Application Of Zirconia Ceramics in Dental Implants


In order to improve the aesthetics through the post color, Al-Zirconium machinable posts can be designed for the restoration of single missing teeth in the maxillary anterior region. This beautiful machinable ceramic anterior dental implant foundation is made of alumina, plutonium oxide and zirconia sintered into a certain form of foundation post embryo, which can be machined and then infiltrated with glass frit.

Zirconia ceramic implant abutments not only have good oral material properties but also have excellent biocompatibility. Rimondini et al. compared the colonization of bacteria such as Streptococcus mutans, Streptococcus sanguis, Actinomyces viscosus and Porphyromonas gingivalis on the surfaces of zirconia ceramic piles and pure titanium piles in in vitro experiments, and found that deformation chains on the surface of zirconia ceramic piles The colonization of cocci exceeded that of titanium posts, and Streptococcus sanguis was more likely to colonize the surface of titanium posts. In vivo experiments found that the colonization of periodontal pathogens on the surface of titanium posts exceeded that of zirconia ceramic posts. Zirconia ceramic abutments are more than twice as resistant to fracture as alumina ceramic abutments.
