目的：探讨牙齿外伤后种植牙即刻修复的效果。方法：前牙区牙齿外伤患者68例（100颗）随机分为治疗组与对照组各50颗，对照组采用延期种植，治疗组采用即刻种植。观察2组留存率和预后。结果：对照组的留存率为98．0％，治疗组为100．0％，组间对比差异无统计学意义（ P＞0．05）。术后3个月随访进行观察，治疗组的周围牙槽骨吸收高度明显低于对照组，对比差异有统计学意义（P＜0．05）。结论：牙齿外伤后种植牙即刻修复并不降低留存率，但是能有效减少牙槽骨吸收高度，从而改善预后，值得推广应用。

Objective:To explore the Clinical efficiency of immediate implantation after traumatic dental injury.Methods:100 cases with traumatic dental injury were randomly divided into treatment group and control group with 50 cases.Control group were given de-layed implant, Treatment group were given immediate implant.The retention rate and prognosis were observed.Results:The retention rate of control group (98%) and treatment group (100%) showed no statistical difference (P>0.05).After 3 months follow-up, alveolar bone absorption height of treatment group was lower than control group, The difference was statistically significant (P>0.05). Conclusions:Immediate implantation after traumatic dental injury doesn't affect retention rate, but do decrease the alveolar bone absorp-tion height, improve the prognosis, worth clinical promotion.
