Application of Dahl’s principle in severe hypodontia patient: a clinical report.

Abstract

One of the biggest challenges in management of severe hypodontia cases is the inadequate space for restorations. Increasing the occlusal vertical dimension (OVD) using conventional prosthodontics can be aggressive, technically challenging and accompanied with high maintenance. Application of Dahl's principle to create space is well-documented and is commonly applied in tooth wear patients. To date, there is no evidence to use Dahl's principle in severe hypodontia patients. However, with the signs of dentoalveolar compensation, Dahl's concept should be considered at an earlier stage to increase OVD due to its conservative nature. This article illustrates and provides a detailed description regarding this technique to create the restorative space for implant supported restorations.
