Zirconia Crown v/s Metal Ceramic Crown

Date :11-Dec-2020

A dental crown is a custom-made cap-like structure that is placed over the natural tooth, designed to replace missing teeth, provide strength to the teeth after a root canal treatment or to correct the shape of the teeth. The most popular type of crowns available today are Zirconia and metal ceramic crowns (PFM crowns). Let us understand the basic difference between the two in the following terms:

Material: Zirconia is made up of tiny white crystals called zirconia crystals which are often referred to as ‘white gold.’ Metal ceramic crowns are made of porcelain fused onto a metal base.

Strength: Although both the types are strong enough to be placed in any area in the mouth, Zirconia Solid has more strength when compared to PFM. Zirconia is recommended for patients who have grinding problems due to its incomparable strength.

Comfort: Both are easy to use and comfortable. Zirconia does not transmit temperature fluctuations to the natural teeth. Thus, it has no risk of hypersensitivity because they are resistant to hot and cold.

Biocompatibility: Metal ceramic crowns may sometimes cause soft tissue irritation but zirconia is highly biocompatible and does not cause allergies.

Maintenance: Regular brushing and flossing is required for metal ceramic crowns just like natural teeth. Zirconia crown has an advantage of being very effective in reducing the presence of plaque and tartar accumulations due to its smooth surface.

Aesthetics: Metal ceramic is resistant to stains and discoloration but over time the gum tissue may recede to expose the metal margin. This creates a grayish line along the margin of the teeth and gums. Zirconia has the closest resemblance to natural teeth and there are no aesthetic concerns.

The choice of crown may differ for each individual based on their health conditions and anatomical considerations. Our dentists analyse your requirements and concerns to suggest you the best for your treatment.
