What are the treatment goals of aligner orthodontics – Reconsidering the mandibular position

Abstract

In orthodontics, achieving a final jaw position where Centric Occlusion (CO) approximates Centric Relation (CR) is often considered ideal. However, there is no conclusive evidence that fully aligning CO and CR guarantees optimal outcomes. Aligner-based orthodontic devices, unlike traditional braces, allow teeth to be repositioned without direct occlusion, enabling easier detection of premature contacts. Despite this advantage, inadequate treatment planning can lead to significant CO-CR discrepancies upon treatment completion, resulting in unstable occlusion. This article examines cases from our clinic to illustrate treatment planning methods and explores the objectives of aligner therapy, emphasizing the need to reconsider its treatment goals for better clinical outcomes.
