Traumatic intrusion of permanent teeth is a relatively infrequent but serious type of dental injury, due to the complicated picture it involves. Various treatment approaches have been suggested, so far, regarding management of intrusive luxation. Techniques aiming to reposition the intruded tooth include observation for spontaneous reeruption, surgical as well as orthodontic repositioning. However, development of complications such as pulp necrosis, inflammatory root resorption, replacement resorption and ankylosis and loss of marginal bone support makes selection of the most favorable technique controversial. In this paper, a critical review of the existing treatment modalities is attempted and treatment approaches based on diagnostic parameters that are indicative of the severity of an intrusive injury are presented. Recommendations are made after taking into consideration experimental and clinical study findings and observations from other author's and our own clinical experience. Two cases of intrusive luxation in children are presented and management of the dental injuries as well as the complications which occurred are being discussed.
恒牙外伤性嵌入是一种相对少见但严重的牙损伤类型，因其涉及的情况复杂。迄今为止，针对嵌入性牙脱位的处理已提出了各种治疗方法。旨在将嵌入牙复位的技术包括观察其自然萌出、手术复位以及正畸复位。然而，诸如牙髓坏死、炎性牙根吸收、替代性吸收、牙 ankylosis 以及边缘骨支持丧失等并发症的发生使得选择最有利的技术存在争议。本文试图对现有的治疗方式进行批判性综述，并提出基于指示嵌入性损伤严重程度的诊断参数的治疗方法。在考虑实验和临床研究结果以及其他作者的观察结果和我们自己的临床经验后提出了建议。本文还介绍了两例儿童嵌入性牙脱位病例，并讨论了牙损伤的处理以及所发生的并发症。
