Abstract

This clinical report presents a 7-year-old patient with ectodermal dysplasia and a newly identified ectodysplasin A (EDA) gene mutation (c.965 T>C). A removable partial denture combined with a complete denture was provided after considering the relevant factors. Based on digital smile design, resin crowns were fabricated to restore the cone-shaped teeth esthetically. Facial scan parameters and maxillofacial landmark localization on cone beam computed tomography (CBCT) images were combined for the registration of jaw relation, and a Gothic arch was subsequently 3-dimensionally printed for verification. Ultimately, dentures with accurate occlusion and satisfactory retention were delivered for this young patient with inadequate bone volume and poor fit that markedly improved his esthetics and function.
