ABSTRACT
This article presents an overview of the evolution of the incisal edge reattachment procedure. Case reports are described of patients presenting with traumatised teeth in which the reattachment procedure was performed. A review is provided of present in vivo studies detailing long-term success rates in the clinical application of this procedure. Finally, a recommended technique for diagnosis and treatment is offered to improve success in this procedure which may benefit a significant segment of the paediatric and adolescent populations.

OBJECTIVE: This study evaluated the effect of preparation utilization and design, and addition of resin composite to the bonding interface, on the fracture resistance of reattached incisal fragments. METHOD AND MATERIALS: Sixty bovine incisors were distributed among 1 control group and 5 experimental groups. Experimental specimens were sectioned 3.0 mm from the incisal edge with a 0.15-mm wafering blade at a 25-degree inclination apically in a faciolingual direction. Two groups received no further preparation. Specimens in the other 3 groups received either external bevels, internal bevels, or combined external and internal bevels. One preparationless group was reattached with dentin bonding agent alone. All other fragments were reattached with a dentin bonding agent-resin composite interface. After thermocycling and 4 weeks of bond weathering, specimens were sheared to failure in a universal testing machine. RESULTS: No significant differences in fracture strength were observed among any of the experimental groups, yet each displayed significantly less resistance to fracture than the control group. Reattachment of fragments in all groups restored approximately one half or one third the fracture strength of the control teeth for crown or root fractures, respectively. CONCLUSION: Compared to the simple, expedient regimen of using a dentin bonding agent alone, nonconservative tooth modification and the addition of resin composite to the bonding interface did not increase resistance to fracture and thus provided no retentive advantage.

Anterior crown fractures in children and adolescents are a common form of injury, affecting approximately 25% of that population. Common restorative treatments such as composite bonding, laminate veneers, or full-coverage restorations tend to sacrifice healthy tooth structure and challenge dentists to match the adjacent unrestored dentition. Incisal edge fragment reattachment, including the use of current bonding techniques, is a restorative treatment option that offers the advantages of simplicity, immediate esthetics, and conservatism in cases of dental trauma. This article presents a comprehensive literature review on this restorative technique. It also provides diagnostic and treatment algorithms to simplify and clarify the recommended diagnostic and clinical regimens.
