摘　　要：当对倾斜、伸长及扭转等特殊情况的牙齿进行牙体预备时,进行牙齿形态的数字化设计并制作多级三维打印导板指导牙体预备是一种更加高效、准确的方案。本文报道了1例上下颌尖牙倾斜角度大、伸长明显且伴扭转采用冠修复改形的病例,以目标修复体空间分析技术为指导,先根据修复体的最终形态设计制作截冠导板指导截冠,再设计制作牙体预备导板指导备牙,上述多级导板的联合应用提高了特殊情况时牙体预备的效率和准确性,具有很好的临床应用前景。In clinical dentistry,addressing unique conditions such as tilted,elongated,and torsion teeth during preparation can be effectively managed through digital tooth morphology design.The production of a multi-stage 3D-printed guide offered a more efficient and accurate solution.This article presented a case of significant inclination,elongation,and torsion in the maxillary and mandibular canines that were successfully treated using crown restoration modification.A crown preparation guide was fabricated based on the final form design of the restoration using the target restorative space analysis technique to ensure precise tooth preparation.A tooth preparation guide was also designed and utilized further to enhance accuracy and efficiency during complex tooth preparation.The combined application of these multi-stage guides demonstrated promising clinical prospects.
