目的:评价Anthogyr种植体应用于后牙区即刻种植的近期临床效果。方法:2013年1月~2014年11月施行后牙区即刻种植手术患者67名,共103个种植位点,均为微创拔牙后即刻植入Anthogyr种植体,其中67枚种植体同期行GBR技术,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6~15个月(平均9个月)。结果:共植入103枚种植体,其中101枚骨结合良好,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枚种植体于种植手术后20周脱落,成功率为98.06%。结论:Anthogyr种植体在后牙区采用即刻种植可以获得良好的骨结合,缩短患者缺牙时间,减缓牙槽嵴吸收,患者满意度较高。
OBJECTIVE: To evaluate the near-term clinical outcome of Anthogyr implants for immediate implant in posterior teeth. Methods: From January 2013 to November 2014, 67 patients undergoing immediate dental implant surgery in 103 posterior implant sites were all underwent implantation of Anthogyr implants immediately after tooth extraction. Sixty-seven implants were implanted with GBR Technique. According to the clinical and radiographic findings, the patients underwent surgery and superstructure repair 3 to 6 months after operation. The patients were followed up for 6 to 15 months (mean, 9 months). Results: A total of 103 implants were implanted. Among them, 101 had good bone union with no obvious complications during the follow-up period. The level of alveolar bone resorption was less than 1 mm in the first year after implant placement. One patient with diabetes mellitus and two implants slipped off 20 weeks after operation, with a success rate of 98.06%. Conclusion: Anthogyr implants with immediate implant in the posterior teeth area can achieve good bone union, shorten the time of tooth loss and reduce the alveolar ridge absorption, and patients’ satisfaction is high.
