DIGITAL CROWNS AND BRIDGES PROCEDURES
European managers specially Germans, have begun to manufacture taylorized crowns and dental bridges in massive form -from 1983- using machines and digital technology, with such success that they expect replaces in few years many processes made by hand. Experts say that this procedure is of better quality, but quick (6 hours) and but cheap that others made by hand. The current procedure of leaving a dental bite in silicone molds, is expensive, time consuming and painful. Previous to the production of crowns with machines, it is carried out the conventional impression in silicone by means of a bite, passing the mould to a special camera where it is scanned by laser rays. The PC calculates the form of the mould, being obtained in a minute a recreation of the dental defects and the best possible crown. Fed with powder of the wanted material, it builds the skeleton of the crown in 1 hour, the one that is stabilized by means of heating to 1350 degrees Celsius. Finally, the crown is covered with a layer of special ceramic and carried out the dental adaptation to the user.
In the future it is expected to manufacture crowns and bridges from gold, silver, chromium-cobalt alloys, zirconio and others, difficult to break, using powders of these metals and the laser sintering process (heating of the material to several hundred of degrees Celsius), being obtained bridges of gold in 11/2 hour. Although even in experimental stage, a series of intrabucal scanners hopes to replace the unloved dental impression in silicone. Reflected and projected lasers light applied around the teeth, associated to a software of 3D images of the defect and the wanted crown, hope to convert this process in painless and one of great precision.
PUENTES Y CORONAS DENTALES DIGITALES
Empresarios europeos, especialmente alemanes, han empezado a fabricar coronas y puentes dentales personalizados en forma masiva -desde 1983- empleando maquinas y tecnología digital, con tanto éxito que se espera reemplacen dentro de pocos años los procesos hechos a mano. Expertos opinan que este procedimiento es de mejor calidad, más rápido (6 horas) y mas barato que similes hechos a mano. El procedimiento actual de dejar una impresión dental en moldes de silicona, es caro, consume tiempo y es doloroso. Previo a la fabricación de coronas con máquinas, se realiza la convencional impresión en silicona mediante mordida, pasando el molde a una cámara especial donde es scaneada mediante rayos laser. La PC calcula la forma del molde, obteniéndose al minuto recreaciones de los defectos dentales y la mejor corona posible. Alimentada con polvo del material deseado, la máquina construye el esqueleto de la corona en 1 hora, la que se estabiliza mediante calentamiento a 1350 grados Celsius. Finalmente, se cubre la corona con una capa de cerámica especial, se realiza la adaptación dental al usuario y listo.
En el futuro las maquinas fabricaran coronas y puentes de oro, plata, aleaciones de cromo-cobalto, zirconio y otros, dificiles de romperse, empleando polvos de estos metales y el laser sintering process (calentamiento del material a varios cientos de grados Celsius), obteniéndose puentes de oro en 11/2 hora. Aunque aún en etapa experimental, una serie de scanners intraorales esperan reemplazar la odiosa impresion dental en silicona. Luz reflejada y proyectada de lasers aplicados alrededor de los dientes, asociada a un software generador de imágenes en 3D del defecto y la corona deseada, esperan convertir este proceso en indoloro y de gran precision

great read. I would love to follow you on twitter. By the way, did you learn that some chinese hacker had busted twitter yesterday again.
