Case 5 3D render, the implant was planned as one piece partial onlay and partial full thickness; the problem encountered was that the implant was a little too big for the void, probably because some fibrotic parts were not visible in the CT; in addition, the thickness of the implant was exactly the same as the actual calvarial bone, and this has led to an increased rate of impingement with the fibrotic tissue, reducing the available space on the intracranial side
