摘要/Abstract

摘要： 目的评价SLA表面种植体固定修复牙列缺损的8年临床应用效果。方法对130例在烟台市口腔医院种植科要求种植修复牙列缺损的患者,植入SLA表面处理种植体191颗,定期临床及放射学检查,记录种植体存留率、成功率、种植体周围软、硬组织状况及上部结构的稳定性。采用SPSS 17.0软件包对数据进行统计学分析。结果24例患者的31颗种植体失访,1颗种植体在术后5个月时因松动取出, 4颗种植体出现种植体周围炎,种植体失访率、存留率、成功率分别为18.46%、 99.38%和96.88%。种植成功的155颗种植体,8年内未出现明显的生物学并发症,种植体边缘骨吸收平均为（1.34+0.52）mm。8年内共25颗种植体出现螺丝松动、冠脱落、崩瓷、种植体折断等机械性并发症,修复体成功率为83.87%。结论SLA表面种植体不仅能够达到较好的骨结合,而且种植体周围软组织及上部结构能够长期保持健康稳定的状态,临床应用效果较好。

Abstract: To evaluate the clinical effect of titanium implants with SLA surface preparation for partial prostheses. METHODS: One hundred and ninety-one implants with SLA surface preparation were implanted in 130 patients with dentition defect who required dental repair at Yantai Stomatologic Hospital Implant Center. Successful rate of the implant, changes of soft and hard tissue around the implants as well as the stability of the superstructure were recorded and evaluated by regular clinical and X-ray examinations. Data analysis was performed using SPSS 17.0 software package. RESULTS: Twenty four patients with 31 implants were lost to follow up, one implant which loosened 1 week after operation was extracted. Four implants were found with peri-implantitis. The dropout rate, survival rate and successful rate was 18.46%, 99.38% and 96.88%, respectively. No obvious biological complications were observed in 155 successful implants during the observation period. Eight years later, the marginal bone resorption reached to (1.34±0.52) mm. After 8 years, a total of 25 implants had mechanical complications, including superstructure screw mobility, falling off of the crown, porcelain fracture of restorations, implant fracture and the prosthesis success rate was 83.87%. CONCLUSIONS: SLA surface implant can not only achieve good bone integration, but also long-time maintainanance of the soft tissue around the implant and implant superstructure at a healthy and stable state,the clinical effect is better than other dental implants.
