Microdimensioned osteosynthesis using miniplates has been common practice in maxillofacial surgery. However, tooth injury during the application of the miniplates have been reported in few papers. In this case, a 32-yr-old female patient, whose two teeth were necrosed because of the perforation during screw insertion was presented. The reason of the perforations during the rigid internal fixation was the lack of radiographic assessment because of the pregnancy. Maxillary right first premolar and maxillary left canine were perforated and necrosed because of the screw insertion. The necrosed teeth were detected 1 yr after the rigid internal fixation. The root canals of nonvital teeth were filed using step-down approach. Cold lateral condensation of gutta-percha was used to fill the canals. Six-month recall visits were scheduled and there was no problem after 2-yr follow-up period.
使用微型钢板进行微尺寸骨合成在颌面外科中是常见的做法。然而，关于微型钢板应用过程中牙齿损伤的报道很少。在此病例中，报告了一名32岁女性患者，其两颗牙齿因螺钉植入过程中的穿孔而坏死。坚固内固定过程中发生穿孔的原因是由于患者怀孕而缺乏影像学评估。上颌右侧第一前磨牙和上颌左侧尖牙因螺钉植入而穿孔并坏死。坚固内固定1年后发现坏死牙齿。对无活力牙齿的根管采用逐步深入法进行锉治。采用冷侧向加压法用牙胶充填根管。安排了6个月的复诊，2年随访期后未出现问题。
