How is a full-arch prosthesis replaced?

Replacement begins with removing the old prosthesis via the access screws. New impressions are taken of the integrated implants. Dental technicians fabricate a new prosthesis based on the current jaw anatomy. Colour and shape can be adjusted to reflect the ageing process. The average replacement interval is 10 to 15 years for fixed systems. The cost is 30 to 50% of the original prosthesis price. Removable systems need replacing more often (every 5 to 8 years). Technological advances (e.g. digital scans) speed up the process. Patients keep their implants during replacement. Regular check-ups identify in good time when replacement is needed.
