educing treatment time with digital dentistry
❯ Third Appointment
The lab processed the denture to the
titanium bar with acrylic to finish the
final prosthesis (Fig. 32). The provisional
was removed and the final fixed
implant denture was delivered. The
patient was extremely happy with the
fit, comfort and function of the final
prosthesis (Fig. 33).
Discussion
Achieving adequate primary stability is
a must before proceeding with an implant-retained
provisional or final prosthesis.
Had sufficient primary stability
not been achieved for all of the implants
upon surgical placement, the patient’s
existing denture could have been
used as a provisional after relieving it
to accommodate healing abutments or
cover screws and sutures. Patient comfort
was the primary consideration in
the decision to construct a new provisional
denture instead of modifying the
existing denture, which lacked retention
and would have posed problems if
placed on a new surgical site.
Conclusion
Guided surgery and dental CAD/CAM
are complementary technologies that
can make the surgical and restorative
phases of implant therapy more
efficient and predictable. Guided surgery
offers extremely accurate implant
placement relative to the treatment
plan. Because we can predict the implant
position postsurgically, prosthesis
design can be done pre-surgically.
Advanced treatment protocols that
leverage digital impressions, treatment
planning, guided surgery and dental
CAD/CAM technology are transforming
implant therapy, shortening treatment
times and improving prosthetic
outcomes (Fig. 34). As the technologies
behind implant digital dentistry continue
to evolve and converge, we can
expect further reductions in the time
required to restore implant cases and
increasingly consistent results. IM
Achieving adequate
primary stability
is a must before
proceeding with an
implant-retained
provisional or
final prosthesis.
