Dental crowns, commonly referred to as "braces" in some contexts, are dental prosthetics used to restore and protect damaged teeth. They are primarily used to repair teeth affected by decay, wear, cracks, or other issues, helping to restore both function and appearance.

Types of Dental Crowns

● All-Porcelain Crowns: Made entirely of porcelain, these crowns provide the best aesthetic results as they closely resemble natural teeth. They are good biocompatibility and typically recommended for front teeth.

● Porcelain Fused to Metal Crowns: These crowns have a metal base for strength and a porcelain outer layer for aesthetics. But over time, it may show dark edges at the gum line over time because the metal substructure may become visible. This can detract from the aesthetic appeal.

● Metal Crowns: These crowns are durable and can withstand significant biting forces, making them suitable for back teeth. They are typically made from alloys or gold. While they may not be aesthetically pleasing, their strength makes them a reliable choice for molars.

Indications for Use

1. Severe Tooth Decay: When a tooth is too damaged by decay to be repaired with a filling.

2. Cracked Teeth: Teeth with cracks that need protection.

3. Post-Root Canal Treatment: Teeth that have undergone root canal therapy often require crowns to restore strength.

4. Congenital Enamel Defects: Some individuals may have insufficient enamel from birth.

5. Discoloration or Staining: Conditions like tetracycline staining may require crowns for aesthetic improvement.

6. Irregular Tooth Shape: Teeth that are misshapen may need crowns for restoration.

Crown Fabrication Process

The process of getting a dental crown typically involves several steps:

1. Assessment and Preparation: The affected tooth is evaluated, and any necessary adjustments are made to create space for the crown.

2. Impression Taking: An impression of the tooth is made using traditional molds or 3D scanning technology to create an accurate model.

3. Temporary Crown Placement: A temporary crown may be placed while the permanent one is being fabricated.

4. Fitting and Cementation: Once the permanent crown is ready, it is tried on for fit and aesthetics before being permanently cemented onto the tooth.
