Interim prostheses are required for the management of complex prosthodontic treatment which sometimes comprises both fixed and removable prostheses in the same arch. The traditional workflow for interim combined fixed and removable prostheses is time consuming and results can be unpredictable. A novel integrated digital workflow was adopted in the management of long-term interim combined fixed and removable prostheses. Highly cross-linked polymethyl methacrylate was used for the digital fabrication of both interim fixed and removable prostheses. The patient was satisfied with the esthetic and clinical outcomes after 6 months without any complications.

A 55-year-old man was referred for consultation and treatment regarding missing teeth, fractured crowns, and defective restorations. His previous treatment had included a mandibular RPD, but he did not wear it because of discomfort and limited function. The patient was interested in saving his remaining teeth and receiving a new mandibular RPD. Clinical examination revealed partially edentulous arches with poorly fitting crowns, secondary caries, and retained roots (Fig. 1A). Open margins of

This clinical report details the combined design and fabrication of interim fixed restorations and an interim RPD in the same arch by using CAD-CAM technology and highly cross-linked PMMA. The patient was satisfied with the esthetic and functional outcomes. The number of appointments was significantly reduced. If severe complications such as fracture occur, replacement should be easy to manage. The dental laboratory technician can simply remake the failed interim prosthesis from the existing

A novel integrated digital workflow is presented for the management of long-term interim combined fixed and removable prostheses. This integrated digital workflow allows the simultaneous design and fabrication of both fixed and removable interim prostheses and thus more predictable esthetic and functional outcomes.
