predictability, and to effectively repeat an
original, potentially decades-old outcome
that the patient finds agreeable can be
diffi cult. This task is challenging in both
analog and digital workflows, but from
the cases I have studied and undertaken, it
can be a more predictable experience using
digital denture technology.
Another signifi cant challenge: reproducing
what feels " normal " to the patient.
While some edentulous patients will need
or want to replace a prosthesis they have
been using for as few as fi ve years, many
will visit your offi ce wearing a decades-old
device. In my practice, I have replaced several
prostheses my patients had been wearing for
more than 30 years!
In my experience, many denture wearers
Fig. 8: Step 3: Using the other side of the gauge, place
the friendly rounded edge just under the nose and
under the chin. As you can see here, there is a space
between the chin and the curve; therefore the patient
is currently overclosed. Close the gauge until it touches
the patient's chin to determine the existing situation,
measuring the difference between the patient's current
vertical dimension of occlusion (VDO) and new proposed
VDO.
use their prostheses for longer than they
should in an ideal scenario. They avoid
change because they fear a new denture
might not be as comfortable or aesthetically
pleasing as their current device, to which
they have become accustomed.
Digital potential
Most people reading this article will be
more familiar with the analog approach.
That makes sense: It is the approach we
are all schooled in and trained on and
have been practicing since we entered the
industry. Regardless of whether you are
just starting out in your career or you're a
seasoned professional who feels your current
workfl ow is adequate, you should continually
ask yourself: But is there a better way?
Traditionally, reproducing a hand-crafted

denture is arduous; using the traditional
(analog) processes, it is diffi cult to duplicate
an existing prosthetic exactly or at the very
least, within normal limits. As any dental
professional knows, unfortunately, an analog
denture relies heavily on the hand-eye
coordination and motor dexterity of the
person fabricating it-which means dentures
are exposed to signifi cant potentialities for
human error.
