Abstract: Objective To observe the clinical effects of Super-bond C&B interproximal bonding on fixing anterior teeth traumas. Methods 179 patients with loose teeth of II ~ III degree or complete teeth dislocations due to traumas (474 teeth in total) were selected in the outpatient department of stomatology in this hospital. Super-bond C&B interproximal bonding (E) was used to fix teeth which were severely loose or in dislocation. This method was compared with the conventional wire ligation method (A), dental arch splint method (B), wire enamel adhesive method (C), and fragments of edgewise technique loose tooth fixation method (D) in terms of periodontal health and fixation effects. Curative effects were also observed. Results Gingival index (GI) and sulcus bleeding index (SBI) of group E were significantly lower than those of group A, B, C, and D (P < 0.01), and its fixation effect was better than that of A, B, C, and D group (P < 0.01). Conclusion For the fixation of anterior teeth traumas, Super-bond C&B interproximal bonding method doesn’t affect much the periodontal health and has reliable curative effects.
