Fixed implant-supported prostheses are securely attached to dental implants embedded in the jawbone, offering a permanent solution that doesn't require removal for cleaning. These are much like natural teeth in their feel and function, providing a high level of stability and comfort.
On the other hand, removable implant-supported prostheses, also known as implant-supported dentures, can be detached for cleaning and maintenance. They are anchored onto implants for a more secure fit than traditional dentures, but they offer the flexibility of removal, which some patients prefer for ease of cleaning and comfort.
In essence, the choice between the two depends on personal preferences, lifestyle, and specific dental needs, with fixed prostheses offering a more permanent, low-maintenance solution, while removable ones provide flexibility and ease of maintenance.
