| ［摘要］ 目的 探讨全口义齿压迫导致三叉神经痛的病因及机制。方法 对5例佩戴全口义齿继发三叉神经痛的患者拍摄锥形束CT，发现颏孔区牙槽脊完全吸收，颏孔暴露，将颏孔区黏膜对应的基托组织面进行调磨，并且磨除该区域由于牙槽嵴吸收造成的义齿过长的边缘，若疼痛无缓解，重新制作义齿，颏孔区充分缓冲。结果 1例经过第2次义齿调磨后，三叉神经痛消失。2例通过5次调磨后症状消失。2例经过重新制作义齿，颏孔区充分缓冲后，症状消失。结论 下颌牙槽嵴加速吸收后，颏孔暴露，颏部三叉神经及其分支颏神经受到义齿压迫，引起疼痛。该区域压力及刺激解除后，疼痛消失。 |

| Abstract: |
| ［Abstract］ Objective To investigate the etiology and mechanism of trigeminal neuralgia caused by compression of complete denture. Methods Cone-beam computed tomography was performed on 5 patients with trigeminal neuralgia caused by wearing complete dentures and the results showed that the alveolar ridge in the mental foramen area was completely absorbed and the mental foramen was exposed. The corresponding basal tissue surface of the mucosa in the mental foramen area was adjusted and ground, and the overlong edge of the dentures caused by alveolar ridge absorption in this area was removed. If the pain was not relieved, the dentures should be rebuilt and the mental foramen area should be fully cushioned. Results Trigeminal neuralgia disappeared in 1 case after the second grinding of the denture. The symptoms disappeared in 2 cases after 5 times of grinding. The symptoms disappeared in 2 cases after the dentures were made again and the mental foramen area was fully buffered. Conclusion After accelerated absorption of alveolar ridge of mandible, the mental foramen is exposed. The trigeminal nerve and its branches in the mental region are compressed by dentures, causing pain. After the pressure and stimulation in this area are relieved, the pain disappears. |
