Oral Rehabilitation with Endosseous Implants in a Child with Ectodermal Dysplasia: A Case Report

Abstract

Aim The purpose of this article is to report the clinicalcourse of a 12-year-old child with ectodermal dysplasia whowas treated with an implant-supported overdenture for themandible and an overdenture for the maxilla.Case report Two dental implants were placed in the canineregions of the mandible. The maxillary teeth were preparedfor the milled copings. Because the preparation of parallelwalls was difficult, near-parallelism with an angle ofconvergence or taper of approximately 5 degrees wasachieved. The cervical third of the teeth was prepared to beas parallel as possible to one another. In addition, theocclusal surfaces were reduced 1.5 mm, and the axialsurfaces were reduced 1 mm. Occlusal reduction wasperformed to provide adequate thickness for the overlyingdenture base material. A chamfer finish line was prepared.The copings were cast with a Cr-Ni-based metal alloy andluted, bilateral balanced occlusion was developed usinganatomic acrylic teeth. An impression was taken with anindividual tray for impressions of overdentures. In responseto the patient's dry mucosa, the impressions were takenusing rapid-setting silicone impression material with highelasticity. Bilateral balanced occlusion was achieved usinganatomic acrylic teeth for overdentures. The maxillaryoverdenture and implant-supported mandibularoverdenture were prepared by conventional methods usingthermal-curing acrylic resin. The patient was seen 48 hourslater for adjustment, then after 1 and 2 weeks, 1, 3, and 6months, and 1 year and he is still satisfied with hisprosthesis both aesthetically and functionally.Conclusion The use of endosseous implants in theprosthetic rehabilitation of children with ectodermaldysplasia may provide a considerable improvement incomparison with traditional prosthetic methods.
