Treatment with clear plastic aligners is a standard of
state-of-the-art orthodontics. In its foreground stands
the Invisalign-System which has some remarkable
advantages as compared to established orthodontic
therapy. These advantages comprise mainly of an individual
planning and visualization of the treatment
goal, an unimpeded function and oral hygiene and
especially almost unmatched aesthetics which result in
an exceptional patient acceptance and satisfaction.
These advantages are contrasted by some disadvantages:
only tipping movements are practically safe to
perform; rotations, extrusions and intrusions of teeth as
well as changes in tooth inclination and of the occlusion,
however, not. Some of these limitations can be
overcome with mechanical adjuncts which though
have to be fabricated in such a way that they satisfy the
same aesthetical demands which are expected from
the Invisalign-System. Still, there are certain malocclusions
or symptoms in which treatment with the
Invisalign-System is contraindicated. The described
aspects will be demonstrated with clinical examples as
well as with results of clinical investigations.
