The clinical frequency of fractures of adhesive brackets


, : The clinical frequency of fractures of adhesive brackets. Fortschritte der Kieferorthopaedie 49(6): 522-528

Direct bracket-bonding has many advantages since it means improved prophylaxis of caries and of periodontitis. Separation of teeth prior to bonding and the closure of band spaces are no longer necessary. In addition aesthetics is much better compared to conventional bands. However, an important disadvantage of direct bonding appears to be the failure rate. The present study shows that after 38 months merely 93.4% of maxillary brackets and 90.4% of mandibular brackets are still in place. Two thirds of those brackets which were finally lost failed after 15 months. In about 90% of the investigated failures the fracture was observed to be between the bracket metal and the adhesive.
