RESUMEN

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. Osseo-integrated 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.

SUMMARY

Young adults with abnormal dental development secondary to chemoradiotherapy for childhood malignancy present a treatment challenge. Prosthodontic rehabilitation is often difficult to achieve due to the shortened roots with poor long-term prognosis. The use of osseointegrated implants contributes significantly to the prosthodontic rehabilitation, resulting in improved masticatory performance and comfort. This clinical report presented the prosthodontic management of a patient with dental abnormalties secondary to chemoradiotherapy using osseointegrated implants and an implant connecting bar with a ball attachment system to assist with retention, support, and stability of a mandibular overdenture opposing a maxillary complete denture.
