Occasionally, osseointegrated dental implants must be removed because of complications such as malpositioning or screw fracture. This is most often accomplished with a surgical handpiece and trephine. However, a flap is often required to access and visualize the implants. This paper presents a treatment in which computer planning and a 3-dimensional-printed, custom fabricated, surgical guide was used to assist in implant removal. This technique simplified the procedure, allowed conservative removal of peri-implant bone, and permitted subsequent immediate implant replacement.
有时，由于位置不当或螺丝断裂等并发症，必须将牙种植体取出。这通常是通过手术手机和环钻完成的。然而，通常需要进行瓣状手术以接触和观察种植体。本文介绍了一种治疗方法，该方法使用计算机规划和 3 维打印的定制手术导板来辅助植入物取出。该技术简化了手术过程，允许对种植体周围骨进行保守性去除，并允许随后立即进行植入物替换。
