Finite element analysis has proved to be a very valuable aid in
the field of orthodontics and craniofacial orthopaedics so far as it
has helped determine the precise forces that need to be applied
in order to get physiological tooth movement. One of the major
advantages of this method is that it is completely non-invasive
yet very accurate. It has shown to be very detailed in terms of
results yet sound knowledge of the software giving these results
is required which can be a deterrent when proper digital aids
are not available. Another shortcoming is the unavailability of
accurate mathematical properties for each tooth and bone in
various areas, which though not affecting the results too much
could make the result better if present. Like any method this
also needs improvement to make it more helpful in the field of
orthodontics, among others.
