Item Modulo VI manejo de estructuras elaboradas en sistemas cad-cam(Universidad Santiago de Cali, 2022) Bravo Erazo, Veronica; Melendez Narvaez, Iveth Brigett; Torres Morales, Nathali StephanieTechnology together with ceramic materials has made great advances in Dentistry, the clinical use of zirconia thanks to its properties such as resistance to Bending, fatigue and its high toughness widely allows its application in Dental restorations. Zirconium is a polycrystalline ceramic, which has among its Features: low corrosion potential, low thermal conductivity and good Biocompatibility among others. However, due to its high opacity and in this tireless search for materials Aesthetics, the use of laminates on the zirconium core has been required, to give A more natural appearance. Zirconium is not without problems, among them We can mention: spontaneous degradation (which is related to the Hydrothermal transformation) and the stress derived from the manufacturing process. Your low Thermal conductivity means that generally there is no type of sensitivity to Thermal changes (unlike metals) The concerns that it raises among prosthetists are the dreaded "chipping" and that It is not fluorescent, which places it in a different position than the natural tooth. Both Difficulties can be overcome with a good preparation process. The existing materials at our disposal for the manufacture of prostheses are Designed to obtain high success rates with the greatest comfort, thanks to which, With the right knowledge, turn ceramics into a structure that can be Look like a real tooth is no longer an impossible task.
