What does the term "cortical plate" refer to in dentistry?

  1. The soft tissue around the teeth

  2. Outer bone layer growth of alveolar bone

  3. The inner surface of the jawbone

  4. The covering of the tooth root

The correct answer is: Outer bone layer growth of alveolar bone

The term "cortical plate" refers to the outer layer of compact bone that forms part of the alveolar bone, which houses the sockets for the teeth. This structure is crucial for providing support to the teeth and maintaining the overall integrity of the jawbone. It is dense and strong, facilitating the proper function of the teeth during biting and chewing. The cortical plate serves as a protective barrier and is essential in dental procedures, particularly in surgeries involving implants or extractions, since it must be carefully considered to avoid damage during these interventions. Understanding this term helps dental professionals assess bone quality and make informed decisions about treatment plans, particularly those involving dental implants or bone grafting.
