Objective In addition to examining the transmission accuracy of rigid and non-rigid IDB's the aim of the study is to determine the 'lost rate' during the placement. The 'lost rate' is the percentage frequency of brackets that have no adhesion to the model after the bonding has taken place. Hypothesis The main hypothesis does not describe a significant deviation of the digitally planned to the actually placed bracket position in directions and angles described. The secondary hypothesis is the assumption of no significant difference between the accuracy and lost rate of the two materials. Method 24 orthodontic patients treated with multibracket appliance will be included for the planned study. In order to increase the reproducibility of the acquired data four different model situations are included. Objective The aim of the study is a scientific examination of the accuracy of digital printed bonding trays using two materials to support the decision process of the potential user and their dental laboratories. The study allows an insight into the technical manufacturing process and its workflow.
