ABSTRACT:
A dental crown form or strip crown for holding and shaping a body of composite resin material being applied to an anterior tooth requiring restoration. The crown form is a thin hollow body with an interior surface conforming to the shape of a natural tooth. A tab is integrally formed at the base or gingival end of the crown form, and the tab extends away from the base to provide a gripping handle for the crown and a surface for displaying a designation of the tooth of intended use. A flange is integrally formed around the base to strengthen and rigidify the crown form which is preferably made of co-polyester plastic.
