Abstract: With the improvement of dental implant restoration technique and people’ living level, as well as the enhancement of people's awareness of oral health care, more and more patients with dentition defects and loss take implant repair as the first choice. All-on-4 or All-on-X immediate loading technique of edentulous patients not only greatly shortens the period of tooth loss, but also reduces the number of operations and saves time and cost, thus improving the quality of life of patients. The principle of All-on-4 is to use four implants in the mouth of patients with edentulous jaws to support a temporary, fixed, and immediately weight-bearing prosthesis. Many scholars at home and abroad have made clinical follow-up for patients with All-on-4 immediately loading, and obtained positive clinical effects, but there are also certain failure rates and postoperative complications. In this paper, the possible causes and postoperative complications of failure in All-on-4 immediate weight-bearing prosthesis are analyzed, with aim to provide reference for basic level dentists who will develop All-on-4 or All-on-X immediate loading restorations for edentulous patients.
