The purpose of this case presentation is to review the rationale for and illustrate the clinical procedures involved in intentional replantation of a maxillary central incisor following a complicated crown-root fracture. The treatment of complicated crown-root fractures in children often is compromised by a fracture below the gingival margin and/or bone. This makes isolation difficult and comprises the hermetic seal that is critical for a successful endodontic treatment. Orthodontic or surgical extrusion with gingivectomy has been suggested; however, these approaches can be expensive, time-consuming, esthetically compromising, and unsatisfactory when the fracture line is deep below the gingiva. Our presentation will discuss the treatment options for such cases and introduce the concept of intentional replantation as an option to manage complicated crown-root fractures in young permanent anterior teeth.
本病例报告的目的是回顾复杂冠根折后上颌中切牙意向性再植的理论依据，并阐述其临床操作过程。儿童复杂冠根折的治疗常因骨折线位于龈缘以下和/或骨内而受到影响。这使得隔离困难，并影响了对成功进行牙髓治疗至关重要的严密封闭。有人提出正畸或手术牵引并切除牙龈；然而，当骨折线位于牙龈深处时，这些方法可能成本高、耗时、影响美观且效果不理想。我们的报告将讨论此类病例的治疗选择，并介绍意向性再植的概念，作为处理年轻恒牙上前牙复杂冠根折的一种选择。
