A dental implant is an artificial tooth root. One or more implants can be used to support a variety of different types of dental restorations. These include: crowns, bridges, partial dentures, and complete dentures. As part of the planning process for implant treatment, models, x-rays, and photographs are taken so that we can best restore function and esthetics. If you have a missing tooth (or teeth), your dentist will discuss the various options for replacement.
