title: Clinical accuracy outcomes of closed-tray and open-tray implant impression techniques for partially edentulous patients.
abstract: The aim of this research was to compare the accuracy outcomes of open- and closed-tray implant impressions for partially edentulous patients. Eleven partially edentulous spaces in seven patients with two existing implants for fixed partial dentures were included. Group I (closed-tray) and group II (open-tray) were compared using microcomputed tomography scanning. No statistically significant differences were found between the closed- and open-tray techniques (P = .317). The subjective evaluation of patient comfort showed no differences with either impression technique. There were no differences seen between open- and closed-tray impression techniques in partially edentulous patients when implants had less than 10 degrees of angulation.
