Prosthetic Habilitation of a Young Patient with Hypohidrotic Ectodermal Dysplasia and Oligodontia: A Case Report of 20 Years of Treatment

Purpose: The aim of this article is to describe the oral habilitation, over a period of 20 years, of a young patient with hypohidrotic ectodermal dysplasia and agenesis of 15 permanent teeth. Materials and Methods: Different clinical interventions were adapted to suit the patient's dental and psychologic stage of development. The prosthodontic treatment, which took place at different ages, comprised several treatment modalities: composite-retained onlay fixed partial dentures, a removable partial denture, toothsupported and implant-supported fixed partial dentures, and laminate crown therapy. Results: The different phases of treatment were successful, and the patient is satisfied from a functional as well as a psychosocial point of view. Conclusion: Extensive prosthodontic treatment in growing individuals should preferably be performed with a multidisciplinary team approach. In treatment that is planned and performed over long periods, this approach has the advantages of continuity and shared responsibility for therapy decisions.
