Evaluate clinical outcomes of three single implants with non-splinted crowns and two implants supporting a three unit bridge

There is still a dearth of literature comparing the use of two or three implants in the rehabilitation of three-unit edentulous regions in the posterior jaw region. Therefore, it is of interest to evaluate the clinical outcomes and complications of three single implants with non-splinted crowns (NSC) and two implants supporting a three unit bridge (FDP) with an intervening pontic. Details of 478 patients who had NSC and 456 patients who had FDP were obtained once they fulfilled the standards for inclusion as well as standards of exclusion. Mesial and distal bone height, mobility of implant, peri implantitis (PI) and loss of implants were among the biological complications that were evaluated. The crestal bone loss was lesser in three implants with non-splinted crowns than two implants supporting a three unit bridge with an intervening pontic. The overall complications were also greater in two implants supporting a three unit bridge as compared to three implants with non-splinted crowns.
