Objectives: Objective: To examine success rates of temporary anchorage devices (TADs) placed by orthodontic residents and to evaluate which factors may affect insertion outcomes.

Methods: Methods: The sample consisted of 85 consecutive TADs placed in 47 patients (20 males and 27 females). TADs were placed at 4 different insertion sites (22 anterior palate (AP), 29 mandibular buccal alveolar process (MDP), 15 maxillary buccal alveolar process (MXP), and 19 palatal alveolar process (PP)). Analysis of variance (ANOVA) test was used to evaluate the influence of insertion sites and anchorage type (direct vs. indirect) on the success rate.

Results: Results: The overall success rate for TADs was 74.2%. The success rate was 77.27% in the AP, 78.95% in PP, 60% in the MXP and 75.86% in MDP. The success rate was significantly higher in indirect anchorage (77.5%) compared to direct anchorage (69.05%).

Conclusions: Conclusions: Palatal TADs were more successful than buccal TADs. Indirect anchorage mechanics had higher success rate than direct anchorage mechanics. Indirect anchorage must be considered when planning orthodontic mechanics with TADs.
