| Sumario: | ABSTRACT: Objective: To analyze the level of survival and the main complications presented by total edentulous patients after the All-on-Four® treatment, through a retrospective analysis. Methods: The medical records of 32 rehabilitated patients, between 2010 to 2018 were selected, presenting a total of 128 implants with subsequent fixed prostheses. The following variables were analyzed: gender, age, patient’s systemic condition, time of implant installation, number of implants, and surgical and prosthetic complications. Results: The procedures were performed over on average 5.9 years ago and were more prevalent in female patients(59.6%). Out of the 32 patients selected 75% presented some systemic alteration, with hypertension being the most frequent disease. Regarding the implant placement, the rehabilitation in the mandible was more prevalent(62.5%), while in the maxilla(31.2%), and in the bimaxillary region(6.25%). As for the complications, out of 128 implants installed, 13 presented loss of osseointegration, leading to a survival rate of 90.44% (94.3% mandible and 83.3% maxilla). Furthermore, 15 surgical and 20 prosthetic complications were diagnosed. Among the surgical complications, the most frequent were loss(5-33%) and bone fracture(3-20%), while the most frequent prosthetic complications included loosening and/or or fracture of the prosthetic component and prosthetic fracture (6-30%). Conclusion: All-on-Four® is a procedure that has a high survival rate. |
