Types of crowns available for crowns and bridges
Porcelain crowns are made up of porcelain or silica, material similar to vases and clay pots.
Advantages of Porcelain fused to metal crowns
- PFM crowns are the best choice for crowns if aesthetics is not a concern as there is a metal layer beneath the porcelain which differentiates it from the aesthetic metal free crowns.
- Long term prognosis and durability are well established
- Available at an affordable price
Disadvantages of Porcelain fused to metal crowns
- Aesthetics of porcelain free crowns is greater than PFM crowns
- Grey line is visible at the gums due to the presence of metals beneath the porcelain
E-MAX crowns are made from lithium desilicated ceramic, which is known for its translucent colour and durability. As a result, you get a naturally looking crown that is tough and durable and matches with the remaining teeth in your mouth.
Advantages of E-Max crowns

What procedures are involved in making a crown and Bridge?
- An initial assessment is done with the help of a radiograph
- Based on the findings of the radiograph any underlying decay is taken care of with the help of fillings or Root canal treatment as required
- First visit for the crown or Bridge
- Initial shaping of the crown/crowns is done based on the type of the crown selected
- Impression is taken with the help of latest materials (Putty) for accurate details that will be helpful during fabrication of the crown/bridge in the lab. The dentist may also take a digital impression
- Shade selection is done wherever applicable to ensure the colour of the crown matches with the shade of the existing teeth in the mouth
- The impression is then sent to the Dental lab for fabrication of the crown/bridge and the patient is called for a subsequent visit in 2-3 days. This may vary from case to case
- Second visit for the crown
- During this visit the dentist will check the fit, size and shape of the crown/bridge
- He may check the shade as well in this visit if the crown is metal free or may call the patient for another visit
