A patient has a maxillary complete screw-retained implant prosthesis. What is the appropriate routine maintenance protocol?
Show answer and explanation
Correct answer: A. Periodic professional removal of the prosthesis for maintenance of abutments and edentulous (peri-implant) areas, typically annually
Screw-retained full-arch implant prostheses are designed to be retrievable; periodic professional removal allows thorough cleaning of abutments and the underlying tissues and inspection of components, generally on a scheduled (often annual) basis.Other options: Cleaning only one arch, tightening screws without indication, or skipping maintenance all neglect proper peri-implant care.Key exam takeaway: Screw-retained full-arch prostheses: schedule periodic professional removal to clean abutments and peri-implant tissues.
