This is a comprehensive, long-term follow-up study of single-implant treatments. At the Brånemark Clinic in Gothenburg, Sweden, during the period of 1982-1985, 16 patients received single-tooth implants.
This study evaluates the survival rate of the implants after nearly four decades, focusing on the biological and technical complications.
Of the original 16 patients with a total of 23 implants, 13 patients with 18 implants were available for the follow-up and were included in the study. Clinical and radiographic examinations were performed on these patients.
The cumulative survival rates were 95.6% for the implants and 60.9% for the implant-supported crowns after 38-40 years in function. The marginal bone level changes were 0.9 ± 1.0 mm (range, -0.5─3.0 mm) over the follow-up period. The frequency of biological complications was low; although mucositis was common, no cases of peri-implantitis were observed. The mean plaque index was 16.9% ± 11.6% (range, 1%─34%) and the mean probing depth around the implants was 3.8 ± 2.2 mm (range, 0.0─7.0 mm). Few technical complications were observed, although many of the original implant-supported crowns had been replaced for esthetic reasons.
The findings emphasize the importance of long-term follow-up in implant dentistry, particularly for younger patients, to improve understanding of potential complications and the longevity of treatment outcomes. Overall, single-tooth implants have a favorable long-term prognosis, though crown replacement may eventually be necessary.
这是一项关于单颗种植体治疗的全面长期随访研究。1982年至1985年期间，在瑞典哥德堡的布兰emark诊所，16名患者接受了单颗牙齿种植。
本研究评估了近四十年来种植体的存活率，重点关注生物学和技术并发症。
在最初的16名共有23颗种植体的患者中，13名有18颗种植体的患者可供随访并纳入研究。对这些患者进行了临床和影像学检查。
在功能使用38 - 40年后，种植体的累积存活率为95.6%，种植体支持的牙冠累积存活率为60.9%。随访期间边缘骨水平变化为0.9±1.0毫米（范围为 - 0.5至3.0毫米）。生物学并发症的发生率较低；虽然粘膜炎很常见，但未观察到种植体周围炎病例。平均菌斑指数为16.9%±11.6%（范围为1%至34%），种植体周围的平均探诊深度为3.8±2.2毫米（范围为0.0至7.0毫米）。虽然许多最初的种植体支持牙冠因美观原因已被更换，但观察到的技术并发症很少。
研究结果强调了种植牙科长期随访的重要性，特别是对于年轻患者，以增进对潜在并发症和治疗效果持久性的理解。总体而言，单颗牙齿种植体具有良好的长期预后，尽管最终可能需要更换牙冠。
