DENTAL TRIBUNE | March 2010 Clinical: Digital Perspective 11A AD Figs. 1a–c (above and below): CBCT study performed with the iCAT CBCT machine (Imaging Sciences International, Hatfield, Pa.) while the patient wore a radiographic guide (blue shadow). By utilizing ImplantMaster™ software (iDent Imaging, Foster City, Calif.), the prosthetically aligned acrylic teeth in the radiographic guide, plus the resid- ual bone trajectory and the mandibular canal, facilitated the optimal virtual planning of implants’ trajectory, depth, length and diameter. Images are shown in two dimensions: panoramic slice (1a) and cross sections (1b, c). These cross sections correspond to the patient’s lower right and left edentulous region (Nos. 19 and 29). Note the mandibu- lar canal illustrated by the red lines and circles. Figs. 2a–c (at right): By utilizing ImplantMaster software, a 3-D reconstruction of a patient’s anat- omy was achieved and a virtual surgical guidance template (2a, b) was designed and computer manu- factured with precise drilling hole distribution and the trajectory for implants Nos. 19 and 29 (2c). Spe- cial metal sleeves were assembled in the holes that can house a series of tool inserts that accommodate a diversity of implant systems and drilling sequence as required by each implant brand.
