摘要

The topographic features of the base and the retention force of different metal and ceramic orthodontic bracket systems were studied using scanning electron microscopy and dynamometry. A statistically significant effect of the topography and base area of metal and ceramic brackets on their adhesion strength was found (p < 0.01). The highest tangential stress required to detach the brackets from the adhesive was recorded when using brackets made of polycrystalline sapphire (ceramic (Al2O3) with inclusions) with retention balls – 36.45±2.27 MPa (p < 0.01). A statistically significant inverse proportional relationship between the tangential stresses and bracket-adhesive contact area was found (p < 0.01).
