Immediate loading of two (fixed-on-2) versus three (fixed-on-3) implants placed flapless supporting cross-arch fixed prostheses: One-year results from a randomised controlled trial

摘要

Purpose: To evaluate the outcome of two (fixed-on-2 = FO2) versus three (fixed-on-3 = FO3) implants placed flapless in fully edentulous jaws and immediately restored with metal-resin screw-retained crossarch prostheses.
