Intrusion of permanent teeth is one of the most severe types of traumatic injuries. Different treatment strategies have been proposed, and the best approach for each case depends on the stage of root development, severity of the intrusive luxation, presence of alveolar fracture and number of intruded teeth. The purpose of this paper is to describe the treatment management of 2 cases of severely intruded immature permanent maxillary central incisors in 7 1/2- and 8-year-old children. In case 1, the traumatized tooth was treated by surgical repositioning, while in case 2 watchful waiting for spontaneous re-eruption was the treatment of choice. Treatment strategies were successful in both cases, as demonstrated by the continuation of root development, maintenance of pulp vitality, and absence of signs of periapical pathosis during the follow-up period. Regardless of the treatment strategy traumatically intruded teeth should undergo periodical clinical and radiographic surveillance on a long-term basis to allow early detection of possible complications.
恒牙嵌入是最严重的创伤性损伤类型之一。已经提出了不同的治疗策略，每个病例的最佳方法取决于牙根发育阶段、嵌入性脱位的严重程度、牙槽骨骨折的存在情况以及嵌入牙齿的数量。本文的目的是描述2例7岁半和8岁儿童严重嵌入的未成熟上颌中切牙的治疗处理。病例1中，受伤牙齿通过手术复位进行治疗，而病例2中，选择密切观察等待自发再萌出。两种病例的治疗策略均成功，在随访期间，牙根继续发育、牙髓活力得以维持且无根尖病变迹象。无论采用何种治疗策略，创伤性嵌入的牙齿都应长期接受定期的临床和影像学监测，以便早期发现可能的并发症。
