ABSTRACT:
A dental implement has two moderately flexible hemostat-like handles enabling an operator to apply safely controlled force through finger and thumb grips to bring coplanar bracing and grasping beaks toward one another for gentle removal of crowns or bridges from the mouth of a patient. The bracing beak bearing on the occlusal surface of an underlying tooth is readily modifiable in length or angular position to accommodate a variety of tooth sizes, locations and orientations, and the grasping beak is hollow ground to provide enhanced purchase on a gingival margin or supramarginal notch of a crown. A method of crown or bridge removal utilizing an improved, lightweight, controlled force dental implement employs an iterative sectioning of the crown or bridge during removal.
