Six cases of vertical root fractures accompanied by vertical bone loss are presented. Possible causes for these fractures are suggested. Four vertical fractures probably resulted from the use of excessive pressure at the time of obturation of the canals. One vertical root fracture may have been caused by the cementation of a post, and another may have been caused by the cementation of an inlay in an endodontically treated tooth. All of the fractures resulted in alveolar bone loss to the apical extent of the fracture lines. The definitive treatment in each case was extraction of the tooth or root amputation. In one case successful treatment was accomplished by apically positioning the flap.
本文报告6例伴有垂直性骨吸收的牙根纵裂病例，并提出这些骨折的可能原因。4例垂直性骨折可能是由于根管充填时使用了过大的压力所致。1例垂直性牙根骨折可能是由于桩核粘固引起的，另1例可能是由于牙髓治疗后牙齿嵌体粘固所致。所有骨折均导致牙槽骨吸收至骨折线的根尖范围。每例的最终治疗方法是拔牙或牙根切除术。1例通过根尖瓣定位成功完成了治疗。
