The surgical guide is a static computer-assisted device used for implant surgery planning and guidance. By taking an impression and referring to the patients' three-dimensional computed tomography scan of the desired implant site, a surgical guide can be created. During surgery, the surgical guide aids in achieving the designed implant placement position and direction. We examined and evaluated the long-term clinical outcomes of implant surgery using surgical guides.
This study investigated a total of 15 patients with 32 implants that were placed using surgical guides from 2009 to 2011 with a mean follow-up period extended beyond 10 years. Patient demographics and implant survival rates were recorded. We analyzed marginal bone loss (MBL) by assessing the radiographs acquired at installation, three months after installation, and one month, one, two, and five years after prosthesis delivery.
The mean patient age was 57.33 years at implant placement. Of the 32 implants, five implants were placed in the anterior region and 27 implants were in the posterior region. Six implants failed and three of them were replaced, resulting in an 81.25% survival rate. The mean follow-up period was 10 years and nine months. Mean MBL compared to post-installation was significantly higher than at three months after installation, and one month, one, two, and five years after prosthesis delivery. Mean MBL at three months after installation, and one month, one year, and two years were significantly higher compared to the previous visit (<0.05). However, MBL at five years after prosthesis delivery did not differ significantly compared to at two years.
In this study, implant rehabilitation assisted by surgical guides exhibited favorable survival rates. With the limitation of the sample amount in this study, further research and more samples are required to evaluate the long-term clinical effectiveness of surgical guides.
手术导板是一种用于种植手术规划和引导的静态计算机辅助设备。通过制取印模并参考患者所需种植部位的三维计算机断层扫描，可制作手术导板。在手术过程中，手术导板有助于实现设计好的种植体植入位置和方向。我们检查并评估了使用手术导板进行种植手术的长期临床效果。
本研究共调查了15例患者，这些患者在2009年至2011年间使用手术导板植入了32颗种植体，平均随访期超过10年。记录了患者的人口统计学数据和种植体存活率。我们通过评估种植体植入时、植入后三个月以及义齿交付后1个月、1年、2年和5年获取的X光片来分析边缘骨吸收（MBL）情况。
种植体植入时患者的平均年龄为57.33岁。32颗种植体中，5颗位于前部区域，27颗位于后部区域。6颗种植体失败，其中3颗进行了更换，存活率为81.25%。平均随访期为10年9个月。与植入后相比，平均MBL在植入后三个月以及义齿交付后1个月、1年、2年和5年时显著更高。与上一次就诊相比，植入后三个月以及义齿交付后1个月、1年和2年时的平均MBL显著更高（<0.05）。然而，义齿交付后5年时的MBL与2年时相比无显著差异。
在本研究中，手术导板辅助的种植修复显示出良好的存活率。鉴于本研究样本量的局限性，需要进一步研究和更多样本以评估手术导板的长期临床效果。
