What is a term used to describe a full set of artificial teeth designed to replace natural teeth?

The term that describes a full set of artificial teeth designed to replace natural teeth is "denture." Dentures are removable appliances that can restore both function and aesthetics for individuals who have lost their teeth due to reasons such as decay, gum disease, or injury. They can be complete (replacing all teeth in the upper or lower jaw) or partial (replacing some missing teeth while natural teeth remain).

Implants refer to surgically placed titanium posts that act as roots for replacement teeth and are not a complete set of artificial teeth themselves. A retainer is typically a dental appliance used to maintain the position of teeth following orthodontic treatment, not for replacement. A crown is a type of dental restoration that caps a tooth to restore its shape, size, strength, and appearance but does not involve replacing an entire set of teeth. Thus, dentures is the appropriate term for a full set of artificial teeth.
