Seven-Year Follow-up of Full-Arch Prostheses Supported by Four Implants: A Prospective Study

Abstract

For the 12 patients who attended the recall after 7 years, implant loss was not found, the implant stability was high, MBL was low, and prosthetic complications were easily solved. Thus, it can be concluded that rehabilitation with implant-supported mandibular full-arch fixed prostheses with four implants has proved to be a treatment with a high survival rate.
