Table 4 Comparison of removal torque values between microimplants with various lengths and diameters

From: Long-term evaluation of factors affecting removal torque of microimplants

  1. Welch’s analysis of variance (ANOVA) test and Dunnett T3 multiple comparison test were performed for comparison between groups of microimplant length in the maxilla. Independent t-test was performed for comparison between groups of microimplant length in the mandible. Kruskal–Wallis test was performed for comparison between groups of microimplant diameter in the maxilla. One-way ANOVA with the post hoc Tukey's test was performed for comparison between groups of microimplant diameter in the mandible
  2. *Significant difference at p < 0.05 between maxillary microimplants with a length of 6 and 8 mm
  3. **Significant difference at p < 0.001 between mandibular microimplants with a length of 6 and 7 mm
  4. †Significant difference at p < 0.001 between mandibular microimplants with a diameter of 1.5 and 1.3 mm or those with a diameter of 1.5 and 1.4 mm
