What is Anterior Maxillary Distraction or AMD?
It is an absolute beauty of a technique wherein new bone is
made to be deposited by the patient’s own body. It’s a type of distraction
Why AMD ?
Research has proven ( we have one of the, if not THE largest
publications on the type of surgery in the entire world) that with this type of
procedure, the patients speech improves and never ever worsens. Also, there is
no relapse. Patient compliance is way better as there is no appliance on the
head or outside, they could go to school or work. The length of hospital stay
is lesser than other distraction procedures. The procedure can be done for
younger individuals as early as 11 years.
If so many advantages, why is not popular?
Cause this is a relatively newer technique.
Needs a team work as the distractor is custom made.
Steeper learning curve surgically as some blind osteotomies
need to be done.
But then… who says it’s not popular??!!
At Richardsons, more than 500 such surgeries have been
performed in the last twelve years alone, again of the largest in the world.
Dr Sunil Richardson has been invited by many countries to
demonstrate this procedure, Spain and Bulgaria to name a couple.
One of his lectures for the grand rounds at Stanford
University, California, USA and Yale University, USA was also in Anterior
So who needs this anyways…
Any patient who has an underbite could benefit from this
All patients with cleft lip and cleft palate with slight or
severe less growth on the upper jaw will also benefit from the same.
