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

摘要

Cast modification for immediate complete denture applications .has been based largely upon the recommendations of a few authors. While helpful, these recommendations are primarily subjective. This article reviews 2 long-standing methods for cast modification and, subsequently, introduces the concept of spatial modeling. Spatial modeling involves the application of anatomic norms -to gain an improved understanding of oral tissues and their dimensional relationships. A cast modification process based upon spatial modeling is described. The foregoing cast modi-ficationVnethods are then compared. Indications and contraindications for the respective techniques are presented.
