What constitutes an artificial crown?

  1. A restoration that covers the entire anatomy of the tooth

  2. A removable device for replacing teeth

  3. A bonding material for chipped teeth

  4. A temporary filling material

The correct answer is: A restoration that covers the entire anatomy of the tooth

An artificial crown is defined as a dental restoration that completely encapsulates the exterior surface of a tooth, effectively covering its entire anatomy. Crowns are typically used to restore teeth that are significantly damaged due to decay, fracture, or other dental issues, allowing them to regain their form and function. This restoration is crafted to mimic the natural appearance of teeth and can be made from various materials, including porcelain, metal, or a combination of both. In contrast, other options refer to different dental devices or materials that do not encompass the whole tooth structure. A removable device is generally used for replacing missing teeth and does not cover the tooth completely like a crown does. The bonding material for chipped teeth is typically applied to repair the visible part of a tooth but does not provide the same full coverage and structural support as a crown. Temporary filling materials serve short-term purposes for cavities, rather than offering a comprehensive restoration for the anatomy of a tooth. Thus, the definition of an artificial crown is aptly captured by the description of a restoration that covers the entire anatomy of the tooth.
