Replace种植系统在即刻种植中的临床应用研究

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。

Clinical application of Replace implant system in the immediate implantation

Objective：To evaluate the clinical effect of Replace implant system in application of the immediate implantation.Method：The Replace implant system was implanted in 28 patients who adapted to immediate implantation during February in 2006 to February in 2008.The dental implant rehabilitation was administered 3-6 months after the implant surgery in accordance to the clinical and radiographic parameters.The clinical effect was followed up over 18～36 months（average 15 months）.Result：45 of all the 47 implants were successive and without obvious complication in the follow-up period,the absorption level of alveolar bone was less than 1mm in the first year after rehabilitation.2 implants embedded in the patient with diabetes dropped 7 weeks after the rehabilitation.The success rate was 95.74 %（45/47）.There were 4 implants involved with peri-implant mucositis and 2 metal-porcelain full crowns yielded ceramic chipping.Conclusion：Immediate implantation with the Replace system could shorten the anodontia time and slow down the absorption pace of alveolar bone.Patients were highly satisfied with the immediate implantation,However,the indication must be controlled strictly.
