Which term describes a structure that serves to replace a missing tooth?

The term that accurately describes a structure designed specifically to replace a missing tooth is "implant." An implant is a surgical fixture that is placed into the jawbone and serves as a stable foundation for a replacement tooth or teeth. The implant itself is typically made of biocompatible materials, and over time, it fuses with the bone in a process called osseointegration. This provides an effective and durable solution for tooth loss, allowing for the attachment of crowns, bridges, or dentures on top of the implant.

While a bridge is used to replace one or more missing teeth by anchoring to adjacent healthy teeth, it does not involve the jawbone directly. A crown is a restorative cap placed over a tooth to restore its shape, size, strength, and appearance, and does not serve to replace a missing tooth. An inlay is a type of restoration used to repair a damaged tooth, often filling in cavities, and is not applicable for replacing a missing tooth either.
