Precision in endodontic therapy by novel-guided approach.

Guided endodontics has proven effective in treating pulp canal obliteration (PCO). However, challenges arise when dealing with limited vertical space, particularly in cases where long burs and guides are necessary. In this case report, we introduce a novel approach utilizing a sleeveless three-dimensional (3D)-printed guide, aimed at overcoming vertical space constraints while maintaining visibility and irrigation during drilling.
