Conclusion
For dentists, the drive to replace missing teeth
in our patients can be a strong one. It's one that
comes with our education and training. Th e goal
in looking at the SDA concept is not to suggest
not replacing missing teeth-our ability to help
patients regain full form and function after tooth
loss has never had better materials and treatment
options then available today. Rather, the
goal is to help better understand in those cases
when, for whatever reason, replacing missing
teeth isn't reasonable or possible, and just how a
shortened dental arch concept might be of value
and give us additional treatment option.
Th e literature and data have shown that a SDA
of anterior with premolar/molar tooth combinations
can and most often does fulfi ll the requirements
for a satisfactory and functional dentition.
Consideration as to patient needs, health and
desires frequently leads us to determine that no
additional dentistry may be the route of choice.
A planned case of shortened dental arches
can provide for a cost-eff ective treatment with
a functional and stable long-term dentition. Th e
concept can be biologically sound-one in which
we can be confi dent and positive-and deserves
consideration as an option among others in
treatment planning for the partially edentulous
patient. DT
