IDI Fixture Mount Abutment can be cut/modified to become a provisional abutment, where a temporary crown can be placed immediately.

Warning: However, the device is intended for immediate loading ONLY when good primary stability has been achieved and with appropriate occlusal loading

In some cases, especially in aesthetic zone, immediate non-functional loading may be applicable, which means there is no centric and eccentric occlusal contact on temporary restorations.

However, Paulo Malo did suggest all-on-4 technique for immediate full arch provisional restoration.
