Zirconia Discs and Crowns – Perth Dental Lab
In the past, only two options were available for teeth crowns: gold-based crown or a porcelain fused to metal (PFM) crown. However, these traditional options came with their own set of problems.
Gold-based crowns are sturdy and malleable enough to allow dental lab technicians to achieve a precise crown-to-tooth fit, could be aesthetically unpleasing for some individuals, thus were used mostly for posterior teeth.
Porcelain Fused to Metal Crowns (PFM)
On the other hand, PFM crowns, while being aesthetically appealing enough for anterior and posterior teeth, caused teeth to wear, chip and showed metal at the edge of the crown.
This is why the zirconia discs and crowns have been received by much favour by dental lab
technicians and dentists alike. Zirconia discs and crowns have been a choice recommendation of PMC – Perth Dental Lab because it combines the best of both gold-based crown and PFM crown minus their shortcomings. Our dental technicians at PMC prefer zirconia not only because of its highly aesthetic results but also because zirconia disc helps achieve a natural tooth appearance, making it
ideal for anterior and posterior teeth alike. This is because zirconia has a naturally translucent nature which reflects the colour of the adjacent teeth and comes in a variety of shaded, increasing the possibility of finding the exact shade to match the patient’s natural teeth
Zirconia is durable as well as compatible enough with the teeth that zirconia crowns
can be safely used without any fear of side effects or allergic reactions. Made from a long-lasting and indestructible material, zirconia crowns are also easy to wear on tooths that have been chipped, stained or disfigured over time. Moreover, zirconia crowns are fixed so that the original tooth is preserved, which can come in handy if there is a need to remove the crown for any reason.
