  • Three‐dimensional guidance system for implant placement

    A computed tomography (CT) scan is performed to provide image data for a three‐dimensional guidance construct for implant placement. A guide is a structure or marking that directs the motion or positioning of something, thus in implant dentistry this term should not be used as a synonym for surgical implant guide.

  • Threaded implant

    An endosseous, rootform dental implant, with threads similar to a screw. It is also known as a screw‐shaped implant. It may be parallel‐sided or tapered.  

  • Thread run out

    The end section of a threaded shank that is not cut or rolled to full depth providing the transition between the fastener shank and full‐depth threads.  

  • Thread root

    The bottom of the groove between the two flanking surfaces of the thread, whether internal or external.  

  • Thread pitch

    The distance from a point on the screw thread to a corresponding point on the next thread measured parallel to the axis.  

  • Thread path

    The conduit in the internal aspect of a screw access hole which guides the threads of a component. Also, the pathway created by a bone tap in an osteotomy, which directs a dental implant during insertion.  

  • Thread lead

    The distance a screw thread advances axially in one turn.  

  • Thread flank

    The portion of a screw thread that joins the thread root to the screw crest.  

  • Thread depth

    The distance between the major and minor diameter of the thread.  

  • Thread crest

    The prominent part of a thread, whether internal or external.
