An analysis of orthodontic force systems applied to the dentition with diminished alveolar support.
Many more adults are undergoing orthodontic therapy than in the past. Since adult dentitions often exhibit diminished alveolar support, it is important to recognize the related apical migration of the dental centre of resistance when applying force systems to the teeth. The force system compensations necessary to produce controlled movement in this circumstance are analysed in a model of a maxillary canine undergoing translation.
