Which term refers to artificial replacements for lost teeth?

The term that refers to artificial replacements for lost teeth is dentures. Dentures are custom-made appliances designed to replace missing teeth and can be either full or partial, depending on how many teeth are absent. They help restore function for eating and speaking, and also provide aesthetic benefits by filling out the appearance of the face.

In the context of the other choices: implants refer to a specific type of dental procedure that involves surgically placing a post in the jawbone to support a crown or bridge, thus serving a different purpose. Fillings are used to restore teeth that have cavities and do not replace lost teeth but rather maintain those that are still present. Braces are orthodontic devices used to straighten and align teeth, but they do not serve as replacements for teeth that have been lost. Understanding these distinctions emphasizes why dentures are the correct term for artificial replacements of lost teeth.
