BACKGROUND
Guided Endodontics is suggested as a reliable method for management of teeth with pulp canal obliteration (PCO). The guide used for this usually involves multiple teeth to gain stability but is bulky. It is therefore suboptimal to be used along with rubber dam.
AIM
To describe the use of a minimized single-tooth guide template in three patients with radiographic evidence of PCO.
DESIGN
The template was designed and fabricated using the cone-beam computed tomography (CBCT) scan and a surface scan image of the involved teeth. In all three patients, the root canals were successfully negotiated within 15 minutes, with the template involving only the tooth in focus or with neighboring half of the teeth. The operator stabilized the template if required.
CONCLUSIONS
This case series shows clinically that successful outcome can be obtained during guided endodontics with the use of a single-tooth template in previously traumatized anterior teeth with PCO.
背景
有研究表明，牙髓腔钙化根管导向预备（Guided Endodontics）是治疗牙髓腔钙化（Pulp Canal Obliteration，PCO）牙齿的可靠方法。用于该方法的导板通常需要涉及多颗牙齿以获得稳定性，但体积较大。因此，与橡皮障一起使用并不理想。
目的
描述在 3 名有 PCO 放射影像学证据的患者中使用简化的单颗牙导板的情况。
设计
使用锥形束 CT 扫描（Cone-beam Computed Tomography，CBCT）和受累牙齿的表面扫描图像设计和制作模板。在所有 3 名患者中，均在 15 分钟内成功预备根管，模板仅涉及焦点牙或相邻半颗牙。如果需要，操作员会稳定模板。
结论
本病例系列研究表明，在前牙外伤伴 PCO 的患者中，使用单颗牙模板进行牙髓腔钙化根管导向预备，可以获得成功的临床效果。
