Delayed replantation of an avulsed tooth may result in rapid root resorption or, more frequently, dental ankylosis with subsequent bone substitution. If this process develop slowly, it is possible to observe that tooth loss is characterized by a well conserved alveolus with regard to bone preservation, particularly in vertical dimension. This clinical case reports a dental trauma of a central incisor in a young boy characterized by tooth avulsion and its delayed replantation. After 10 years, dental ankylosis of the incisor was recorded and the patient underwent a prosthetic-orthodontic rehabilitation using CAD-CAM technology and no-prep veneers.
外伤性脱位牙的再植如果延迟，可能会导致快速的牙根吸收，或者更常见的是，牙齿发生骨性粘连，随后被骨质替代。如果这个过程发展缓慢，就有可能观察到牙齿缺失的牙槽骨保存情况良好，特别是在垂直方向。本临床病例报告了一名年轻男孩的中切牙外伤，表现为牙齿脱位及其延迟再植。10 年后，该切牙发生骨性粘连，患者采用 CAD-CAM 技术和不备牙贴面进行了修复-正畸治疗。
