic retreatment is unsuccessful.
• Accurate diagnosis and meticulous planning are crucial for surgical success, especially when lesions approach vital anatomical structures.

Observation:

• A case of persistent apical periodontitis associated with tooth 16, located near the maxillary sinus, was surgically managed.
• Fused deposition modeling-based three-dimensional (3D) printed models were utilized for enhanced patient education and precise surgical planning.
• The surgical procedure involved lesion enucleation, apicectomy of specific roots, and retro-filling with mineral trioxide aggregate.

Findings:

• The use of 3D printed models facilitated a better understanding of the lesion's extent and its relationship with the maxillary sinus.
• The surgical intervention led to symptom resolution, allowing for the subsequent fabrication and cementation of a full coverage metal crown.

Implications:

• Three-dimensional printing technology offers a valuable adjunct in endodontic surgery, enhancing visualization and planning.
• Integrating 3D printing with established endodontic principles can lead to more predictable and successful surgical outcomes.
• This approach holds promise for managing complex endodontic pathologies adjacent to critical anatomical structures.
