What does edentulous arches mean?

Edentulous arches refer specifically to a condition in which no teeth are present in the dental arch. This situation can occur in either the upper or lower jaw and can result from various factors, such as dental disease, injuries, or aging. Understanding the term "edentulous" is essential in dental practice, especially in relation to treatment planning for dentures or other prosthodontic work, as it signifies the complete absence of natural teeth in an area. Treatments for edentulous patients typically focus on restoring function and aesthetics through the use of dentures or implants.
