La impresión 3D es una herramienta innovadora que ha experimentado un crecimiento significativo en diversas disciplinas, tanto industriales como médicas. En particular, el campo odontológico ha aprovechado las características únicas que esta tecnología ofrece, entre las cuales destacan: (i) La personalización de diferentes dispositivos o modelos dentales; mediante el uso de imágenes médicas obtenidas de tomografías, resonancias y escaneos intraorales y extraorales, es posible diseñar y fabricar modelos dentales adaptados a las necesidades específicas de cada paciente. (ii) La precisión en la fabricación de los dispositivos dentales; las diferentes técnicas de manufacturación aditiva, como la estereolitografía (SLA), el modelado por deposición fundida (FDM), la sinterización por láser (SLS), el procesado digital de luz (DLP) y la pantalla de cristal líquido (LCD), ofrecen una alta resolución que garantiza la precisión en la fabricación de dispositivos dentales. (iii) Mejora en la eficiencia clínica; debido a la disminución en los tiempos de fabricación, al estandarizar y controlar el flujo de trabajo digital en comparación con los métodos tradicionales. (iv) Los avances en materiales para la impresión 3D, en particular el uso de resinas biocompatibles en las técnicas de fotopolimerización (SLA, DLP y LCD), que son ampliamente empleadas en el campo dental. Además, se utilizan otros materiales con menor frecuencia, como polímeros termoplásticos, aleaciones metálicas, cerámicas e hidrogeles. (v) Variedad de aplicaciones según la especialidad odontológica. Por consiguiente, se exploran las contribuciones de la impresión 3D en cada especialidad odontológica con el propósito de analizar los avances tecnológicos y su impacto en la atención de los pacientes.

Prosthetic joint infection represents a problem that worsens the patient’s quality of life and produces an economic impact on health systems. We report the anodization of Ti6Al4V coupons obtained by electron beam melting to produce a nanostructured surface. Anodization at 10 V produced TiO2 nanopores with a diameter in the range of 15–20 nm. Thereafter, Ag nanoparticles (AgNPs) were deposited in three different ways to provide antibacterial functionality to the coatings: electrochemically, thermally, and chemically. The electrochemical method did not provide good coverage of AgNPs. At 0.1 V of synthesis potential, cubic, octahedral, and truncated octahedral Ag crystals were obtained. The thermal method provided a good distribution of AgNPs but it damaged the TiO2 nanostructure. The chemical method showed the best distribution of AgNPs over the anodized surface and preserved the anodized nanostructure. For this reason, the chemical method was selected to perform further studies. Ag+ release was monitored in simulated body fluid at 37 °C, reaching 1.86 mg Ag+/L after 42 days. The antibacterial coating showed excellent antibacterial activity and inhibited biofilm formation for Staphylococcus epidermidis RP62A and Staphylococcus aureus V329 strains (lethality > 99.9% for both bacteria and assays).
