Dental Crowns – IPS e.max vs. traditional PFMs (Porcelain-Fused-to-Metal)
There are some great dental innovations with dental crowns. Dental crowns are often the best answer for deep-stained, damaged or deformed teeth. They go over teeth to recreate new and improved smile. It all starts with a precise mold, whether traditional mold or digital one. Often, patients are fitted with a temporary crown while they wait for the permeant one to be designed in the lab by the qualified lab technician.
There are 3 types of crowns:
- gold alloy (mixture of gold and other metals)
- ceramic metal mix (so called PFM crowns)
- all ceramic (IPS e.max and zirconia)
Gold crowns are the most expensive and least esthetic type of a crown. Usually they are only used in the back of the mouth, if at all today.
PFM crowns are considered the traditional crown. They are on the way out since they tend to chip off and porcelain tends to fracture off exposing the metal making them un-esthetic and weak. They are the old technology and due to poor esthetics are now sparingly used.
All-ceramic crowns are highly esthetic, and their strength far exceeds strength of veneered porcelain in the old PFM crowns. IPS e.max is lithium disilicate type of crown and have moderate strength. Zirconia crowns are not as esthetic but are very strong type of a crown, usually used in the back of the mouth due to their strength.
IPS e.max Crowns & Zirconia Crowns
When the right kind of tooth preparation design is done by your dentist (smooth preparation design with no sharp corners or angles), these kinds of crowns can last a very long time. They are also highly esthetic. Zirconia crowns are the strongest crown we have and strides have been made to make them more esthetic. Zirconia is now used not only for crowns on the teeth but also on implants. Zirconia is also being used for hybrid prostheses on implants and has shown superior esthetics.
