- Abstract
The objective of this study is to present the advantages of using non-metallic polymeric frameworks obtained through subtractive technologies using polyetheretherketone in fixed proshodontics. Matherial and method: for the oral rehabilitation of a completely bimaxillary edentulous patient through implant-supported fixed prostheses, maxillary and mandibular all on six, a technological alternative was approached. It involved creating a non-metallic framework obtained through subtraction from a polyetheretherketone disc-bre CAM.BioHPP, 16mm, Bredent. After the surgical phase, the stage of creating the fixed prosthesis followed, following the characteristic protocol of the digital workflow, but it was also associated with specific stages of traditional technologies. The digital design of the restoration was performed in Exocad, on the virtual model obtained after scanning the analog model using the 3D scanner Medit Identica T300. The finalization of the morphology of the fixed prosthesis was achieved using photopolymerizable acrylic resin, Sr Nexco Paste Ivoclar Vivadent, step by step technique. Results. The manufacturing of fully polymeric fixed prostheses, on non-metallic frameworks milled from BioHpp, represents a viable alternative in complex therapies of implant prosthodontics, and the functionality of the prosthesis is long-lasting. Conclusions. Implant-supported fixed prostheses with the non-metallic framework milled from polyetheretherketone, ensure patient comfort due to their reduced weight, and the characteristic elasticity module of BioHPP allows proper damping of forces in the oral cavity, which is an advantage in implant prosthodontics.
