Segmental archwire mechanics.
Straight wire orthodontic methods cannot treat the significant compromises demonstrated in this article. These types of patients require a three-dimensional method of correction, which involves segmental orthodontics or a modified straight wire technique. This article will discuss how to use the information gathered from a three-dimensional evaluation of the stable mandibular/maxillary relationship using a diagnostic orthotic to treat to a three-dimensional balanced relationship. Structural and functional relationships exist between the final occlusal relationship and the function of the joints, muscles and upper quadrant that must be considered during orthodontic, orthopedic and restorative finalization procedures if long term permanence is to be obtained. This article demonstrates these relationships and provides a means to approximate the dentition to function in harmony with the associated structures.
