To present a survival analysis of 133 consecutively placed moderately rough implants, all with a total follow-up of 20 years.
A total of 133 implants of the same brand placed in 46 patients at the same county clinic in Sweden were followed up prospectively over 20 years and analyzed for survival and bone height, the latter evaluated in periapical radiographs.
A total of 7 implants failed, 4 of which were in the same patient. Implant failure was associated with a combination of smoking and bruxism in 5 of the 7 failed cases. A 20-year survival rate of 94.7% was observed. Average marginal bone loss (MBL) at 20 years of follow-up was 0.543 ± 1.193 mm, with 9 implants having more than 2 mm of MBL. A total of 20 patients with 25 implants dropped out of the study; however, if death of the patient is excluded as a dropout reason, only 3 implants in 3 patients were unaccounted for.
Good clinical results in the 95% survival range were observed with moderately rough implants over a 20-year follow-up period.
对 133 枚连续植入的中度粗糙种植体进行生存分析，所有种植体的总随访时间为 20 年。
在瑞典的一个县诊所，对 46 名患者连续植入了 133 枚同种品牌的种植体，前瞻性随访 20 年，对其生存情况和骨高度进行分析，后者通过根尖片评估。
共有 7 枚种植体失败，其中 4 枚来自同一位患者。在 7 例失败病例中，有 5 例与吸烟和磨牙症有关。观察到 20 年的存活率为 94.7%。20 年随访时平均边缘骨吸收（MBL）为 0.543±1.193mm，9 枚种植体的 MBL 超过 2mm。共有 20 名患者（25 枚种植体）退出研究；然而，如果将患者死亡排除为退出原因，则只有 3 名患者的 3 枚种植体未被计入。
在 20 年的随访中，观察到中度粗糙种植体的临床效果良好，存活率在 95%范围内。
