Essentials of rebonding tooth fragments for the best functional and esthetic outcomes

Crown and crown-root fractures of anterior teeth of children are common. Bonding of the crown fragment is a logical restorative treatment option when the trauma results in no or minimal violation of the biological width and when the crown fragment: (1) is retrieved following the trauma; (2) is relatively intact; and (3) adopts well to the remaining tooth. Reattachment of crown tooth fragments can provide favorable and long-lasting esthetics because the tooth's original anatomic form, color, and surface texture are maintained. Reattachment also restores function, provides a positive psychological response, and is a relatively simple procedure. The clinician, however, should clearly inform the patient about the limitations and prognosis of this treatment option. The purpose of this paper is to summarize the current knowledge about crown fragment reattachment and present recommendations for the best functional and esthetic outcomes. The rebonding technique is illustrated in detail with a clinical case report.
