Fixed and removable prostheses are dental appliances used to replace missing teeth and restore normal oral function. Fixed prostheses, such as crowns, bridges, and implants, provide a permanent solution, whereas removable prostheses, including full and partial dentures, offer flexibility for patients who prefer non-permanent solutions. The choice between fixed and removable prostheses depends on factors such as bone structure, patient preference, and budget. Fixed options provide superior stability and aesthetics but require a longer and sometimes more invasive procedure. Removable prostheses, on the other hand, are easier to clean and adjust. Both types of prostheses improve chewing efficiency, speech, and facial aesthetics, restoring confidence and comfort for patients.
