Posterior Zirconia Crown

Zirconia Posterior Crown

A zirconia posterior crown is a specially fabricated cap that covers the damaged or weakened molar or premolar giving it its shape, strength and function. Zirconia crowns differ from standard metal crowns which are metal-made and are not biocompatible or integrated with natural teeth. Zirconia crowns are metal-free, biocompatible and integrated with natural teeth unlike the traditional metal-made crowns. These crowns are often recommended for people who require a restoration that will last a long time as it is able to withstand everyday chewing and grinding.

Who Needs a Zirconia Posterior Crown?

Your dentist may recommend a zirconia posterior crown if you have:

• A tooth that has been severely decayed and cannot be filled with a tooth filling.
• A damaged back tooth that has cracked or fractured.
• A tooth that has been treated for the decay of the tooth root.
• A worn down tooth caused by grinding (bruxism)
• A filling that compromises the remaining tooth structure.
• An implant in the back part of the mouth.
• A fractured or fractured tooth which needs full coverage.

Zirconia Posterior Crowns offer numerous benefits

Zirconia crowns have several benefits:

• Excellent strength and fracture resistance
• Long-lasting durability
• Natural tooth-colored appearance
• Metal-free and biocompatible
• Wear and corrosion resistant
• Minimises allergens
• Ideal for patients with strong bite forces
• Smooth surface prevents the accumulation of plaque.
• Easy and comfortable eating for all day meals.

Zirconia crown for posterior teeth

A zirconia crown is the custom-made cap that is made using a very strong ceramic material, zirconium dioxide. It fully encases a broken or compromised back tooth, regaining its shape, function and strength and seamlessly integrates with the surrounding natural teeth. With modern zirconia crowns, there are two types: a monolithic (all zirconia) and a layered zirconia crown, both of which are both durable and aesthetically pleasing.

Why Are Zirconia Crowns Ideal for Posterior Teeth?

The most biting and chewing forces are present in the posterior teeth. Zirconia crowns are especially recommended due to the following properties:

• High fracture resistance
• Excellent wear resistance
• Long-lasting durability
• Natural-looking appearance
• Metal-free restoration
• Excellent biocompatibility
• The ability to resist staining and corrosion.
• Resistance to intense chewing forces.

Types of Zirconia Crowns

Monolithic Zirconia Crowns

• The advantage of these crowns is that they are both single unit of zirconia and provide maximum strength which is appropriate for back teeth.

Layered Zirconia Crowns

• The advantage of these is that they have a zirconia core that is encased in porcelain for better aesthetics yet they have a great durability.

A crown procedure using zirconia

• Typically, there are two dental visits to follow this process.

Initial Consultation

• Using clinical examination and dental X-rays, the dentist will assess the affected tooth to see if a crown is needed.

Tooth Preparation

• The damaged or decayed area of the tooth is removed and the tooth is reshaped to fit the crown.

Dental Impression

• An impression or digital scan of the tooth/teeth to be prepared is made and sent to a dental lab for making.

Temporary Crown

• A temporary crown can be used to maintain the integrity of the tooth until the permanent zirconia crown is fabricated.

Permanent Crown Placement

• After preparing the zirconia crown, the dentist then checks how it fits, how it looks and how it fits together with another tooth before it is permanently cemented in place.

Recovery After Zirconia Posterior Crown Placement

• Recuperation is fast and uncomplicated in general.
• Mild sensitivity may be experienced for a few days.
• For the first 24 hours do not eat sticky or hard foods.
• Carefully clean around the crown with brush and floss.
• Get regular dental examinations.
• If you grind your teeth, wear a night guard.
• Most patients will resume normal diet in one to 2 days.

Conclusion

A posterior Zirconia crown is an ideal choice for damaged and weak molars and premolars and provides excellent strength, durability and natural appearance. Zirconia crowns are incredibly well suited to the occlusal forces applied by the back teeth and therefore offer long lasting protection and maintain the function and aesthetics of the tooth. A posterior zirconia crown provides stable performance and requires minimal maintenance whether it's after the root canal replacing a fractured tooth or replacing a large filling. It can last for many years with the proper oral hygiene and regular dental visits and can deliver comfortable, functional and attractive results.
