ABSTRACT:
A dental scaler particularly for scaling artificial dental abutments made of a material that is softer than natural dentition, such as titanium and its dilute alloys, without scratching the surface of the abutment. Two embodiments of the scaler are disclosed; in one the scaler tip has a contact surface that is softer than the abutment surface; in the other the contact surface has a contact edge that is rounded to avoid scratching the abutment surface.
