The routine conversation between the dentist and the patient at our Dental clinic Deccan Gymkhana Pune.
Patient:- Hey doc, why I need a crown? Only filling won’t be enough?
Dentist:- Think about the house, if you have a hole in the wall, if the hole is small then you usually spackle it with the filling but when one or two walls of house breaks, the simple filling won’t be enough, to make a strong wall to support the roof. likewise, when your tooth loses one or two walls, the filling is not enough and need to cover with the crown. Crown is like a cap which covers the entire tooth and it cemented to make tooth whole again.
Let’s talk about the different types of crowns.
Various types of crowns Deccan Gymkhana Pune
The crowns are made up of different materials. types of crowns based on its build materials are:
- Gold alloys crown.
- Nickel chromium alloys crown.
- Porcelain fused metal (ceramic) crown.
- Zirconium alloyscrown.
- Pressed ceramics/porcelain.
Gold alloys crown
In past, dentists used to fabricate the crowns with gold foil & gold alloys, as gold is malleable and mouldable. They are excellent in strength and durability. But as Dentistry advanced, the gold crown lost its demand as they are not aesthetic. There are still some patients who prefer to go for gold crowns.
Nickel Chromium Alloy Crown
For the last 40-50 years, the most popular crowns are Nickel chromium crowns ( commonly known as metal crowns ) These crowns are made by casting the custom made a wax crown with nickel-chromium alloy. They have excellent strength and durability. The disadvantages with these crowns are aesthetics and staining of gums after a few years. They are still popular among patients and we usually recommend them for posterior teeth where aesthetic is not a concern.
Porcelain Fused Metal Crown
Most commonly known as a ceramic crown. They are made up of nickel-chromium alloy fused with porcelain. The porcelain covers the metal. It is more aesthetic than the metal crown. But it requires more tooth preparation to compensate for the thickness of metal and porcelain. After a few years, the ceramic layer may chip off, leading to exposure of metal. Also, the margins of crowns are bulky and don’t look good in the aesthetic zone (front teeth).
Zirconia Crown
Zirconia is a white powder derived from a metal called zirconium. It has been in use for making dental implants since the 1990s and has now become an excellent source for dental restorations. Due to its superior strength, durability, and excellent aesthetics, Zirconia is preferred over porcelain-fused-to-metal (PMFs) by both dentists and patients worldwide also in Dental Implants Treatment.
These are newer crowns with superior aesthetics and biocompatibility. It has more strength compared to Nickel chromium crown and requires less tooth preparation. They can either be monolith or layered with ceramics.
Pressed ceramics/porcelain crown
They are commonly known as laminates. They are metal-free ceramics. These are the most conservative and aesthetically pleasant. The thickness of laminates is usually 0.3mm – 0.5 mm. They are placed on the buccal surface of teeth. mostly used in the aesthetic zone, to close the diastema and gaps between front teeth.
