Abstract
In managing loose abutment screws, locating precisely the position of the screw access
channel is difficult. This technique describes the use of cone-beam computed tomography
(CBCT) and surgical guide planning software to locate the screw access channel with
the intention of retrieving a loosened cement-retained implant-supported prosthesis.
The method minimizes damage to the abutment crown assembly.
