Traumatic injuries caused by intrusion account for 4-22% of the damage in anterior primary teeth and are generally related to axial impact. They are more frequent in children aged 1-3 years because of the additional high resilience and flexibility of the primary teeth supporting structures. The treatment decision will depend on the magnitude of the trauma and on the displacement position. In most cases, radicular displacement occurs towards the labial bone plate. The clinical decision of spontaneous re-eruption and observation were adopted. This study aims at presenting a literature review illustrated with two case reports of patients having intrusive luxation injuries of the primary incisors.
因嵌入导致的创伤性损伤占乳前牙损伤的4%-22%,通常与轴向撞击有关。由于乳牙齿支持结构具有额外的高弹性和柔韧性,此类损伤在1-3岁儿童中更为常见。治疗决策将取决于创伤的严重程度和移位位置。在大多数情况下,牙根向唇侧骨板移位。采用了自然再萌出和观察的临床决策。本研究旨在通过两例乳切牙嵌入性脱位损伤患者的病例报告进行文献综述。
