PURPOSE
The aim of this study was to compare marginal bone loss around early-loaded SLA and SLActive tissue-level implants (Straumann Dental Implants; Institut Straumann AG, Basel, Switzerland) after a mean of 81-month follow-up period.
MATERIAL AND METHODS
One hundred seven SLA and 68 SLActive implants were placed in 55 patients and loaded with final restoration after 8 and 3 weeks of healing time, respectively. Marginal bone loss around implants was determined radiographically at initial and after a mean observation time ranging between 20 and 81 months. The effect of location (mandible vs maxilla), smoking habit, sex, implant length and diameter, and the type of prosthesis on the marginal bone loss was evaluated.
RESULTS
The overall cumulative survival rate was 98.2% being 99% for SLA implants and 97% for SLActive implants. After 20-month follow-up period, mean marginal bone loss values for the SLA and SLActive implants were 0.24 and 0.17 mm, respectively. After 81 months, mean marginal bone loss for the SLA and SLActive implants reached 0.71 and 0.53 mm, respectively. Marginal bone loss was affected by the length and type of implant and patients' smoking habit after a mean observation time of 20 months. However, none of the parameters had any significant effect on the marginal bone loss after a follow-up period of 81 months.
CONCLUSION
With both SLA and SLActive implants, successful clinical results could be achieved up to 6.5 years of follow-up period.
目的
本研究旨在比较早期负载 SLA 和 SLActive 组织水平种植体（Straumann Dental Implants；Institut Straumann AG，巴塞尔，瑞士）在平均 81 个月的随访期后的边缘骨丧失。
材料和方法
55 名患者共植入 107 个 SLA 和 68 个 SLActive 种植体，分别在 8 周和 3 周的愈合时间后用最终修复体加载。在初始和平均观察时间为 20 至 81 个月之间，通过放射照相确定种植体周围的边缘骨丧失。评估了位置（下颌骨与上颌骨）、吸烟习惯、性别、种植体长度和直径以及假体类型对边缘骨丧失的影响。
结果
总体累积生存率为 98.2%，SLA 种植体为 99%，SLActive 种植体为 97%。在 20 个月的随访期后，SLA 和 SLActive 种植体的平均边缘骨丧失值分别为 0.24 和 0.17 毫米。在 81 个月后，SLA 和 SLActive 种植体的平均边缘骨丧失值分别达到 0.71 和 0.53 毫米。在平均观察时间为 20 个月后，种植体的长度和类型以及患者的吸烟习惯会影响边缘骨丧失。然而，在随访 81 个月后，这些参数对边缘骨丧失均无显著影响。
结论
对于 SLA 和 SLActive 种植体，在长达 6.5 年的随访期内，可以获得成功的临床结果。
