Patient with a maxillary complete screw-retained implant prosthesis. What is regular care?
Show answer and explanation
Correct answer: D. Regular removal for maintenance
- A. While abutment/tissue hygiene matters, this alone is insufficient — periodic professional removal for full inspection/cleaning is the recommended standard.
- B. This question concerns maxillary prosthesis maintenance, not lower arch hygiene specifically.
- C. Routine screw tightening 'as needed' is not the standard recommended maintenance protocol; well-torqued screws should not require periodic re-tightening as a matter of course.
- D. Correct. Annual (or periodic) removal of a full-arch screw-retained implant prosthesis by the dental professional for thorough cleaning/inspection of the prosthesis and underlying tissue is the recommended standard of care.
Note: Annual removal for professional maintenance is recommended for full-arch implant prostheses.
