Functional occlusion after orthodontic treatment is a controversial subject. However, the literature considers acceptable a set of requirements including maximum intercuspation coincident or very close to the stable condylar position; stable, bilateral, and symmetrical occlusal contacts; absence of contacts in mediotrusion; no posterior contacts in protrusion and group function or canine guidance in the working side. Clinical procedures in evaluating these requirements are limited because they cannot assess bilateral balance of forces, nor the force delivered by each tooth, nor quantify functional parameters such as occlusion and disclusion time. Dynamic occlusal events can be quantified by using T-Scan III system, which provides progressive real-time information that is very helpful in performing occlusal adjustment procedures.
