Further experimentation with different dopants and associated sintering protocols to produce more translucent phases would appear to be a profitable line of research, with ...

Although the use of zirconia ceramics for dental applications is ongoing, the best method to achieve a durable bond between the ceramic and the tooth structure is still unknown. The only consensus found in the literature is that hydrofluoric acid etching and common silane agents are not effective with zirconia ceramics[ 81 - 83 ].

zirconia was proposed as a new ceramic material in the later part of 20th century. It has become a popular alternative to. alumina as biomaterial and is being used in dental applications for ...

Zirconium (Zr) is a solid metal with similar physicochemical properties to titanium. Thus zirconia also can be used in dental implants as abutments attached to the implants, and it provides some advantages over alumina in order to solve the problem of brittleness and the potential failure of implants.

Zirconia: Taking Dental Restorations to the Next Level. JanJolly. October 8, 2019. Since the introduction of porcelain-fused-to-metal (PFM) crowns in the 1960s, the dental industry has sought materials with both the esthetic value of porcelain, and the strength of noble metals to withstand the pressure of posterior occlusal forces.

Zirconia dental crowns can be either solid or layered. Solid zirconia crowns (also called monolithic zirconia) are best used on molars. The appearance is more opaque, but the strength of solid zirconia dental crowns is good for hard chewing surfaces. Patients who grind their teeth are also good candidates for this type of zirconia crown.

Most dental practices are switching from the conventional PFM and all-ceramic crowns and moving towards the use of zirconia for creating fixed dental prostheses. Because zirconia crowns and bridges possess excellent esthetics and are virtually indestructible, zirconia is becoming the most popular material for making dental crowns and other ...
