牙髓钙化造成的根管狭窄或堵塞显著增加了根管治疗难度,随着数字化技术的快速发展,开髓定位导板技术已经开始在牙体牙髓病学领域应用,为钙化根管治疗提供了新型治疗模式,其在显著降低钙化根管治疗并发症发生率的同时,也提高了治疗成功率。本文报道2 例锥形束CT(CBCT)结合数字化3D导板辅助上前牙根管重度钙化治疗病例,为类似病例的治疗提供参考。

Pulp canal calcification,which leads to root canal narrowing or obstruction,significantly increases the difficulty of root canal treatment. With the rapid development of digital technologies,3D-printing guides have been introduced in the endodontics field,offering a novel treatment approach for severely calcified root canals. This technique reduces the incidence of complications associated with access preparation,orifice location and canal negotiation,thereby improving the treatment success rates. This article reports two maxillary left incisors with severely calcified canals treated with the aid of cone-beam computed tomography(CBCT)combined with 3D-printing guides,so as to provide a reference for similar clinical scenarios.
