Prosthodontic management of abnormal tooth development secondary to chemoradiotherapy: a clinical report

Late effects of chemoradiotherapy for childhood cancer treatment include developmental disturbances of the maxillofacial and dentoalveolar structures. Prosthodontic rehabilitation of these patients presents a significant challenge in restoring function, esthetics, and comfort. This clinical report describes the prosthodontic management of a young patient who received chemoradiotherapy for neuroblastoma and subsequently developed tooth abnormalities. Osseointegrated implants and an implant-connecting bar along with an attachment system were used to provide retention, support, and stability of a removable mandibular overdenture opposing a conventional maxillary complete denture.
