摘要：

本文报道了1例因外伤导致上前牙复杂冠折的病例。治疗过程中，首先对患牙行牙髓切断、断冠粘接术，实现了患牙牙髓活力、牙体形态的保存；其次配合数字化技术制作贴面、椅旁外染色技术，增加患牙的固位力及恢复美观；最终实现患牙牙体、牙髓的保存，最大程度恢复了患牙初始形态、颜色、咬合、邻接关系等特征。随访2年多以来，临床效果稳定。

关键词: 复杂冠折, 牙髓切断术, 数字化技术

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.

Key words: complicated crown fracture, pulpotomy, digital technology
