Old metal fillings can lead to cracks in the teeth. These cracks become prone to decay. When there is too much tooth structure lost, crowns can be a solution for restoring the form and function. More pressure is applied on the back teeth when chewing , so crown restorations were used for stability and strength.
Fractured Alloy Fillings with Recurrent Decay
Procedure Details
This patient presented with existing broken down large silver fillings with cavities around them. Due to the size of the previous fillings the area was treated with Zirconia crowns. Zirconia is a very strong all porcelain material. With no metal being used, there no darkness visible around the margins, which can be healthier for the surrounding gums.
