Management of Severe Maxillary Atrophy in a Patient With Hay-Wells Syndrome.

Ankyloblepharon-ectodermal defects-cleft lip/palate syndrome (AEC), also known as Hay-Wells syndrome, is a rare systemic disorder that affects the development of derivatives of ectodermal tissues, which in some cases results in the development of severe maxillary atrophy. This brief clinical report illustrates the use of a patient-specific subperiosteal implant to perform dental rehabilitation in a patient with AEC.
