Abstract

Purpose: To retrospectively evaluate peri-implant bone loss and health status associated with the long-term use of laser surface-treated implants.

Methods: For control study, total of 23 titanium ASTM F136 grade 23 implants were placed in the edentulous molar area of the mandible. When the Implant Stability Quotient (ISQ) ≥ 70 and insertion torque value (ITV) ≥ 35-50 Ncm at the insertion site, an immediate provisional restoration was connected to the implant within a week after surgery. The definitive restorations were placed 2 months after surgery for all implants. 13 implants were immediately loaded, while 10 implants were conventionally loaded. For comparative study, Radiographs were taken from third years for and then annually for the subsequent eight years to monitor marginal bone loss.

Results: After eight year of implant installation, the average change in vertical bone loss was 0.009 mm (P < 0.001), while the average change in horizontal bone loss 8 year after implant placement was 0.026 mm (P < 0.001). The mean marginal bone loss was < 0.2 mm on average.

Conclusions: In this retrospective study, laser-treated implants exhibit a low rate of bone absorption around the implants.

关于激光表面处理种植体临床效果的八年回顾性研究。

目的：回顾性评估与长期使用激光表面处理种植体相关的种植体周围骨质流失和健康状况：方法：在对照研究中，在下颌无牙臼齿区植入 23 个 ASTM F136 等级 23 的钛种植体。当种植体稳定性商数（ISQ）≥70，插入部位的插入扭矩值（ITV）≥35-50 Ncm时，在术后一周内将临时修复体连接到种植体上。所有种植体均在术后 2 个月植入最终修复体。13 个种植体采用即刻负重法，10 个种植体采用传统负重法。为了进行比较研究，我们从种植体植入后的第三年开始拍摄X光片，之后的八年每年拍摄一次，以监测边缘骨质流失情况：结果：种植体安装八年后，垂直骨质流失的平均变化量为 0.009 毫米（P 结论：种植体安装八年后，垂直骨质流失的平均变化量为 0.009 毫米（P）：在这项回顾性研究中，经过激光处理的种植体周围骨吸收率较低。
