Intrusion is the most severe luxation injury type, which results in both soft and hard tissue damage. In severe intrusions, the crown must be re-positioned in the arch to avoid periapical pathology and marginal bone loss. There is minimal information about the effect of treatment delay on pulpal and periodontal healing in intrusion trauma. The present paper reports on two cases of severe intrusive luxation applied late at different times treated with surgical extrusion. The first patient, an 11-year-old female, referred to Tokat GOP pediatric dentistry clinic three days after the intrusion tooth 21. The second patient, a 13-year-old male, referred to our clinic fifteen days after a traffic accident. The intruded teeth were positioned surgically and splinted. Surgical extrusion should be preferred as soon as possible to initiate root canal treatment in teeth, the crown of which is fully embedded in the alveolar bone.
嵌入是最严重的脱位损伤类型，会导致软硬组织损伤。在严重嵌入的情况下，必须将牙冠重新定位到牙弓中，以避免根尖病理和边缘骨丧失。关于治疗延迟对嵌入性外伤中牙髓和牙周愈合的影响，信息很少。本文报告了两例外伤性严重嵌入，分别在不同时间应用外科牵出术进行治疗。第一例患者为 11 岁女性，外伤后 21 牙嵌入 3 天后到托卡特 GOP 儿科牙科诊所就诊。第二例患者为 13 岁男性，因交通事故后 15 天到我院就诊。将嵌入的牙齿进行手术复位并固定。对于完全嵌入牙槽骨的牙冠，应尽快进行外科牵出术，以便进行根管治疗。
