Liu SS-Y, Cruz-Marroquin E, Sun J, Stewart KT, Allen MR. Orthodontic mini-implant diameter does not affect in-situ linear microcrack generation in the mandible or the maxilla. Am J Orthod Dentofacial Orthop 2012;142:768-73.

We recently discovered that the data in Figure 4 were miscalculated in our article. This miscalculation affects not only the presentation of Figure 4 , but also several statements in the Results and Discussion. These are summarized below.

  • 1.

    There is no difference in the total microdamage burden generated in the maxilla vs the mandible.

  • 2.

    In the mandible, pilot drilling produced higher but nonsignificantly different levels of microdamage compared with the control. Insertion of all mini-implants generated more microdamage than in the control, but only insertion of the 1.6-mm and 2.0-mm mini-implants produced more microdamage than in the pilot drilling group.

  • 3.

    Pilot drilling no longer produced more microdamage in the mandible than in the maxilla.

The corrected results lead to the same broad conclusions and clinical implications reported in the published article: that neither the diameter of the mini-implant nor the site of insertion (mandible vs maxilla) had a significant effect on the amount of linear microdamage adjacent to the implant when the implants were inserted after pilot drilling in situ.
