The three-dimensional orientation of dental implant is transferred to a model by means of transfer device and impression material. If more than one implant is inserted and fixtures are not perfectly parallel, the impression may become distorted when removed from the mouth. In this case, a transfer that can be disengaged from the internal implant-abutment connection and removed together with the tray could be useful. An impression transfer device composed of a proper transfer, an inner hexagon and a central screw is described. When the central screw and the hexagon are removed, the proper transfer is free to move horizontally and the tray can be removed from the mouth without distortion of the impression material.
牙种植体的三维方向通过转移装置和印模材料转移到模型上。如果植入了多个种植体且种植体部件不完全平行，当印模从口腔中取出时可能会变形。在这种情况下，一种可从种植体-基台内部连接分离并与托盘一起取出的转移装置可能会很有用。本文描述了一种由合适的转移体、内六角和中心螺钉组成的印模转移装置。当中心螺钉和六角形部件被移除时，合适的转移体可自由水平移动，托盘可从口腔中取出而不会使印模材料变形。
