For patients with severe ridge atrophy, what should be noted about the maxilla and mandible?

The assertion that the maxilla is usually narrower in patients with severe ridge atrophy is correct and aligns with anatomical observations. Ridge atrophy often results in significant bone loss in both the maxilla and mandible; however, the maxilla is typically more affected in terms of its width.

In cases of severe ridge atrophy, the maxillary arch may demonstrate a constricted shape, which can lead to a narrower base. This phenomenon is particularly relevant in patients who have experienced significant resorption of bone following the loss of teeth, as well as in those with long-term edentulism. This narrowness can lead to functional issues with dental prosthetics and is a crucial consideration when planning for implant placement or other restorative procedures.

Understanding this anatomical relationship is important for dental professionals involved in surgical planning, prosthetic design, and orthodontics, as it helps inform the choice of treatments and potential outcomes for patients.
