Two documented cases involving avulsions of an incisor and a cuspid are reported. Long-term observations following replantations indicated factors in addition to those reported in Part 1 of this study. Endodontic metallic implants may retard the intrusive process. A fixed-bridge splint also appears to have retarded the ankylosis phenomenon. The three case reports in the two parts of this study indicated that splint time may not be a critical factor in the prognosis of replanted teeth. Calcium hydroxide failed to prevent early root resorption and eventual ankylosis in an early replantation case; the other two cases, with longer replant time, fared better without calcium hydroxide. Endodontic treatment of avulsed teeth soon after replantation is suggested; a time period of several weeks does not appear critical to the prognosis. Removal of the apical root segment prior to replantation does not appear to affect the replacement root resorption process. The reporting of long-term documented cases should be encouraged in order that replantation techniques may be evaluated.
报告了两例涉及门牙和尖牙撕脱的病例。再植后的长期观察表明，除了本研究第1部分所报告的因素外，还有其他因素。牙髓金属植入物可能会延缓牙齿嵌入过程。固定桥夹板似乎也延缓了牙齿粘连现象。本研究两部分中的三个病例报告表明，夹板固定时间可能不是再植牙预后的关键因素。在一例早期再植病例中，氢氧化钙未能预防早期牙根吸收和最终的牙齿粘连；另外两例再植时间较长的病例，未使用氢氧化钙情况较好。建议再植后尽快对脱位牙进行牙髓治疗；几周的时间对预后似乎并不关键。再植前去除根尖根段似乎不影响替代牙根的吸收过程。应鼓励报告长期有记录的病例，以便对再植技术进行评估。
