Double crown removable partial denture for a patient with ectodermal dysplasia: A clinical report after 31 years

Abstract

This clinical report describes the prosthodontic management of a 5-year-old boy with ectodermal dysplasia who had been followed for 31 years. During the first 15 years, several interim removable overdentures were fabricated and modified according to his skeletal growth. At age 20, after the completion of jaw development, 4 endosseous dental implants were inserted in the mandible with a nerve repositioning procedure. After a 6-month healing period, maxillary and mandibular double crown removable partial dentures (RPDs) using a gold electroforming system were delivered. In the 16 years since delivery, the implants and abutment teeth have shown no pathologic signs. The double crown RPDs supported by implants and natural teeth were found to be an effective, long-term stable treatment option for this patient with hypodontia. The authors are unaware of a longer follow-up period of dental rehabilitation in a patient with ectodermal dysplasia providing satisfactory functional and esthetic results.
