What is a Dental Crown?

A dental crown is a full coverage restoration used when the existing tooth structure is insufficient to withstand occlusal forces or if there is extensive decay in the tooth. Dental crowns are designed to have the same contour, size, and shape as the original tooth they are replacing. After fabrication, a crown should provide the same function and esthetic outcome as the natural tooth.

Difference Between a Crown and a Veneer

Patients often ask about the differences between a veneer and a crown. There are two main distinctions:

  1. A veneer covers only the front part of the tooth, like a half crown, while a crown provides full coverage.
  2. The materials used for veneers and crowns differ, and depend on the indications for each patient.

The Dental Crown Process Getting a dental crown usually involves two visits:

  1. During the initial visit, the tooth receiving the crown is prepared by reducing its size to provide space for the restorative material. The dentist evaluates the need for additional procedures like crown lengthening or a root canal. A digital impression is taken and sent to the lab. The visit ends with placing a temporary crown.
  2. At the second visit, the temporary is removed and the final crown is cemented. The dentist checks interproximal contacts, marginal fit, and adjusts the occlusion. An X-ray verifies proper fit.

Materials Used for Dental Crowns

Various materials are used to fabricate dental crowns, each with advantages and indications:

  • Temporary crowns are commonly made of PMMA plastic or other resin materials.
  • Gold crowns excel in biocompatibility and longevity but are limited to posterior teeth due to cost and esthetics.
  • Porcelain fused to metal (PFM) crowns have a metal substructure covered with tooth-colored porcelain. They are a gold standard with a great track record.
  • Zirconia crowns, made of zirconium dioxide, combine esthetics with durability. They suit patients with bruxism who develop high posterior forces.
  • Emax crowns made of lithium disilicate provide the best esthetics and translucency for anterior teeth. They require a more technique-sensitive bonding process.

Maintenance and Complications

With a skilled practitioner and master technician, crowns can last 15+ years. The abutment tooth’s integrity and remaining tooth structure are key for longevity.

Potential complications include the possible need for a root canal due to sensitivity during tooth preparation, or porcelain chipping from unsupported design or incorrect material selection.

The dentist’s correct diagnosis is critical for choosing the ideal restoration and material. From the patient’s side, daily oral hygiene and regular preventive dental visits ensure long-term success.
