目的:评价Replace种植系统应用于即刻种植的临床效果。方法:收集2006年2月~2008年2月期间具有即刻种植适应症的28例患者,行Replace种植系统植入术,术后3~6个月根据临床和影像学结果行二期手术及上部结构修复,随访观察18~36个月(平均15个月)。结果:共植入47枚种植体,其中45枚获得成功,在随访期内无明显并发症,种植体负重后第1年牙槽骨吸收水平<1 mm。1例糖尿病患者2枚种植体于二期修复后7周脱落,成功率为95.74%(45/47)。种植体周围龈炎4枚,烤瓷冠崩瓷2枚。结论:Replace即刻种植可缩短患者缺牙时间,减缓牙槽嵴吸收,患者满意度较高,但必须严格掌握适应症。
PURPOSE: To evaluate the clinical effectiveness of Replace implant system for immediate implant. METHODS: Twenty-eight patients with immediate implantable indications from February 2006 to February 2008 were enrolled in the Replace implant system. According to the clinical and radiographic findings, two to three surgeries and upper three to six months postoperatively were performed. Structural repair, follow-up observation of 18 to 36 months (an average of 15 months). Results: A total of 47 implants were implanted, of which 45 were successful. No significant complications were observed during the follow-up period. The level of alveolar bone resorption in the first year after implant placement was less than 1 mm. One patient with diabetes mellitus and two implants were shed at 7 weeks after the second phase repair, with a success rate of 95.74% (45/47). 4 gingivitis around the implant, porcelain crown collapse porcelain 2 pieces. Conclusion: Replace immediate implant can shorten the time of patients with missing teeth, reduce alveolar ridge absorption, patients with higher satisfaction, but must be strictly controlled indications.
