Resin Wing Technique With Sandblasting Interface Modification: A 24‐Month Stable Pulp Preservation in Young Permanent Teeth With Complex Crown Fractures

Pulp preservation combined with fragment reattachment represents an optimal approach for managing complex crown fractures in young permanent teeth. The resin wing technique improved repositioning precision and reduced technical sensitivity, enabling efficient case completion. Nevertheless, case selection-considering factors such as functional support of adjacent teeth-is critical for technique applicability.
