Restorative Management of Constriction and Spacing Following Arch Expansion.

Patients presenting for esthetic improvement due to progressive tooth wear or after orthodontic treatment may have underlying functional constraints that, if left unresolved, could lead to discomfort and long-term disability. To achieve predictable outcomes, clinicians must identify any potential functional limitations and develop a treatment plan that respects biologic boundaries. This case report illustrates how a structured diagnostic approach rooted in established systematic principles revealed a persistent constricted chewing pattern following orthodontic expansion. By addressing the functional etiology rather than focusing solely on tooth position, a comprehensive treatment plan was able to be developed to improve comfort, restore function, and enhance esthetics in a stable and conservative manner.
