Bicon种植体在后牙即刻种植的临床应用研究

Study on clinical application of Bicon dental implant in the immediate implantation of posterior teeth

目的:评价Bicon种植体应用于后牙即刻种植的短期临床疗效。方法:2015年1月~2015年8月,选择24例患者共31颗无急性炎症的磨牙,经微创拔牙后彻底清除炎性组织并同期植入Bicon种植体,种植体颈周植入自体骨,术后3~6个月完成冠修复,修复后追踪观察时间为18.6±4.3个月,通过临床、影像学检查以及患者满意度调查来评估Bicon种植体在即刻种植中的治疗效果。结果:31枚种植体在随访期间存留率为100%,修复后1年种植体近、远中边缘骨吸收分别为(0.32±0.41)mm与(0.28±0.34)mm,自修复完成至最后一次复查,全部正常行使功能,患者满意度较高。结论:Bicon种植体应用于后牙区即刻种植近期可获得良好的临床疗效。

Objective：The purpose of this study was to evaluate the short-term clinical outcomes of Bicon dental implants in the immediate implantation for posterior teeth. Methods： 24 patients（31 posterior teeth） with non-acute inflammation to be scheduled for immediate implant were selected to be treated with Bicon dental implants after minimally invasive extraction and removing inflammatory tissue from January, 2015 to August, 2015. Autologous bone was implanted around the neck of the implant. Prostheses were restored after 3 to 6 months. The follow-up time was 18.6 ±4.3 months after the repair. To evaluate the clinical effect of Bicon implants in immediate implantation through clinical and radiological perspectives as well as patient satisfaction surveys. Results： During the follow-up, the survival rate of implants was 100%. The mesio and distal marginal bone loss during the implant is respective（0.32±0.41）mm and（0.28 ±0.34）mm in a year after implantation. All dental implant were in normal function and patient satisfaction was very high. Conclusion： Bicon implants in the immediate implantation of posterior teeth could yield good clinical results in short term.
