The following CT exam of the patient with the
radiopaque denture in place (saving the data
obtained to CD-ROM in DICOM format) allowed us
to further plan the details of the treatment [24],
which consisted of inserting six implants in the
maxillary arch at positions 15, 13, 11, 21, 23 and 25. The
distalmost implants were inclined distally to avoid
the maxillary sinus and to create slightly distalized
prosthetic abutments on which to construct a bio-

Case Studies
Fig. 14 SimPlant screenshot giving an idea of the on-screen
planning process. It shows, at a glance, the axial sections
and (top right) the transaxial sections for image number
nine, representing progressive vertical sections of the
panoramic curve that was determined at the outset that
the planning stage, the panoramic section that represents
the plane intersecting the panoramic curve (continuous yellow
line) and a three-dimensional model with the virtual
treatment planning completed.
Figs. 15 to 24 represent various aspects and details of computer-assisted treatment planning for the maxilla: with Figures 15 to 18
showing the three-dimensional model of the maxilla by itself, the maxilla complete with the planned implants, a cranial view
that demonstrates numerous details of the maxillary anatomy and a frontal-occlusal view with the representation of the
radiopaque denture: Note the exact correspondence between the drill holes in the scanning denture and the extensions of the
implants. Figure 19 shows the vertical planes calculated by SimPlant for this three-dimensional model. Figures 20 to 24 show
various software options for creating sections at every level, with a three-dimensional visualization of the orientations of the
planned implants and a characteristic depiction of the individual implants in this particular pyramid-shaped configuration.

mechanically stable fixed complete denture (Fig. 14).
The SimPlant interactive dental implant treatment
planning tool let us work three-dimensionally to
select implants of the appropriate diameters and
lengths as a function of the available vertical and
transversal bone supply. In addition, the tool helped
us optimize the directions, angulations and emergence
profiles to accommodate the prosthetic
aspects of the case [25] (Figs. 15 to 24).
