The paper reports four cases of tooth transplant: two teeth were transplanted once they were fully mature (completely formed roots) and two were transplanted as germs. Having documented the clinical and radiological recovery for all four teeth, orthodontic braces were applied for a variety of reasons. In the two cases of teeth transplanted once the roots had completely formed it was impossible to move the teeth, whereas in the case of the germ transplants the teeth were quickly moved to a correct occlusal position. On the basis of these different reactions, the author assesses the possibility of histological recovery of the tooth transplant. Repeated radiographic controls showed anomalies in radicular formation and of the camera pulposa. Lastly, the paper discusses the optimal time to transplant a tooth germ.
该论文报告了4例牙齿移植病例：2颗牙齿在完全成熟（牙根完全形成）后进行移植，另外2颗作为牙胚进行移植。记录了所有4颗牙齿的临床和放射学恢复情况后，出于各种原因应用了正畸矫治器。在牙根完全形成后移植的2例病例中，牙齿无法移动，而在牙胚移植的病例中，牙齿很快就移动到了正确的咬合位置。基于这些不同反应，作者评估了牙齿移植组织学恢复的可能性。反复的放射学检查显示牙根形成和髓腔存在异常。最后，该论文讨论了移植牙胚的最佳时机。
