Cast modification for immediate complete dentures: Traditional and contemporary considerations with an introduction of spatial modeling

Cast modification procedures associated with immediate denture therapy have been primarily anecdotal. Recommendations have been based upon expert opinion and clinical experience. While these recommendations have been useful, the growing body of evidence-based information permits new opportunities such as spatial modeling. In this instance, spatial modeling was used to plan and execute a series of cast modifications central to the immediate denture fabrication process. Modeling was based upon accepted norms from the dental literature. The model supported development of a predictive cast modification technique intended to minimize the binding of denture bases, decrease the necessity for osseous recontouring, and enhance clinical efficiency.
