Surgical Plan Overview

The Navigator™ System For CT Guided Surgery works in conjunction with the surgical plan, which is provided by the CT planning software company. Each surgical plan is case-specific to provide direction regarding the instrumentation that will be used for each implant site.

The surgical plan specifies the depth line for instruments that pass directly through the surgical guide Master Tubes including the Tissue Punch, Starter Drill and Bone Taps. These instruments have landmarks referenced as (1), (2), (3) and (4) that indicate the proper depth to which these instruments should be used through the Master Tubes (figure 1). There are three lines on each instrument; the first line represents depth line (1), while the top of the instrument represents depth line (4). The instruments pass through the Master Tube until the center of the specified line on the instrument reaches the top of the Master Tube (figure 2).

The depth lines also determine what Implant Mount and Implant Analog Mount must be used. Theses are labeled by diameter and length. Therefore a 4mm implant that has a 3 depth line will be specified as a 4(3).
