Rehabilitation of a Patient with Completely Edentulous Maxillary Arch using “All on 4” Concept of Implantation

Treatment options for insufficient ridge morphology includes the use of short implants, vertical ridge augmentation procedures, or cantilever prostheses in completely edentulous patients. Due to the less predictable long-term prognosis associated with the above-mentioned procedures, the “All on 4” technique was proposed for the rehabilitation in edentulous jaws. The All on 4 treatment concept meets the patient requirements with an immediately loaded fixed prosthesis supported by four implants. This article depicts a clinical report in which an “All on 4” implant treatment is done with delayed loading protocol due to inadequate primary stability obtained.
