目的:探讨应用CDIC一段式种植体改制成残根种植体即刻修复前牙残根的临床效果。方法:前牙残根的患者29名,随机分成2组,实验组15人,对照组14人。实验组利用残根植入残根种植体,对照组常规拔牙即刻种植。比较2组术后的临床疗效。结果:实验组患者畏惧率及肿胀率低于对照组,差异具有统计学意义。实验组种植体的初期稳定性优于对照组。2组疼痛率差异无统计学意义。结论:残根种植体植入后具有非常好的初期稳定性,术后并发症轻微,患者易于接受,近期疗效满意。
Objective: To investigate the clinical effect of using CDIC one-stage implants remodeling into residual root implants to repair anterior residual roots immediately. Methods: Twenty-nine patients with anterior teeth residual root were randomly divided into two groups, 15 in the experimental group and 14 in the control group. In the experimental group, the residual root was implanted in the residual root and the control group was implanted immediately. The clinical effects of the two groups were compared. Results: The fear rate and swelling rate of the experimental group were lower than those of the control group, the difference was statistically significant. The initial stability of experimental group was better than that of control group. There was no significant difference in pain rate between the two groups. Conclusion: The residual root implants have very good initial stability after implantation. The postoperative complications are mild and the patients are easy to accept. The short-term curative effect is satisfactory.
