摘要： The invention relates to a process of producing a dental zirconia article, the process comprising the step of sintering a porous dental zirconia article, the sintering comprising a heat-treatment segment A characterized by a heating rate of at least 3 K/sec up to a temperature of at least 1,200° C., the porous dental zirconia article being composed of a zirconia material containing 6.0 to 8.0 wt. % yttria, 0.05 to 0.12 wt. % alumina and comprising a coloring component containing Tb, the porous dental zirconia article being essentially free of Fe components. The invention also relates to a process comprising the additional step of applying a glazing composition to the outer surface of the porous zirconia article before the heat-treatment or sintering is conducted.

摘要： A gutta-percha-silver composite with determined weight percentage and particle size, is provided. The composite exhibits electro-conductivity greater than the standard gutta-percha composites. The new material simplifies root canal treatments, shortens the times both for clinician and patients, and reduces the exposure to patients from X-rays. The material is not only electro-conductive; it is anti-bacterial, which improves the outcomes of the procedures. Also, it has improved thermal conductivity, and mechanical properties.
