A full coverage crown is a method of replacing or strengthening the coronal structure of a severely damaged tooth.
It essentially covers the entire part of the tooth that is above the gums. Usually, a grossly decayed tooth can be restored back to its original form and function by placing a crown on top of it.
Include a post endodontic restoration, that is covering the tooth after an RCT has been done. Since, a tooth is hollow after RCT and the coronal tooth structure is only filled with a restorative material, the crown helps to hold the walls of the tooth together so that it can withstand the heavy masticatory or chewing forces.
It can also be used to make aesthetic corrections in a situation where a tooth is severely discoloured, and simple bleaching or laminates are not good enough to achieve the desired results.
Regardless of the material you choose for your crowns, it is very important to note that all crowns are safe with the MRI machine.
The MRI machine uses a magnetic field to create a radiographic image of hard and soft tissues of your body. Please note that any metal used to fabricate crowns essentially are NON – MAGNETIC. Hence, if you have Porcelain Fused to Metal (PFM) crowns in your mouth, rest assured they will not interfere with the MRI machine causing any damage to your body.
