A Temporary Fixed Prosthetic Solution for Ectodermal Dysplasia Patients 

 with Partial Anodontia: A Case Report

Background:

Ectodermal Dysplasia is a rare and challenging hereditary disorder with abnormal development of tissues and structures of ectodermal origin. (1)

A healthy 8-year-old male patient with Ectodermal Dysplasia was referred to the graduate Prosthodontics clinic at the University of Florida, Gainesville. As shown in the Orthopantomogram (fig.1), The patient has mixeddentition with partial anodontia. Previously, 2 sets of “Pedi Partials” were fabricated in the Pediatrics department to restore: function, esthetics, and phonetics. The mandibular denture became loose twice in a span of 2 months. It reported a fractured soldered joint next to the bands of deciduous #T and #K (Universal Numbering System ).

Objectives:

Most cases reported in the literature propose removable prostheses as an interim solution for patients with ED until their skeletal growth is completed. The use of a temporary material such as Polymethyl Methacrylate (PMMA) that can be frequently relined and does not hinder skeletal growth is an option to be explored. Therefore,  A fixed 10-unit provisional FDP indirectly fabricated using PMMA was the prosthesis of choice in this case.
