During an update of data used in a library shipped with Exoplan or made available on the download portal of Exocad, it was found that the use of a specific combination of an implant, sleeve and drill in a surgical kit can result in a hole being drilled for the implant 2mm too deep. In case an implant 260-340-256 of Bicon with a 4mm diameter and 6mm length is used in a fully-guided surgery procedure using a 4mm diameter Bicon sleeve it should only be possible to select a drill with 6mm length. But erroneously uses an 8mm length drill (instead of 6mm length drill) from the surgical kit. Recall start date: April 24, 2023
