Introduction to Full Coverage Crowns

Full coverage crowns are restorative dental procedures that replace the entire visible portion of a tooth.
They are used to restore severely damaged, decayed, fractured, or weakened teeth.
The restoration aims to improve the tooth's strength, aesthetics, and function.

Reasons for Full Coverage Crowns

Severe decay or damage: Extensive decay that compromises the structural integrity of the tooth.
Fractures: Cracks or chips that extend into the tooth's structure, compromising the tooth's strength.
Root canal therapy: A necessary treatment to protect the remaining tooth structure after a root canal.
Severe wear: Excessive wear from grinding or bruxism, making the tooth susceptible to further damage.
Significant misalignment: In some cases, misaligned teeth can benefit from a full coverage crown as it can facilitate better alignment and bite.
To support a dental bridge: Crowns can provide a foundation for bridges, in cases where the bridge is needed on a missing tooth.
Improve aesthetics: Full coverage crowns can significantly improve the appearance of a tooth that is discolored or misshapen.

Materials Used for Full Coverage Crowns

Porcelain-fused-to-metal: A popular choice for its strength and durability. A metal substructure supports a porcelain veneer.
All-ceramic (porcelain): Biocompatible with natural teeth, offering improved aesthetics. Strong and durable depending on the specific ceramic material used.
Gold alloy: A strong and durable option, less prone to discoloration compared to other metal choices.
Zirconia: A strong and hard ceramic material with excellent aesthetic and strength properties, making it resistant to chipping and stains.

Procedure for Full Coverage Crown Placement

Initial examination and diagnosis: Comprehensive evaluation of the tooth's condition and assessment of the patient's oral health. Diagnostic x-rays and/or 3D scans may be involved.
Preparation of the tooth: Removal of damaged or decayed tooth structure. Precise shaping of the tooth to allow for a proper fit of the crown. This process involves anesthesia, generally involving local anesthetic.
Impression taking: Creating a mold of the prepared tooth to produce a model for the custom crown. Digital impressions are becoming increasingly common.
Temporary crown placement: A temporary crown is placed to protect and support the tooth during the time the permanent crown is being fabricated.
Crown fabrication: A dental laboratory crafts the permanent custom-made crown based on the impressions and model.
Fitting and cementation: The crown's fit is carefully checked, and the permanent crown is cemented to the prepared tooth. The dentist ensures proper placement and bite relations.
Follow-up appointments: Regular check-ups are needed to monitor the crown's fit and function and make sure there are no issues with sensitivity, or other reactions.

Considerations for Full Coverage Crowns

Cost: Full coverage crowns can be expensive, varying based on the material used and the complexity of the procedure.
Potential for sensitivity: Some patients may experience temporary tooth sensitivity after the procedure.
Long-term maintenance: Proper oral hygiene and regular dental check-ups are essential to maintain the longevity of the crown.
Allergies: Patients with metal allergies should discuss alternative materials with their dentist.
Suitable for various patients: Suitable for individuals of diverse ages and backgrounds who need to restore or replace a damaged tooth.

Aftercare for Full Coverage Crowns

Maintaining good oral hygiene: Brushing, flossing, and using mouthwash are crucial to prevent gum disease.
Following up on checkups: Ensuring that the crown fits well and that any problems are detected and addressed in time.
Avoiding hard or sticky foods: Avoid causing stress or damage to the new crown through strenuous foods or pressure.
Identifying and addressing any discomfort: Communicating with the dentist about any sensitivity, pain, or issues with the crown.
