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. A 22-year-old male patient presented with intermittent pain around tooth #21, diagnosed with pulp necrosis and symptomatic apical periodontitis. Employing the sleeveless 3D-printed guide alongside a long neck carbide bur, we achieved a minimally invasive access cavity up to the root canal. This technique presents a promising alternative to conventional guided endodontic approaches, particularly beneficial in cases of PCO.
引导式牙髓治疗已被证明在治疗牙髓腔闭塞（PCO）方面有效。然而，在处理有限的垂直空间时会出现挑战，特别是在需要使用长车针和导板的情况下。在本病例报告中，我们介绍了一种利用无袖三维（3D）打印导板的新方法，旨在克服垂直空间限制，同时在钻孔过程中保持视野和冲洗。一名22岁男性患者因21号牙周围间歇性疼痛就诊，诊断为牙髓坏死和症状性根尖周炎。使用无袖3D打印导板和长颈硬质合金车针，我们成功地在根管上方制备了一个微创进入腔。该技术为传统引导式牙髓治疗方法提供了一种有前景的替代方案，尤其在PCO病例中具有优势。
