Oral rehabilitation with endosseous implants in a child with ectodermal dysplasia: a case report

Authors:

ABSTRACT

Aim

The purpose of this article is to report the clinical course of a 12-year-old child with ectodermal dysplasia who
was treated with an implant-supported overdenture for the mandible and an overdenture for the maxilla.

Case report

Two dental implants were placed in the canine regions of the mandible. The maxillary teeth were prepared for the milled copings.
Because the preparation of parallel walls was difficult, near-parallelism with an angle of convergence or taper of
approximately 5 degrees was achieved. The cervical third of the teeth was prepared to be as parallel as possible to one
another. In addition, the occlusal surfaces were reduced 1.5 mm, and the axial surfaces were reduced 1 mm. Occlusal
reduction was performed to provide adequate thickness for the overlying denture base material. A chamfer finish line was
prepared. The copings were cast with a Cr-Ni-based metal alloy and luted, bilateral balanced occlusion was developed using
anatomic acrylic teeth. An impression was taken with an individual tray for impressions of overdentures. In response to the
patient's dry mucosa, the impressions were taken using rapid-setting silicone impression material with high elasticity.
Bilateral balanced occlusion was achieved using anatomic acrylic teeth for overdentures. The maxillary overdenture and
implant-supported mandibular overdenture were prepared by conventional methods using thermal-curing acrylic resin. The
patient was seen 48 hours later for adjustment, then after 1 and 2 weeks, 1, 3, and 6 months, and 1 year and he is still
satisfied with his prosthesis both aesthetically and functionally.

Conclusion

The use of endosseous implants in the prosthetic rehabilitation of children with ectodermal dysplasia may provide a considerable improvement in comparison with traditional prosthetic methods.
