Which portion of the ridge replaces the missing tooth?

Abutment
Pontic
Connector
Retainer

The correct answer is: Pontic

The correct response refers to the "pontic," which is the artificial tooth that occupies the space of a missing tooth in a dental bridge. It is designed to replicate the appearance and function of a natural tooth. The pontic is anchored by the abutments, which are the natural teeth on either side of the gap. Understanding the role of the pontic is crucial in restorative dentistry because it not only helps to restore the aesthetic appearance of a smile but also plays a significant role in maintaining the alignment of remaining teeth and supporting oral function, such as chewing. Properly designed pontics can help prevent the shifting of adjacent teeth and can contribute to overall oral health. The other choices represent components of a dental bridge but do not directly replace the missing tooth themselves. The abutment is part of the structure that supports the pontic, the connector refers to the part that links the pontic and abutments together, while the retainer is often associated with securing the bridge to the abutment teeth. Each serves an important role in the overall integrity of the prosthesis, but it is the pontic that specifically replaces the missing tooth.
