About

The aim of this study is to comparatively investigate the performances of two different and widely used transfer trays during indirect bonding of the orthodontic braces.

Full description

The aim of the study is to compare the accuracy of orthodontic bracket and tube transfer between double layer silicone and double layer vacuum formed trays. The sample included 368 attachments bonded in 16 patients. Each patient received one silicone and one vacuum formed tray which were randomly allocated to provide 8 trays of each type for the upper and lower arches. 3D scan data and local best-fit alignments were used to calculate the translational and rotational movements of the orthodontic attachments. Chi-square and Mann-Whitney U tests were used to compare transfer accuracy and success between the groups.
