Abstract

This article reported a case of a complicated crown fracture of an upper anterior tooth caused by trauma. During treatment, first, pulpotomy and crown reattachment were performed to preserve the vitality and morphology of the affected tooth; second, ultra-thin veneers and chair-side staining were used to increase the retention force and restore the aesthetics; finally, the tooth and pulp were preserved, and the initial morphology, color, occlusion, and adjacent relationship of the affected tooth were restored to the maximum extent. Clinical results have been stable for more than 2 years since the follow-up.
