09 Jul Complutense University of Madrid publishes a clinical report about improving PMMA resin using graphene for a definitive prosthodontic rehabilitation
The report drafted by the Department of Conservative Dentistry and Orofacial Prosthodontics School of Dentistry (Complutense University of Madrid) supports the incorporation of graphene oxide (GO) into polymethyl methacrylate (PMMA) resin for a definitive maxillary rehabilitation, combined with an intraoral digital impression and a three-dimensional facial scan.
In the authors’ view, the incorporation of carbon nanotubes, such as GO, in acrylic resins may enhance the resin’s mechanical properties and decrease the degree of contraction during polymerization.
According to the study, after 8 months of the placement of the definitive prosthesis, no mechanical, aesthetic, or biologic complications were reported, and the soft tissues showed excellent health and stability. Furthermore, el PMMA exhibited better antimicrobial-adhesion effects after incorporating GO than those exhibited by pure PMMA via increased hydrophilicity.
In conclusion, and taking into account the reduced follow-up time of this clinical report, the incorporation of GO in PMMA resins seems to be a suitable option, because provide a definitive, reliable material for prosthetic rehabilitation. However, further studies are needed to ensure rigorous scientific support of these techniques and new materials.
