Thirty-two cases of vertical fractures were studied in an attempt to identify the causes and diagnostic signs normally present. In all of the patients except two, osseous defects were present and could be probed. The majortiy (65.63 percent) had only mild pain or a dull discomfort. Seventy-five percent showed diffuse widening of the periodontal ligament space. This study suggests that excessive force during lateral condensation of the gutta-percha caused 84.38 percent of the fractures. A secondary cause was the forcing or tapping of inlays or dowels into place. The majority (78.13 percent) of the patients were over the age of 40. In all but nine of the cases, treatment consisted of the extraction of the involved teeth.
对32例垂直骨折病例进行了研究，试图确定其常见病因及诊断体征。除2例患者外，所有患者均存在骨缺损且可被探及。大多数患者（65.63%）仅有轻微疼痛或隐痛不适。75%的患者表现为牙周膜间隙弥漫性增宽。该研究表明，牙胶侧向加压时用力过大导致了84.38%的骨折。第二个原因是嵌体或桩钉就位时的强行用力或敲击。大多数患者（78.13%）年龄超过40岁。除9例外，所有病例的治疗均包括拔除患牙。
