Pure zirconia dental crowns – the strongest material for crowns

Zirconia crowns are dental prostheses indicated for restoration and dental rehabilitation in people who have had damage to one or more teeth. Rehabilitation with dental crowns aims to restore the aesthetics and functionality of the smile, improving not only chewing, the appearance of the teeth, but also self-esteem.

Zirconia crowns: excellence for aesthetic results

However, some materials used to make dental crowns are not strong enough to be used in patients suffering from bruxism. As is well known, bruxism is a disorder of oral function movements, characterized mainly by involuntary grinding or clenching of the teeth.

It occurs mainly during sleep. This excessive load on the teeth and musculoskeletal structures of the face can cause problems with the teeth and correct occlusion in general.

Although the cause of bruxism is not very clear, it is certain that this condition most often affects people who suffer from emotional problems, such as stress, anxiety and excessive worry.

Just as the excessive force generated by bruxism can wear down teeth, it can also damage dentures made of certain materials.

In these cases, our team has the option of recommending porcelain crowns with a pure zirconia internal structure, which are proven to be more resistant and can withstand a greater load, even in patients with bruxism.

Zirconia acquires this strength because it goes through a controlled process called sintering, which is heating it at a high temperature in a special furnace. This process modifies its particles, creating a solid and very strong prosthetic piece. Other properties of crowns with a pure zirconia structure:

• Metal free crown
• Translucency – even in very bright environments
• Biocompatibility – no risk of rejection
• No cold or heat conductivity
• They can be screwed or cemented onto implants

How do I know if I can have a crown with pure zirconia even if I have bruxism?

First of all, it’s important to assess the degree of oral impairment that bruxism has caused so far. If you have untreated bruxism for many years, there may be advanced wear of the dental crowns and/or root fractures.

Therefore, before receiving prosthetic crowns to rehabilitate and restore your smile, you will probably need to undergo treatment to correct these defects (e.g. root canal treatments, vertical dimension increase, clinical crown increase). Dr. Markarian, our general manager, saysthat controlling bruxism is essential to avoid future problems and porcelain crowns with a pure zirconia structure may be indicated.

ImplArt Odontologia has its own dental laboratory with the Cerec 3D, Cerec Primemill, Trios 3Shape and Ceramill systems, which speed up the fabrication of crowns with pure zirconia and metal-free ceramics, in some cases even in just a few hours in an ImplArt Day Clinic or Dental Spa, where you can carry out the largest number of dental procedures in just one appointment or in just a few days. This way, patients can set aside a day in their schedule or a few days in a week to dedicate to dental treatment, without it taking months to complete.
