Presentation Transcript

  1. 口腔解剖生理学拓展资源 案例库

  2. 案例三 由下颌磨牙髓腔解剖指导开髓 下颌磨牙髓腔形态有什么特点？ 开髓有什么注意事项？

  3. 下颌磨牙髓腔解剖形态 1、髓顶髓底相距较近。 2、舌侧髓角高于颊侧髓角，近中髓角高于远中髓角。 3、牙冠向舌侧倾斜，髓腔偏向颊侧。

  4. 下颌磨牙髓腔解剖形态

  5. 下颌磨牙开髓要点 下颌磨牙牙冠向舌侧倾斜，髓腔偏向颊侧，故开髓部位应在牙合面偏向颊尖处，如果在合面中央开髓尤其是偏向舌侧，会导致舌侧壁薄弱而折断。

  6. 开髓动作

  7. 下颌磨牙开髓洞型

  8. 病例：由于操作不当引起的穿髓
