Ectodermal dysplasia: an 11-year follow-up of siblings with 2 implant treatment approaches.

PURPOSE To describe 2 different treatment approaches for a 20-year-old Caucasian man and his 22-year-old sister who were affected by ectodermal dysplasia (ED) and compromised maxillary bone. MATERIALS AND METHODS The sister had a history of an iliac crest transplant with 6 implants placed in the maxillary and mandibular arches, 6 years before complications. It was necessary to debride the right sinus, remove the failing infected bone graft and 2 implants. Her brother presented with missing teeth, few remaining deciduous teeth, and wearing all-acrylic resin temporary partials in both the maxillary and mandibular arches. RESULTS Zygomatic and pterygomaxillary implants were used to rehabilitate the brother with a screw-retained fixed prostheses. His sister had 6 new maxillary implants. Both siblings' mandibular arches were restored with screw-retained implant-supported prostheses. CONCLUSION Although these siblings affected with ED had different treatment approaches, they both eventually obtained successful outcomes. The brother's treatment was expedited. Both siblings have been followed for a period of 11 years, and all postoperative evaluations have been uneventful.
