Design outcomes

Primary

Measure	Time frame
The primary endpoint is immediately after implant placement. At this time, an intraoral scan is taken, which is used for superimposition with the initial scan and planning. These data are the basis for the planned evaluation, which is then software-based and computer-assisted. The evaluation of the data between the planned and the achieved implant position is based on the linear and angular deviations in [mm]/[°].	—
