Prosthodontic management of patients with such dysplastic
condition necessitates a multidisciplinary approach. However
the definitive treatment can only be rendered after the
completion of growth period, and till then a provisional
treatment can be given to enhance the aesthetic and functional
requirement of the patient. This case report describes the

       Ectodermal dysplasia (ED) is a hereditary disorder that
can affect several ectodermal structures. These structures may
include: skin, hair, nails, teeth, nerve cells, sweat glands, parts
of the eye and ear, and parts of other organs.
