[From the concept of permanent percutaneous connections to that of permanent percutaneous electrical connections].

Percutaneous abutment of an extra-oral implant provides two main functions: support of bone anchored hearing aid (BAHA) and fixing maxillofacial prosthesis (MFP). Further developing this concept, and using available surgical strategies and materials, leads to a new application in extra-oral implantology. We analyzed the evolution of concepts in the field of permanent percutaneous connection (PPC) to the new concept of PPEC (permanent percutaneous electric connection), presenting a clinical case.
