Abstract
Objective: this clinical trial was designed to assess the accuracy of bracket placement by indirect bonding by using three dimensional imaging and steroelithographic printing technique.
Materials and methods: a clinical trial was held on ten patients were planned to be bonded by full digital indirect bonding tray for upper arch. Intra- oral scanning of each patient was held after indirect bonding to get STL file for evaluation. Vertical brackets positions of total 120 brackets bonded were measured and evaluated. Intra class correlation and Bland Altman plot test were used to assess the accuracy of vertical bracket position of the full digital transfer tray.

Results: considering the whole units (120 units), excellent reliability and internal consistency (ICC>0.9) with p value < 0.001* with High level of agreement P value =0.089. For lateral incisors, canines and premolar groups, there was good reliability (0.9> ICC>0.75) with high level of agreement with p value = 0.068, 0.706 and 0.794 in order. An acceptable reliability (0.75>ICC>0.5) was found in central incisors and molars groups. The central incisors and molars groups exhibited a proportional bias in agreement test with by P value 0.047 *, 0.019* in order which is clinically insignificant. There was no statistical difference between the mean differences of the five groups P value = 0.185 .with range of mean differences (0.002:0.175) mm which was not clinical significant.
Conclusion: this protocol transferred the planed vertical brackets position from the virtual setup to the patient was generally highly accurate and reliable technique.
