title: The Dahl principle: creating space and improving the biomechanical prognosis of anterior crowns.
abstract: There is an increased demand for restoration of anterior teeth based on esthetic requirements. Oftentimes, the teeth restored are compromised and have minimal remaining dentin after undergoing root canal treatment. Reduction of nonaxial forces by controlling incisal guidance is essential in improving the long-term prognosis of such situations. Another common complication when crowning anterior teeth is the lack of palatal space for restorative material. This is often evident in patients with anterior tooth wear and deep overbite. This article describes the Dahl principle, a conservative method for controlling incisal guidance and gaining palatal space for restorative material. A case presentation is used to illustrate the concepts discussed.
