CASE — Ectodermal dysplasia, 14-year-old (still growing). The most appropriate DEFINITIVE prosthodontic treatment now is:

Correct answer: C. A removable denture (complete/partial overdenture)

• A. Implants are deferred until skeletal growth is essentially complete (late teens); placing them in a growing jaw risks infraposition.
• B. Fixed bridges in a growing patient can impair jaw growth (especially if crossing the midline).
• C. Correct. A removable denture/overdenture is the standard during growth; any conical teeth present are usually kept as overdenture abutments and the prosthesis is remade as the child grows.
• D. Orthodontics alone does not replace the congenitally missing teeth.

Note: Definitive implant therapy is appropriate later, once growth is nearly complete.
