Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described in this case enable practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissues coronal to the implant-abutment interface. This approach involves atraumatic tooth removal without flap elevation, and placing a bone graft into the residual gap around an immediate fresh-socket anterior implant with a screw-retained provisional restoration acting as a prosthetic socket seal device.
种植体设计的改进有助于将即刻前牙种植成功推进到新鲜拔牙窝中。本病例中描述的临床技术使从业者能够通过一种方法实现可预测的美学成功,该方法可限制拔牙部位牙槽嵴颊侧轮廓变化的量,并有可能增加种植体-基台界面冠方种植体周围软组织的厚度。这种方法包括在不掀起瓣的情况下进行无创拔牙,并将骨移植到即刻新鲜拔牙窝前牙种植体周围的剩余间隙中,使用螺丝固位的临时修复体作为修复性牙槽窝封闭装置。
