High translucent dental zirconia powder for dental blocks
Using the latest hydrolysis processes and nano-technologies, Sinocean produces the dental grade zirconia powders.In the field of bioceramic materials, dental implant is one of the most widely applied dental restoration techniques, which can help to restore the normal shape and function of the teeth. It is mainly divided into two parts, namely implant and crown. Due to the good biocompatibility of zirconia ceramics, the morphology, color and luster of the natural teeth can be restored to the maximum degree. It has been widely used in the field of clinical dentistry.
