TYPES OF IMPLANT PROSTHESIS
The prostheses can be unitary, partial or total. The choice of one or the other should be customized in each case. TOTAL FIXED PROSTHESIS: Its function is to rehabilitate the entire mouth when all the teeth of one or both arches are missing. The full-arch dental prostheses that are screwed or cemented on six or eight osseointegrated implants. These restorative dentistry treatments replace all the teeth of one or both arches with a prosthesis or "fixed denture" fixed on a reduced number of dental implants, which fulfill the biomechanical functions of the natural roots of the teeth. To clean them, the dentist must unscrew the prosthesis, which is fixed on the dental implants: so the patient has to periodically go to revisions to keep his prosthesis in perfect condition. REMOVABLE PROSTHESIS: They are removable prostheses that are placed on dental implants. As a general rule, fewer dental implants are needed than with a fixed prosthesis, (usually four) and may be indicated for patients with greater loss of bone tissue in the maxilla. Instead of directly screwing the prosthesis to the implants, it is fixed by a series of indirect techniques, with the possibility of being removed by the patient for better oral hygiene.
