Removable Partial Denture With Semi-Precision Attachments Combined With a Fixed Partial Denture in a Patient Undergoing Chemotherapy: A Case Report

The combination of a removable partial denture and a fixed partial denture connected by semi-precision attachments is an alternative for partially edentulous patients with systemic limitations to implant surgery. This article reports the oral rehabilitation of a 66-year-old woman undergoing chemotherapy for metastasis who sought replacement of her maxillary and mandibular removable partial dentures. After oral environment preparation, which included periodontal and endodontic treatment, the case was analyzed on a semi-adjustable articulator. The maxillary arch was rehabilitated with a three-unit fixed partial denture incorporating two extracoronal semi-precision attachments connected to a removable partial denture, and the mandibular arch with a removable partial denture with conventional clasps and a milled crown on one abutment. The attachments eliminated visible clasps, splinted abutments with mobility, and favored retention and stability, although they are technique-sensitive and more costly. Combining a removable partial denture and a fixed partial denture with semi-precision attachments was a functional and esthetic alternative for a patient with a systemic contraindication to implants and contributed to her comfort. Long-term follow-up is needed to evaluate prosthesis longevity and periodontal response.
