The Effectiveness and Predictability of BioHPP (Biocompatible High-Performance Polymer) Superstructures in Toronto-Branemark Implant-Prosthetic Rehabilitations: A Case Report

Objectives: To evaluate the clinical performance of BioHPP® (Biocompatible High-Performance Polymer) superstructures in full-arch implant-prosthetic rehabilitations following the Toronto-Branemark protocol, focusing on biomechanical and biological outcomes. Methods: A 70-year-old edentulous male patient underwent full-arch implant-prosthetic rehabilitation using BioHPP® superstructures fabricated through a CAD-CAM workflow. Radiological and clinical evaluations were conducted to plan implant placement and assess outcomes after one-year of follow-up. The primary endpoints included prosthetic stability, peri-implant bone resorption, and patient-reported satisfaction. Results: The BioHPP® superstructure demonstrated effective stress distribution, leading to minimal peri-implant bone resorption and improved implant stability. Clinical evaluations showed excellent prosthetic fit and functionality, with no complications during the observation period. Radiological analyses confirmed the absence of prosthetic misfits, while patient-reported outcomes indicated high levels of comfort and aesthetic satisfaction. Conclusions: BioHPP® superstructures offer a promising alternative to traditional materials for full-arch implant-prosthetic rehabilitations, providing significant biomechanical and aesthetic advantages. These findings suggest that BioHPP® may enhance clinical outcomes, though further research with larger cohorts and longer follow-up periods is required to validate its long-term reliability.
