| dc.description.tableofcontents | Introduction: The objectives of this study were to analyze and compare the accuracy and intraoperative complications of orthodontic self-tapping and orthodontic self-drilling microscrew placement techniques. Methods: A total of 60 orthodontic microscrews were randomly distributed into 2 study groups: (1) group A, orthodontic selfdrilling microscrew placement technique (n 5 30); and (2) group B, orthodontic self-tapping microscrew placement technique (n 5 30). Cone-beam computed tomography and intraoral scans were performed before and after the orthodontic microscrew placement techniques and uploaded in 3-dimensional implant planning software to analyze the deviation angle and the horizontal deviation measured at the coronal entry point and apical endpoint between orthodontic microscrews planned and performed, using the Student t test. In addition, intraoperative complications, such as root perforations after the orthodontic microscrews placement and the fracture of the orthodontic self-tapping microscrews during their placement, were also analyzed. Results: The paired t test revealed statistically significant differences at the apical endpoint (P\0.001) between planned and performed orthodontic self-tapping and self-drilling microscrew placement techniques. However, the paired t test revealed no statistically significant differences at the coronal entry point (P 5 0.1047) and angular deviations (P 5 0.3251) between planned and performed orthodontic self-tapping and self-drilling microscrews placement techniques. Furthermore, 4 root perforations were observed at the orthodontic selftapping microscrews placement technique, and 1 orthodontic self-tapping microscrew was fractured during the placement procedure. Conclusions: The results show that the orthodontic self-drilling microscrew technique increases the accuracy of orthodontic microscrews placement, resulting in fewer intraoperative complications | es_ES |
