Fully Edentulous (when a person is missing all of their teeth) dental implants have remarkably improved how the teeth of individuals who are edentulous or partially edentulous can be restored. Implants for the rehabilitation and retention of dental and facial prostheses have graduated from a phase of wishful thinking to one of the most gratifying experiences for patients and treating fraternity alike. From 4.3% after five years to 26.4% after 10 years, the frequency of connection-related problems (screw loosening or fracture) increased (in patients who are fully edentulous). Of the 9% of restorations that were cemented, loss of retention of the restorations occurred in 6.2% within five years and 24.9% within 10 years. – The Etiology and Management of Dental Implant Failure: A Review by NIH
