Design outcomes

Primary

Measure	Time frame
The primary aim of the planned study is to compare the genius of conventional workflow (indirect digitalization) and intraoral digitization (direct digitalization). The accuracy of both workflows should be compared in-vitro and in-vivo. Linear deviations and angular distortions within the model data of both methods are measured.	—

Secondary

Measure	Time frame
The secondary objective of the planned study is to determine the influence of the patient on the collected values of the conventional workflow (indirect digitization) and intraoral digitization (direct digitization). Therefore the in-vivo and the in-vitro values of both workflows should be compared to each other.	—
