Instrument for removing a dental crown |
摘要 |
An instrument for removing a crown by generating a couple of forces between the occlusal surface of the stump of the tooth and the basal surface of the crown. The instrument has an indented intermediate portion and a working part extending from a tapered intermediate portion and a handle. When inserted in a groove formed at the occlusal part of the stump along a plane substantially parallel to the occlusal surface of the crown, the working portion enables, by a physical action, exertion of a couple of forces between the respective occlusal surfaces of the stump and the basal surface of the crown. The working part is rotatable integrally and correspondingly with a rotation of the handle. |
