To retrospectively evaluate peri-implant bone loss and health status associated with the long-term use of laser surface-treated implants.
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.
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.
In this retrospective study, laser-treated implants exhibit a low rate of bone absorption around the implants.
回顾性评估长期使用激光表面处理种植体的种植体周围骨丢失和健康状况。
在本对照研究中，总共在无牙下颌磨牙区植入 23 枚钛 ASTM F136 23 级种植体。当种植体稳定性指数（ISQ）≥70 且种植部位的插入扭矩值（ITV）≥35-50 Ncm 时，在手术后一周内将临时修复体连接到种植体上。所有种植体在手术后 2 个月进行最终修复。13 个种植体即刻负重，10 个种植体常规负重。在本对比研究中，在植入后的第三年拍摄放射照片，然后每年拍摄一次，以监测边缘骨丢失情况。
在植入后 8 年，垂直骨丢失的平均变化为 0.009 毫米（P<0.001），而植入后 8 年水平骨丢失的平均变化为 0.026 毫米（P<0.001）。平均边缘骨丢失<0.2 毫米。
在这项回顾性研究中，激光处理种植体显示出种植体周围吸收骨的低比率。
