Implant-supported fixed prosthesis in a hypohidrotic ectodermal dysplasia patient: A case report with 3 years follow-up and review of the literature

INTRODUCTION:: Ectodermal dysplasia (ED) is a rare inherited disorder that affects structures derived from embryonic ectoderm. Due to associated ridge deficiency, and anodontia found in these patients, multiple surgeries are often indicated before replacement of missing teeth with implants, resulting in increased morbidity and treatment time. MATERIALS AND METHODS:: In this case report, a 31-year-old woman was transitioned from failing tooth-supported fixed restorations to a fully implant-supported fixed prosthesis using immediate implants and narrow diameter implants (NDI). By using some of her existing dentition to support the provisional restorations while osseointegration took place, the patient was able to retain function during treatment. Full-fixed implant-supported prostheses were delivered, providing an esthetic and functional outcome that has been maintained for 3 years. CONCLUSION:: In ED patients, NDI together with immediate implant placement can be used successfully to support a complete fixed restoration and should be considered as an alternative to major reconstruction surgeries. Key factors associated with increased predictability are discussed together with a review of the literature.
