Younes F, et al. - Researchers compared the accuracy of free-handed (FH), pilot-drill guided (PG) and fully guided (FG) implant surgery in partially edentulous patients. They randomly allocated partially edentulous patients in need of ≥2 implants in the posterior maxilla to 1 of the following treatment groups: FH, PG and FG. As per findings, FG surgery ought to be considered the gold standard approach, during the requirement of perfect implant positioning. Nonetheless, for all implants, screw-retained restorations were planned, in the FH group, 5 of 26 and in the PG group, 1 of 24 had to be restored by means of a cement-retained restoration.
