A clinical review of second molar extraction cases treated over a period of more than 20 years, finding this to be an effective treatment modality in carefully selected cases when combined with adequate orthodontic supervision.

Research has shown that third molars can cause crowding and, in addition to alleviating that problem, second molar replacement allows healthy, fully- developed third molars to erupt in place of the second molars. Consider also the following distinct advantages of second molar replacement.
Ninety percent of people who will
need orthodontic treatment have crowded or protruding teeth.
Nine out of ten. You or your child may be in this ninety percent and
ready to make an important decision about orthodontic treatment.
Modern Method only requires removal of second molars.
For many years the traditional
method of treating crowded and protruding teeth has included removal of
premolar, or bicuspid teeth. The
second molar extraction
is a new and more acceptable approach, with several advantages, for treating
crowded and protruding teeth. This type of extraction will be
beneficial to this patient orthodontic treatment.
