A Technique to Improve an Ailing Interim Implant-Supported Fixed Partial Denture

Objective: Implant-supported interim prostheses aims to preserve the natural periodontal architecture, protect the surrounding tissues, and provide patients with immediate esthetic and functional outcomes. The objective of this clinical technique article is to present a reliable method to replace an ailing interim implant-supported fixed partial denture (FPD). Clinical considerations: Patient presented with an ailing interim implant-supported fixed partial denture (FPD) replacing all lower anterior incisors. After case was clinically and radiographically evaluated, diagnostic casts were mounted. Once the interim FPD was retrieved, provisional abutments were dislodged and cleaned. Implant impression copings were carried out intraorally using pattern resin; its respective implant replicas were attached and screwed. Healing abutments were hand-screwed to keep the periimplant tissue architecture until the delivering of the newly fabricated interim FPD. The implant impression copings and its respective implant replicas were positioned on the diagnostic cast using dental stone. The two provisional abutments were positioned on the implant replicas and screwed in place for the relining of the new interim prosthesis previously made with acrylic resin. The new interim FPD was finished, polished and delivered. Conclusion: This clinical technique presents a reliable method for fabricating an immediate interim implant-supported FPD to replace an existing ailing interim prosthesis.
