BACKGROUND – The Invisalign system for orthodontic treatment
of adults was introduced in 1999 and since has been widely used
internationally as well as in Denmark. However, the indications
for the use of the system seem unclear. In the present article two
patient cases with irregular anterior teeth were straightened.
CASE STUDIES – Two young adults with spacing or crowding
positions of the teeth in the front region, respectively, and
with normal molar occlusions were treated with the Invisalign
system. 10 set of aligners were used for the first patients,
whereas 23 sets were used for the patient with crowding. For
the following refinement, four set of aligners were used in
both cases. The posttreatment consisted of using aligners for
the night and bonded wired retentions. In both cases correct
positions of the anterior teeth were achieved.
CONCLUSION – Irregular teeth with limited spacing or crowding
positions in the front and normal occlusion can be moved to
correct positions by use of the Invisalign system.
