Este informe clínico describe la incorporación de óxido de grafeno (GO) en resinas de polimetilmetacrilato (PMMA) para mejorar sus propiedades mecánicas, un factor limitante en rehabilitaciones protésicas definitivas. Se evaluó su aplicación en una rehabilitación maxilar, combinando tecnología de impresión digital intraoral y escaneo facial tridimensional. Tras un seguimiento de ocho meses, la prótesis mostró ausencia de complicaciones mecánicas, estéticas o biológicas, con tejidos blandos estables y saludables. Los resultados preliminares sugieren que el GO es una opción prometedora para mejorar las resinas PMMA en prostodoncia. No obstante, se subraya la necesidad de estudios adicionales para validar científicamente su uso y el de estas técnicas combinadas.
The use of acrylic resins as a definitive material has shown some advantages comparing to other definitive materials. However, their poor mechanical properties remain a major drawback. In this case report, graphene oxide (GO) was incorporated into polymethyl methacrylate (PMMA) resin for a definitive maxillary rehabilitation, combined with an intraoral digital impression and a three-dimensional facial scan. 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. The incorporation of GO in PMMA resins seems to be a suitable option for prosthetic rehabilitation. However, further studies are needed to ensure rigorous scientific support of these techniques and materials. Key words: Computer-aided design, computer-aided manufacturing, dental impression technique, dental prosthesis; graphene oxide.
